Abstract
Hypoparathyroidism, deafness, and renal dysplasia (HDR) syndrome is an autosomal dominant disorder. Because HDR syndrome is caused by haploinsufficiency in GATA3, it exhibits variation in the onset and progression of hearing loss. In previous reports, the automated auditory brainstem response (AABR) was considered insufficient to detect sensorineural hearing loss caused by HDR syndrome. We report a case of HDR syndrome whose congenital hearing loss was detected by newborn hearing screening (NHS) using AABR. In this case, HDR syndrome was suspected due to hearing loss, hypocalcemia, and her family history. Genetic testing confirmed the diagnosis of HDR syndrome at 5 months of age. Because the phenotype of hearing loss due to HDR syndrome is variable and includes progressive hearing loss, these cases may not be detected by the HNS. However, most of the previous reports were published before the NHS became common and given the frequency of hearing loss complications in HDR syndrome. We consider that there is a reasonable number of HDR syndrome cases with abnormalities on the NHS. We believe that the NHS may also be useful for early detection of hearing loss due to HDR syndrome.

Abstract
OBJECTIVES Hearing loss (HL) constitutes an increasing worldwide health problem. Neonatal hearing screening improved early detection and management to alleviate HL detriments on the person and society. Still, HL in childhood, beyond infancy, is under-investigated, especially in developing countries. This study aimed to explore the prevalence of HL in childhood amongst Jordanian children with HL risk factors and investigate the associated risk factors. METHODS Retrospective cross-sectional review of audiological records in a tertiary public and teaching hospital. The data of 1307 children aged 0-15 years who underwent audiological assessment from 2000 to 2016 were included. A review of diagnostic audiological and medical records was conducted to investigate the prevalence of sensorineural HL in high-risk (HR) children and the most contributing risk factors. RESULTS Descriptive statistical analysis showed that the prevalence of sensorineural HL was 29.2% in the study sample. The HL was bilateral in 95% and mild to moderate HL in 73%. The mean age at the diagnosis was around 4.5 years. The most common risk factors were parental concern about their child's hearing, ototoxic drug use, and developmental and speech delay. The Chi-squared test showed that parental concern and ototoxic drug use were associated with an increased probability of having HL. CONCLUSION The prevalence of HL amongst at-risk children in Jordan is relatively high, and the diagnosis is delayed. The results highlight the importance of implementing a hearing screening program in at-risk children. This needs to start from birth and include a serial follow-up to detect cases of delayed-onset HL.

Abstract
INTRODUCTION In newborns, hearing loss secondary to congenital Cytomegalovirus (CMVc) infection, despite its low prevalence, can cause a serious problem in the personal development and social integration of patients. Therefore, it is important to include the determination of CMV DNA as a neonatal screening tool. MATERIALS AND METHODS We have carried out a 5-year retrospective study, by describing the CMVc in the Autonomous Community of the Basque Country in newborns who did not pass the hearing screening in the early hearing loss detection program. The times of detection, confirmation (incidence) and intervention (treatment) are described. RESULTS Of 18,782 subjects studied, 58 (three per thousand live births) presented hearing loss. Of these, CMVc is guaranteed in four patients (one woman and three men). The mean time to hearing screening was 6.5 days (SD: ±3.69) and to detect CMV by polymerase chain reaction (PCR) in urine and saliva was 4.2 days (SD: ± 3.94). Time to confirm hearing loss by BAEP and audiological intervention 2.2 (SD: ±0.957) and 5 months (SD: ±3.741), respectively. Four hearing aid adaptations and one cochlear implant were performed. DISCUSSION AND CONCLUSION Neonatal hearing screening has established itself as a good public health program. The determination of viral DNA allows an early, specific and interdisciplinary diagnosis and treatment, in which otorhinolaryngology plays a fundamental role. Our study highlights the importance of including CMV PCR as a universal screening tool.

Abstract
OBJECTIVE To study and analyse the result obtained in cochlear implantation by Veria technique and evaluate the incidence of surgical complications and their management. METHOD Between Jan 1, 2014 to Jan 1, 2019, 602 cochlear implantations by Veria technique were done out of which 576 patients were analysed retrospectively for the study. The age range was between 18 months and 60 years. RESULT All 576 patients were operated by Veria technique. Out of 576 patients, 57 (9.9%) had abnormal cochlear malformation. Cytomegalovirus (CMV) being the most common non genetic cause of congenital hearing loss accounting to 60%. The overall complication rate of 5.5% was observed in 576 implanted patients. CONCLUSION The analysis of the results shows that this method has certain advantages, which are: it is simple and therefore the learning curve is fast; it is safe for the facial nerve, as the drilling is precisely controlled by the special perforator; it produces minimal bone trauma and due fast healing, it permits early fitting a few days after operation; it can be used for very small children where the mastoid may have not been yet sufficiently developed.

Abstract
Hearing loss is considered the most common birth defect. The estimated prevalence of moderate and severe hearing loss in a normal newborn is 0.1%-0.3%, while the prevalence is 2%-4% in newborns admitted to the newborn intensive care unit. Neonatal hearing loss can be congenital (syndromic or non-syndromic) or acquired such as ototoxicity. In addition, the types of hearing loss can be conductive, sensorineural, or mixed. Hearing is vital for the acquisition of language and learning. Therefore, early detection and prompt treatment are of utmost importance in preventing the unwanted sequel of hearing loss. The hearing screening program is mandatory in many nations, especially for high-risk newborns. An automated auditory brainstem response test is used as a screening tool in newborns admitted to the newborn intensive care unit. Moreover, genetic testing and screening for cytomegalovirus in newborns are essential in identifying the cause of hearing loss, particularly, mild and delayed onset types of hearing loss. We aimed to update the knowledge on the various aspects of hearing loss in newborns with regard to the epidemiology, risk factors, causes, screening program, investigations, and different modalities of treatment.

Abstract
Congenital hearing loss is hearing loss present in a child at birth or soon after birth. It is a debilitating condition with the potential for lifelong disability. It is thought to be multifactorial in aetiology with both genetic (autosomal and X-linked) and acquired causes (such as maternal infections, drug intake, trauma). Gestational Diabetes Mellitus (GDM) is a relatively common condition found in pregnant females but is a rather understudied risk factor in terms of congenital hearing loss. GDM is easily treatable which makes the hearing loss due to it easily preventable. (1) Determine correlation between Gestational Diabetes Mellitus and congenital hearing loss in neonates. (2) Calculate the prevalence of Gestational Diabetes Mellitus related congenital hearing loss. A two-step screening process was used for hearing evaluation of neonates with normal mothers (non-exposed) and neonates with mothers suffering from GDM (exposed) through Otoacoustic emission (OAE) and Brainstem Evoked Response Audiometry (BERA). (1) The difference of neonates diagnosed with hearing impairment in exposed and non-exposed group was statistically significant with a p-value of 0.024. OR 2.1538 95% CI 0.6120-7.5796, p < 0.05. (2) Prevalence of hearing loss in neonates of GDM mothers: 13.3%. Through rigorous exclusion of the already known risk factors for congenital hearing loss, Gestational Diabetes Mellitus has been isolated as an independent risk factor for neonatal hearing impairment. We hope to identify additional cases of congenital hearing loss early leading to a decrease in disease burden.

