目的 :探讨仅存单耳听力胆脂瘤根治和听力重建的可行性。方法 :回顾分析 1990～ 2 0 0 0年间在我院手术的 15例仅存单耳听力的传导性耳聋手术后的听力改善情况。鼓室成形Ⅲ型 6耳 ,Ⅰ型 5耳 ;乳突或上鼓室根治 4耳 ,其中 3耳同时行鼓室成形Ⅲ型 ,1耳仅作复发的胆脂瘤清除。结果 :15耳均干耳。除 3耳听力不变或气骨导差缩小不足 10dB外 ,余 12耳 (80 %)均有不同程度的提高。缩小 30dB以上的 2耳 ,2 0dB以上 6耳 ,10dB 4耳 ,P <0 .0 1。无一耳发生术耳感音功能下降。结论 :对于仅存单侧听力的胆脂瘤型中耳炎根治和听力重建是可行的 ,但需加倍小心谨慎 ,动作要轻柔 ,最大程度地减少对内耳的扰动 ,并由经验丰富的医师担当手术。
Objective: To investigate the feasibility of radical prostatectomy and hearing reconstruction of the only single-ear hearing-enhancing cholesteatoma. Methods: A retrospective analysis of 15 cases of surgery in our hospital from 1990 to 2000 only surviving single hearing hearing-induced hearing loss after surgery. Tympanic cavity type Ⅲ 6 ears, Ⅰ type 5 ears; mastoid or upper tympanic radical 4 ears, of which 3 ears at the same time tympanic type Ⅲ, 1 ear only for recurrent cholesteatoma. Results: 15 ears are dry ears. Except for hearing loss of 3 ears or less than 10dB reduction of air conduction, more than 12 ears (80%) were improved to some extent. Narrowed more than 30dB 2 ears, 20dB more than 6 ears, 10dB 4 ears, P <0. No ear surgery ear sensor function decreased. Conclusions: Radical cholecystitis and cholecystitis with cholesteatoma only exist on one side. However, we should be more cautious and act gently to minimize the disturbance to the inner ear, which is performed by an experienced physician.
