BackgroundHearing screening is an important part of prevention. It allows early detection of hearing disorders, allowing treatment to begin early and eliminating or minimizing negative consequences. Children with hearing impairment often experience delayed speech development and cognitive abilities, which can result in learning disabilities and reduce school progress. Since 1999, the Institute of Physiology
and Pathology of Hearing in Poland has provided a hearing screening program for school-aged children in the country. The main aim of the
program is the early detection of hearing disorders, especially in children starting school, and to increase the awareness of parents and the
school more generally about hearing problemsMaterial and MethodsThere were 6,297 children from the Warmian – Masurian Voivodeship enrolled in the program (3,050 girls; 3,247
boys) from grades 1 to 6 and aged between 6 and 13 years. Hearing screening was conducted over two time-frames: from September 2014 to
June 2015, and from September 2015 to June 2016. Most of the children were from the first group: 81.1% of all pupils examined. Each child
was assessed by pure tone audiometry and a questionnaire addressed to parents.ResultsBased on the result of the audiogram, screening showed that hearing impairment was found in 1169 (18.6%) of the examined pupils.
Of these, 64.5% (750 children) had single-sided hearing lossConclusionsThe results confirm that awareness of hearing disorders in Poland is low. Many school-age children have hearing loss, but it
is often not detected by caregivers and teachers. Even small hearing losses may cause difficulties in communication, emotional reactions,
or learning. Early detection of hearing disorders is therefore crucial. A screening program can quickly identify patients with hearing loss
and implement appropriate treatment and rehabilitation as soon as possible, actions that can improve the quality of life of the children
and their families.

ObjectiveThe present study aimed at standardizing the phonemically balanced word lists in the Kannada language for adults developed by
Manjula et al. (2015).Materials and MethodsForty individuals with different degrees of sensorineural hearing loss were enrolled for the study. The word lists developed by Manjula et al. (2015) were presented monaurally under headphones at 40 dB SL (ref: PTA) in quiet. The number of correctly identified words was calculated for each list. The scores of all the lists in each group were statistically analyzed.ResultsThe results revealed that there is list equivalency within each group on repeated measures ANOVA. The statistical analysis also revealed that the speech identification scores reduced significantly with an increase in the severity of hearing loss on MANOVA.ConclusionsThe lists developed by Manjula et al. (2015) are sensitive to different degrees of hearing loss. Hence, the lists can be a good speech
identification tool for testing adults with hearing loss in routine speech identification testing, assessing hearing aid benefits, and for research
purposes where multiple word lists are required.

Published: May 2021

BackgroundChronic suppurative otitis media (CSOM) in early childhood can lead to auditory processing disorders in later life even though
the hearing sensitivity has returned to normal. There is a dearth of studies in the literature that have evaluated the auditory processing in
children with later onset of CSOM.Material and MethodsAuditory processing was measured in terms of frequency discrimination (difference limen frequency, DLF), intensity
discrimination (difference limen intensity, DLI), and gap detection threshold (GDT) in 15 children with CSOM of mean age 13 years as well
as in 15 normal hearing children of comparable age.ResultsAn independent t-test was used to gauge the significance between the groups for all three parameters. There was a statistically significant difference (p < 0.05) for all three.ConclusionsThe results confirm that conductive hearing loss impairs the auditory processing abilities of children with CSOM, even in those
aged 9 to 15 years. These findings highlight the importance of early intervention in cases of CSOM.
ANTERIOR COURSE OF THE SIGMOID SINUS
AND USE OF A LIFT WITH THE BONEBRIDGE
IMPLANT: CASE REPORT

Published: May 2021

BackgroundThe Bonebridge bone conduction implant (BCI) is used in cases of conductive, mixed hearing loss and single-sided deafness.
The system can be implanted in the mastoid process pre- or retrosigmoidally. Presigmoid placement tends to reduce the number of subsequent implantations. The use of new refinements – such as spacers called BCI lifts, which facilitate adjustment during surgery – broadens the
applicability of Bonebridge to a larger group of patients.Case reportThis case study presents a 58-year-old female patient with bilateral chronic otitis media who had undergone several operations
in the past and who qualified for a Bonebridge implant. During surgery, a lift for the lower screw of the bone-conduction floating mass transducer (BC-FMT) was used because of an anterior course of the sigmoid sinus. We analysed hearing results before and 3 months after the surgery. The results indicated stable bone conduction thresholds and improved hearing and speech recognition after implantation.ConclusionsThe Bonebridge system is an effective treatment for hearing loss caused by chronic otitis media in cases where classic otosurgery cannot be performed. Difficult conditions during surgery, as caused by an anterior sigmoid sinus, can limit the use of the Bonebridge.
In such cases use of a lift can widen implantation options.