Abstract
SARS-CoV-2, the responsible virus for the COVID-19 pandemic, has demonstrated neurotropic properties indicated by cases presenting with auditory and vestibular system insults. The expression of ACE-2 receptors in the placenta and the detection of IgM antibodies against the virus in the fetuses of pregnant women suffering from COVID-19 render vertical transmission of the infection to the fetus possible. Thus, our study aims to examine whether, similar to other viruses like CMV, SARS-CoV-2 is responsible for congenital hearing loss. This is a retrospective study in a regional pediatric hospital. The medical records of newborns (n = 111) born by mothers positive for COVID-19 during pregnancy who underwent screening hearing tests with Transient Evoked Otoacoustic Emissions (TEOAE) and Automatic Auditory Brainstem Response (AABR) from February 2020 to June 2022 were reviewed. Neonates with additional aggravating factors for congenital hearing loss were excluded from the study. For the study period, nine mothers were found positive during the first trimester, twenty mothers in the second trimester, and eighty-three mothers in the third trimester. TEOAEs test and AABR test scored PASS bilaterally in all neonates tested. CONCLUSION Infection with COVID-19 during pregnancy was not a risk factor for hearing loss, similar to other studies. WHAT IS KNOWN • The pathogenetic mechanism of the viral-induced impairment of the organ of Corti includes direct damage to the hair cells and indirect damage due to the induction of the innate inflammatory response. • Early data suggested that the SARS-CoV-2 virus also has neurotropic properties with manifestations from the sensory epithelia. WHAT IS NEW • Although the intrauterine infection remains controversial, the expression of the ACE-2 receptor on the placenta and the detection of IgM antibodies, as well as the covid-19 genome in fetuses, make the vertical transmission tenable. • In our study, the newborn hearing screening results indicate that COVID-19 infection during pregnancy is not a risk factor for hearing loss.

Abstract
PURPOSE The study aims to assess the benefit of sequential bilateral cochlear implantation in children with congenital bilateral profound hearing loss, submitted to the first implant at an early age. METHODS We enrolled all the bilateral sequential cochlear implanted children who received the first implant within 48 months and the second within 12 years of age at our Institution. The children were submitted to disyllabic word recognition tests and Speech Reception Threshold (SRT) assessment using the OLSA matrix sentence test with the first implanted device (CI1), with the second implanted device (CI2), and with both devices (CIbil). Furthermore, we measured the datalogging of both devices. Then we calculated the binaural SRT gain (b-SRTgain) and checked the correlations between speech perception results and the b-SRTgain with the child's age at CI1 and CI2, DELTA and the datalogging reports. RESULTS With the bilateral electric stimulation, we found a significant improvement in disyllabic word recognition scores and in SRT. Moreover, the datalogging showed no significant differences in the time of use of CI1 and CI2. We found significant negative correlations between speech perception abilities with CI2 and age at CI2 and DELTA, and between the SRT with CI1 and the b-SRTgain. CONCLUSIONS From this study we can conclude that in a sequential CI procedure, even if a short inter-implant delay and lower ages at the second surgery can lead to better speech perception with CI2, children can benefit from bilateral stimulation independently of age at the second surgery and the DELTA.

Abstract
Background Hearing loss is one of the most common congenital disorders. The Early Diagnosis and Intervention Process is designed for the early diagnosis and intervention of hearing loss in infants. The present study aimed to examine the results of Early Hearing Detection and Intervention (EHDI) in northeastern Iran from 2005 to 2019. Setting Northeastern Iran. Methods In most cases, the two-stage protocol (otoacoustic emissions [OAE] and automated auditory brainstem response [AABR]) has been used. Infant assessment methods included the use of OAE, ABR, auditory steady-state response, high-frequency tympanometry, and behavioral audiometry. Interventions included medical interventions, hearing rehabilitation, hearing aids, and cochlear implants. Results 1,162,821 infants were screened. The screening coverage increased from less than 1% in 2005 to about 99% in 2018. The referral rate has been about 1%. 2.17 out of every 1000 infants are hearing impaired, and the most common cases are bilateral hearing loss and mild to moderate hearing loss. Conclusions During 2005 to 2019 the coverage rate reached to more than 95% of live births. To improve the EHDI process in this population, better follow-up of diagnosed neonates and expansion of diagnostic and intervention services are needed.

Abstract
INTRODUCTION National recommendations in the United States specify that all infants with hearing impairment should be identified by 3 months of age. Infants who fail universal newborn hearing screening (UNHS) require follow up testing after hospital discharge. Follow up testing may be difficult to obtain in some communities within the ideal time frame. A rapid access multidisciplinary clinic was established for failed UNHS. The objective of this study is to report outcomes and patient satisfaction from an early access hearing detection clinic. METHODS Infants that failed UNHS were seen in the multidisciplinary clinic between 1/1/19 and 2/28/22. Patients underwent automated auditory brainstem response (ABR) and distortion product otoacoustic emissions testing and consulted with an otolaryngology nurse practitioner. Failed results were followed by diagnostic ABR. Surveys were administered at the beginning and end of the appointment. RESULTS In total, 169 infants were seen at a mean age of 8.4 weeks (95%CI 7.5, 9.4). Repeat testing was abnormal in 38 (22.4%). Diagnostic ABR was performed at an average age of 13.7 weeks (n = 34, 95% CI: 10.8, 16.6) and led to a diagnosis of hearing loss in 18 infants. Twenty-seven parents completed surveys at the initial visit. Anxiety level among patients with normal repeat testing (n = 20) decreased from 1.9 to 1.2 (p = .002), while anxiety level among those with abnormal repeat testing (n = 7) was not statistically different before and after (2.1 vs 2.7, p = .2). Satisfaction level was 3.7 ± 0.7 (scored 1-4). All parents reported having a better understanding of their child's hearing problem after the visit. DISCUSSION This novel nurse practitioner-led early hearing detection clinic enabled timely diagnosis of hearing loss and reassurance to families without hearing loss. Age at hearing loss diagnosis compares favorably to published cohorts.

Abstract
OBJECTIVES To investigate factors associated with time of diagnosis and habilitation of congenital hearing loss in Indonesia. METHOD A retrospective cohort study was conducted from January to December 2020 by collecting data on patients with congenital hearing loss using validated questionnaires. RESULT Among 535 children with congenital hearing loss, 2.7% had a family history of congenital hearing loss, 11.2% and 37.4% had a maternal history of ototoxic drugs and herbal medicine use during pregnancy, respectively, and 17.8% had prenatal exposure to TORCH infection. Lower maternal education level was shown to be associated with older age at diagnosis (p = 0.045), while older maternal age (p < 0.001), non-housewife mothers (p = 0.029), and out-of-pocket payment scheme (p = 0.027) were associated with a higher rate of habilitation. CONCLUSION The present study showed that the presence of family history, the use of certain medications during pregnancy, and prenatal TORCH infection are prevalent in children with congenital hearing loss in Indonesia. Several factors such as maternal education level, age, occupation, and habilitation payment scheme may be associated with time of diagnosis and habilitation of congenital hearing loss.

