Sensitivity and specificity of portable transient otoacoustic emission (TEOAE) in newborn hearing screening.

Early identification and management of hearing impairment is very valuable. The goal standard measurement of hearing loss is by brainstem evoked response (BSER). This prospective study was conducted in Hospital University Kebangsaan Malaysia (HUKM) to determine the sensitivity and specificity of transient evoked otoacoustic emission (TEOAE) as a screening tool for hearing impairment from February 1999 to February 2000. One hundred and thirty-three newborns from postnatal ward and seventy-eight newborns from neonatal intensive care unit (NICU) were screened for possible hearing loss using portable TEOAE. This study showed that TEOAE is a very sensitive but moderately specific screening tool.
