摘　　要：目的探讨并评价保留骨桥乳突鼓室成形术治疗慢性化脓性中耳乳突炎的临床效果。方法本文总结分析了2005年7月～2009年7月期间手术、随访至少12月的73例慢性化脓性中耳乳突炎者行保留骨桥鼓室成形术的病例,并对其临床效果进行评估。结果所有病例随访不少于12个月,干耳时间4～6周。移植鼓膜一期愈合66例。1例外耳道瘢痕增生狭窄,行外耳道成形术。术后纯音测听气骨导间距≤20 dB者占41.1%(30/73),21～30 dB者占30.1%(22/73),≥31 dB者占28.8%(21/73)。语频平均气导听阈15～55 dB HL,平均(27.2±8.9)dB HL,骨导听阈10～35 dB HL,平均(15.2±10.3)dB HL。结论术前颞骨CT的检查结果有助于手术方式的选择,对于乳突病变范围相对局限的病例选择完桥式鼓室成形术,在根除病灶的基础上保存或提高听力,是较佳的优化治疗选择。Objective To investigate and evaluate the effects of the operation of intact-bridge technique in treating chronic otitis media.Methods A retrospective review was performed of 73 cases undergoing an intact-bridge tympanomastoidectomy during the time interval from July,2005 to July,2009.Results The outcome of dry ear and well-epithelialized mastoid cavities was achieved about 4~6 weeks.After 1-year follow-up no recurrence occurred.The pure-tone average threshold improved by（27.2±8.9）dB HL after operation,and the mean air bone gap was elevated.Conclusion On the basis of combination of closed and open techniques,the IBM technique is an hoptimal cure strategy for chronic otitis media,which can not only remove the pathological changes thoroughly to prevent disease recurrence but also maximatily improve the hearing of the diseased ear.
