INVESTIGATING THE SATISFACTION
OF CLINICIANS AND CLIENTS
IN A TELEAUDIOLOGY TRIAL
Authors: Thrum Michael , Driscoll Carlie , Keogh Tegan 
Published: May 2021

BackgroundThus far, the uptake of telehealth in Australia has been puzzlingly small in scale and sporadic in nature. This is particularly
true of audiology. The current study aimed to investigate the satisfaction of clinicians and clients with audiology appointments in a trial of
the telehealth mode.Material and MethodsA mixed-methods study design was utilised involving surveys with all appointment participants and semi-structured
post-appointment interviews with clients. Appointments were conducted with 11 individual clients; of these, 7 interviews were conducted.
One audiologist and one allied health assistant were used for all appointments.ResultsHigh satisfaction ratings overall were given by both clients (87.3% excellent) and the allied health assistant (74.4% excellent), whereas the audiologist consistently provided slightly lower levels of satisfaction (72.7% good). It was also found that the audiologist believed that
teleaudiology increased the quality of care offered.ConclusionsBy examining the perspectives of all key stakeholders, this study identifies a number of novel positive and negative aspects of a
teleaudiology practice and offers suggestions for future implementation of such a program.
DEVELOPMENT AND STANDARDISATION
OF HIGH FREQUENCY WORD IDENTIFICATION
TEST FOR ADULTS IN GUJARATI LANGUAGE
Authors: Mehta Gunjan , Neupane Anuj 
Published: May 2021

BackgroundEvaluation of an individual’s hearing involves administering a test battery, and these assessments collectively complement each
other in defining the degree, type, and configuration of hearing loss. Among the acoustic stimuli used in such tests, speech signals are the most
complex and possess significant redundancy. Therefore the use of conventional word lists during routine audiological evaluation may, through
redundant information, lead to overestimation of the performance of individuals with high-frequency sloping hearing loss. The Gujarati language, with 56 million native speakers in India, currently has only a conventional speech identification test. The present study aimed at developing and standardizing high-frequency word lists in Gujarati.Material and MethodsThe study was conducted in three phases. Phase I: development of high-frequency word lists in Gujarati. Phase II: establishment of norms for the developed word lists on 180 normal hearing individuals belonging to different geographic regions of Gujarat. Phase III:
Checking the applicability on 25 individuals with high-frequency sloping hearing loss and 25 individuals with flat frequency hearing loss.ResultsA Shapiro–Wilks test revealed a normal distribution. One-way ANOVA revealed no significant difference between the scores obtained from the two high-frequency word lists. There was a significant difference in mean speech identification scores (SIS) for individuals
with high-frequency sloping hearing loss in which use of conventional word lists gave a mean score of 77% while use of the high-frequency
word lists gave a mean score of 53%.ConclusionsTwo high-frequency word lists each of 25 words were developed. The word lists were found to be reliable, equally difficult,
interchangeable, and effective in detecting communication difficulties due to high-frequency sloping hearing loss.
PARENTING A DEAF CHILD – HOW HEARING PARENTS COPE WITH THE STRESS OF HAVING DEAF CHILDREN
Authors: Kobosko Joanna 
Published: May 2021

BackgroundParents of deaf or hard of hearing (D/HH) children experience greater parenting stress than parents of typically developing children. Studies of the stress experienced by these parents, and their methods of coping with it, give different results depending on the medical intervention used – cochlear implant or hearing aid – and in Poland such studies have not yet been done. This study addresses the ways by which parents handle the stress of adapting to their child’s deafness. It asks whether their styles of coping with stressful situations – task oriented, emotion oriented or avoidance – change after diagnosis is made. Another issue was whether medical intervention, e.g. cochlear implantation in prelingually deaf children, relates to a certain style of coping with stress, and whether the parents’ satisfaction with the decision to implant related to their behavior in stressful situations.Material and MethodsThe research is based on a questionnaire containing demographic information about the parents (age, sex, education), their satisfaction with the decision on cochlear implantation, and information about the child. A Polish version of Coping Inventory for Stressful Situations (CISS) was used.ResultsThe results show that mothers and fathers of D/HH children differ in the intensity of their emotion-oriented and avoidance styles and that in stressful situations mothers use these styles significantly more often than fathers. Parents of D/HH children using cochlear implants do not differ from those using hearing aids in terms of stress coping styles.ConclusionsThese insights offer practical suggestions of ways to psychologically help parents of deaf children, enabling them to cope better with their parenting a deaf child.