Abstract
Congenital sensorineural hearing loss is highly prevalent in our population, with a wide variety of causes. The key to clinical management is early detection and intervention, to promote language and cognitive development. With expanding genetic knowledge about congenital sensorineural hearing loss, the indiscriminate approach in workup is no longer recommended. Comprehensive genetic evaluation and cytomegalovirus testing are key to identify the underlying cause of the hearing loss. Treatment and prognosis depend on age of hearing loss onset and detection; management plans will typically include audiology consultation, speech therapy, and various hearing amplification devices and technologies when applicable.

Abstract
PURPOSE In 2015 a new regulation and guidelines for the universal newborn hearing screening by AABR measurement have been implemented in Hungary. The aim of our study was to analyse (1) the past 5 years of data from our diagnostic centre about the incidence and types of congenital hearing losses, and (2) the first experiences with the National Newborn Hearing Screening Registry, started in 2019, and (3) the influence of the screening on the pediatric cochlear implant program. METHODS 1269 children referred to our diagnostic centre between 2017 and 2021 were investigated. A third AABR measurement and full audiological evaluation were performed. Furthermore, one-year period data of the screening registry, and the number of implanted children at or under the age of 3 were analysed using the national databases. RESULTS Altogether 276 newborns (22% of the referred cases after the two-stage screening) had hearing loss, 134 (49%) out of them was conductive origin, almost twice frequent in male as in female. Permanent sensorineural hearing impairment was found in 142 (51%), 58 (40%) of them had bilateral, severe to profound hearing loss, occurring more frequently in male as in female. The national digital registration of the screening data within 12 months concerned 68%. The number of early cochlear implantation in one year increased from 1 to 23 children in the past 15 years. CONCLUSION A third AABR after the two-stage screening increased the efficiency and filtered the 78% false-positive cases. The audiological diagnostics verified and typed the hearing losses ensuring the early intervention.

Abstract
BACKGROUND Stapedial tendon ossification is a rare disease, with only a few reports. The stapedial tendon originates from the apex of the pyramidal eminence and is attached to the neck of the stapes. In stapedial tendon ossification, the stapes is fixed, causing conductive hearing loss. In most cases, complete hearing restoration is achieved by dividing the stapedial tendon after exploratory tympanotomy.
CASE SUMMARY A 28-year-old woman presented to our hospital with the major complaint of bilateral hearing loss that started during childhood. Exploratory tympanotomy was performed due to suspicion of otosclerosis or middle ear anomalies. We found bilateral conductive hearing loss due to stapedial tendon ossification with a middle ear anomaly during surgery. There have been several reports of complete recovery of hearing after resection of the stapedial tendon. However, in this case, recovery of hearing was insufficient, even with the division of the stapedial tendon. In the second surgery, the stapes anomaly and footplate fixation were confirmed, and hearing was completely recovered after stapedotomy. Therefore, we report this case with a review of the relevant literature.
CONCLUSION This is the first case of stapedial tendon ossification and fixation of the footplate surgically diagnosed on both sides. With surgical treatment, successful results are expected.

Abstract
INTRODUCTION There are particular challenges in the implantation of malformed cochleae, such as in cases of facial nerve anomalies, cerebrospinal fluid (CSF) leaks, erroneous electrode insertion, or facial stimulation, and the outcomes may differ depending on the severity of the malformation. The aim of this study was to assess the impact of inner ear malformations (IEMs) on surgical complications and outcomes of cochlear implantation. METHODS In order to assess the impact of IEMs on cochlear implant (CI) outcomes, 2 groups of patients with similar epidemiological parameters were selected from among 863 patients. Both the study group (patients with an IEM) and control group (patients with a normal inner ear) included 25 patients who received a CI and completed at least 1 year of follow-up. Auditory performance, receptive and expressive language skills, and production and use of speech were evaluated preoperatively and at least 1 year after implantation. Types of surgical complications and rates of revision surgeries were determined in each group. RESULTS In the study group, the most common malformation was an isolated enlarged vestibular aqueduct (EVA) (44.8%). Overall, the patients with IEMs showed significant improvement in auditory-verbal skills. In general, the patients who had normal cochleae scored significantly better compared to patients with IEMs (p < 0.05). The complication rate was significantly lower in the control group compared to the study group (p = 0.001), but the rate of revision surgeries did not differ significantly (p = 0.637). CONCLUSION It is possible to improve communication skills with CIs in patients with IEMs despite the variations in postoperative performances. Patients with EVA, incomplete partition type 2, and cochlear hypoplasia type 2 were the best performers in terms of auditory-verbal skills. Patients with IEMs scored poorly compared to patients with normal cochleae. CSF leak (gusher or oozing) was the most common complication during surgery, which is highly likely in cases of incomplete partition type 3.

Abstract
Hereditary hearing loss accounts for nearly 60% of deafness in developed countries and about 30% of them are syndromic. Pierre Robin Syndrome is one such condition. The patient with this syndrome usually presnts with triad of micrognathia, glossoptosis and cleft palate. Hearing loss is mostly conductive but there can be sensorineural hearing loss also. Here we present a case of Pierre Robin Syndrome who presented with congenital hearing loss. He also had bilateral serous otitis media. He underwent cochlear implant surgery and was prescribed antihistaminics and steroid spray for middle ear effusion. Therefore, proper clinical evaluation is required.

Abstract
Background Salivary gland choristoma (SGCh) is a rare benign tumor reported in several unusual sites, such as the gastrointestinal tract, the optic nerve, and the internal auditory canal, but never reported in the inner ear. Case presentation An 8-year-old girl with a history of left profound congenital hearing loss presented to us with ipsilateral progressive severe facial nerve palsy (House-Brackmann Grade VI). The left tympanic membrane was swollen with a pulsatile tumor. Radiological investigations revealed a multilocular tumor in the inner ear extending into the middle ear and internal auditory canal (IAC). We performed a partial resection of the tumor by transmastoid approach to preserve the anatomical structure of the facial nerve. The tumor was pathologically diagnosed as SGCh. Two years after surgery, her facial function recovered to House-Brackmann Grade II and the residual tumor did not show regrowth on MRI. Conclusions Although the natural course of this rare tumor is unknown, a partial resection is an acceptable treatment procedure when functional recovery of the facial nerve is anticipated.

Abstract
OBJECTIVE: The aim of the study was to evaluate the results of neonatal hearing screening in our hospital with the help of literature and to question and reveal the risk factors to gain healthy individuals and to raise awareness for all health workers and the public who are interested in this subject. METHODS: A total of 16,388 newborn infants were evaluated between October 2009 and January 2018. All newborns were screened with transient evoked otoacoustic emissions (TEOAEs) test. Risk factors were investigated. The test repetition and auditory brainstem response (ABR) measurements were performed on newborns who could not pass the TEOAE test and the newborns in the risky group after 15 days. RESULTS: A total of 116 newborns (0.7%) were suspected to have hearing loss. Twenty-seven newborns (0.16%) were found to be in intensive care unit. Twelve newborns (0.07%) had permanent hearing loss. Then, in order: 9 newborns (0.05%) had received phototherapy and 7 newborns (0.04%) were born to consanguineous marriages. In addition, 3 newborns (0.02%) had a low birth weight and 1 newborn (0.006%) had a history of fever. CONCLUSION: Screening tests should be performed in all newborns for early detection of hearing loss. Even though frequency of hearing loss is higher in newborns with risk factors, the treatment should be started within 6 months, the latest, and newborns should be referred for rehabilitation and training.

