Objective To investigate the association between cleft size in infancy and crossbite at 5 years of age in children with cleft palate (CP) and unilateral cleft lip and palate (UCLP). Design Retrospective study. Setting University Hospital, Uppsala, Sweden. Patients Dental study models of 80 consecutive children, 51 children with CP and 29 children with UCLP, born between 1990 and 1999 were analyzed. Interventions Lip repair at 3 to 4 months in UCLP children. Primary soft palate repair at 6 to 10 months and secondary hard palate closure at 25 to 26 months of age. Main Outcome Measures Maxillary arch dimensions and cleft size were measured on infancy dental casts. At follow-up at 5 years, crossbite scores were registered on dental study models. Results The cleft dimensions in infancy showed large interindividual variation. Mean posterior cleft width was larger in UCLP children than in children with CP. The UCLP group also had significantly more crossbite at 5 years than the CP group. No significant association was noted between initial cleft size and crossbite scores at 5 years in the CP group. For the UCLP group, larger cleft widths at the level of the cuspid points were significantly associated with less anterior and posterior crossbite. Conclusions The findings support the hypothesis that cleft size in infancy affects early outcome with respect to crossbite in children with UCLP, but not in children with CP.

Published: October 2018

Background and Purpose Alveolar bone grafting remains the standard for alveolar cleft repair. Compromised oral and/or nasal closure may impede healing and result in graft failure or persistent fistulae. Incorporating acellular dermal matrix into these repairs may protect the bone graft during mucosal healing by providing an additional layer of soft tissue coverage. Methods A retrospective review of alveolar bone grafts undertaken at our cleft–craniofacial center from 2005 to 2007 was performed. The use of acellular dermal matrix for nasal and/or oral lining augmentation was determined. A minimum 3 months’ follow-up was required for inclusion. Outcomes included (1) mucosal disruption, (2) time to complete mucosal healing, (3) bone graft exposure, (4) postoperative bone graft incorporation using the Chelsea scale, and (5) canine eruption through the graft site. Results In total, 35 patients were included. Of those, 15 patients (four girls, 11 boys; seven Veau III, eight Veau IV) received acellular dermal matrix for mucosal augmentation (five nasal, one oral, nine nasal and oral lining). Average age at surgery was 10 years (range, 9 to 16 years). Average follow-up was 23 months (range, 3 to 35 months). Mucosal disruption occurred in 20% of the acellular group and in 30% of the control group ( p = nonsignificant). Complete mucosal healing was achieved at an average of 4 weeks (range, 1 to 14 weeks) in the acellular dermal matrix group versus 4 weeks (range, 2 to 11 weeks) in the control group ( p = nonsignificant). Exposure of bone graft occurred in 0% of the acellular dermal matrix group and in 30% of the control group ( p = .016). The Chelsea scale demonstrated no significant radiographic difference in postoperative bone graft incorporation between the acellular dermal matrix and control groups. Canine eruption through the graft site was similar for both groups. Conclusions These data support the conclusions that using acellular dermal matrix to augment nasal/oral mucosal lining in alveolar bone grafts (1) does not increase mucosal disruption or time to complete healing, (2) prevents postoperative bone graft exposure, and (3) appears to have no negative effect on postoperative bone graft incorporation or canine eruption through the graft site.

Published: October 2018

Objective Apert syndrome has been extensively studied and described. However, an area that has not been studied is the dental development of these Individuals. The purpose of this study was to evaluate the development of the dentition and compare it with that of unaffected children. There appears to be clinical observations Indicating delayed eruption of the permanent teeth in the Apert child. Methods This retrospective study examined all Apert syndrome patients from four craniofacial centers who had a panoramic radiograph taken before the age of 16 years. Thirty-six individuals, 19 boys and 17 girls ranging In age from 4.1 to 15.8 (mean = 9.3) years were examined. The seven left mandibular permanent teeth, second molar to central incisor, were rated on an eight-stage scale (A–H) using methods described by Demirjian and Goldstein (1976). The stage of each tooth was converted to the corresponding numeric value, and then all seven values were added to obtain a dental maturity score, which corresponded to a dental age, based on the sample of 4500+ normal children of the Demirjian et al. study. The dental age and chronologic age were compared using a paired t test. The correlation between chronologic age and length of delay was also determined. Results Thirty-one of 36 individuals had a dental age lower than their chronologic age. Compared to the normal sample, the mean developmental dental delay was 0.96 years (p < .001). The range in delay was 0.5 years advanced to 2.9 years delayed. There was a positive correlation to increased age with greater delay in dental development (p < .05). Conclusion Our study confirmed our clinical impressions: The results showed a mean developmental delay of 0.96 years, with a trend of Increasing delay with increased age. This positive correlation found between increased age and increased delay parallels the general growth of Apert children, with a greater degree of delay as the child grows older.

