【摘要】:[目的] 观察开放式乳突切除-鼓室成形术治疗慢性化脓性中耳炎、胆脂瘤中耳炎的疗效及术后听力的影响因素。 [方法] 回顾我院2008-2009年29例(29耳)行开放式乳突根切除-鼓室成形术的手术病例,观察手术疗效,比较术前和术后的听力情况。其中23例行镫骨头“戴帽”加高成形(Ⅲa型),6例行镫骨足板立柱加高成形(Ⅲb型)。胆脂瘤中耳炎13例,慢性化脓性中耳乳突炎(骨疡型)16例。 [结果] 术后随访6个月-13个月,总干耳率为97%;无一例胆脂瘤复发,术后再发穿孔2例;术后主观听力有改善者22例,无改善者6例,变差者1例;29耳术前语言频率区(0.5kHz. 1kHz.2kHz,听力级,dBHL)气导平均听阈(56.49±11.41)dB,骨导平均听阈(19.71±15.82)dB;术后气导平均听阈(50.63±18.59)dB,较术前平均改善5.86dB,与术前相比t=3.161,P0.05,有统计学意义;术前气骨导差(ABG) 15-56.67dB,平均(36.78±7.71)dB,术后ABG12.33-58.33平均_(29._89±9.79)dB,较术前平均缩小6.45dB,与术前相比较,t=3.487,P0.05,差异有统计学意义。 [结论] 开放式乳突切除-鼓室成形术治疗病变程度较严重的慢性化脓性中耳乳突炎和胆脂瘤中耳炎能彻底清除病灶,干耳率高,听力提高情况满意。
