Results of endoscopic cartilage tympanoplasty procedure with limited tympanomeatal flap incision

Abstract

Objective: The aim of this study was to evaluate the outcomes of this minimally invasive tympanomeatal incision technique performed during endoscopic transcanal cartilage tympanoplasty.

Study design: Prospective clinical study.

Methods: Eighty-seven patients (87 ears) who had TM perforation with noncomplicated COM were included. All of the patients were operated with the endoscopic transcanal cartilage tympanoplasty technique. All of the data were prospectively collected. These included demographic data, date of the surgery, preoperative and postoperative pure-tone audiometry (PTA), localization of TM perforation and graft healing success.

Results: Mean follow-up time was 14.76 ± 4.32 months. Graft-healing rate was 100%. Mean air bone gap level improvement (dB HL) at 0.5, 1, 2 and 4 kHz were 13.87 ± 7.30 dB HL, 9.09 ± 7.59 dB HL, 9.74 ± 6.40 dB HL and 7.46 ± 6.37 dB HL, respectively. At all frequencies, there was significant difference between pre and postoperative mean air bone gap levels (p < .05). There was no significant correlation between the postoperative mean air bone gap level improvement and the localization of the perforation (p > .05).

Conclusions: Endoscopic ear surgery has successful surgical outcomes with low complication rates. In this study, the outcomes of limited tympanomeatal flap incision was discussed. It is suggested that this technique is reliable with good hearing results with low postoperative complications rates.

目的：本研究的目的是评估在内镜下经耳道软骨鼓膜成形术中进行的微创性鼓室切开术的结果。

研究设计：前瞻性临床研究。

方法：87例（87只耳）患有带轻微COM的TM穿孔患者被纳入研究。所有患者均采用内镜经耳道软骨鼓膜成形术进行手术。所有数据都被预先收集。这些包括人口学资料、手术日期、术前和术后纯音听力测量（PTA）、TM穿孔位置和皮植治疗成功资料。

结果：平均随访时间为14.76 ± 4.32个月。皮植愈合率为100%。 0.5、1、2和4 kHz的平均空气骨隙水平改善（dB HL）分别为13.87 ± 7.30 dB HL、9.09 ± 7.59 dB HL、9.74 ± 6.40 dB HL和7.46 ± 6.37 dB HL。在所有频率下, 术前和术后平均空气骨隙水平差异有统计学意义（p <0.05）。术后平均空气骨隙水平改善与穿孔位置无显著相关性（p> 0.05）。

结论：内镜耳手术具有成功的结果, 并发症发生率较低。在本研究中, 讨论了有限性鼓膜皮瓣切开术的结果。我们认为该技术可靠, 听觉效果良好, 术后并发症率低。
