Speech in 5-year-olds born with unilateral cleft lip and palate: a Prospective Swedish Intercenter Study

Studies on the impact of cleft palate surgery on speech with stringent methodology are called for, since we still do not know the best timing or the best method for surgery. The purpose was to report on speech outcome for all Swedish-speaking 5-year-olds born with a non-syndromic unilateral cleft lip and palate (UCLP), in 2008–2010, treated at Sweden’s six cleft palate centres, and to compare speech outcomes between centres. Speech was assessed in 57 children with percent consonants correct adjusted for age (PCC-A), based on phonetic transcriptions from audio recordings by five independent judges. Also, hypernasality and perceived velopharyngeal function were assessed. The median PCC-A for all children was 93.9, and medians in the different groups varied from 89.9 to 96.8. In the total group, 9 children (16%) had more than mild hypernasality. Twenty-two children (38.5%) were perceived as having competent/sufficient velopharyngeal function, 25 (44%) as having marginally incompetent/insufficient velopharyngeal function, and 10 children (17.5%) as having incompetent/insufficient velopharyngeal function. Ten children were treated with secondary speech improving surgery and/or fistula surgery. No significant differences among the six groups, with eight to ten children in each group, were found. The results were similar to those in other studies on speech of children with UCLP, but poorer than results in normative data of Swedish-speaking 5-year-olds without UCLP. Indications of differences in frequency of surgical treatment and speech treatment between centres were observed.

title: Palatoplasty: evolution and controversies.
abstract: Treatment of cleft palate has evolved over a long period of time. Various techniques of cleft palate repair that are practiced today are the results of principles learned through many years of modifications. The challenge in the art of modern palatoplasty is no longer successful closure of the cleft palate but an optimal speech outcome without compromising maxillofacial growth. Throughout these periods of evolution in the treatment of cleft palate, the effectiveness of various treatment protocols has been challenged by controversies concerning speech and maxillofacial growth. This article reviews the history of cleft palate surgery from its humble beginnings to modern-day palatoplasty, and describes various palatoplasty techniques and commonly used modifications. Current controversial issues on the timing of cleft palate repair, and the effects on speech and maxillofacial growth are also discussed.

title: Scandcleft randomised trials of primary surgery for unilateral cleft lip and palate: 4. Speech outcomes in 5-year-olds - velopharyngeal competency and hypernasality
abstract: Adequate velopharyngeal function and speech are main goals in the treatment of cleft palate. The objective was to investigate if there were differences in velopharyngeal competency (VPC) and hypernasality at age 5 years in children with unilateral cleft lip and palate (UCLP) operated on with different surgical methods for primary palatal repair. A secondary aim was to estimate burden of care in terms of received additional secondary surgeries and speech therapy.  Three parallel group, randomised clinical trials were undertaken as an international multicentre study by 10 cleft teams in five countries: Denmark, Finland, Sweden, Norway, and the UK.  Three different surgical protocols for primary palatal repair were tested against a common procedure in the total cohort of 448 children born with a non-syndromic UCLP. Speech audio and video recordings of 391 children (136 girls, 255 boys) were available and perceptually analysed. The main outcome measures were VPC and hypernasality from blinded assessments.  There were no statistically significant differences between the prevalences in the arms in any of the trials.  No differences were found regarding VPC and hypernasality at age 5 years after different methods for primary palatal repair. The burden of care in terms of secondary pharyngeal surgeries, number of fistulae, and speech therapy visits differed.

