Abstract:
Many features of transiently evoked otoacoustic emission(TEOE) are ideal for clinical use, including their ability to objectively measure cochlear function. TEOE can be used to accurately and efficiently screen for identification of neonatal hearing impairment. The purposes of this study are to provide the reference value of neonatal screening parameters, to evaluate the incidence and etiolgies of neonatal hearing loss, and to confirm the efficacy of neonatal screening. Data were collected from 1145 neonate subjects, the majority of whom is around 30 days of age. Reference values of TEOE are issued. Nine neonates proved to have sensorineural hearing loss of greater than moderate degree. Five of them had high risk factors of neonatal sensorineural hearing loss(SNHL), whereas other four did not. This study reconfirmed neonatal screening with TEOE is a valuable tool for early detection of the babies with SNHL. The babies with high risk factors have higher risk of SNHL(3.4%) than those without risk factors(0.4%). The baby without risk factors occupied some proportion of the babies with SNHL, which implies the necessity of TEOE screening in all neonates.