Abstract
OBJECTIVE A review of published data regarding binaural hearing after treatment of congenital unilateral conductive hearing loss (UCHL) due to aural atresia. Treatment options concern atresia surgery (reconstructive surgery), application of a bone conduction device (BCD), or application of a middle ear implant (MEI). DATA SOURCES Database PubMed was searched for articles published in English and German between January 1, 1994, and January 1, 2019. STUDY SELECTION The initial search identified 52 studies, of which 9 met the inclusion criteria. DATA SYNTHESIS Comparison of studies was based on a structured review. Meta-analysis was not feasible because of the heterogeneity of outcome measures, the limited number of relevant papers (9), and diverse types of treatment (5). CONCLUSIONS Treatment of UCHL results in bilateral hearing instead of binaural hearing. The large intersubject variability in benefit of treatment is unexplained with a clear improvement in the minority of listeners and a limited improvement or binaural interference in most listeners after atresia repair or amplification with a BCD or MEI.

Abstract
Since January 2012, babies born in the province of Modena, Italy, have routinely undergone hearing testing as part of a two-stage screening programme. Newborn hearing screening (NHS) has been based on an integrated hospital and community care system and this study aims to assess screening coverage, referral rates, the prevalence, type and extent of hearing loss several years into the programme. Data were collected from January 1, 2012 to December 31, 2015. Coverage was over 99% in all five facilities of the province. The ratio of "fails of the screening" to the total number of infants tested varied over the period from 1.2% to 0.9% in the third level facility, and from 0.8% to 0.4% in the other four. Although hearing loss was mainly associated with dysmorphic\syndromic diseases or a family history of hearing loss, some 23% of cases were identified with no known risk factors. We highlight the importance of the NHSP and the need for strong support from healthcare administrators to ensure high coverage. This is especially true since although the prevalence of hearing loss was higher among infants with audiological risk factors, several cases of hearing loss were found in newborns with no known risk factors.

Abstract
UNLABELLED Congenital sensorineural hearing loss is related to mutations in numerous genes encoding the structures of the inner ear in majority of the cases. Mutations in GJB2 gene are the most frequently identified causes of congenital nonsyndromal hearing loss. GJB2 gene testing became a routine clinical tool. For GJB2-negative patients new genetic approaches including methods based on new generation sequencing give a chance to identify mutations in other genes. The frequent reason of mild-to-moderate hearing loss such as the deletions/mutations of the gene STRC encoding stereocilin protein were recognized (OMIM: 606440). OBJECTIVES To evaluate the audiological features in hearing impaired patients with deletions and point mutations in the STRC gene. PATIENTS AND METHODS The group of 28 patients from 21 unrelated families with pathological mutations in the STRC gene underwent audiological examination. The description and analysis of the results of full audiological examination was provided. RESULTS All patients initially had bilateral nonsyndromal sensorineural hearing loss. Among 11 homozygotes of large deletion harboring STRC to CATSPER2 genes were 7 male individuals indicating the presence of male infertility syndrome. In general, 7 children failed audiological screening and 4 children underwent audiological assessment in the age of 3 and 6 months. The most frequently hearing thresholds were registered between 35 and 55 dB that corresponds to mild-to-moderate hearing impairment. The average age of diagnostics was 7.9 years (ranged from 3 months to 45 years). In the majority of patients the audiological profiles were flat or descending with elevation of thresholds at middle and high frequencies and relatively preserved thresholds at low frequencies. Hearing thresholds are symmetric and stable with age. CONCLUSION STRC-linked hearing loss is congenital, of mild and moderate severity. Special clinical and genetic approach for children who failed newborn hearing screening with mild-to-moderate hearing loss is necessary.

Abstract
PURPOSE The current loss to follow-up rate after failed newborn hearing screening (NBHS) is 34.4%. Previous studies have found that lack of parental and primary care provider (PCP) awareness of NBHS results are significant contributors to loss to follow-up. The objective of this study was to identify factors associated with parental and PCP awareness of NBHS results. MATERIALS AND METHODS Retrospective cohort study. A survey asking about demographics and knowledge of NBHS testing and results was offered to parents in the waiting room of an urban pediatric primary care office. Included were biological parents ≥18 years of age of children ≤10 years of age born in Pennsylvania. Each child's chart was reviewed for PCP documentation of NBHS results. The odds of knowing NBHS results were evaluated using logistic regression. RESULTS The survey was completed by 304 parents. 74.0% were aware of their child's NBHS results. Child age ≥1 year old (OR: 0.49, 95%CI[0.29, 0.82], P = 0.007) and Hispanic ethnicity (OR: 0.38, 95%CI[0.16, 0.89], P = 0.03) were associated with decreased odds of a parent knowing NBHS results. In addition, fewer fathers knew the results of their child's NBHS compared with mothers (OR: 0.33, 95%CI[0.18, 0.62], P < 0.001). However, parental awareness was not associated with birthing facility or insurance type. 222 charts were reviewed for NBHS documentation, revealing PCP awareness in 95.5% of cases and no associations with any of the factors examined. CONCLUSIONS Factors associated with parents not knowing NBHS results included being the parent of an older child, Hispanic, or the father.

Abstract
OBJECTIVES Newborn hearing screening (NHS) has been actively performed since 2001 in Akita, Japan. The NHS coverage rate has increased yearly, and performance has been consistently >90% since 2012. The purpose of this study was to summarize NHS outcomes in the Akita prefecture of Japan and to obtain new insights for from our summarized data for the future. METHODS A total of 35,461 newborns in hospitals and clinics where hearing screening was performed in Akita from 2012 to 2016 were included. The outcome data of NHS were collected for analysis. RESULTS The overall screening coverage rate for hearing loss was 94.7%. Of the screened infants, 0.53% received a referral on the 2-stage automated auditory brainstem response (ABR), and 80.4% of referred infants had a check-up at the hospital to receive a diagnostic hearing examination. Finally, the prevalence of bilateral congenital hearing loss was 0.14%, that of bilateral moderate to profound hearing loss was 0.12%, and that of unilateral congenital hearing loss was 0.10%. Furthermore, the average consultation period in infants with risk factors was significantly later than that in infants without risk factors (p = 0.0015). Follow-up for infants diagnosed with normal hearing after diagnostic hearing examination revealed that 4.7% suffered bilateral moderate to profound hearing loss later. This percentage is significantly higher than that of the general group (p < 0.001). CONCLUSION The prevalence of bilateral congenital hearing loss was 0.14% in Akita and 0.12% of infants were diagnosed with bilateral moderate to severe hearing loss. Medical personnel should be enlightened regarding the importance of performing hearing diagnostic examinations until 3 months of age. Even if infants were diagnosed with normal hearing after a diagnostic examination, we strongly suggest continuing follow-up until they are able to perform pure tone audiometry with accuracy.