title: Scandcleft randomised trials of primary surgery for unilateral cleft lip and palate: 5. Speech outcomes in 5-year-olds - consonant proficiency and errors
abstract: Normal articulation before school start is a main objective in cleft palate treatment. The aim was to investigate if differences exist in consonant proficiency at age 5 years between children with unilateral cleft lip and palate (UCLP) randomised to different surgical protocols for primary palatal repair. A secondary aim was to estimate burden of care in terms of received additional secondary surgeries and speech therapy.  Three parallel group, randomised clinical trials were undertaken as an international multicentre study by 10 cleft teams in five countries: Denmark, Finland, Norway, Sweden, and the UK.  Three different surgical protocols for primary palatal repair were tested against a common procedure in the total cohort of 448 children born with non-syndromic UCLP. Speech audio- and video-recordings of 391 children (136 girls and 255 boys) were available and transcribed phonetically. The main outcome measure was Percent Consonants Correct (PCC) from blinded assessments.  In Trial 1, arm A showed statistically significant higher PCC scores (82%) than arm B (78%) (p = .045). No significant differences were found between prevalences in Trial 2, A: 79%, C: 82%; or Trial 3, A: 80%, D: 85%. Across all trials, girls achieved better PCC scores, excluding s-errors, than boys (91.0% and 87.5%, respectively) (p = .01).  PCC scores were higher in arm A than B in Trial 1, whereas no differences were found between arms in Trials 2 or 3. The burden of care in terms of secondary pharyngeal surgeries, number of fistulae, and speech therapy visits differed.

title: Centre-level variation in speech outcome and interventions, and factors associated with poor speech outcomes in 5-year-old children with non-syndromic unilateral cleft lip and palate: The Cleft Care UK study. Part 4.
abstract: To investigate centre-level variation in speech intervention and outcome and factors associated with a speech disorder in children in Cleft Care UK (CCUK).



Two hundred and sixty-eight 5-year-old British children with non-syndromic unilateral cleft lip and palate recruited to CCUK.



Centre-based therapists undertook audio-video recordings. Perceptual analysis was undertaken using the CAPS-A tool. Speech outcomes were based on structural and articulation scores, and intelligibility/distinctiveness. Between-centre variation in treatment and outcomes were examined using multilevel models. These models were extended to estimate the association between a range of factors (hearing loss, speech intervention, fistula, secondary speech surgery for velopharyngeal insufficiency, socio-economic status, gender, and parental happiness with speech) and speech outcomes.



There was centre-level variation in secondary speech surgery, speech intervention, structure and intelligibility outcomes. Children with a history of speech intervention had a lower odds of poor intelligibility/distinctiveness, 0.1 (95% CI: 0.0-0.4). Parental concern was associated with a higher odds of poor intelligibility/distinctiveness, 13.2 (95% CI: 4.9-35.1). Poor speech outcomes were associated with a fistula, secondary speech surgery and history of hearing loss.



Within the centralized service there is centre-level variation in secondary speech surgery, intervention and speech outcomes. These findings support the importance of early management of fistulae, effective management of velopharyngeal insufficiency and hearing impairment, and most importantly speech intervention in the preschool years. Parental concern about speech is a good indicator of speech status.

title: A Cross-Sectional Study of Speech in 10-Year-Old Children with Cleft Palate: Results and Issues of Rater Reliability
abstract: To describe speech based on perceptual evaluation in a group of 10-year-old children with cleft palate. A secondary aim was to investigate the reliability of speech-language pathologists’ perceptual assessment of cleft palate speech.  Retrospective cross-sectional study in children with cleft palate. External raters made assessments from randomized speech recordings.  Thirty-eight children with unilateral cleft lip and palate (UCLP) or cleft palate only (CPO) and 10 children in a comparison group.  Ratings of hypernasality, hyponasality, audible nasal air leakage, weak pressure consonants, and articulation. Exact agreement and weighted kappa values were used for reliability.  Hypernasality was found in 25% of children with a cleft of the soft palate (CSP), 33% of children with a cleft of the hard and soft palate (CHSP), and 67% of children with a UCLP. Similar results were found for audible nasal air leakage. Articulation errors were found in 6% of the CHSP group and 25% of the UCLP group, whereas no child in the CSP group had articulation errors. The reliability was moderate to good for different variables, with lowest values for hypernasality.  Speech results in this series seem less satisfactory than those reported in other published international studies, but it is difficult to draw any certain conclusions about speech results because of large methodological differences. Further developments to ensure high reliability of perceptual ratings of speech are called for.

title: Issues in perceptual speech analysis in cleft palate and related disorders: a review.
abstract: Perceptual speech assessment is central to the evaluation of speech outcomes associated with cleft palate and velopharyngeal dysfunction. However, the complexity of this process is perhaps sometimes underestimated.