Published: May 2021

BackgroundSpeech is a stimulus with high redundancy because the information in it is conveyed in several ways simultaneously. Because
of redundancy, a regular speech identification test is largely insensitive to identifying high frequency hearing loss in a subject. The present
study aimed to develop and standardise a word list in the Nepali language in which the selected words have elevated high frequency content.Material and MethodsThe study was conducted in three phases. The first stage was to develop a high frequency word list, which was completed by gathering familiar bisyllabic words, recording them, and then selecting words dominant in high frequencies. In stage 2, the developed word list was administered to 100 individuals with normal hearing. In stage 3, the final lists were administered to 10 individuals with
simulated high frequency hearing loss in order to determine the usefulness of the list. Finally, 7 psychometrically equivalent word lists with
20 words per list were developed.ResultsNormal hearing individuals showed Speech Identification Scores of more than 95% whereas in the case of the simulated high frequency loss group, significantly poorer speech identification scores were obtained.ConclusionsThis present study standardised high frequency word lists in Nepali and all the lists were validated in subjects with simulated
high frequency hearing loss. Hence, this can be used as a standard high frequency word list in the Nepali population.

IntroductionThere are many reasons for an increase in volume of the salivary glands, including inflammatory changes due to infection, autoimmune and allergic reactions, endocrine disorder, tumor, or injury.AimPresentation of a rare case of a pneumoparotidCase reportA 54-year-old patient was admitted to the department for diagnosis of a nodular swelling in the area of the left parotid gland.
The swelling had appeared about 3 weeks earlier, initially with pain, and had gradually increased in size. He denied head or neck injury,
problems with chewing or swallowing food, or a dry mouth. Laryngological examination revealed swelling of the cheek in the left preauricular area, palpably soft, oval-shaped (about 20 x 15 mm), slightly painful when pressed, non-fluctuant, and with no associated skin changes.
Fine-needle aspiration biopsy and contrast CT scan of the neck revealed a pneumoparotid on the left side. After decompression of the pneumoparotid, conservative treatment (a pressure dressing) was applied in an outpatient mode. Due to lack of therapeutic effect, the patient was
qualified for surgical excision of the left pneumoparotid.ConclusionsA pneumoparotid of the salivary glands is a rare pathology affecting the parotid glands and is associated with an increase in intraoral
pressure. Treatment is primarily avoidance of the triggering factor and pressure dressings, but sometimes surgery is necessary. The pathology in most
cases does not cause permanent damage to the salivary glands and the effects of treatment are good.

ObjectiveTo determine mean hearing thresholds for 18-year-old, otologically healthy subjectsStudy designProspective historical cohort studyMethodsAs part of a follow-up study of a birth cohort, followed from age 2 to 18 years, meticulous otological examination
including history-taking, otoscopy, and audiometry were available. At age 18, both air-conduction thresholds (0.25 kHz to 8
kHz and 8 kHz to 16 kHz) and bone-conduction thresholds (0.5 kHz to 4 kHz) were measured. Subjects of this cohort were
defined as otologically healthy if they had not experienced substantial otitis media in childhood.ResultsOn both ends of the frequency range of air-conduction testing, measured thresholds deviated statistically significantly from the ISO 389 reference zero. The air-conduction thresholds were comparable to data presented in the literature. Furthermore, a misfit with the ISO 389 reference was found at 2 and 3 kHz for bone-conduction testing. Only the mean boneconduction thresholds at 0.5 kHz and 4 kHz were not significantly different from the ISO 389 reference zero. To explain the
deviations at high frequencies, noise exposure was considered but thought unlikelyConclusionsThis study cohort seems to be the best representative sample so far of otologically healthy subjects due to the
longitudinal study of their otological status. Mean hearing thresholds at age 18 are different from the ISO 389 reference zero,
suggesting once more the need to revise this ISO norm.
THE EFFECT OF HEARING LOSS ON THE SIBLING
RELATIONSHIP

