Scutum reconstruction technique and classification in endoscopic middle ear cholesteatoma surgery

Abstract

Background

Endoscopy has been increasingly used in middle ear cholesteatoma surgery. It can increase the proportion of canal wall up (CWU) surgery and effectively control the recurrence and residual rates. However, there is a lack of systematic description on scutum reconstruction technique in endoscopic middle ear cholesteatoma surgery.

Objective

The technique and classification of scutum reconstruction in endoscopic cholesteatoma surgery were proposed, and the outcomes were preliminarily evaluated.

Methods

According to the development of mastoid and the way of hearing reconstruction, the reconstruction of scutum was classified into three types. The rates of residual and recurrence and hearing outcomes were observed and analyzed.

Results

A total of 57 patients underwent endoscopic cholesteatoma surgery, all of which were CWU surgery. The reconstruction of the scutum was performed using tragal cartilage according to three types. The residual of cholesteatoma was observed in three cases. The recurrence of cholesteatoma and retraction pocket was detected in two cases and five cases, respectively. Postoperative hearing results were generally satisfied in all three types of surgeries.

Conclusion

The technique of scutum reconstruction in endoscopic cholesteatoma surgery in this work can effectively control the recurrent disease after CWU surgery.

Chinese abstract

背景：内窥镜检查已越来越多地用于中耳胆脂瘤手术。它可以增加耳道扩张（CWU）手术的比例, 并有效控制复发和残留率。但是, 关于在内镜耳胆脂瘤手术中应用的盾片重建技术缺乏系统的描述。

目的：提出内窥镜胆脂瘤手术中的盾片重建技术及分类方法, 并对其效果进行初步评估。

方法：根据乳突的发展情况和听力重建的方式, 盾片重建分为三种类型。观察和分析残留率、复发率以及听力结果。

结果：共57例接受内镜胆脂瘤手术, 全部为CWU手术。根据三种类型, 使用骨软骨进行了盾片的重建。 3例观察到胆脂瘤残留。胆脂瘤的复发和缩袋分别在2例和5例中发现。在所有三种类型的手术中, 术后听力结果普遍令人满意。

结论：本研究中, 内镜胆脂瘤手术中的盾片重建技术可以有效地控制CWU手术后的疾病复发。
