Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 1
Abstract
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 set-up, 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 48th 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.
