Identifying epithelial borders in cholesteatoma surgery using narrow band imaging.

ABSTRACT:

Purpose

To quantify changes in the perceived epithelial border with narrow band imaging (NBI) and white light imaging (WLI) during cholesteatoma surgery and to objectify possible benefits of NBI in otology.

Methods

Perioperative digital endoscopic images were captured during combined approach tympanoplasty at our tertiary referral center using WLI and NBI (415 nm and 540 nm wavelengths). Sixteen otologic surgeon defined the epithelial borders within 16 identical WLI and NBI photos. Pixels of these selections were calculated to analyze the quantitative difference between WLI and NBI. A questionnaire also analyzed the qualitative differences.

Results

Sixteen otologic surgeons participated in the study. Stratified per photo, only two photos yielded a significant differen
