Abstract
Neonatal hearing loss is a common health problem. Early detection, identification and
management prevent the development of hearing loss and its consequences such as delay
in speech and language development. The prevalence of sensorineural hearing loss
among all newborns has been reported to be 1 - 2 per 1000, whereas it rises to 1-2 per
100 newborns in with high-risk criteria. Recent research provides evidence for the value
of transient-evoked otoacoustic emissions (TEOAEs) in neonatal hearing screening. This
study is an experimental hearing screening using TEOAEs, carried out at the special care
nursery, Hospital Universiti Sains Malaysia aimed at detecting hearing loss in newborns,
to detennine the prevalence and size of the problem. A total number of 530 neonates
from the special care nursery were screened with TEOAEs using a two-stage process.
The first test was performed prior to discharge. Those who failed the first test were rescreened
after 4 weeks. Those who did not pass the second-stage TEOAE screening were
referred for diagnostic audiological evaluation for confirmation of hearing loss. All
newborns detected with hearing loss were found to be among high-risk group, in which 2
had neonatal jaundice, 1 with hydrocephalus, 1 with sepsis and 1 with premature birth
only failed on the left ear. The prevalence of hearing loss obtained in this study was 5
(0.94%) out of530 newborns.
