Can endoscopic ear surgery replace microscopic surgery in the treatment of acquired cholesteatoma? A contemporary review.

Acquired cholesteatoma leads to significant morbidities while current surgical options remain a challenge. The principles of surgery include complete removal of disease, prevention of recurrence, and restoration of hearing function when possible. Traditionally, this has been performed using microscopes; however, a novel technique using endoscopes offers a new perspective on our understanding of anatomy, pathogenesis and surgical approaches. In recent years, various studies have demonstrated good outcomes with transcanal endoscopic ear surgery (EES) in cholesteatoma surgery. Nevertheless, the use of EES is not universal and remains controversial due to the efficacy of microscopes, specific limitations of endoscopes and the need to learn new skills. This review focuses on recent advances in EES for the treatment of acquired cholesteatoma, benefits, current challenges, and a discussion on the indications and contraindications of EES.Copyright © 2020
