Abstract

Hearing is fundamental part of infant's global development, revealing then, reveling then, the importance of Universal neonatal hearing screening (UNHS) which will enable an early audiological diagnosis. The results for the neonatal hearing screening may be presented as a result PASSED or FAILED. The ones presented as, failed will then be retested. If the results are still the same, however, the infant must be forwarded to the audiological diagnosis before his/her sixth month of life. In the audiological diagnosis it is possible to check the family history, study the risk factors associated with hearing loss and execute objective procedure for the detection of alteration in the auditory system. An early audiological diagnosis enables early intervention, providing, therefore a better prognosis. Objective: Analyse the audiological diagnosis from infants who failed retest of the neonatal hearing screening. Method: The research will be performed at the Laboratory of Diagnostic Audiology Assessment of Children at Unicamp. The infants who failed both the neonatal hearing screening and the it's retest will be forwarded to do audiologic diagnosis. For this diagnosis of hearing loss the following procedures will be made: anamnesis, evoked otoacoustic emission (EOAE), evoked auditory brainstem response (ABR), tympanometry and acoustic reflex testing. All of these procedures' results will then be tabulated and statistically analyzed by a researcher. (AU)
