The follow-up results of newborn hearing screening of Gaziosmanpasa Taksim Research and Training Hospital.

Abstract

This study aimed to present the results of newborns who were referred to advanced audiology centers after newborn hearing screening, and to determine concordance of our results with the American Academy of Pediatrics guidelines about the ages of hearing loss, aid fitting, and cochlear implantation. A total of 7502 newborns were screened in Gaziosmanpaşa Taksim Research and Training Hospital between March 2014 and June 2016 using the transient otoacustic emissions test as the first two steps and automated auditory brainstem response test for the third step. Newborns who had risk factors were screened using the automated auditory brainstem response only. Newborns who failed the screening tests were referred to advanced audiology centers. Of the 7502 newborns, 6736 (90%) completed the screening. The ratio of hearing loss was 0.08%. Six of 62 newborns who failed auditory brainstem response test and were referred to advanced audiology centers had severe bilateral hearing loss. One of the patients was not fitted with a hearing aid because the family refused it. The other one was not fitted an aid and did not undergo cochlear implantation because of severe and treatment-resistant acute otitis media. The age of diagnosis for the rest was before three months, and except for one patient, hearing aid fitting was before six months. The age of cochlear implantation was 12 months for two patients and 14 months for two patients. Ninety percent of patients completed the screening, the age of diagnosis for hearing loss was before three months and aid fitting was before six months, except for one patient. The results of the study were compatible with the diagnosis and treatment guidelines of the American Academy of Pediatrics.