Abstract
PURPOSE Despite the advances made in cochlear implantation techniques, the associated complication rates are still high. Here, we aimed to analyze cases, with extensive follow-up data, associated with a large sample of patients to identify complications related to cochlear implants and to present our surgical experience and the technique that we used in order to follow surgical rules/medical purpose to avoid any complications. METHODS We retrospectively examined cases involving 2597 patients (1342 males; 1255 females; age 1-88 years) who underwent cochlear implantation procedures between November 1995 and July 2019, and we classified complications as minor and major. RESULTS The mean age at the time of implantation was 6.48 (Min: 1/Max: 88) years. The cause of deafness was congenital in 76.5% of the patients and acquired in 16.8%. The overall rate of complications in the study was 3.7% (n = 97). The minor and major complication rates were 3.0 and 0.7, respectively. Further, while the most common minor complication we encountered was vertigo, the most common major complication was implant extrusion. CONCLUSION Fixing the cochlear implant receiver-stimulator with the bone-recess technique and sealing the posterior tympanotomy site with a piece of muscle in order to follow surgical rules/medical purpose to avoid any complications. Following the insertion of the electrode into the cochlea, the muscle closure of the cochleostomy site or the round window restores the original anatomy and in order to follow surgical rules/medical purpose to avoid any complications. We have developed this highly effective technique with years of experience and have not had a major surgical complication in 5 years.

Abstract
PURPOSE Hearing performance data was collected from a large heterogeneous group of subjects implanted with the Cochlear™ Nucleus® CI532 with Slim Modiolar Electrode, for the purposes of postmarket clinical follow-up. Data was analysed for factors which may predict postoperative speech recognition scores. METHODS Data was collected retrospectively from five German clinics for 159 subjects from March 2017 to August 2018. Hearing thresholds and recognition scores for monosyllabic words in quiet and sentences in noise were measured preoperatively and at 3 and 6 months postoperatively. RESULTS There was a mean gain of 44% points (95% CI 39-49%) at 6 months in monosyllable scores in quiet for implanted ears. Preoperative hearing thresholds in implant ears increased systematically with decreasing age; however, younger subjects had better baseline monosyllable scores with hearing aids compared with older subjects. Baseline performance alone explained 14% of the variation in postoperative scores. Residual hearing was preserved on average to within 22 dB at 250 Hz and 30 dB at 500 Hz of preoperative levels. CONCLUSIONS In a large and varied cohort of routinely treated hearing-impaired adults, speech recognition with the CI532 for German monosyllabic words in quiet at 6 months was equivalent to performance reported at one year or more in other published studies. Although younger subjects had poorer preoperative pure-tone thresholds, they had better preoperative word recognition scores compared with older subjects, and also had higher post implant scores. Further research is required to identify if this phenomenon is just applicable to German health system assessment and referral practices.

Abstract
OBJECTIVE To describe the association, or non-association, of public health district staffing (specifically, Early Hearing Detection and Intervention [EHDI] coordinator/navigator) and loss to follow-up in newborns who did not pass hearing screening in selected public health districts in Georgia, USA. METHODS By Freedom of Information request, data regarding newborn hearing screening and loss to follow-up for diagnostic testing and staffing were acquired for three districts in Georgia for six years. The districts were chosen because their coordinator/navigator positions were unfilled at times. RESULTS Lapses in staffing of the district EHDI coordinator/navigator position aligned temporally with decreased follow-up. Aggregate three district data showed that follow-up rates in quarter-years with a fulltime navigator were higher than quarter-years without a full-time navigator (p < .001). CONCLUSION Lapses in staffing dedicated to EHDI navigation-coordination correlated with poorer follow-up after not passing newborn hearing screening.

Abstract
BACKGROUND Hearing loss (HL) represents the most common congenital sensory impairment with an incidence of 1-5 per 1000 live births. Non-syndromic hearing loss (NSHL) is an isolated finding that is not part of any other disorder accounting for 70% of all genetic hearing loss cases. METHODS In the current study, we reported a polygenic mode of inheritance in an NSHL consanguineous family using exome sequencing technology and we evaluated the possible effect of the detected single nucleotide variants (SNVs) using in silico methods. RESULTS Two bi-allelic SNVs were detected in the affected patients; a MYO15A (. p.V485A) variant, and a novel MITF (p.P338L) variant. Along with these homozygous mutations, we detected two heterozygous variants in well described hearing loss genes (MYO7A and MYH14). The novel MITF p. Pro338Leu missense mutation was predicted to change the protein structure and function. CONCLUSION A novel MITF mutation along with a previously described MYO15A mutation segregate with an autosomal recessive non-syndromic HL case with a post-lingual onset. The findings highlight the importance of carrying whole exome sequencing for a comprehensive assessment of HL genetic heterogeneity.

Abstract
The aim of this study was to collect and interpret narrative and observational data from Audiologists and ENT doctors' experiences of delays in the identification and management of congenital hearing loss (CHL) in Libya. This qualitative study sought to explore and understand the reasons behind the delay. Participants were three Audiological Physicians and five Otolarngologists (ENT) working in public hospitals in four large cities in Libya. They were interviewed to explore the causes of such delays and themes were generated from their experiences. All participants revealed that the main causes might be associated with limited facilities and availability of audiology services, lack of awareness and knowledge of the magnitude of the issue and the importance of early detection and intervention for CHL in Libya. In contrast to other developing countries, the financial situation and poverty were not considered to be the main cause in Libya. Furthermore, socioeconomic status of the children's families appears relevant.

Abstract
INTRODUCTION Permanent hearing impairment is the most common sensory disorder in newborns. The Universal Newborn Hearing Screening (UNHS) is widely adopted as a cost-effective procedure to achieve early identification and treatment of congenital hearing impairment, with the final goal of an improved linguistic and cognitive outcome for hearing impaired children. The Italian Ministry of Health has recently comprised UNHS in the Essential Level of Health Assistance. Nevertheless, programs still vary both across and within Italian Regions in terms of coverage, testing, referral and tracking protocols. In Friuli-Venezia Giulia region the program for the early identification of newborn and childhood hearing impairment is operative since 2012. In order to minimize the lost to follow-up cases, UNHS and childhood hearing surveillance activities have been organized in close collaboration among birth centres, paediatric audiology services, territorial Family Paediatricians and the sole regional centre for paediatric hearing loss management. MATERIAL AND METHODS We performed a five years' retrospective analysis of the UNHS experience in Friuli-Venezia Giulia comparing the UNHS activity of year 2013 and year 2017. The focus of the study concerns the "missing" cases. Three different typologies of "miss" cases ("documentation-miss", "access-miss" and "pathway-miss") have been defined in correspondence with main reasons for their occurrence. RESULTS Births in Friuli-Venezia Giulia were 9465 and 8432, respectively in 2013 and 2017. International quality indicators improved with a gain of efficiency in 5 years' experience. However, "missing" cases were 486 in 2013 and 321 in 2017, mainly due to the lack of an efficient documentation system. CONCLUSION UNHS programs have proven to be valuable and cost-effective in Friuli-Venezia Giulia and other Italian regions. New resources and efforts are required to achieve a complete standardization and informatisation of the UNHS data to avoid documentation gaps. A possible strategy would point to the opportunity to unify data management systems for all the ongoing newborn screening programs (metabolic, hearing and visual), linking the integrated IT system with the regional repository of current datasets.