Published: May 2021

BackgroundCochlear implant (CI) eligibility criteria have broadened recently to include individuals with partial deafness
(PD). In 2002, the Institute of Physiology and Pathology of Hearing, Poland, pioneered a particular technique of cochlear
implantation termed partial deafness treatment (PDT) and achieved unrivalled rates of functional hearing preservation. Encouraged by the results in adults, a pediatric PDT program was initiated in 2004. The outcome of PDT for both adults and
children has been well documented and assessed with objective measures of sound detection and speech discrimination. The
current study explores outcomes in real life rather than in a clinical setting. We hypothesized that if PDT provides children
with renewed listening ability it is likely to have a major impact on family life and that this impact should be able to be documented by parental reports.Material and MethodSeven parents of PDT cochlear-implanted children were surveyed using 20 open-ended prompts. The
questionnaires were sent to patients’ homes. The parents were asked to answer the prompts in their own words.ResultsAll parents reported that after their child received cochlear implant there was a significant improvement in speech understanding and better perception of high pitched sounds. More than half the parents also noticed positive changes in speech
production. The changes in communication abilities after CI positively influenced the child’s relationships with family members and school mates.ConclusionsThe results of this study support expanding the criteria for receiving a cochlear implant to include children with
partial deafness.
OTOACOUSTIC EMISSIONS FOR EVALUATING THE
LOW-FREQUENCY HEARING OF PATIENTS CONSIDERED
FOR PARTIAL DEAFNESS TREATMENT

Published: May 2021

BackgroundIn the present study otoacoustic emissions (OAEs) were used to evaluate the hearing of partial deafness subjects
who had normal hearing up to 0.5 kHz and severe hearing loss above that frequency. The purpose of the study was to detect
OAEs at 0.5 kHz and determine whether broad-band or band-limited values of OAE parameters were better for distinguishing ears with OAEs from those without.Material and MethodsThe study group consisted of 15 subjects with high-frequency hearing loss above 0.5 kHz. For reference, a group of 15 subjects with severe to profound sensorineural hearing loss over the whole of the 0.125–8 kHz range was
used. In both groups, click-evoked OAEs (CEOAEs) and tone burst-evoked OAEs (TBOAEs) of 1 or 0.5 kHz were evaluated
using a reproducibility parameter, taking into consideration broad-band, octave, and half-octave band values.ResultsIn the study group the best results were obtained by using 0.5 kHz TBOAEs. Clicks and 1 kHz tone bursts generally did not produce a response at 0.5 kHz. TBOAEs at 0.5 kHz enabled the separation of partially deaf ears from ears with severe hearing impairment. Half-octave band filtering yielded the best results; however, it was only slightly better than broadband and octave band filteringConclusionsThe results of the study indicate that the 0.5 kHz TBOAE is a better stimulus than CEOAE and 1 kHz TBOAE
when cochlear function at low frequency needs to be tested. The half-octave band seems the best choice in order to get frequency-specific information. However the results should be treated with caution since the studied groups were relatively small.
CYTOKERATIN 16 EXPRESSION DOES NOT INDICATE
CHOLESTEATOMA AGGRESSIVENESS
Authors: Mostafa Badr , Salah Eldin El-Monayeri Magda , Elfiky Lobna , Mohammed Mohammed , Sarwat Abdel 
Published: May 2021

