目的 :分析鼓室成形术的效果。方法 :回顾性分析近 10年 2 80例 (32 4耳 )慢性化脓性中耳炎患者鼓室成形术 (Ⅰ型和Ⅱ型 )的鼓膜愈合及听力恢复情况。结果 :鼓膜愈合率 90 .1% ,听力提高 15dB以上者 75 % ,气骨距 <2 0dB者 74.1% ,听力达应用水平者 6 0 .5 %。不同移植材料之间成活率无显著性差异 (P >0 .0 5 ) ;鼓膜穿孔大小对疗效无明显影响 (P >0 .0 5 ) ;静止期与移植物成活关切密切 (P <0 .0 5 )。结论 :在正确掌握手术适应证和手术时机及精湛手术技巧进行鼓室成形术 ,可达到清除病灶 ,修复鼓膜及提高听力的目的。
Objective: To analyze the effect of tympanoplasty. Methods: The tympanoplasty and hearing recovery of tympanoplasty (type Ⅰ and type Ⅱ) in 280 patients (32 4 ears) with chronic suppurative otitis media in recent 10 years were analyzed retrospectively. Results: The healing rate of tympanic membrane was 90.1%, the hearing ability was increased above 15dB, 75%, the air space was less than 20dB, 74.1%, and the hearing level was 60.5%. There was no significant difference in the survival rate between different graft materials (P> 0.05). The tympanic membrane perforation size had no significant effect on the curative effect (P> 0.05), and the quiescent period was closely related to the graft survival (P <0. 0 5). Conclusion: The correct understanding of surgical indications and timing of surgery and exquisite surgical techniques for tympanoplasty, can achieve the removal of lesions, repair tympanic membrane and improve hearing purposes.