Abstract
BACKGROUND Hearing loss in newborns and children is a public health concern, due to high prevalence and negative effects on their development. Early detection and intervention of childhood hearing loss may mitigate these negative effects. Population-based newborn hearing screening programs have been established worldwide to identify children at risk for congenital hearing loss and to follow children at risk for late onset or progressive hearing loss. This article presents the protocol for a systematic review that aims to review the risk factors associated with permanent hearing loss in children, including congenital, early, or late onset. Risk factors associated with progressive hearing loss will be investigated as a secondary aim. METHODS Scientific literature from the following databases will be investigated: MEDLINE, Ovid MEDLINE(R) Daily and Ovid MEDLINE(R), Embase, and CINAHL. The primary outcome is a permanent bilateral or unilateral hearing loss with congenital onset or onset during childhood (birth to 18 years). The secondary outcome is progressive hearing loss. Studies must report data on risk factors associated with permanent hearing loss; risk factors may be present at birth or later and result in immediate or delayed hearing loss. Randomized controlled trials, quasi-experimental studies, nonrandomized comparative and non-comparative studies, and case series will be included. The risk of bias will be assessed using the Qualitative Assessment Tool for Quantitative Studies (McMaster University). If aggregation of data is possible for a subsection of studies, we will pool data using meta-analysis techniques. If aggregation of data is not possible, a qualitative synthesis will be presented. We will assess the quality and strength of the overall body of evidence using the Grading of Recommendations Assessment, Development and Evaluation (GRADE). The systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations. DISCUSSION The resulting information will inform the update of a provincial audiological surveillance protocol for the Ontario Infant Hearing Program and will be applicable to early hearing detection and intervention (EHDI) programs worldwide. SYSTEMATIC REVIEW REGISTRATION We have registered the protocol in the International Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42018104121.

Abstract
Objective: Universal newborn hearing screening (UNHS) uses otoacoustic emissions testing (OAE) and auditory brainstem response testing (ABR) to screen all newborn infants for hearing loss (HL), but may not identify infants with mild HL at birth or delayed onset HL. The purpose of this review is to examine the role of genetic screening to diagnose children with pre-lingual HL that is not detected at birth by determining the rate of children who pass UNHS but have a positive genetic screening. This includes a summary of the current UNHS and its limitations and a review of genetic mutations and screening technologies used to detect patients with an increased risk of undiagnosed pre-lingual HL.Design: Literature review of studies that compare UNHS with concurrent genetic screening.Study sample: Infants and children with HLResults: Sixteen studies were included encompassing 137,895 infants. Pathogenic mutations were detected in 8.66% of patients. In total, 545 patients passed the UNHS but had a positive genetic screening. The average percentage of patients who passed UNHS but had a positive genetic screening was 1.4%.Conclusions: This review demonstrates the positive impact of concurrent genetic screening with UNHS to identify patients with pre-lingual HL.

Abstract
BACKGROUND The Israeli Newborn Hearing Screening Program (NHSP) began operating nationally in January 2010. The program includes the Otoacoustic Emissions (OAE) test for all newborns and Automated Auditory Brainstem Response (A-ABR) test for failed OAE and infants at risk for auditory neuropathy spectrum disorders. NHSP targets are diagnosis of hearing impairment by age three months and initiation of habilitation by six months. OBJECTIVES (1) Review NHSP coverage; (2) Assess NHSP impact on age at diagnosis for hearing impairment and age at initiation of habilitation; (3) Identify contributing factors and barriers to NHSP success. METHODS (1) Analysis of screening coverage and referral rates for the NHSP; (2) Analysis of demographic data, results of coverage, age at diagnosis and initiation of habilitation for hearing impaired infants pre-implementation and post-implementation of NHSP from 10 habilitation centers; (3) Telephone interviews with parents whose infants failed the screening and were referred for further testing. RESULTS The NHSP coverage was 98.7% (95.1 to 100%) for approximately 179,000 live births per year for 2014-2016 and average referral rates were under 3%. After three years of program implementation, median age at diagnosis was 3.7 months compared to 9.5 months prior to NHSP. The median age at initiation of habilitation after three years of NHSP was 9.4 months compared to 19.0 prior to NHSP. Parents (84% of 483 sampled) with infants aged 4-6 months participated in the telephone survey. While 84% of parents reported receiving a verbal explanation of the screening results, more than half of the parents reported not receiving written material. Parental report of understanding the test results and a heightened level of concern over the failed screen were associated with timely follow-up. CONCLUSIONS The findings indicate high screening coverage. The program reduced ages at diagnosis and initiation of habilitation for hearing impaired infants. Further steps needed to streamline the NHSP are improving communication among caregivers to parents to reduce anxiety; increasing efficiency in transferring information between service providers using advanced technology while ensuring continuum of care; reducing wait time for follow-up testing in order to meet program objectives. Establishment of a routine monitoring system is underway.

Abstract
Children hospitalized in Neonatal Intensive Care Units (NICU) present an increased risk for Sensorineural Hearing Loss (SNHL) due to prematurity, hypoxia-ischemia, hyperventilation, low birth weight and the use of ototoxic drugs. The aim of this study was to assess the prevalence of SNHL in newborns hospitalized in a NICU using Transient Evoked Otoacoustic Emissions (TEOAE) and Automated Auditory Brainstem Responses (A-ABR) and analyze the associated risk factors. A sample of 153 newborns hospitalized in NICU underwent TEOAE, A-ABR and clinical ABR to evaluate the presence of hearing deficits. Prevalence of SNHL was calculated and odds ratio for specific risk factors was measured. One-hundred fifteen babies (86.7%) presented normal hearing at TEOAE and A-ABR. Fifteen children had a REFER response at TEOAE and a PASS response at A-ABR. Twenty-five children (16.3%) had a REFER A-ABR and were addressed to clinical ABR. A diagnosis of SNHL was made in 12 (7.8%) newborns. An increased risk of SNHL was observed in preterm children <28 weeks (p=0.0135), in children with neurological disorders (p=0.02), that underwent surgery (p=0.0002), affected from premature retinopathy (p=0.0006), craniofacial malformation (p=0.007) and that had sepsis (p=0.04). Additional risk factors for SNHL in our sample were a maternal disease during pregnancy (p=0.0011), cesarean delivery (p<0.0001) and a twin pregnancy (p<0.0001). SNHL in newborns is correlated with hospitalization in NICU. An accurate hearing screening associated to a rigorous clinical medical collection of data is necessary to promptly identify cases of SNHL in children with a special attention to those hospitalized in NICU and plan proper intervention.

Abstract
OBJECTIVES To explore the pathogenic causes of a proband who was diagnosed with non-syndromic hearing loss. METHODS We performed targeted capture of 159 known deafness-related genes and next-generation sequencing in the proband who was tested negative for the twenty hotspot variants in four common deafness-related genes(GJB2, GJB3, SLC26A4 and MTRNR1); Clinical reassessments, including detailed audiological and ocular examinations were performed in the proband and his normal parents. RESULTS We identified a novel heterozygous variant of CDH23:c.4567A > G (p.Asn1523Asp) in exon 37 (NM_022124), in conjunction with a reported mutation of CDH23:c.5101G > A (p.Glu1701Lys) in exon 40, to be a potentially pathogenic compound heterozygosity in the proband. The unaffected father has a heterozygous variant of CDH23:c.4567A > G, and the normal mother has another heterozygous variant, CDH23:c.5101G > A. The novel variant was absent in the 1000 Genomes Project. The clinical reassessments revealed binaural profound sensorineural hearing loss (DFNB12) without retinitis pigmentosa in the proband. CONCLUSIONS This study demonstrates that the novel variant c.4567A > G (p.Asn1523Asp) in compound heterozygosity with c.5101G > A (p. Glu1701Lys) in the CDH23 gene is the main cause of DFNB12 in the proband. Simultaneously, this study provides a foundation to further elucidate the CDH23-related mechanisms of DFNB12.