Published: May 2021

AimThe aim of the study was to analyze the brother or sister bond in individuals whose siblings have hearing loss, and to see
whether variables such as age, sex, age-difference of siblings, and family characteristic affected the relationship.Material and MethodsThis study included 20 individuals who had normal-hearing siblings and 20 individuals who had
hearing-impaired siblings. The latter were children and adolescents of the Training Unit of Hearing and Speaking Abilities at
Hacettepe University, Department of ENT, Audiology and Speech Pathology Section, Turkey. The siblings in question were
over 12 and had normal hearing. A ‘General Information Form’ was used to gather information about the individuals who
participated in the study and their hearing-loss siblings; a ‘Sibling Relationship Questionnaire’ was used to gauge relationships between siblings.ResultsIn general, individuals having a sibling with hearing loss had considerably higher scores on the subscales warmth/
closeness and relative power/status than those having normal-hearing siblings (p<0.05). Likewise, individuals having normalhearing siblings had higher scores on the subscales “conflict” and “rivalry” than those in the other group (p<0.05).ConclusionsExistence of a hearing-impaired child in the family affects the sibling relationship. Growing up with a hearingimpaired sibling brings changes to the daily life of normal children. Individuals having a sibling with hearing loss have less
conflict and rivalry and more intimacy/fondness in their sibling relationship. We infer that these children have developed an
ability to help their siblings.

Published: May 2021

BackgroundPitch relates to the low frequency temporal content of sound, which mainly depends on phase coding at the level of the auditory nerve. In this study, we aim to assess the detectibility of pitch changes in different populations of hearingimpaired subjects suffering from sensorineural hearing loss in order to identify possible poor temporal coding.Material and MethodsA number of tests – part of the A§E (ASSE or Auditory Speech Sounds Evaluation) psychoacoustic
test suite – were used to assess the perception of pitch changes in adults with a hearing loss (a) in the high frequencies with
or without classical hearing aids, (b) in the low frequencies, and (c) in a group of cochlear implant users. All test stimuli were
controlled for their fundamental frequency (F0), which either remained stable during the stimulus presentation or which,
simulating intonation, glided from F0 to F0+∆. Isolated synthetic complexes were used as well as pseudo-words or pseudosentences mimicking linguistically relevant contexts. The subjects were asked to distinguish these sounds in either identification or discrimination tasks.ResultsHearing-impaired subjects, and particularly those with low-frequency hearing loss, performed significantly worse in
comparison to hearing adults on all tests. The use of a hearing aid did not yield significant improvements. The cochlear implant users experienced great difficulty in performing the tests.ConclusionThe intonation tests of A§E2009 are a useful diagnostic tool to distinguish hearing-impaired subjects based on
their capacity to process low-frequency information. The tests may be of particular use in the evaluation of the impact of auditory rehabilitation, hearing aids, or electro-acoustic stimulation.
AUDIOLOGICAL FINDINGS AND AIDED PERFORMANCE IN
INDIVIDUALS WITH AUDITORY NEUROPATHY SPECTRUM
DISORDER (ANSD) – A RETROSPECTIVE STUDY
Authors: Jijo P. , Yathiraj Asha 
Published: May 2021

BackgroundThere is controversy in the literature regarding the utility of amplification in individuals with auditory neuropathy spectrum disorder (ANSD). Most of the studies regarding the effect of amplification on speech perception in ANSD have
been carried out on children. Only a few investigations have studied this aspect in late onset ANSD. The majority of these studies report no aided improvement, with only a few reporting minimal benefit. Further, none of the studies in late onset ANSD
evaluated the relation between audiological test results and aided improvement.AimThe study aimed to investigate the effect of amplification on speech identification scores (SISs) in individuals with late
onset ANSD. It also determined a relation between audiological test results and aided improvement.MethodThe retrospective study was carried out by reviewing the clinical records of 64 patients with late onset ANSD.ResultsImprovement in speech identification with hearing aids was observed in 30% of the ears evaluated. Correlation analysis
revealed that there was a significant positive correlation between SISs obtained under headphones and aided performance. However, no relation was found between the degree of hearing loss and the aided performance or on the unaided sound field SIS.ConclusionsUnlike earlier studies, it was found that individuals with late onset ANSD did show improvement in speech perception when using hearing aids. The SIS under headphones was a major indicator of aided performance in adults with late
onset ANSD.
PEDIATRIC COCHLEAR IMPLANT RECIPIENTS IN INDIA:

