Abstract:
Objective To investigate the usage of distortion product otoacoustic emissions(DPOAE) in normal infants hearing screening.Methods One hundred infants(200 ears) without clinical condition of illness were checked in GSI 70 DPOAE screening.The pure tones were 2,3,4 kHz,the OAE screener scored the test result as a pass,when the responses were above the PASS/REFER line and the signal-to-noise was at least 10 dB.Results Ninty-four infants(188 ears) passed hearing screening. Four infants(8 ears) with ceruminous impaction didn′t pass screening;after extracting impacted cerumen from the external auditory meatus,the 4 infants(8 ears) passed screening.Two infants(2 ears) with secretory otitis media didn′t pass screening,but after medicine treatment for 1 week,they passed screening too.Conclusion DPOAE has advantages in infants hearing screening.J Appl Clin Pediatr,2006,21(3):168-169
