摘要: 目的: 探讨耳蜗电图(ECochG)对OSAHS患者耳蜗及听神经损伤评估的价值。方法: 对31例(62耳)OSAHS患者(中度5例,重度26例)和28例(56耳)健康成年人行ECochG检测,分别测量2组中AP潜伏期、AP振幅及SP/AP振幅比,比较组间结果。结果: OSAHS组、对照组AP潜伏期分别为(1.76±0.28)ms、(1.52±0.15) ms,差异有统计学意义(P<0.05);OSAHS组、对照组AP振幅分别为(0.99±1.00)μV、(1.23±0.57)μV,差异有统计学意义(P<0.05);SP/AP振幅比分别为0.32±0.16、0.28±0.07,2组比较差异无统计学意义(P>0.05)。19%的OSAHS患者SP/AP振幅比异常增高。结论: ECochG可发现中度及重度OSAHS患者耳蜗及听神经近耳蜗段的损伤。

Abstract: Objective: To investigate the values of electrocochleograph(ECochG)in patients with OSAHS.Method: ECochG was performed in 31 (62 ears) OSAHS patients (moderately 5 cases, severely 26 cases) and 28 healthy adults (56 ears). AP latency,AP amplitude and SP/AP were measured and analyzed.Result: There was no difference between the two groups in SP/AP amplitude ratio(P>0.05) while both AP latency(P<0.05) and AP amplitude(P<0.05) were significantly different.Conclusion: ECochG can confirm the damage of cochlear and auditory nerve near the cochlear segment in patients with moderate to severe OSAHS.-
