慢性化脓性中耳炎鼓膜成形术的时机选择

摘要

Objective To explore the timing oi tympanoplasty in treatment of chronir otitis suppurative media, in order to provide basis for the clinical treatment. Methods A retrospective analysis of 50 cases( 56 ears )with hronir otitis suppurative media in our hospital Jun. 2009 to Jun. 2011 were divided into 7 groups arrording to the time of dry ear,and 8 ears were selected in earh group to rondurt tympanoplasty,the healing level of each patient was recorded and follow-up was done for 3 months to analyze the correlation between healing level and operation dry ear time. Results The highest hearing improvement alter tympanoplasty as treatment oi rhronir otitis suppurative media was after 2-4 months for dry ear by the fitting equation:Y - 12. 5567 +0. 19671x - 0. 03221 x2. Conclusion The optimal time oi tympanoplasty as treatment oi chronic otitis suppurative media was after 2-4 months for dry ear,which can increase the surressful rate and maximize the healing threshholds,thus improve patients life quality.%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.