To draw together the many different strands in the complex process of perceptual speech assessment and analysis, and make recommendations for practice.



This review examines issues such as data sampling, data collection/recording, archiving, the advantages and disadvantages of lay and specialist listeners, approaches to data analysis, reliability, and data interpretation.



The need to capture meaningfully the sound of speech based on detailed phonetic analysis is argued. Also described are some of the differences in measuring speech for clinical, audit and research activities. Blind independent analysis of speech data by specialist therapists is recommended as the gold standard methodological approach when reporting audit and research outcomes. The requirement for ongoing training in listening skills for specialist therapists is advocated. The limitations of an impairment-based-only approach to measurement are also illustrated, indicating the need to develop outcome measures that incorporate more functional issues that affect quality of life.

title: The Americleft Speech Project: A Training and Reliability Study
abstract: To describe the results of two reliability studies and to assess the effect of training on interrater reliability scores.  The first study (1) examined interrater and intrarater reliability scores (weighted and unweighted kappas) and (2) compared interrater reliability scores before and after training on the use of the Cleft Audit Protocol for Speech–Augmented (CAPS-A) with British English-speaking children. The second study examined interrater and intrarater reliability on a modified version of the CAPS-A (CAPS-A Americleft Modification) with American and Canadian English-speaking children. Finally, comparisons were made between the interrater and intrarater reliability scores obtained for Study 1 and Study 2.  The participants were speech-language pathologists from the Americleft Speech Project.  In Study 1, interrater reliability scores improved for 6 of the 13 parameters following training on the CAPS-A protocol. Comparison of the reliability results for the two studies indicated lower scores for Study 2 compared with Study 1. However, this appeared to be an artifact of the kappa statistic that occurred due to insufficient variability in the reliability samples for Study 2. When percent agreement scores were also calculated, the ratings appeared similar across Study 1 and Study 2.  The findings of this study suggested that improvements in interrater reliability could be obtained following a program of systematic training. However, improvements were not uniform across all parameters. Acceptable levels of reliability were achieved for those parameters most important for evaluation of velopharyngeal function.

title: Incidence of Cleft Lip and Palate and Risks of Additional Malformations
abstract: Children with cleft lip and/or palate (n 5 251) born between 1991 and 1995 in the county of Stockholm, Sweden, were studied with reference to incidence and rate ratios (RRs) of different types of clefts, gender, birth weight, mother’s age, and length of pregnancy. Children who had clefts and additional malformations were compared with children who had clefts but no additional malformations.  The incidence of clefts was 2.0/1000 live births, and it was higher among males than among females. The RR, an index of relative risk, was 1.58. The main groups, children with isolated cleft lip, children with cleft lip and palate, and children with isolated cleft palate, showed similar incidence values (0.6–0.7/1000 live births). Children with bilateral clefts had an incidence of 0.3/ 1000 live births. Additional malformations were found in approximately every sixth newborn with a cleft when children with Robin sequence were excluded. There was a tendency for newborns with bilateral clefts to have additional malformations (RR 5 1.36; confidence interval 5 0.74–2.49). Children with clefts and additional malformations had lower birth weight and were born earlier than children with clefts only.  Preterm cleft children with low birth weight should be screened for the presence of other birth defects.

title: SVANTE – The Swedish Articulation and Nasality Test – Normative data and a minimum standard set for cross-linguistic comparison
abstract: Normative language-based data are important for comparing speech performances of clinical groups. The Swedish Articulation and Nasality Test (SVANTE) was developed to enable a detailed speech assessment. This study’s aim was to present normative data on articulation and nasality in Swedish speakers. Single word production, sentence repetition and connected speech were collected using SVANTE in 443 individuals. Mean (SD) and prevalences in the groups of 3-, 5-, 7-, 10-, 16- and 19-year-olds were calculated from phonetic transcriptions or ordinal rating. For the 3- and 5-year-olds, a consonant inventory was also determined. The mean percent of oral consonants correct ranged from 77% at age 3 to 99% at age 19. At age 5, a mean of 96% was already reached, and the consonant inventory was established except for /s/, /r/, /ɕ/. The norms on the SVANTE, also including a short version, will be useful in the interpretation of speech outcomes.

