Objective evaluation, using computed tomography, of round window access for cochlear implantation.

ABSTRACT:

Objective

The aim of this study was to determine optimal radiological parameters for assessment of the round window approach in cochlear implantation surgery.

Materials and methods

Patients undergoing cochlear implantation at the Department of Otolaryngology in Szczecin, between 2015 and 2022 inclusive, were eligible for the study. Radiological assessments were performed according to eight parameters (seven proposed in the literature) and visibility clinical assessments were made intra-operatively on a scale of 1 to 5 (1 - not visible, 5 - fully visible). Visibility assessments of the round window niche (RWN) and round window membrane (RWM) allowed the difference (RWN minus RWM) to be used as a clinical assessment of the size of the overhang over the round window.
