分期鼓室成形手术的疗效观察

Two terms tympanoplasty in chronic suppurative otitis media

目的 :探讨分期鼓室成形手术治疗慢性化脓性中耳炎的疗效。方法 :对 36例 (36耳 )本病患者 1期手术行乳突根治术 ,其中 2 6耳为开放式术式 ,10耳为关闭式术式。次期手术主要连接听骨链 ,其中 型 2耳 , 型 2 5耳 , 型 5耳 ;另 4耳无法成形者则行单纯乳突根治术。结果 :36例中 32例成功 ,4例失败。结论 :分期鼓室成形手术可挽救大部分慢性化脓性中耳炎患者的术后听力 ,在中耳粘膜增厚、粘膜缺损较小或术前咽鼓管不通的病例可获得较好的效果 ;但对中耳粘膜缺损较大的病例效果较差 ;