Published: October 2018

Objective This study was conducted to evaluate the relationship between size of residual clefts in the hard palate and speech. Subjects Fifteen 7-year-old children born with complete cleft lip and palate were investigated. Methods All of the children were treated according to a surgical regimen involving early soft palate repair and delayed hard palate closure. Measures were taken of the area, length, and maximal width of the residual cleft in the hard palate about a year before Its closure and correlated with a perceptual judgment of several speech variables. Results Significant positive correlations were obtained between the size of the cleft and two variables: weak pressure consonants and hypernasality. Nasal escape was very common among the patients, and almost half the children had retracted palatal or velar articulation of dental stop consonants. Neither of these two variables correlated with the size of the residual cleft. Conclusion Perceived oral pressure and, perhaps, resonance seem to be related to size of the opening of the residual cleft, whereas audible nasal escape and articulatory compensations are not, at least not the latter once established.

Published: October 2018

Objective This investigation was conducted to determine the agreement between three-dimensional (3-D) calculations from CAT scans and two-dimensional (2-D) calculations from standard dental radiographs in evaluating bone support for cleft-adjacent teeth after primary bone grafting. Design This retrospective study utilized CAT scans and dental radiographs taken of the alveolar cleft in patients an average of 11 years after primary bone grafting. Setting The subjects were patients treated by the Cleft Palate Team at Children's Memorial Hospital and Loyola University Medical Center, Chicago, Illinois. Patients Fourteen UCLP patients (9 males, 5 females) agreed to participate In this study by undergoing CAT scan assessment of their alveolar cleft sites. They also had to have periapical or occlusal radiographs of the grafted cleft site taken within 6 months of the CAT scan. Interventions All patients underwent primary lip repair, placement of a passive palatal plate, primary alveolar bone grafting (mean age 6.4 months), and palatoplasty before 1 year of age. Major tooth movement through final orthodontics was completed by the time of the radiographic assessment. Main Outcome Measures CAT scan sections were reformatted and reconstructed to three-dimensionally calculate the percentage of root covered by bone support for the 15 teeth adjacent to the grafted cleft sites. Dental radiographs of the same teeth were also traced and digitized. Percentages of root supported by bone were also established using the dental radiographs by dividing the amount of root covered by bone, by the anatomic root length. Results A paired, two-sample t test revealed no significant differences between the two methods of assessment, while linear regression showed a statistically significant correlation between the CAT scan assessment and the percentages found on the radiographs. Conclusions Routine dental radiographs were able to estimate the total 3-D bone support for the roots of cleft adjacent teeth as determined by CAT scan to a statistically significant degree when groups where compared. The clinical significance for evaluation of individual cases was less impressive with a wide range of variability and a level of agreement that required acceptance of differences up to 25%.

Published: October 2018

Objective This study assessed the reproducibility, reliability, and predictive validity of a previously developed index by the authors for assessing surgical outcome in unilateral cleft lip and palate (UCLP) children aged 5. Methods Sixty randomly selected study models of 5- to 6-year-old complete UCLP subjects were obtained and the index was used to assess their surgical outcomes. Results Assessment of these study models using the new index demonstrated excellent intra-examiner agreement. The inter-examiner agreement was shown to be good. The corresponding longitudinal models at 16 to 18 years of 54 of the initial 5- to 6-year-old sample were also acquired. These subjects had undergone orthodontic treatment but not orthognathic surgery. The need for osteotomy amongst these models was assessed. Between 13% and 18% (depending on examiner) of 5-year-olds' models were scored in the groups likely to require orthognathic surgery. In the corresponding 16- to 18-year-olds' models, 9% were assessed as likely to benefit from an osteotomy. However, on an individual basis, it was not possible to predict future growth from study models at age 5. Conclusions This study has provided a reliable and reproducible index for assessing the outcome of surgery in UCLP subjects earlier than indices already available. True validation of the Index was not possible but it appears that it relies on face validity.
Comparison of Numeric Techniques in the Analysis of Cleft Palate Dental Arch Form Change
Authors: McAlarney Mona E. , Chiu Wei-Kwang 
Published: October 2018