Abstract
Purpose of Review The aim of this report is to review current literature regarding the work-up and management of congenital sensorineural hearing loss. Recent Findings Diagnostic evaluation of a newborn with sensorineural hearing loss begins with a complete audiologic evaluation and comprehensive history and physical exam. This review presents a diagnostic algorithm for the work-up of congenital hearing loss, focusing on the three following modalities: cytomegalovirus testing, genetic evaluation, and imaging. Summary Newborn hearing loss is a common problem and may be attributed to genetic and non-genetic factors. Complete diagnostic evaluation and treatment are essential for preventing delays in language development. Treatment consists of early intervention services and consideration of hearing aid amplification and cochlear implantation.

Abstract
INTRODUCTION Several studies have shown that early identification of childhood hearing loss leads to better language outcomes. However, delays in the confirmation of hearing loss persist even in the presence of well-established universal newborn hearing screening programs (UNHS). The objective of this population-based study was to document the proportion of children who experienced delayed confirmation of congenital and early onset hearing loss in a UNHS program in one region of Canada. The study also sought to determine the reasons for delayed confirmation of hearing loss in children. METHODS Population level data related to age of first assessment, age of identification and clinical characteristics were collected prospectively for all children identified through the UNHS program. We documented the number of children who experienced delay (defined as more than 3 months) from initial audiologic assessment to confirmation of hearing loss. A detailed chart review was subsequently performed to examine the reasons for delay to confirmation. RESULTS Of 418 children identified from 2003 to 2013, 182 (43.5%) presented with congenital or early onset hearing loss, of whom 30 (16.5%) experienced more than 3 months delay from initial audiologic assessment to confirmation of their hearing disorder. The median age of first assessment and confirmation of hearing loss for these 30 children was 3.7 months (IQR: 2.0, 7.6) and 13.8 months (IQR: 9.7, 26.1) respectively. Close examination of the factors related to delay to confirmation revealed that for the overwhelming majority of children, a constellation of factors contributed to late diagnosis. Several children (n = 22; 73.3%) presented with developmental/medical issues, 15 of whom also had middle ear dysfunction at assessment, and 9 of whom had documented family follow-up concerns. For the remaining eight children, additional reasons included ongoing middle ear dysfunction for five children, complicated by family follow-up concerns (n = 3) and mild hearing loss (n = 1) and the remaining three children had isolated reasons related to family follow-up (n = 1) or mild hearing loss (n = 2). CONCLUSION Despite the progress made in the early detection of pediatric hearing loss since UNHS, a substantial number of children referred for early assessment can experience late confirmation and intervention. In particular, infants with developmental and/or medical issues including middle ear disorders are at particular risk for longer time to confirmation of hearing loss.

Abstract
One of the rare genetic diseases with sensory hearing loss is the microdeletion 7q syndrome. First described in the 1990s, only 7 cases of patients with this disease are described in the literature. Although this mutation is not well known, otological treatment is necessary if the DFNA5 gene is affected. A mutation in this gene leads to progressive hearing loss. Affected children therefore need regular evaluation of their hearing to ensure adequate treatment with hearing aids at early stages. We now present a case of an affected child with sensory hearing loss, mental retardation and anogenital malformations. In the following we describe the course of disease and possible treatment options. We especially describe the possibility of cochlear implantation. We can show with this case report that, even though massive mental retardation is shown, cochlear implantation is useful in this patient. Associated disabilities as cardiac and pulmonary problems may occur and should be treated before cochlear implantation. This is the first report of cochlear implantation in a child affected with microdeletion 7q syndrome.

Abstract
Infants with congenital deafness caused by severe bilateral inner ear malformations frequently suffer from severe hearing loss and poor balance. Unfortunately, the use of hearing aids is usually ineffective in recovering hearing, necessitating cochlear implants. We report a case of a 6-year-old boy with congenital deafness and bilateral inner ear malformations (right side, incomplete partition type I [IP-I]; left side, common cavity deformity). Hearing aids had a remarkable effect in this patient, enabling sufficient and favorable hearing recovery such as to allow the patient to engage in daily conversations. Per-rotatory nystagmus was recorded on an electronystagmogram for both right and left rotations in a damped rotational chair test. It is rare for deaf children with severe bilateral inner ear malformation to demonstrate favorable development in hearing and good equilibrium function. Our findings suggest that auditory–vestibular hair cells in this patient may have been partially preserved despite IP-I in the right ear and common cavity deformity of the left ear.

Abstract
Mutations in gap junction proteins encoding beta connexions are believed to be a major cause for congenital hearing loss. The purpose of this study was to do comparative analyses of frequencies of most prominent mutations responsible for congenital deafness. Using fluorescence PCR method, the entire coding region of GJB2 gene, GJB3 gene, and SLC26A4 was analyzed. Direct DNA sequencing was used to analyze mutations in these genes among unrelated 2,674 cases of newborns. Also, 12S rRNA mutation was also studied in these cases. In 2,674 cases of newborns from June 2013 to June 2014, found deafness mutation in 137 cases (5.12 % of carrier rate), carrying GJB2 mutations in 68 cases (2.54 % of carry rate), GJB3 mutations in 10 cases (0.37 % of carry rate), SLC26A4 mutations in 54 cases (2.02 % of carry rate), and mitochondrial 12S rRNA mutations in five cases (0.19 % of carry rate). The study concludes that GJB2 gene mutation is the most common and mitochondrial 12S rRNA mutations are the least common mutation for congenital hearing loss in Chinese newborns.

Abstract
Auditory brainstem implants (ABIs) provide auditory perception in patients with profound hearing loss who are not candidates for the cochlear implant (CI) because of anatomic constraints or failed CI surgery. Herein, the authors discuss (1) preoperative evaluation of pediatric ABI candidates, (2) surgical approaches, and (3) contemporary ABI devices and their use in the pediatric population. The authors also review the surgical and audiologic outcomes following pediatric ABI surgery. The authors' institutional experience and the nearly 200 cases performed in Europe and the United States indicate that ABI surgery in children can be safe and effective.

Abstract
Hearing loss is the most common sensory disorder in the USA. The diagnosis of congenital hearing loss starts with newborn hearing screening, which is best performed with auditory brainstem evoked responses in order to avoid the risk of missing auditory neuropathy spectrum disorder. A careful history and physical exam can occasionally help reveal the etiology for congenital hearing loss. Imaging studies, either CT temporal bones or MRI of the internal auditory canals without gadolinium, and genetic testing, in particular for connexin 26, connexin 30, and Pendred syndrome, are the most useful diagnostic tests. Management of congenital hearing loss involves early fitting of amplification. Early cochlear implantation, preferably before 2 years of age, should be strongly considered for children with bilateral severe hearing loss.

Abstract
Aural atresia is a rare congenital malformation of the external and middle ear. There are several syndromic associations of this anomaly with those involving the first and second branchial arches. Occurrence of aural atresia with sclerosing skeletal dysplasia is unknown and has never been reported. The co-existence of a sclerosing dysplasia can make the surgical treatment in aural atresia difficult and risky; and the auditory improvement may not be as expected. Moreover, internal auditory canal narrowing and hence sensorineural hearing loss in sclerosing dysplasia might add to the already existing conductive hearing loss in such patients. In this case report we have described an unknown association of bilateral microtia with sclerosing skeletal dysplasia (autosomal dominant osteopetrosis) and clinical implications of these two conditions occurring together leading to a change in the management plan.