title: Speech in 5-Year-Olds With Cleft Palate With or Without Cleft Lip Treated With Primary Palatal Surgery With Muscle Reconstruction According to Sommerlad
abstract: To evaluate speech in 5-year-olds with cleft palate with or without cleft lip (CP±L) treated with primary palatal surgery in 1 stage with muscle reconstruction according to Sommerlad at about 12 months of age.  Retrospective study.  Primary care university hospital.  Eight 5-year-olds with cleft soft palate (SP), 22 with cleft soft/hard palate (SHP), 33 with unilateral cleft lip and palate, and 17 with bilateral CLP (BCLP).  Percent oral consonants correct (POCC), percent consonants correct adjusted for age (PCC-A), percent oral errors, percent nonoral errors, and variables related to velopharyngeal function were analyzed from assessments of audio recordings by 3 independent speech-language pathologists.  The median POCC was 75.4% (range: 22.7%-98.9%), median PCC-A 96.9% (range: 36.9%-100%), median percent oral errors 3.4% (range: 0%-40.7%), and median percent nonoral errors 0% (range: 0%-20%), with significantly poorer results in children with more extensive clefts. The SP group had significantly less occurrence of audible nasal air leakage than the SHP and the BCLP groups. Before age 5 years, 1.3% of the children underwent fistula surgery and 6.3% secondary speech improving surgery. At age 5 years, 15% of the total group was perceived as having incompetent velopharyngeal function.  Speech was poorer in many children with more extensive clefts. Children with CP±L had poorer speech compared to normative data of peers without CP±L, but the results indicated relatively good speech compared to speech of children with CP±L in previous studies.

title: A Longitudinal Study of Speech Production in Swedish Children with Unilateral Cleft Lip and Palate and Two-stage Palatal Repair
abstract: To describe speech production longitudinally in a group of children with unilateral cleft lip and palate (UCLP).  Twenty consecutive children with UCLP and nine age-matched children without clefts in a comparison group.  A two-stage palatal repair procedure with soft palate closure at 6 months and hard palate repair at 3 to 4 years.  Percent correct consonants (PCC), percent correct places (PCP), and percent correct manners (PCM) at 3, 5, and 7 years of age. Cleft speech errors at the same ages. Previously collected data on number of consonant tokens, consonant types, frequency of occurrence of places and manners of articulation at 18 months.  PCC and PCP were significantly lower in the UCLP group than in the comparison group at all ages. Number of consonant types and frequency of occurrence of dental plosives at 18 months correlated significantly with PCC at age 3. A high frequency of velar plosives at 18 months correlated significantly with a high prevalence of retracted oral articulation (dental/alveolar to palatal or velar) at both 3 and 5 years of age.  The UCLP group performed worse than the comparison group at all ages. A high occurrence of dental plosives as well as a high number of consonant types in babbling and first words seem to be good indicators for better consonant production in later speech. The same prevalence of retracted oral articulation as in previous studies is attributed to the surgical technique.

title: Speech outcomes at age 5 and 10 years in unilateral cleft lip and palate after one-stage palatal repair with minimal incision technique - a longitudinal perspective.
abstract: To investigate speech outcomes in 5- and 10-year-old children with unilateral cleft lip and palate (UCLP) treated according to minimal incision technique (MIT) - a one-stage palatal method.



A retrospective, longitudinal cohort study of a consecutive series of 69 patients born with UCLP, treated with MIT (mean age 13 months) was included. Forty-two children (43%) received a velopharyngeal flap; 12 before 5 years and another 18 before 10 years of age. Cleft speech variables were rated from standardized audio recordings at 5 and 10 years of age, independently by three experienced, external speech-language pathologists, blinded to the material. The prevalences of cleft speech characteristics were determined, and inter- and intra-rater agreement calculated.



