Abstract

A review was made of 128 canal wall-down tympanoplasties for chronic otitis media with cholesteatoma. The cholesteatoma was found in the attic (82.4%), antrum (71.7%), mastoid (45.8%), and mesotympanum (35.8%). In 89.1% of cases there was ossicular chain injury. In 39%, the ossicular chain was partially reconstructed (modified canal wall-down tympanoplasty). After one year, 84.4% of the operated ears were safe, dry and self-cleaning. The others (15.6%) had postoperative otorrhea. Canal wall-down modified mastoidectomy achieved closure of the air-bone gap from 40 to 24 dB (p < 0.001).

摘要

对128例慢性胆脂瘤型中耳炎行开放式鼓室成形术的病例进行了回顾性研究。胆脂瘤见于上鼓室（82.4%）、鼓窦（71.7%）、乳突（45.8%）和中鼓室（35.8%）。89.1%的病例存在听骨链损伤。39%的病例听骨链进行了部分重建（改良开放式鼓室成形术）。术后1年，84.4%的术耳安全、干燥且能自我清洁。其余（15.6%）有术后耳漏。开放式改良乳突根治术使气骨导差从40 dB缩小至24 dB（p<0.001）。
