Abstract: Background: The incidence of congenital hearing loss in newborn population is greater than the combined incidence of all the metabolic conditions that we currently screen with blood investigations. Significant hearing loss is one of the major abnormalities present at birth. One in every thousand children is born profoundly deaf. Four times as many are born with moderate or severe bilateral hearing loss. Infants in Neonatal intensive care units are 10 - 20 times more likely to have significant hearing loss than healthy population. Aims: To assess the hearing status of newborns delivered in our hospital with help of otoacoustic emission testing and assess its importance for early intervention. Study Design: A Retrospective study. Setting: ENT Department, GMERS Medical College and Hospital, Sola, Ahmedabad. Materials and Methods: It was a retrospective study carried out in a tertiary care centre ENT Department Sola, Ahmedabad for a period of one year from APRIL 2022 TO OCTOBER 2022 Total 100 cases of newborn were included in this study. The parameters included in the study were prenatal and intranatal and post natal causes of newborn hearing loss. Result: Author is presenting a case study of 100 patients with newborn delivered in sola civil hospital .Out of 100 patients, 54 patients had PASS in OAE and 46 patients had REFER in OAE. Out of 46 patient, those who had REFER in OAE underwent a repeat OAE after 3 months, Out of these 46 patients, 34 patients obtained PASS and 12 patients had REFER. Out of those 12 patients who had REFER in OAE, BERA was performed. In BERA, 2 patients had Profound Sensorineural hearing loss and 10 patients had normal hearing. Conclusions: This is a retrospective study of newborn hearing screening by using OAE. This study used to detect any hearing loss as much as early possible. This is cost effective, easy and fast technique. By using OAE machine, newborn and child hearing screening can be done easily, low cost and non-invasive way.
