Cochlear Implantation in Chronic Otitis Media with and without Cholesteatoma: Surgical Considerations and Auditory Outcomes.

Postoperative complications like device failure and skin breakdown are increased in cases of COM compared to standard CI surgeries. However, that increase is not associated with staging the surgeries, presence or absence of cholesteatoma, and type of ear surgery performed. It is advocated to close the external ear canal and eustachian tube without mastoid obliteration in the presence of a radical mastoidectomy cavity, which will decrease the postoperative complication rates and allow for radiological follow-up with computed tomography for the possibility of cholesteatoma recurrence. The auditory benefits of CI in patients with and without COM are comparable.
