Analysis on causes of wet ear after mastoidectomy［J］.

型鼓室成形术在开放式乳突根治术中的应用［J］。

Objective To study the occurrence mechanism and the clinical practice feasibility of cases of cavum tympani natural shaping after partial radical mastoidectomy.

目的 探讨部分慢性中耳炎乳突根治术后鼓室自然成形病例的发生机制和临床应用的可行性。

Methods A total of 18 radical mastoidectomy cases between June, 1996 and June, 2006 were analyzed, and the relationship between pathological characteristics, operation-performing features as well as dressing change after the operation and the phenomenon of tympanic membrane regeneration and healing were studied.

回顾性分析笔者1987年5月至2006年4月所做46例乳突根治手术及术后21例发生鼓室自然成形病例的资料，研究其病理特点、手术操作特点及术后换药特点等与术后鼓膜再生愈合现象的关系。

Methods One-stage mastoidectomy and tympanoplasty with ossicular chain reconstruction using postauricular musculo-periosteal-bone flap was completed in 47 cases（47ears） of cholesteatoma.

对47例（47耳）胆脂瘤中耳炎病人，在清除病变的同时一期行鼓室成形术，用耳后带蒂肌筋膜骨瓣修复听骨链进行听力重建。

One- stage mastoidectomy and tympanoplasty with ossicular chain reconstruction using postauricular musculo -periosteal- bone flap is a practical way to improve hearing and prevent cholesteatoma recurrence.

鼓室成形术中用耳后带蒂肌筋膜骨瓣修复听骨链行听力重建，能有效改善听力，降低胆脂瘤复发率，是一种较为实用的手术方法。

No any hearing decreased case was found compared with that in preoperation. Conclusion One- stage mastoidectomy and tympanoplasty with ossicular chain reconstruction using postauricular musculo -periosteal- bone flap is a practical way to improve hearing and prevent cholesteatoma recurrence.

鼓室成形术中用耳后带蒂肌筋膜骨瓣修复听骨链行听力重建，能有效改善听力，降低胆脂瘤复发率，是一种较为实用的手术方法。

Without external auditory meatus. And tympanum and ear bones development are undesirable, have audition obstacle.

无外耳道。且鼓室和听骨发育不良，有听力障碍。

Ear trauma ; Temporal bone fracture ; Tympanotomy ; Ossicle

耳外伤；颞骨骨折；鼓室探查术；听小骨

The acoustic sensibility was elevated and the descended abruptly in 3 ears after operation, the drum membrane separated with ossicles in 1 ear, the ossicle detached from oval window in 1 ear, the dislocation of malleus and stirrup in 1 ear.

术后听力提高后又突然下降3耳，其中1耳为重建听小骨与鼓膜分开，1耳为重建听小骨与卵圆窗分开，1耳为锤镫关节脱位，再次手术后听力均明显提高。2耳因胆脂瘤术后面瘫，CT示面神经管鼓室段缺损，再次手术后面瘫症状逐渐消失，但听力与术前相似。

Conclution On the basis of combination of closed and open techniques, the IBM technique with improvement strategies including the facial recess approach, the staging surgery, obliterating residual space, canal and mastoid plasty was adopted in mastoitympanoplasty. The IBM surgery is a reasionable choice for the otitis media and mastotoiditis with cholesteatoma or osteitis.

以乳突鼓室成形术的闭合技术和开放技术为出发点，在保留低位骨桥后对相关技术加以改进，综合运用面隐窝处理、缺损组织的填充与修复、分期手术、耳道生理形态的恢复与成形等现代耳显微外科技术，IBM手术效果良好。
