To identify factors that significantly influence myringoplasty success.
A retrospective study was performed of all adults and children who underwent myringoplasty from January 2005 to January 2010 in a teaching hospital. Outcome measures were tympanic membrane perforation closure and air-bone gap closure to within 20 dB HL. The factors assessed were the surgeon grade, pre-operative condition of the ipsilateral and contralateral middle ears, perforation site, perforation size, graft material, and whether simultaneous cortical mastoidectomy was performed. Factors with statistically significant effects were determined by logistic regression analysis.
In the adult group, the perforation site significantly influenced tympanic membrane closure (p = 0.016): anterior (p = 0.008) and subtotal (p = 0.017) sites had the greatest influence. None of the factors proved to have a significant influence on tympanic membrane closure in the paediatric group.
There was a significant association between perforation site and tympanic membrane perforation closure in adults. Anterior and subtotal perforations had a significantly reduced closure rate.
确定显著影响鼓膜成形术成功的因素。
对2005年1月至2010年1月在一家教学医院接受鼓膜成形术的所有成人和儿童进行回顾性研究。观察指标为鼓膜穿孔闭合以及气骨导差缩小至20dB HL以内。评估的因素包括外科医生级别、同侧和对侧中耳的术前状况、穿孔部位、穿孔大小、移植物材料以及是否同期进行了皮质骨乳突切除术。通过逻辑回归分析确定具有统计学显著影响的因素。
在成人组中，穿孔部位对鼓膜闭合有显著影响（p = 0.016）：前部（p = 0.008）和大部分穿孔（p = 0.017）影响最大。在儿童组中，没有因素被证明对鼓膜闭合有显著影响。
成人的穿孔部位与鼓膜穿孔闭合之间存在显著关联。前部和大部分穿孔的闭合率显著降低。
