It is often reported that the repair of subtotal perforations is less successful than that of smaller perforations, mainly because it is technically more difficult. The author's surgical technique for subtotal perforations is presented and the results compared with that of myringoplasty for smaller perforations. The study shows that subtotal perforations are associated with a higher incidence of abnormal middle ear mucosa (chi 2 = 11.75, d.f. = 2) and damage to the malleus (chi 2 = 5.60, d.f. = 1) than smaller perforations. However, the success rate of subtotal perforation closure (92.5%) is as good as the closure rate for smaller perforations (94.1%). It is concluded that the size of the perforation is not a major factor in determining whether the graft will be successful in myringoplasty.
经常有报道称，较大穿孔的修复成功率低于较小穿孔，主要是因为其技术难度更大。本文介绍了作者针对较大穿孔的手术技术，并将结果与较小穿孔鼓膜成形术的结果进行了比较。研究表明，与较小穿孔相比，较大穿孔伴有中耳黏膜异常的发生率更高（卡方检验=11.75，自由度=2），锤骨损伤的发生率也更高（卡方检验=5.60，自由度=1）。然而，较大穿孔闭合的成功率（92.5%）与较小穿孔的闭合率（94.1%）相当。得出的结论是，穿孔大小并非决定鼓膜成形术中移植物是否成功的主要因素。
