Abstract
Objective To study on the audiological characteristics of large vestibular aqueduct syndrome(LVAS)in young children.Methods 80 ears diagnosed as LVAS by Department of ENT in our hospital from May 2014 to May 2017 were selected as the observation group.while 80 ears diagnosed as non-LVAS were selected as the control group.Tympanometry,Otoacoustic emission,ABR and ASSR were performed on them.Results 69 ears were diagnosed as severe and extremely severe deafness,accounting for 89.61％.77 ears were all type A tympanogram.DPOAE of 77 ears were not elicited.The hearing curves of 34 ears(75.56％,34/45)showed there was an obvious difference between air and bone conduction thresholds at low frequency (0.25 kHz and 0.5 kHz),while high frequency decreased.The control group showed a full frequency hearing loss.ASNR of 41 ears (53.25％,41/77)were elicited by high intensity (≥90 dB nHL),with the mean latency of (2.97±0.31) ms.ASNR was not recorded in the control group.The reaction rate between 2 groups at 0.5 kHz frequency was significantly different (P＜0.05).While there was no significant difference at 1 kHz,2 kHz and 4 kHz (P＜0.05).Conclusion The young children with LVAS mostly have the characteristics of the high frequency hearing loss curve with significant air-bone gaps at low frequencies.ASNR negative phase waves are recorded in ABR tests.The audiological characteristics provide an important reference for initial diagnosis of LVAS.关键词