AimsCholesteatoma is characterised by a squamous epithelium in the middle ear and aggressive destructive behavior. A hyperproliferative epithelium also typically has an overexpression of cytokeratin 16 (CK16). The aim of this study was to compare CK16 expression in cholesteatoma epithelium and the epithelium of simple dry perforations.MethodsSamples were obtained from 60 patients: 30 with cholesteatoma and 30 with simple perforations. The epithelium
was immunohistochemically stained for CK16. Correlations were made between the clinical picture and the absence or presence of complications in both groups.ResultsImmunohistochemical staining for CK16 was positive in 45% of specimens taken from the edge of simple perforations and in 51% of specimens taken from the cholesteatoma matrix. The difference was not statistically significant.ConclusionTwo implications of our findings may be suggested: in cases of cholesteatoma the change in CK expression from
normal epithelium is not the only factor which makes cholesteatoma aggressive; alternatively, in normal tissue the edge of a
simple perforation is not as stable as is thought so that at least 45% of perforations can show hyperproliferative activity. It is
therefore unclear whether hyperproliferative activity in either cholesteatoma or a simple perforation is a marker of instability or of attempts at healing.
RECOMMENDATIONS FOR MONITORING HEARING IN
CHILDREN USING A RISK FACTOR REGISTRY
Authors: Beswick Rachael , Driscoll Carlie , Kei Joseph , Glennon Shirley 
Published: May 2021

BackgroundThe Joint Committee on Infant Hearing (JCIH) of the American Academy of Pediatrics recommends targeted
surveillance of at-risk infants using a risk factor registry, in conjunction with parent and/or professional monitoring to detect hearing loss that develops after newborn hearing screening. However, criticisms of these recommendations are emerging as targeted surveillance programs are costly, resource intensive, have poor follow-up rates, and lack evidence of best practice. The purpose of the current paper is to provide recommendations for risk factor registries incorporated within targeted
surveillance programs.MethodsRecommendations provided in this document were developed by combining the results of previous research, done
with a systematic review of the literature, together with a comprehensive evaluation of a targeted surveillance program in
Queensland, Australia.ResultsRecommendations are as follows. Children with the risk factors of family history or craniofacial anomalies should
have their hearing monitored, whereas children with the risk factor of low birth weight should not. Children with the risk factors of syndrome or prolonged ventilation should potentially have their hearing monitored; however, the evidence is not definitive. Equally, children with bacterial meningitis, hyperbilirubinemia, or professional concern as a risk factor may potentially
not need their hearing monitored, but again the evidence is not definitive. For the risk factors of severe asphyxia and congenital infection, the evidence was inconclusive and/or conflicting, so no recommendations are made.ConclusionsMore research is needed to further inform evidence-based clinical policy recommendations for hearing loss detection in early childhood.
ELECTRIC AND ACOUSTIC DYNAMIC RANGES AND
LOUDNESS GROWTH FUNCTIONS: A WITHIN-SUBJECT
COMPARISON IN COCHLEAR IMPLANT PATIENTS
Authors: Vermeire Katrien , Lawson Dewey 
Published: May 2021

Objectives(1) To estimate the dynamic range (DR) for electric stimulation by means of acoustic and electric loudness matching; (2) to characterize loudness growth as a function of electric stimulus amplitude across the DR.DesignProspective study.Study DesignThree cochlear implant subjects, with normal hearing in the contralateral ear, participated in this study (ME28, ME-29, ME-30). For each electrode, the upper limit of electric stimulation was loudness matched to three different types
of pitch-matched acoustic stimuli. Within the electric DR, the 25%, 50%, and 75% points were loudness matched to the acoustic stimuli to create loudness growth functions.ResultsME-28’s DRs for electric stimulation were constant at 17–18 dB across electrodes. ME-29’s and ME-30’s DRs were
narrower, at around 10 dB. For ME-28 and ME-30, none of the corresponding DRs for matched acoustic stimuli exceeded 50
dB. Only one of ME-29’s DRs exceeded 35 dB. Loudness growth functions showed a tendency for basal electrodes to have gentler overall slopes. For relatively high proportions of the DR, the three different types of acoustic stimuli tend to have similar
loudness growth slopes. However at low levels, the fewer harmonics, the steeper the loudness growth.ConclusionsThere is qualitative and quantitative agreement but patterns of variation can also be observed.