Abstract
OBJECTIVES To share our experience in cochlear implanted patients with Jervell and Lange-Nielsen syndrome (JLNS), to review the literature results and to disclose precautions which have to be taken dealing with these patients. MATERIALS AND METHODS Electrocardiograms (ECG) of 503 children with congenital bilateral profound hearing loss which were cochlear implanted in cochlear implant center of a tertiary hospital were evaluated for long QT syndrome. Clinical reports of the patients with JLNS were evaluated and a review of literature performed. RESULTS The prevalence of disease was 0.79% (four cases) in our center which is in the range of literature reports (0-2.6%). None of our patients had a history of syncopal attack. Two patients (50%) were born from parents with consanguineous marriage. Considering all precautions their cochlear implant surgeries were done uneventfully. A review of the literature has identified sixteen reports on cochlear implantation in a total of 38 children with JLNS. Similar to our cases none of the authors reported cardiac events during device switch-on. Nine available reports about the outcome of cochlear implantation in these patients indicated good auditory outcome. CONCLUSION It is recommended that all congenitally deaf patients have an ECG taken as a part of the evaluation. As auditory stimuli is reported to be a specific trigger, it is prudent to activate the processor with continuous heart monitoring even though there is no reported cardiac event during device switch-on. Cochlear implantation can be performed relatively safely in these patients if necessary precautions have been taken appropriately and their auditory outcome is good. Triggers of the cardiac events should be avoided throughout their life.

Abstract
OBJECTIVE To investigate the association of eight connexin genes (GJB2, GJB4, GJA1P1, GJB6, GJB3, GJA1, GJB1, and GJC3) and the SLC26A4 gene with congenital hearing impairment among infants in a universal newborn hearing screening program. METHOD From September 2009 to October 2013, the consecutive neonates born in all six branches of Taipei City Hospital were enrolled. Infants who failed the newborn hearing screening and were diagnosed with hearing impairment underwent the genetic analyses. RESULT 15,404 neonates were born at Taipei City Hospital, and 15,345 neonates underwent newborn hearing screening. Among them, 32 infants were diagnosed with unilateral or bilateral hearing impairment. 26 of them underwent analyses of the connexin genes and the SLC26A4 gene. Of the connexin genes, two infants carried a GJB3 mutation (heterozygous c.580G>A and heterozygous c.520G>A, respectively). Only one infant carried a GJB2 mutation (homozygous c.235delC). One infant carried a GJA1P1 mutation (heterozygous c.929delC) and another carried a GJB4 mutation (heterozygous c.302G>A). Additionally, one infant carried a GJA1P1 novel variant (heterozygous c.1081C>T). Another infant carried a GJA1 novel variant (heterozygous c.1-33C>G). Of the SLC26A4 gene, one infant carried heterozygous c.919-2A>G mutation and a novel variant (heterozygous c.164+1G>C), and high-resolution computed tomography (HRCT) of the temporal bone revealed bilateral enlarged vestibular aqueducts. One infant carried heterozygous c.919-2A>G mutation and no inner ear anomalies were demonstrated by HRCT of the temporal bone. Another infant carried a novel variant (heterozygous c.818C>T). CONCLUSION These results provide a genetic profile of the connexin genes and SLC26A4 gene among infants with hearing impairment detected by a universal newborn hearing screening program in Taiwan. Further studies and long-term follow up of this cohort are warranted to determine the pathogenicity of each variants and the long-term hearing consequence.

Abstract
OBJECTIVE Hearing is a critical ability for the development of a child's speech and language. Many studies in different countries have shown the universal newborn hearing screening and early intervention has greatly reduced the negative impact caused by congenital hearing loss. The first universal newborn hearing screening program in Taiwan took place in MacKay Memorial Hospital in 1998 and was subsequently endorsed by the government. The incidence of bilateral congenital hearing impairment in Taiwan is approximately 2.6 per 1000 live birth. The aim of this paper is to analyze the age of diagnosis, hearing aid fitting, and intervention of congenitally hearing impaired children with and without hearing screening after public awareness and government endorsement of newborn hearing screening. MATERIALS AND METHODS There were 263 hearing impaired children participated in this study, receiving their auditory habilitation therapy at Children's Hearing Foundation from 2006 to 2010. 114 of those children went through newborn hearing screening and 149 without it. The age of diagnosis, hearing aid fitting, and auditory intervention were compared between these two groups. The age of diagnosis and intervention of congenitally hearing impaired children among different years were analyzed too. RESULTS The average age of diagnosis was 8.7 months, the age of hearing aid fitting was 12.4 months and age of auditory intervention was 18.8 months for the group of hearing impaired children with newborn hearing screening. For hearing impaired children without newborn screening, their average age of diagnosis was 27.5 months; age of hearing aid fitting was 31.3 months and age of auditory intervention was 40.5 months. There were significant differences in the age of diagnosis, hearing aid fitting and auditory intervention between congenitally hearing impaired children with and without hearing screening. CONCLUSIONS This research indicates that newborn hearing screening facilitates early identification, diagnosis and intervention of congenitally hearing impaired children in Taiwan. The age of identification, diagnosis and intervention of congenital hearing impaired children has also been reduced gradually over the years after government endorsement of newborn hearing screening in Taiwan.

Abstract
A study was conducted to determine why there was a delay in detection of hearing loss in congenitally hearing impaired children in rural India. It was found that although the parents of these children visited a primary care physician, relevant information regarding investigation and rehabilitation of hearing loss was not available to the patient. In the absence of a universal hearing screening programme in this country, it is a matter of importance to strengthen this aspect of community otolaryngology in the undergraduate ENT programme. There is also a need for continuing medical education programmes for primary care physicians regarding available methods of investigation and rehabilitation for a hearing impaired person.

Abstract
The GJB2 gene is located on chromosome 13q12 and it encodes the connexin 26, a transmembrane protein involved in cell-cell attachment of almost all tissues. GJB2 mutations cause autosomal recessive (DFNB1) and sometimes dominant (DFNA3) non-syndromic sensorineural hearing loss. Moreover, it has been demonstrated that connexins are involved in regulation of growth and differentiation of epidermal tissues. Hence, mutations in GJB2 gene, which is responsible for non-syndromic deafness, may be associated with an abnormal skin and hair phenotype. We analyzed hair samples from 96 subjects: a study group of 42 patients with hearing impairments of genetic origin (38 with a non-syndromic form, 4 with a syndromic form), and a control group including 54 people, i.e. 43 patients with other, non-genetic hearing impairments and 11 healthy volunteers aged up to 10 years old. The surface structure of 49 hair samples was normal, whereas in 45 cases it was altered, with a damaged appearance. Two hair samples were considered unclassifiable: one from the patient heterozygotic for the pendrin mutation (Fig. 2C), the other from a patient from Ghana with a R134W mutation (Fig. 2D). Among the 43 altered hair samples, 31 belonged to patients with connexin mutations and the other 12 came from patients without connexin mutations.