AND CORRELATION WITH OUTCOMES

Published: May 2021

BackgroundRehabilitation centres for cochlear implant (CI) recipients act as gateways for increasing auditory perception and
developing speech and language. In the case of children, such centres must strive not only to get the best outcomes in terms
of hearing and speech, but they must also provide satisfaction to both CI recipients and their parents. To gauge the quality
of service, we have divided the range of services offered into four areas and have assessed the specific and overall satisfaction
levels of parents of CI children towards these services.Material and MethodsThis was a prospective, randomized, cross-sectional study based on a questionnaire provided to CI users of rehabilitation centers in Tamil Nadu, India. The parents of 100 CI recipients younger than 6 years were asked to fill in
a questionnaire using a 5-point rating scale. The education level of the care-taker and the time spent with the child at home
were also ascertained, and these factors were correlated with CI performance outcomes (categories of auditory performance,
CAP, and speech intelligibility rating, SIR).ResultsThe overall satisfaction level of the parents was reasonably high (mean=3.9, SD=0.44). There was a positive correlation of satisfaction score with rehabilitation outcomes (r=0.80 for CAP; 0.29 for SIR). The level of education of the parents
had no correlation with the outcome either for CAP (r=0.15) or SIR (r=0.07). Time spent by the parents with the CI recipient
at home gave r-values of 0.31 for CAP and 0.39 for SIR.ConclusionsThe general level of satisfaction of parents towards the services provided by the rehabilitation centres was good. In
terms of best CI outcome, the time spent by the parents with their child was more important than the parents’ education level.
COEXISTENCE OF BILATERAL SULCUS VERGETURE AND BILATERAL FIBROUS MASS OF THE VOCAL FOLDS: CASE REPORT
Authors: Miaskiewicz Beata , Szkielkowska Agata 
Published: May 2021

BackgroundThis study presents the case of a 32-year old woman who presented with severe dysphonia. She had experienced voice problems since childhood.Material and MethodsThe patient underwent otolaryngological and phoniatric examination including videolaryngostroboscopy (VLS), perceptual evaluation (GRBAS scale), and acoustic analysis of voice (MDVP software). Microsurgery was performed using a CO2 Acupulse laser (Lumenis) with AcuBlade micromanipulator.ResultsVLS revealed glottal incompetence, an intracordal mass on the right vocal fold, and capillary ectasia on the superior surface of the right vocal fold. Atrophy was seen along the free edge of the left vocal fold. GRBAS and MDVP revealed significant voice disturbances. The patient was referred for direct microlaryngoscopy. Initial inspection of the vocal folds showed bilateral intracordal mass and sulcus vergeture. Using a microflap technique the fibrous mass was removed. For the sulcus vergeture a surgical technique based on a concept by Cornut and Bouchayer and modified by Remacle was used. Complementary hyaluronic acid (Surgiderm 24XP) was injected to correct the left vocal fold volume. Stroboscopic evaluation performed 3 months postoperatively showed significant improvement of glottis closure and vibratory parameters. Perceptual and objective voice assessment revealed improvement in the acoustic structure of the voice after surgeryConclusionsCoexistence of bilateral sulcus vergeture and bilateral fibrous mass is a very rare occurrence. The preoperative diagnosis is often not obvious. Severe voice disturbances make surgery the first treatment option in such cases.
EFFECT OF CARNATIC VOCAL MUSIC TRAINING AND
EXPERIENCE ON CORTICAL AUDITORY EVOKED POTENTIALS
Authors: Sanju Himanshu , Nikhil J. , Kumar Prawin 
Published: May 2021

BackgroundA musician’s ability to produce a precise pitch must involve some kind of neuroplasticity, allowing them to control fundamental frequency, maintain target pitch, and accurately control pitch through auditory perceptual monitoring. The
present study uses cortical auditory evoked potentials (CAEPs) to investigate neuroplasticity by assessing the latency of P1,
N1, P2, and N2 as well as the peak-to-peak amplitudes P1–N1, N1–P2, and P2–N2 in two groups of subjects: Carnatic vocal
musicians and non-musicians.Material and MethodsTwo groups of normal hearing females aged 18 to 25 years. There were 20 Carnatic vocal musicians
(Indian classical music of south India) and 20 non-musicians. Pure tones were used as stimuli.ResultsDescriptive statistics revealed lower latency and greater peak-to-peak amplitude for all measures in the Carnatic vocal musicians compared to the non-musicians. MANOVA showed that vocalists had significantly better (shorter) N1, P2, and
N2 latencies and significantly better (greater) peak-to-peak amplitude of P1–N1.ConclusionsThe present study showed some significantly enhanced CAEP parameters in Carnatic vocal musicians compared
to non-musicians. This indicates that musical experience has an effect on the central auditory nervous system, and this form
of neuroplasticity can be investigated with CAEPs.

Published: May 2021

ObjectiveTo analyze the literature on wideband immittance testing and to evaluate the success of these procedures in evaluating middle ear function in newborns.MethodsA systematic literature review was conducted using as keywords: wideband, tympanometry, reflectance, absorbance, immittance. Papers which did not address neonates were excluded from the review. From each article specific information was extracted referring to the following: sample size, population characteristics, equipment, stimulus type, study evaluation, and study conclusion.ConclusionsThis systematic review considers that wideband immittance is a promising way for evaluating middle ear function in neonates. It is necessary to establish regulatory standards for different age groups of neonates and infants.