Objective: Quantitative descriptions of form (size and shape) changes are significant to the understanding of the development, treatment planning, and prognosis of patients born with cleft lip and palate. This study compared the results of traditional dental arch form change measurements, such as width, depth, perimeter, and area, with four numeric methods: finite element scaling analysis, macroelement method, Euclidean distance matrix analysis, and conventional least-squares and resistant-fit theta rho Procrustes analyses. Design: Using tooth cusp landmarks on maxillary study casts, form change measurements of a male with complete bilateral cleft lip and palate at ages 2, 5, and 6 years were made comparing each age to the next older. Results and Conclusions: With the exception of the 2- to 5-year resistant-fit analysis, all numeric methods: 1) provide comparable results, 2) provide more detailed descriptions than do traditional methods, and 3) provide results that correlate well with the reported effects of increased lip pressure due to lip closure surgery. The use of finite-element scaling analysis on study casts is somewhat limited since: 1) there is more than one solution at teeth shared by many finite elements, 2) gross averaging of form change occurs within triangular elements, and 3) solutions can vary with the choice of element location. The use of the macroelement method circumvented the above finite element limitations with out compromising finite-element advantages. Procrustes results vary with the chosen superposition algorithm. The choice of the most appropriate Procrustes method required some a priori knowledge of form difference. The large number of results obtained by Euclidean distance matrix analysis and the nongraphic presentation of these results hamper quick interpretation but may be best suited for definitive statistical analysis. The graphic representation of both the magnitude and direction of: 1) landmark displacement in the Procrustes analyses (once size difference is eliminated), and 2) the rate of form change in the macroelement method provide an intuitive appreciation of how and where the casts differ.

Published: October 2018

Objective: This study, using mongrel dogs, attempted to delineate the respiratory activity of two closure muscles of the velopharynx, the levator veli palatini (LVP) and superior pharyngeal constrictor (PC) muscles. Method: Fifteen mongrel dogs were given tracheotomies, with intratracheal tubes being connected to their respiratory circuits. Activities of the PC and LVP muscles were recorded electromyographically, and the effects of Pao2 and Paco2 were analyzed along with the effects of lung inflation intratracheally with O2 and N2. Results: Under hypoxic conditions, expiratory LVP activity was observed while PC activity diminished. The effects of lung inflation on both LVP and PC activities were also studied. The activities of both muscles were enhanced by lung inflation. Conclusion: It was thus suggested that the roles of both muscles during velopha-ryngeal closing movements are not the same.
Facial and Speech Relationships to Behavior of Children with Clefts across Three Age Levels
Authors: Richman Lynn C. 
Published: October 2018

Objective: This study was conducted to examine relationships of facial and speech ratings to behavior at three ages. Design: Multiple correlations to control for gender, IQ, and socioeconomic status (SES). Partial correlations between speech or facial ratings and behavior. Setting: A university hospital interdisciplinary cleft/craniofacial center. Patients: Sixty-five children with CP or CLP and no other anomalies seen at ages 6,9, and 12 years. Interventions: Speech ratings, facial ratings, hearing assessment, and SES ratings, were collected at ages 6,9, and 12. Main Outcome Measure: The Behavior Problem Checklist was used and internalizing problems were expected. Results: Less severe speech problems associated with behavioral inhibition were noted at age 9 years (p < .01). Greater facial disfigurement was correlated with greater inhibition at age 12 (p < .001). Conclusions: Longitudinal data indicates different associations of speech and facial variables were made to behavior at different ages (9 and 12). No significant relationships were identified at age 6.
Craniofacial Morphology in Patients with Kallmann's Syndrome with and without Cleft Lip and Palate
Authors: Mølsted Kirsten , Kjær Inger , Giwercman Aleksander , Vesterhauge Søren , Skakkebæk Niels Erik 
Published: October 2018

