Transcanal endoscopic ear surgery for management of ossicular malformation: clinical outcomes of 17 cases.

In recent years, transcanal endoscopic ear surgery (TEES) is known as an innovative and minimally invasive surgery. To clarify the usefulness of TEES for the ossicular malformation, we performed a retrospective study. We examined cases of ossicular malformation performed using TEES at our hospital between April 2015 and April 2020. The hearing level results were countable for 16 cases. Post-operative hearing levels were significantly improved. Transient nausea, tongue paralysis, and taste disorders were observed; however, no other complications were observed. In 2015–2018, some of the cases required the assistance of a surgical microscope. In contrast, all the cases were performed by TEES after 2019 using a powered device to curve the canal. TEES requires considerable training, and the sensation of depth is difficult to acquire. However, this less invasive method is also helpful for ossicular malformation cases. [ABSTRACT FROM AUTHOR]

背景：近年来, 经耳道内窥镜耳部手术（TEES）被认为是一种创新的微创手术。 目的：为了阐明 TEES 对听骨畸形的有用性, 我们进行了一项回顾性研究。 材料和方法：我们检查了2015 年 4 月至 2020 年 4 月期间在我院接受 TEES 治疗听骨畸形的病例。 结果：共获得16例听力水平结果。术后听力水平明显提高。观察到一过性恶心、舌麻痹和味觉障碍；然而, 没有观察到其它并发症。 2015年至2018 年, 一些病例需要手术显微镜相助。相比之下, 在 2019 年之后, 所有病例均通过电动装置弯曲耳道, 接受 TEES。 结论及意义：TEES需要大量训练, 深度感难以获得。然而, 这种创伤性较小的方法有助于治疗听骨畸形病例。 [ABSTRACT FROM AUTHOR]
