Results of endoscopic middle ear surgery for cholesteatoma treatment: a systematic review.

Traditional surgery for cholesteatoma of the middle ear is performed by microscopic approaches. However, in recent years endoscopic instrumentation, techniques and knowledge have greatly improved, and in our opinion endoscopic surgical techniques will gain increasing importance in otologic surgery in the future. The aim of this study was to focus on outcomes obtained using endoscopic surgery for the treatment of middle ear cholesteatoma. A systematic review of the literature was performed. A total of 7 articles comprising 515 patients treated exclusively with endoscope or with a combined technique were found. During post-surgical follow-up, 48 (9.3%) patients showed a residual or recurrent pathology. Despite the small number of patients analyzed in our review, the outcomes of this technique appear to be promising. In particular, concerning the rates of recurrences and residual disease, endoscopic middle ear surgery appears to guarantee similar results in comparison to classic microscopic approaches with the advantage of performing minimally invasive surgery.
