【摘要】：[目的] 觀(guān)察開(kāi)放式乳突切除-鼓室成形術(shù)治療慢性化膿性中耳炎、膽脂瘤中耳炎的療效及術(shù)后聽(tīng)力的影響因素。 [方法] 回顧我院2008-2009年29例(29耳)行開(kāi)放式乳突根切除-鼓室成形術(shù)的手術(shù)病例,觀(guān)察手術(shù)療效,比較術(shù)前和術(shù)后的聽(tīng)力情況。其中23例行鐙骨頭“戴帽”加高成形(Ⅲa型),6例行鐙骨足板立柱加高成形(Ⅲb型)。膽脂瘤中耳炎13例,慢性化膿性中耳乳突炎(骨瘍型)16例。 [結(jié)果] 術(shù)后隨訪(fǎng)6個(gè)月-13個(gè)月,總干耳率為97%；無(wú)一例膽脂瘤復(fù)發(fā),術(shù)后再發(fā)穿孔2例；術(shù)后主觀(guān)聽(tīng)力有改善者22例,無(wú)改善者6例,變差者1例；29耳術(shù)前語(yǔ)言頻率區(qū)(0.5kHz. 1kHz.2kHz,聽(tīng)力級(jí),dBHL)氣導(dǎo)平均聽(tīng)閾(56.49±11.41)dB,骨導(dǎo)平均聽(tīng)閾(19.71±15.82)dB；術(shù)后氣導(dǎo)平均聽(tīng)閾(50.63±18.59)dB,較術(shù)前平均改善5.86dB,與術(shù)前相比t=3.161,P0.05,有統(tǒng)計(jì)學(xué)意義；術(shù)前氣骨導(dǎo)差(ABG) 15-56.67dB,平均(36.78±7.71)dB,術(shù)后ABG12.33-58.33平均_(29._89±9.79)dB,較術(shù)前平均縮小6.45dB,與術(shù)前相比較,t=3.487,P0.05,差異有統(tǒng)計(jì)學(xué)意義。 [結(jié)論] 開(kāi)放式乳突切除-鼓室成形術(shù)治療病變程度較嚴(yán)重的慢性化膿性中耳乳突炎和膽脂瘤中耳炎能徹底清除病灶,干耳率高,聽(tīng)力提高情況滿(mǎn)意。
[Abstract]:Objective: to observe the effect of open mastoidectomy and tympanoplasty on chronic suppurative otitis media and cholesteatoma. [methods] 29 cases (29 ears) of open mastoidectomy and tympanoplasty in our hospital from 2008 to 2009 were reviewed. Among them, 23 cases were treated with stapes head "cap" and (type 鈪，
