To report a novel tympanoplasty modification for anterior tympanic membrane perforation closure.
A prospective study on 13 patients who underwent inferior tympanoplasty between December 2008 and May 2011 was carried out. In our technique, an inferior rather than a posterior flap is raised and the graft is laid from the inferior direction to obtain better access to the anterior part of the tympanic membrane perforation and provide better support.
A total of 13 patients underwent the novel inferior tympanoplasty technique with a mean age of 33 years. Six patients had undergone tympanoplasties and/or mastoidectomies in the past, 3 in the contralateral ear. A marginal perforation was observed in 3 cases, total perforation in 2 and subtotal in 1 case. The mean preoperative pure-tone average was 40.4 dB (10 to 90 dB), compared to 26.5 dB (10 to 55 dB) postoperatively. All perforations were found to be closed but one (92.3% success rate).
The inferior tympanoplasty technique provides a favorable outcome in terms of tympanic membrane closure and hearing improvement for anterior perforations, even in difficult and complex cases. It is based on a well-known technique and is easy to implement.
报告一种用于前鼓膜穿孔闭合的新型鼓室成形术改良方法。
对 2008 年 12 月至 2011 年 5 月期间接受下鼓室成形术的 13 例患者进行了前瞻性研究。在我们的技术中,掀起的是下鼓室瓣而非后鼓室瓣,移植物从下方放置,以更好地接近鼓膜穿孔的前部分,并提供更好的支撑。
共有 13 例患者接受了新型下鼓室成形术,平均年龄为 33 岁。6 例患者既往有过鼓室成形术和/或乳突切除术,3 例患者对侧耳有过。3 例观察到边缘性穿孔,2 例完全性穿孔,1 例部分性穿孔。术前纯音平均听阈为 40.4dB(10 至 90dB),术后为 26.5dB(10 至 55dB)。所有穿孔均闭合,但有 1 例(92.3%的成功率)未闭合。
下鼓室成形术技术为前穿孔的鼓膜闭合和听力改善提供了良好的结果,即使在困难和复杂的情况下也是如此。它基于一种众所周知的技术,易于实施。