More than mild hypernasality, weak pressure consonants and perceived incompetent velopharyngeal function were present in 19-22% of the children at 5 years, but improved to less than 5% at 10 years. However, audible nasal air leakage, prevalent in 23% at 5 years, did not improve by age 10. Thirty percent had frequent or almost always persistent compensatory articulation at 5 years, and 6% at age 10. The general impression of speech improved markedly, from 57% giving a normal impression at 5 years to 89% at 10 years. A high prevalence of distorted/s/was found at both 5 and 10 years of age.



A high occurrence of speech deviances at 5 years of age after MIT was markedly reduced at 10 years in this study of children with unilateral cleft lip and palate. The high pharyngeal flap rate presumably accounted for the positive speech development.

title: Long-Term, Longitudinal Follow-Up of Individuals with Unilateral Cleft Lip and Palate after the Gothenburg Primary Early Veloplasty and Delayed Hard Palate Closure Protocol: Speech Outcome
abstract: To investigate long-term, longitudinal speech outcome in patients born with unilateral cleft lip and palate treated according to a two-stage primary palatal protocol with early veloplasty and delayed hard palate closure.  Retrospective, longitudinal cohort study.  A university hospital in western Sweden. Subjects A consecutive series of 55 patients from the total cohort of 65 were included. All patients had surgical procedures at Sahlgrenska University Hospital, Gothenburg, Sweden.  Standardized audio recordings were blindly analyzed at 5, 7, 16, and 19 years of age and after at a clinical visit at 10 years of age. Typical cleft speech variables were rated independently on ordinal scales. Intelligibility and perceived velopharyngeal function were assessed also. Prevalences of speech characteristics were determined, and interrater and intrarater agreement were calculated.  Prominent hypernasality, nasal air leakage, and retracted oral articulation at 5 years were markedly reduced throughout the years with low prevalences at ages 16 and 19 years. Perceived velopharyngeal competence was noted in 82% at age 16 and 87% at age 19 years along with normal intelligibility. Pharyngeal flap surgery was performed in 6 of the 55 patients (11%).  Long-term speech outcome in patients with two-stage palatoplasty with early soft palate repair was considered good and improved even before hard palate repair. The typical retracted oral articulation was quite frequent during the early ages; whereas, nonoral misarticulations were almost nonexistent, implying good velopharyngeal competence.

title: Speech Production of Preschoolers with Cleft Palate
abstract: The present investigation was conducted to examine the prevalence of preschoolers with cleft palate who require speech therapy, demonstrate significant nasalization of speech, and produce compensatory articulations. The relationship among these three dependent variables and the independent variables of cleft type and age of primary palatal surgery was also examined.  The participants included 212 preschoolers with repaired cleft palate aged 2 years 10 months to 5 years 6 months.  Chi-square analyses were performed to examine the relationship between two independent variables (cleft type and age of surgery) and three dependent variables (percentage of children requiring speech therapy, percentage demonstrating moderate to severe hypernasality and receiving secondary management for velopharyngeal insufficiency, and percentage producing glottal/pharyngeal substitutions).  Sixty-eight percent of the children were enrolled in (or had previously received) speech therapy. Thirty-seven percent of the children demonstrated moderate-severe hypernasality or had received secondary surgical management for velopharyngeal insufficiency. Chi-square analyses revealed a significant relationship between cleft type and the number of children referred for speech therapy as well as the number of children with significant hypernasality. The analyses also revealed a significant relationship between age of palatal surgery and number of children with significant hypernasality.  Despite advances in surgical management and the advantages offered by team care, the majority of preschoolers with cleft palate continue to demonstrate delays in speech sound development that require direct speech therapy. An optimal treatment regimen for these children is one that includes primary palatal surgery no later than 13 months of age.

title: Hearing thresholds and ventilation tube treatment in children with unilateral cleft lip and palate.
abstract: Children with cleft lip and palate have a high prevalence of otitis media with effusion (OME) which is often associated with a fluctuating, conductive hearing loss in the low and mid-frequencies and a risk for permanent hearing loss in the higher frequencies. Although common, there is no consensus on the treatment of OME with ventilation tubes. The aim of this study is to document if the risk for permanent hearing loss and acquired cholesteatoma increases due to treatment with ventilation tubes (VT treatments) during childhood in a group of children with cleft lip and palate.



