“…The first screening done by DPOAE had a referral rate of 204(21.4%). This is comparable to the study done in Chennai by Vignesh et al 10 The referral rate of DPOAE can vary from 11-31% as reported by Barker et al is comparable to our study. 11 This variation could be because of criteria applied for pass/ refer.…”

Background: The aim of the study was to do universal hearing screening of all newborns using otoacoustic emission (OAE), to know the incidence and risk factors of hearing loss in neonates.Methods: This was a prospective observational study done in a tertiary care hospital in Mangalore city in Karnataka. 950 neonates were screened with distortion product otoacoustic emission (DPOAE) during the study period of one year from 2017 to 2018. A repeat test was done at one and a half months of age if the first test failed. Auditory brain stem evoked response (ABER) was performed at 3 months of age if both the tests failed. Babies with hearing loss were referred to ENT specialist for further management. Comparison of the variables was done by student’s t test and Chi-square test. P-value <0.05 was considered statistically significant.Results: Out of the 950 newborns screened with DPOAE test, 204 (21.4 %) babies had abnormal screen either in single or both ears. 7 out of 204 (3.43%) babies had abnormal OAE on repeat testing at one and half months. 2 out of 7 babies (0.96 %) had significant hearing loss ABER was performed at 3 months of age.Conclusions: Early identification by screening of hearing loss prevents a significant public health concern. Early recognition and intervention prior to 6 months have a significant positive impact on development.

“…The prevalence of congenital hearing loss in other studies were reported as 1 to 6 per 1000 screened babies, including both highrisk and well babies. 7,[17][18][19][20] The prevalence of congenital hearing loss in present study is much higher when compared to the other studies. In other studies, the study population was larger and also included a greater number of well babies than high-risk babies.…”

Background: Hearing plays a vital role in developmental of a child. Hearing loss not only affects the speech and language development of a child but also affects the social, emotional and intellectual development. Hearing is important in the first 2 years of life as this is the critical period for language acquisition. Thereby early detection and intervention for hearing loss is recommended. However, there are no standard protocols for newborn hearing screening. Hence, this study is undertaken to evaluate the appropriate protocol for early detection of hearing impairment in newborns and to ascertain the sensitivity and specificity of Distortion Product Oto-acoustic Emission (DPOAE) and Auditory Brainstem Response (ABR).Methods: A prospective study was conducted in the Department of Paediatrics and Department of Audiology and Speech Pathology in SRM Medical College Hospital and Research Centre. A total of 122 neonates were screened for hearing loss using both DPOAE and ABR before discharge from the hospital. A rescreening with ABR after 1 month was done for those infants who had hearing loss at the initial screening.Results: The study revealed that 16.4% of infants had hearing loss. The referral rate of DPOAE was 54.1% and ABR was 16.4%. ABR had higher passing rates when compared to DPOAE. In a combined screening with both DPOAE and ABR, 17 (13.9%) babies had failed DPOAE with abnormal hearing in ABR (True positives), 49 (40.2%) babies failed DPOAE but had normal hearing in ABR (False positives), 3 (2.5%) babies passed DPOAE but had hearing loss in ABR (False negatives) and 53 (43.4%) babies passed DPOAE and had normal hearing in ABR (True negatives). The association between the results of DPOAE and ABR was statistically significant (0.002). Auditory neuropathy was detected in 3 out of 122 neonates. All these 3 babies belonged to high-risk population. The prevalence of auditory neuropathy is 2.5% which is much lower when compared to other studies. The sensitivity and specificity of DPOAE is 85% and 51.9% respectively. The sensitivity and specificity of ABR was 100%.Conclusions: Present study concludes that the use of combination protocol using both DPOAE and ABR identifies babies with auditory neuropathy spectrum disorder and also ensures high sensitivity and acceptable specificity. Thus, helps in early identification and intervention of congenital hearing loss.

“…Referral rates in high risk babies were more than well born babies in both DPOAE and AABR testing as observed in other studies. Estimated prevalence of congenital hearing loss in this current population is 1.42 per 1000 babies (9). Approximately 55% of neonates in the o the neonatal intensive care unit had risk factors related to permanent hearing loss (2).…”

“…Two tests have been widely used for infant screening: click or transient evoked autoacoustic emissions (TEOAE) and auditory brainstem response (ABR). Both of these methods show high pass rates in newborn subjects (2,7,9). The report states that in India protocol used in 1st and 2nd stage of hearing screening are Transient Evoked Otoacoustic Emissions (TEOAE) alone and AABR are used in 3rd stage of hearing screening (9,10).…”

Amaç: Yenidoğan işitme taramalarında (UNHS) oto-akustik emisyonlar (OAE) ve otomatik beyin sapı yanıtının (ABR) birlikte kullanımı, işitme kayıplarının erken tanınmasını sağlamıştır. Bu çalışmanın amacı, otoakustik emisyonlar ve otomatik işitsel beyin sapı cevabı kullanılarak, Antakya'daki yenidoğan bebeklerde işitme kaybı sıklığını bulmaktır. Yöntem: Prospektif tasarlanan çalışma, 18 ay boyunca yenidoğan 7780 bebek ile Antakya'da yapıldı. Bütün yenidoğanlar üç aşamalı işitme tarama protokolü kullanılarak tarandı. Bulgular: 7780 yenidoğan bebeğin otoakustik emisyon ve bir ABR ile işitme taraması yapıldı. Üç aşamalı yapılan taramadan sonra, 50 yeni doğan bebek işitme kaybı tanısı aldı. Üçüncü muayene, otomatik beyin sapı yanıt odyometrisinden (aABR) oluşuyordu. Bu çalışma, popülasyonumuzda konjenital işitme kaybı prevalansının 1000 bebekte 6 olduğunu ortaya koymaktadır. Sonuç: Bulgularımız genel olarak literatür ile uyumludur. Üç aşamalı protokolün kullanılması TEOAE, DPOAE ve ABR, yenidoğan tarama programlarındaki teşhis edilemeyen işitme kayıplarında yanlış pozitif sonuçları önemli ölçüde azaltır. Özellikle ABR, yanlış pozitif sonuçları azaltırken tarama programının verimliliğini arttırır.
