摘　　要：目的 :探讨致聋因素在致单耳发病时对对侧耳潜在的影响。方法 :利用OtodynamicILO96耳声发射分析仪 ,对 35例单侧耳蜗性聋患者 (分为 5组 :发病 2个月以内的突发性聋 9例为S1组 ,发病 1年以上的突发性聋 6例为S2 组 ,梅尼埃病 13例分为M1、M2 组 ,不明机理的耳蜗性聋 7例为UNK组 )对侧耳瞬态诱发性耳声发射 (TEOAE)的反应幅值、反应重复率及频带的重复率 ,畸变产物耳声发射 (DPOAE)曲线特点及 1～ 5kHz反应幅值进行分析比较。结果 :S1组、M2 组TEOAE的反应幅值、反应重复性、频带重复性明显低于正常值 ,DPOAE幅值明显降低 ;S2 组、M1组、UNK组TEOAE和DPOAE正常。结论 :在不同致聋因素中 ,有的对单耳产生损伤作用 ,有的对双耳产生损伤作用。Objective:To investigate the latent influence on the contralateral ear when one ear was involves by different deaf elements. Method:TEOAE and DPOAE were recorded from contralateral ears with unilateral cochlear hearing loss,who were divided into 5 groups, group S 1,sudden deafness last within two months (9 ears),group S 2, sudden deafness last over one year or so(6 ears),Meniere's desease (13 ears M 1.M 2 )cochlear hearing loss of unknown etiology(7 ear,UNK),using ILO-96 analyzer system.Result:Response amplitude,wave reproducibility,band reproducibility of TEOAE in S 1,M 2 were significantly lower than normal values. Amplitude of DPOAE in S 1,M 2 were significantly lower than normal values. All record were the same with normal in S 2, M 1,UNK.Conclusion:In all sorts of deaf elements,some have an effect on binaural ears,the others have an effect on unilateral ear.
