Otoendoscopy in Cholesteatoma Surgery of the Middle Ear

Abstract

This study confirms the real value of otoendoscopy in the surgical management of cholesteatomas of the middle ear. It belongs entirely to the minimally invasive surgical procedures, while significantly reducing the frequency of open tympanoplasty and recourse to posterior tympanotomy and offering excellent access to numerous lesions by the transmeatal approach. Analysis using otoendoscopy reduces the incidence of residual cholesteatomas by identifying lesion extensions that are overlooked under otomicroscopy. Nevertheless, some residual cholesteatomas persist at the second stage of surgery. The quality of excision under otoendoscopy constitutes an important parameter in the decision regarding revision surgery. By targeting the at-risk regions where a residual lesion was discovered, it allows the control scanner to be read with greater accuracy, thus facilitating the decision on whether to perform surgical exploration.
