A Clinical Study of Hearing Screening With Oae in 300 Highrisk Newborns
INTRODUCTION Neonatal deafness is diagnosed late, approximately at 24 to 36 months of age. At this age rehabilitation procedures are unable to ensure complete development of speech and thus prevent the full participation of the deaf child in social living.2 OBJECTIVES Our aim of study is to identify various risk factors adversely affecting hearing and to identify hearing impairment in high-risk newborn. MATERIALS AND METHODS 300 new-borns, born out of high risk pregnancy or intranatal or neonatal complications, requiring NICU admission, were screened for hearing loss with transient evoked otoacoustic emission .Results mentioned in terms of 'pass' (normal hearing) or 'refer' (who needs further evaluation). Follow up OAE examination was done in refer cases after 7 to 10 days. Brainstem evoked response audiometry (BERA) done in those cases, those 'failing' on second examination. Tympanometry done in those cases who shows normal BERA examination to rule out middle ear pathology2, 5, 9, 10. RESULTS Out of 300 new-borns 24 showed OAE'refer' at first examination and out of these 24 'refer' , 18 were 'fail' on second OAE examination. Out of these 18 who underwent BERA examination, 12 showed pathological deafness and 6 showed normal BERA examination .These 6 new-borns underwenttympanometry study and showed normal results. CONCLUSION Incidence of hearing loss in high risk new-borns in this study was 8 % .Thus hearing screening should be implemented at all levels of health care facilities .If all new-borns could not be screened due to infrastructural problem then at least the high risk new-borns must be screened.
Newborns Hearing Screening with Otoacoustic Emissions and Auditory Brainstem Response
Journal of Community Medicine and Public Health Research
Hearing loss in newborns is a serious matter, if it is not quickly diagnosed and starts early intervention, a child will experience social, speech, language, cognitive, and academic impairments. There is a method of hearing screening in newborns, which is divided into two types, universal newborn hearing screening, and targeted newborn screening. Both of these methods use OAEs and ABR as objective examination tools. The hearing screening method varies in each country, this difference is based on the test equipment used, age, frequency, professionals involved in screening, referral procedures, funding, and coverage areas. Indonesia uses two stages of screening, while Italy, America, Nigeria, France, India, and Poland use two to five stages of screening. Hearing screening of newborns using OAEs and ABR has a sensitivity of 100% and specificity of 99,3%.
Hearing screening using OAE and ABR
IOSR Journals , 2019
Objective: This study included screening of hearing assessment of neonates and children using combined automated auditory brainstem response audiometry and otoacoustic emission testing in a tertiary care setup , to assess the prevalence of neonatal hearing loss and also to manage the children with profuse SNHL. Methods: A retrospective study was conducted between September 2016-September 2018 in Pacific Medical College and Hospital, Udaipur .First, all of neonates were evaluated by OAE within 24th to 48 th hours of birth. If responses of OAE were failing, they were retested in 1 month and 3 month after birth by OAE. Also, Neonates failing on above were assessed by ABR at the age of 6 months. A total of 1518 newborns were assessed by OAE, failing in it again after 3 months were asked for ABR testing. A bunch of 236 children were tested for ABR, among those 147 patient were confirmed of profound sensory neural hearing loss. Children who were confirmed of sensorineural hearing loss considered for rehabilitation either by prescribing hearing aids or cochlear implantation if fulfilled the criteria for the above. Results: Neonatal hearing screening using OAE and BERA is a feasible service. The estimated prevalence of confirmed hearing loss was comparable to that in literature. In our study 9.6 % children presented to our health care system within 2 years were found to have profound SNHL. Rehabilitation by either using hearing aids and surgically implanted stimulating device were enormously helpful to children who were in regular follow up.
Early Detection of Hearing Impairment in Neonates - Screening by Otoacoustic Emission Test
2021
BACKGROUND Approximately 3 per 1000 live births suffer from congenital hearing loss in India. If detected before the age of 6 months, their mental, social and intellectual growth can be restored by early intervention and rehabilitation. Their speech development and social integration depends highly on early detection of hearing loss, at least before the first birthday. We wanted to screen all new-borns for hearing and assess the incidence of hearing impairment in at risk and no risk cases by using otoacoustic emissions. We also wanted to evaluate the two-stage testing by OAE in screening programme. METHODS The present study was conducted from Feb. 1st 2013 to Jan. 31st 2015. A total of 849 infants have been studied of which 63 had high risk factors. RESULTS The overall incidence of hearing impairment was found to be 3.75 / 1000 births in no-risk group whereas 61.22 / 1000 were found in high risk group. CONCLUSIONS Early detection of hearing loss in infants by otoacoustic emission (O...
Hearing loss assessed by universal newborn hearing screening—The new approach
International Journal of Pediatric Otorhinolaryngology, 2007
Objective: Universal hearing screening at the delivery centers enable early detection of hearing impairment. Since the 2002, hearing screening in neonates is performed in all Croatian delivery centers. The aim of this study was to propose the retest after 3 weeks period to those neonates with presumably hearing impairment demonstrated by evoked otoacoustic emission (E-OAE) method. Second aim was to asses the prevalence of hearing impairment in the Northern Adriatic region of Croatia. Patients and methods: Investigation has been conducted at the Department of Gynecology and Obstetrics, University Hospital in Rijeka, Croatia, in the period from 16 October 2002 to 31 December 2006. The hearing screening was performed in all newborns immediately before their discharge from the hospital, using the E-OAE method. Newborns with a possibility of hearing impairment were invited for retesting after 3 weeks, using the same method. Those newborns, whose repeated screening suggested a possible hearing impairment, were sent to an audiologist. Results: The hearing screening was performed by E-OAE method in 11.746 (98.9%) out of 11.869 newborns. The positive result indicating hearing impairment had 5.7% (676) children. These children where retested 3 weeks later using same method and only 128 (1.1%) of them still had positive results. Definite bilateral hearing impairment was confirmed by audiologists in seven children, which accounts for the total incidence of hearing impairment of 0.6%. Conclusions: Universal newborn hearing screening provides early detection of hearing loss. Retesting after 3 weeks with the same--E-OAE method we raised the specificity of E-OAE method, eliminating false-positive results (4.2%), decreased the attendance of healthy children to the audiologist center and most likely lowering the total costs and eventual parental and/or children stress. #