Published: May 2021

BackgroundInformation about the prevalence of communication disorders is essential for planning prevention and rehabilitation services. The aim of this study was to estimate the prevalence of communication disorders between gender and across
age groups among a rural population of India. This work reports a study conducted as part of field work by staff and students
of the All India Institute of Speech and Hearing (AIISH), Manasagangothri, Mysore, India.Material and MethodsA door-to-door survey of 15,441 individuals from 15 villages, irrespective of their age and gender, was
conducted as phase I of the study. The villages were selected on a random basis. A modified high-risk questionnaire was administered to identify individuals at risk of communication disorders. Those found at risk were referred for detailed audiological and/or speech and language evaluation in phase II of the studyResultsThe survey found that the prevalence of individuals at risk of communication disorders was 6.07%. Among those at
risk, and who attended phase II of the study, the prevalence of audiological and/or otological disorder was found to be 90.58%
and that of speech and language disorder was 9.42%. Among those at risk of speech and language disorder, 22.9% were found
to be at risk of mental retardation.ConclusionsAudiological and/or otological disorders were found to be more prevalent among communication disorders
in the selected population. In general, males showed a higher prevalence of communication disorders compared to females.
The prevalence of severe and moderately severe hearing loss was found to be higher than other degrees of hearing loss. Child
language disorders and reading/writing difficulties were the most prevalent problems among speech and language disorders.
MISMATCH NEGATIVITY IN CHILDHOOD TEMPORAL LOBE EPILEPSY: A PROPOSED PARADIGM FOR TESTING CENTRAL AUDITORY PROCESSING
Authors: Tomé David , Moreira Pedro , Marques-Teixeira João , Barbosa Fernando , Jääskeläinen Satu 
Published: May 2021

BackgroundTemporal lobe epilepsy (TLE) is a neurological disorder that directly affects cortical areas responsible for auditory processing. The resulting abnormalities can be assessed using event-related potentials (ERP), which have high temporal resolution. However, little is known about TLE in terms of dysfunction of early sensory memory encoding or possible correlations between EEGs, linguistic deficits, and seizures. Mismatch negativity (MMN) is an ERP component – elicited by introducing a deviant stimulus while the subject is attending to a repetitive behavioural task – which reflects pre-attentive sensory memory function and reflects neuronal auditory discrimination and perceptional accuracy.HypothesisWe propose an MMN protocol for future clinical application and research based on the hypothesis that children with TLE may have abnormal MMN for speech and non-speech stimuli. The MMN can be elicited with a passive auditory oddball paradigm, and the abnormalities might be associated with the location and frequency of epileptic seizures.SignificanceThe suggested protocol might contribute to a better understanding of the neuropsychophysiological basis of MMN. We suggest that in TLE central sound representation may be decreased for speech and non-speech stimuli.DiscussionMMN arises from a difference to speech and non-speech stimuli across electrode sites. TLE in childhood might be a good model for studying topographic and functional auditory processing and its neurodevelopment, pointing to MMN as a possible clinical tool for prognosis, evaluation, follow-up, and rehabilitation for TLE.