A retrospective medical chart review of 33 children (25 boys and 8 girls) born with unilateral cleft lip and palate (UCLP) was completed. Audiological data (results of hearing sensitivity tests, the total number of hearing tests, and number of VT treatments) were extracted from medical records from when the children were 4-7 and >7-10 years of age.



The hearing thresholds in the speech frequencies improved with age (p < 0,05) but a minority of the children continued to present with elevated hearing thresholds in the higher frequencies at >7-10 years of age. There were no significant correlations between number of VT treatments and hearing thresholds at >7-10 years. Four of the 33 children presented with complications: two children exhibited perforations of the ear drum (6.1%) and two children developed unilateral cholesteatoma (6.1%).



In the current study, the hearing sensitivity of children with cleft lip and palate improved with age. However, this improvement was not seen in the higher frequencies. Twelve percent of the children experienced complications following VT treatments. Due to these complications, it is recommended that all children with cleft palate should have routine follow-ups by an ENT doctor and audiologist. As part of the routine follow-up care, hearing assessments should be performed before and after VT treatments.

title: Otitis media and speech and language: a meta-analysis of prospective studies.
abstract: Considerable controversy surrounds whether a history of otitis media with effusion (OME) in early childhood causes later speech and language problems. We conducted a meta-analysis of prospective studies to determine: 1) whether a history of OME in early childhood is related to receptive language, expressive language, vocabulary, syntax, or speech development in children 1 to 5 years old and 2) whether hearing loss caused by otitis media in early childhood is related to children's receptive language or expressive language through 2 years of age.



We searched online databases and bibliographies of OME studies and reviews for prospective or randomized clinical trials published between January 1966 and October 2002 that examined the relationship of OME or OME-associated hearing loss in early childhood to children's later speech and language development. The original search identified 38 studies, of which 14 had data suitable for calculating a pooled correlation coefficient (correlational studies) or standard difference between parallel groups (group studies). Random-effects meta-analysis was used to pool data when at least 3 studies had usable data for a particular outcome.



We performed 11 meta-analyses. There were no significant findings for the analyses of OME during early childhood versus receptive or expressive language during the preschool years in the correlation studies. Similarly, there were no significant findings for OME versus vocabulary, syntax, or speech during the preschool years. Conversely, there was a significant negative association between OME and preschoolers' receptive and expressive language (lower language) (0.24 and 0.25 standard difference, respectively) in the group studies. Additionally, hearing was also related to receptive and expressive language in infancy (3%-9% of variance).



Our results indicate no to very small negative associations of OME and associated hearing loss to children's later speech and language development. These findings may overestimate the impact of OME on outcomes, because most studies did not adjust for known confounding variables (such as socioeconomic status) and excluded data not suitable for statistical pooling, especially from methodologically sound studies. Although some OME language differences were detectable by meta-analysis due to increased statistical power, the clinical relevance for otherwise healthy children is uncertain.

title: Speech and Language Therapy Interventions for Children with Cleft Palate: A Systematic Review
abstract: To examine the evidence for the effectiveness of differences in timing and type of speech and language therapy for children with cleft palate with or without a cleft lip and (2) to identify types of interventions assessed.  Nine databases, including MEDLINE and EMBASE, were searched between inception and March 2011 to identify published articles relating to speech and language therapy for children with cleft palate with or without cleft lip. Studies that included at least 10 participants and reported outcome measures for speech and/or language measures were included. Studies where the experimental group had less than 90% of children with cleft palate with or without cleft lip were excluded. Two reviewers independently completed inclusion assessment, data extraction, and risk of bias assessment for all studies identified.  A total of 17 papers were evaluated: six randomized control trials and 11 observational studies. Studies varied widely on risk of bias, intervention used, and outcome measures reported. None of the studies had a low risk of bias. In terms of intervention approaches, seven studies evaluated linguistic approaches and 10 evaluated motor approaches. Outcomes measures did not support either approach over the other, and based on data reported it was difficult to ascertain which approach is more effective for children with cleft palate with or without cleft lip.  The review found little evidence to support any specific intervention. Key uncertainties need to be identified and adequately powered, methodologically rigorous studies conducted to provide a secure evidence base for speech-language therapy practice in children with cleft palate with or without cleft lip.

