Endoscopes, despite being called “cold light” instruments, produce heat when introduced to the middle ear. The heat tends to accumulate in  the small volume, poorly ventilated middle ear. Until now, no study has reliable described what temperature changes happen during endoscopic ear surgery. Since the risk of thermal damage remains a major concer of of ear endoscopists, the International Working Group on Endoscopic Ear Surgery published recommendations in order to reduce this type of injury. The goal of this publication is to evaluate the IWGEES recommendations and conclude which are well founded.

– Study design: prospective