Published: May 2021

BackgroundCandidacy for cochlear implantation has been expanding in recent times to include individuals with low-frequency residual hearing who do not benefit from conventional hearing amplification. Recent cochlear implant electrode arrays provide maximal preservation of residual hearing when introduced using a ‘soft insertion’ technique. This study analyzes
the efficacy of soft insertion and the outcomes of such implantation in candidates with residual hearing.Material and MethodsOur prospective, non-randomized study, chronologically documented: (A) the efficacy of the hearing preservation technique in cochlear implantees with residual hearing by soft insertion technique (round window or cochleostomy), and (B) the auditory verbal outcomes in 10 cochlear implantees with residual hearing (Group A) compared with
a control group of 10 age-matched post-lingual candidates with profound hearing loss (Group B), as measured by Categories of Auditory Performance, Speech Intelligibility Rating, Cochlear Implant Aided Audiometry, and Hearing In Noise Test.ResultsThe results suggest that soft insertion via cochleostomy or round window were effective in preserving residual hearing.
In the 6-month post-operative audiogram, 60% of our implantees had complete preservation and 40% had moderate preservation. Our study also underlines the beneficial effects of residual hearing: (a) hearing in noise test with mean average for Group
A (59%) and Group B (45%) with p value=0.007, (b) 6-month post-operative CI aided frequency specific comparison between
the groups showed p values of 0.001, 0.039, and 0.34 at 250, 500, and 1000 Hz respectively. However, on auditory verbal scores
(CAP and SIR scores), Group A implantees performed better on clinical analysis, although there was no statistical significance.ConclusionsThe hearing preservation technique has heralded the arrival of next generation cochlear implants which provide a hearing solution for candidates with low-frequency residual hearing who do not benefit from conventional hearing aids.
Our study shows that there is significant advantage obtained in auditory verbal habilitation outcomes and hearing in noise
perception using soft surgery techniques which maintain the microstructure of the spiral ganglion and osseous spiral lamina.

Published: May 2021

BackgroundThe aim of this prospective study was to examine the link between Meniere’s disease and migrainous vertigo and
assess the value of common non-invasive otoneurologic tests in the differential diagnosis.Material and MethodsA total of 38 patients with definite Meniere’s disease (MD), 24 with non Meniere’s vertigo, dizziness
or unsteadiness (control group), and 10 patients with definite Vestibular Migraine (VM) underwent a full otoneurological
screening which included an audiometric examination, extratympanic electrocochleography (ET – ECochG), cervical vestibular evoked myogenic potentials (cVEMPs) and videonystagmography with bithermal stimulation.ResultsNone VM patient presented with abnormal ECochG finding, in contrary to 61% of MD patients, and 4% in the control group. The difference was statistically significant (p<0.001). Pathological cVEMP results and unilateral weakness in caloric stimulation were found in 30% and 10% in VM population, whereas in 52.6% and 55.3% in MD. Again, the difference was
statistically significant (p<0.001).ConclusionsThe results indicate that certain vestibular test – as ECochG – could often help in the differentiation between
VM and MD patients, especially in atypical cases. Last but not least, it seems that both diseases have a common electrophysiological background according to the similar cVEMP pathological findings.
Prevalence of cochlear implants in Europe:
What do we know and what can we expect?
Authors: De Raeve Leo , van Hardeveld Ruud 
Published: May 2021

BackgroundCochlear implantation is the major beneficial treatment of bilateral profound deafness in children and adults,
but there are big differences in utilisation between European countries.Material and MethodStatistical data on the number of implanted persons are obtained each year by Euro-CIU (the European Association of Cochlear Implant Users). This study models the trends and gives an overview of the current number of cochlear implants in 16 European countries; our model predicts the future demand on cochlear implants in children and adults.ResultsThe degree of utilisation of cochlear implantation by suitable children and adults varies considerably between the
European countries. Most less affluent East European countries focus on the implantation of children rather than adults. Although adult recipient numbers are growing, it has been estimated that less than 10% of adult candidates in Europe receive a
CI. There is little to no scientific data available on late onset, or progressive, hearing loss in children or adults.ConclusionIt is possible to estimate the yearly number of CI candidates in a country, but we don’t yet have enough reliable
data to put into our model. Because of the underutilisation of cochlear implants, especially in adults, we have to work on raising the general awareness of the benefits of cochlear implants, and its improvement in quality of life, based on cost-effectiveness data and on guidelines for good clinical practice.
