慢性化脓性中耳炎鼓膜成形术的时机选择

目的探讨慢性化脓性中耳炎鼓膜成形术的时机选择,为临床治疗提供依据。方法选择2009年6月至2011年6月我院收治的慢性化脓性中耳炎患者50例(56耳),根据干耳时间,选择7个组段干耳时间,每组干耳时间选择8耳行鼓膜成形术,记录每例患者的听力水平,并随访观察3个月,分析治疗后听力水平与干耳时间的关系。结果通过拟合最佳方程Y^=12.5567+0.19671x-0.03221x2,发现鼓膜成形术选择在干耳时间2～4个月,听力水平提高最高。结论慢性化脓性中耳炎鼓膜成形术的最佳时机选择在干耳时间2～4个月能够提高手术成功率,使听力阈值最大,患者生活质量得到改善。

Timing of Tympanoplasty in Treatment of Chronic Otitis Suppurative Media

Objective To explore the timing of tympanoplasty in treatment of chronic otitis suppurative media,in order to provide basis for the clinical treatment.Methods A retrospective analysis of 50 cases(56 ears)with hronic otitis suppurative media in our hospital Jun.2009 to Jun.2011 were divided into 7 groups according to the time of dry ear,and 8 ears were selected in each group to conduct tympanoplasty,the hearing level of each patient was recorded and follow-up was done for 3 months to analyze the correlation between hearing level and operation dry ear time.Results The highest hearing improvement after tympanoplasty as treatment of chronic otitis suppurative media was after 2-4 months for dry ear by the fitting equation:Y^=12.5567+0.19671x-0.03221x2.Conclusion The optimal time of tympanoplasty as treatment of chronic otitis suppurative media was after 2-4 months for dry ear,which can increase the successful rate and maximize the hearing threshholds,thus improve patients life quality.