Objective: Hearing screening programs in infancy should identify hearing impairment as early as possible. The two common programs utilize either objective neonatal tests (oto-acoustic emissions (OAE) or automatic auditory brainstem responses (aABR)) or behavioral screening at 7-9 months of age. Most countries employ only one of these options. The uniqueness of this study is the comparison of both hearing screening programs on the same group of children. Methods: The study was conducted on 1545 children born between the years 1999 and 2003 who were followed up in public well baby clinics in the Jerusalem district. The children were tested with transient oto-acoustic emissions (TEOAE) before discharge from the neonatal ward, and later, at the age of 7-9 months, underwent a behavioral hearing screening test in a public well baby clinic. The results of both hearing screening programs were compared. Results: The compliance rates were 99.7% for the neonatal testing and 83% for the 7-9 months behavioral testing (p = 0.0001).

that found a significant number of infants who passed an automated auditory brainstem response (A-ABR) screening after failing an initial otoacoustic emission (OAE) screening later were found to have permanent hearing loss in one or both ears. Method: Similar to the approach used by F. H. Bess and J. Paradise (1994), this article addresses the public health tenets that need to be in place before screening programs, or in this case, a change in screening practice (use of a 2-step screening protocol) can be justified. Results: There are no data to suggest that a 2-step OAE/A-ABR screening protocol should be avoided. Conclusion: Research is needed before any change in public policy and practice surrounding current early hearing detection and intervention programs could be supported.

Objective. Ninety percent of all newborns in the United States are now screened for hearing loss before they leave the hospital. Many hospitals use a 2-stage protocol for newborn hearing screening in which all infants are screened first with otoacoustic emissions (OAE). No additional testing is done with infants who pass the OAE, but infants who fail the OAE next are screened with automated auditory brainstem response (A-ABR). Infants who fail the A-ABR screening are referred for diagnostic testing to determine whether they have permanent hearing loss (PHL). Those who pass the A-ABR are considered at low risk for hearing loss and are not tested further. The objective of this multicenter study was to determine whether a substantial number of infants who fail the initial OAE and pass the A-ABR have PHL at ϳ9 months of age.