title: Two-Stage Palatal Surgery with Early Veloplasty and Delayed Hard Palate Repair: A Balanced View on Speech and Midfacial Growth Outcome
abstract: Today, there is general consensus that, particularly, the protocol for repair of the palate is crucial for normal speech development and adequate long-term midfacial growth in individuals affected with cleft lip and palate (CLP). About 90 years ago, a new two-stage palatal repair method was introduced. It was characterized by early veloplasty and later closure of the hard palate. Recent follow-up studies of this regimen have revealed excellent long-term outcome regarding maxillary growth and also satisfactory speech development, even if the hard palate surgery was delayed to the stage of early mixed dentition. A speech deviation, coined as “retracted oral articulation of anterior pressure consonants,” seemed to be a relatively common speech error, temporarily affecting about one third of our preschool children born with unilateral CLP. The prevalence of other, more severe cleft speech characteristics, such as symptoms of and related to velopharyngeal incompetence and the occurrence of glottal misarticulations in particular, was very low.

title: A Technique for Cleft Palate Repair
abstract: The author has developed a technique of palate repair that combines minimal hard palate dissection with radical retropositioning of the velar musculature and tensor tenotomy. The repair is performed under the operating microscope. Results are reported for 442 primary palate repairs performed between 1978 and 1992 inclusive, with follow-up of at least 10 years. In 80 percent of these palate repairs, repair was carried out through incisions at the margins of the cleft and without any mucoperiosteal flap elevation or lateral incisions. Secondary velopharyngeal rates have decreased from 10.2 to 4.9 to 4.6 percent in successive 5-year periods within this 15-year period. Evidence from independent assessment of speech results in palate re-repair and submucous cleft palate repair suggests that this more radical muscle dissection improves velar function.

title: Minimal incision palatopharyngoplasty. A preliminary report.
abstract: A new palatopharyngoplasty which allows good muscular reorientation as well as elongation of the soft palate with minimal morbidity and scarring has been developed, and 66 selected patients underwent the procedure during the period September 1989 to March 1993. The most important findings were reduced operative bleeding, good length and mobility of the soft palate, and minimal scarring. A total of seven fistulas (11%) developed. Twenty-three patients (mean age 6 years and 2 months at the time of operation) underwent nasopharyngoscopy and multiview videofluoroscopy; velopharyngeal insufficiency was evident in only four (17%). Dental casts were obtained in 14 patients (mean age at the time of the operation 1 year, 3 months) who were followed up for a maximum period of two years. No postoperative orthodontic treatment was required and the width and harmony of the dental arch were maintained in all cases.

title: Phonology in Swedish-speaking 5-year-olds born with unilateral cleft lip and palate and the relationship with consonant production at 3 years of age
abstract: At ∼3 years of age ∼50% of the children born with cleft palate present with phonological/articulatory difficulties. Differences between children with and without cleft palate have been reported to decline with age; however, the phonology in children with cleft palate at pre-school age/early school age has rarely been explored. The purpose of this study was to assess phonology in children with unilateral cleft lip and palate (UCLP) at age 5 and its relationship with performances at 3 years of age.  The study included 29 children with UCLP and 20 without UCLP. Percentage correct consonants adjusted for age (PCC-A) and number of consistent phonological simplification processes were assessed from phonetic transcriptions. In addition, a descriptive analysis of phonological/articulatory processes was performed.  The children with UCLP displayed significantly lower PCC-A and more phonological processes at age 5 years than peers without UCLP. The correlations between the outcomes at 3 and 5 years of age were significant.  Still at 5 years of age many children with cleft palate have phonological problems and it is possible to identify children at risk for impaired phonology at earlier age.

title: Influence of surgeon's experience on speech outcome in cleft lip and palate
abstract: Relation between the number of cases treated and outcome, particularly in low-incidence anomalies, are difficult to identify and rectify. We show clear advantages in speech outcomes for children born with a cleft lip and palate who are operated on by surgeons who do large numbers of these procedures.
