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

Acta Otolaryngol. 2022 Feb;142(2):154-160. doi: 10.1080/00016489.2022.2039406. Epub 2022 Mar 2.


Background: In recent years, transcanal endoscopic ear surgery (TEES) is known as an innovative and minimally invasive surgery.

Aims: To clarify the usefulness of TEES for the ossicular malformation, we performed a retrospective study.

Material and methods: We examined cases of ossicular malformation performed using TEES at our hospital between April 2015 and April 2020.

Results: 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.

Conclusions and significance: 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.

Keywords: TEES; Transcanal endoscopic ear surgery; ossicular malformation.
