摘要
对530例单耳慢性化脓性中耳炎患者的骨导听力损失情况进行总结和回顾性分析,探讨慢性化脓性中耳炎对耳蜗的损害.530例患者均未接受过耳科手术治疗,对侧耳为正常耳(作对照耳),其中男328例,女202例;年龄10~56岁,平均34岁;病程3个月~50年,平均20.19年.所有病例均采用Mad-sen—OB 822纯音测听仪在隔声室对患耳和正常耳进行听力测试,并对骨导听阈的平均值进行统计学处理,对影响骨导听力的因素做相关分析.所有患者中有334例(63.01%)发生骨导听力损害.0.5~4 kHz每个频率的骨导听力均有损失,主要损害在2~4 kHz的骨导听力损害程度与年龄、病程和病变程度有关.慢性化脓性中耳炎可以导致耳蜗损害,并以蜗底损害为著.
