摘要

目的总结分析混合性聋的原因、听力重建术的方法及效果。方法回顾性分析32例混合性聋且行听力重建手术治疗患者的临床资料,分析其病因及根据不同病因所采取的听力重建手术方法,比较手术前后各频率气导听阈、骨导听阈、气骨导差及言语频率平均听阈,观察治疗效果。结果 32例患者中,慢性化脓性中耳炎15例、耳硬化症13例、Van der Hoeve综合征2例、先天性中耳畸形2例;听力重建术后言语频率气导听力提高15dB以上者26例,有效率为81.25%(26/32),全部患者术后言语频率气、骨导听力分别提高24.94±8.15dB和5.90±7.96dB,气骨导差缩小19.04±11.06dB(P<0.05)。术后0.25-4kHz气导听力较术前有不同程度提高(P<0.05),而手术前后8kHz气导听力无明显变化(P>0.05);术后骨导听力在1、2kHz处有提高(P<0.05),在2kHz处提高最明显。结论混合性聋多见于耳硬化症、慢性化脓性中耳炎、鼓室硬化等疾病。听力重建手术是治疗混合性聋的有效方法。
