Abstract

Objectives: The study objective is to describe a new stapedotomy and its short-term hearing results.

Study design: Prospective study.

Setting: Tertiary referral center.

Methods: From February to June 2024, was conducted a study on the first 13 total columellar ossiculoplasties with footplate fenestration performed in patients with otosclerosis. In all patients, we used the new semisynthetic TORP (NSSTORP). Its base was positioned on the footplate hole rim, and its head was positioned under the eardrum. The author named this new surgical technique "tympano-stapedotomy." For all patients, the last audiometric control considered was performed on September 2024. The mean follow-up was of 5 months.

Main outcome measures: Percentage of patients achieving an air-bone gap (ABG) of less or equal to 10 and 20 dB.

Results: At the end of follow-up, the air-conduction pure-tone average (PTA) improved from a mean of 62.1 dB (SD = 18.9) preoperatively to a mean of 42.8 dB (SD = 13.1) postoperatively: an average of 19.3 dB gain. The mean preoperative ABG was 30.9 dB (SD = 9.2), and the mean postoperative ABG was 11.6 dB (SD = 6.4): an average of 19.2 dB gain. The postoperative ABG of ≤10 was achieved in 38.5% (n = 5), of ≤15 in 77% (n = 10), and of ≤20 in 100% (n = 13).

Conclusion: The NSSTORP has a minimal technical challenge for building and placement. The tympano-stapedotomy bypasses the ossicular chain and most of the challenge maneuvers and complications associated with it. Its hearing results are good.

新型镫骨切开术：新型半合成TORP听骨链旁路。

目的：描述一种新的镫骨切开术及其短期听力效果。研究设计：前瞻性研究。单位：三级转诊中心。方法：对2024年2月~ 6月收治的13例耳硬化症患者行足部开窗全小柱骨成形术进行回顾性研究。所有患者均采用新型半合成TORP （NSSTORP）。其底座位于底板孔边缘，头部位于耳膜下方。作者将这种新的手术技术命名为“鼓室-镫骨切开术”。所有患者最后一次考虑的听力控制是在2024年9月进行的。平均随访5个月。主要结局指标：达到小于或等于10和20 dB的气骨间隙（ABG）的患者百分比。结果：随访结束时，空气传导纯音平均（PTA）由术前平均62.1 dB （SD = 18.9）改善至术后平均42.8 dB (SD = 13.1)，平均增益19.3 dB。术前平均ABG为30.9 dB (SD = 9.2)，术后平均ABG为11.6 dB (SD = 6.4)，平均增益19.2 dB。术后ABG≤10的有38.5% (n = 5)，≤15的有77% (n = 10)，≤20的有100% （n = 13）。结论：NSSTORP在建造和放置方面具有最小的技术挑战。鼓室-镫骨切开术绕过听骨链，大多数的挑战操作和并发症与之相关。其听力效果良好。