Objective: Kallmann's syndrome is characterized by the association of hypogonadotropic hypogonadism and anosmia or hyposmia. The principal endocrine defect of hypogonadotropic hypogonadism is a failure to secrete luteinizing hormone-releasing hormone (LHRH), resulting in underdevelopment of the pituitary gonadotropes and an inability to synthesize and release luteinizing hormone and follicle-stimulating hormone. The purpose of the present investigation was to describe the dentition and the craniofacial morphology in patients diagnosed with Kallmann's syndrome. Design: The sample consisted of 11 patients, 2 of whom also had bilateral cleft lip and palate. Radiographic investigations, including cephalometry, were performed. Comparisons were made to normal individuals and to cleft lip individuals without Kallmann's syndrome. Results: Dentition: tooth agenesis occurred more frequently in patients with Kallmann's syndrome. Craniofacial morphology: Increased mandibular inclination and mandibular angulation were seen in Kallmann patients. When clefting also occurred, extreme retrognathism of both maxilla and mandible was seen, a deviation which seemingly worsened during growth. The anterior cranial base and the sphenoid bone showed an altered morphology in one of the patients with Kallman's syndrome. Conclusions: An early diagnosis of Kallmann's syndrome is very important because the prognosis for endocrine treatment thereby improves, and therefore, it is recommended that the sense of smell be evaluated in patients with the craniofacial morphology described.
Effect of Alveolar Bone Grafting in the Mixed Dentition on Maxillary Growth in Complete Unilateral Cleft Lip and Palate Patients
Authors: Daskalogiannakis John , Ross R. Bruce 
Published: October 2018

Objective: This study was conducted to evaluate the effects on facial growth of alveolar bone grafting in the mixed dentition for patients with UCLP. Design: Retrospective cephalometric study. Setting: Craniofacial Treatment and Research Centre, The Hospital for Sick Children, Toronto, Ontario, Canada. Patients: The 58 patients participating in the study had a history of complete unilateral cleft lip and palate, all of which were repaired by the same plastic surgeon. Interventions: Twenty-one patients received an iliac-crest alveolar bone graft at a mean age of 10.3 years, while 37 did not receive an alveolar bone graft. Lateral cephalometric radiographs were obtained on all patients at two different times: at a mean age of 9.4 years (prior to bone grafting in the grafted group) and at a mean age of 15.2 years. Main Outcome Measures: All radiographs were traced and digitized by the same person, using cephalometric computer software. Superimposition and cephalometric analysis was undertaken to investigate the differences between the two groups in the 5.6-year experimental period. A two-way analysis of covariance was used for evaluation of the statistical significance of the results. Results: No statistically significant differences were found in 14 of the 15 cephalometric measurements performed. Harvold's maxillary unit length was statistically significantly shorter in the grafted group, although a lack of correlation with angular measurements and inherent problems with this specific measurement raise doubts in this finding. Conclusion: Mixed dentition bone grafting does not affect subsequent vertical and A-P development of the maxilla in complete unilateral cleft lip and palate patients during the first several postoperative years.
Structure of the Musculus Uvulae: Functional and Surgical Implications of an Anatomic Study
Authors: Huang Martin H. S. , Lee S. T. , Rajendran K. 
Published: October 2018

Objective: The role of the musculus uvulae in velopharyngeal function, its morphologic status in cleft palate, and its fate in palatoplasty procedures are subjects of controversy. The aims of this investigation were to re-examine this velar muscle to clarify its anatomic characteristics, to analyze its role in speech physiology, and to study the surgical implications of this information for cleft palate repair. Methods: Its attachments, morphology, and relations were examined in 18 fresh human adult cadavers by detailed dissection under 3.2× magnification and light microscopy. Results: The musculus uvulae was observed to be a paired midline muscle extending between the tensor aponeurosis anteriorly and the base of the uvula posteriorly along the nasal aspect of the velum. It had no attachments to the hard palate. Conclusions: These findings suggest that its action is to increase midline bulk on the nasal aspect of the velum, thus contributing to the levator eminence. It may also have an extensor effect on the nasal aspect of the velum, displacing it toward the posterior pharyngeal wall. Both of these actions would serve to maximize midline velopharyngeal contact. One clinical application of this anatomic information is that the muscle should be preserved in the dissection performed during intravelar veloplasty. Furthermore, it should be recognized that the musculus uvulae is invariably divided and reoriented incorrectly in the Furlow double opposing Z-plasty.
