Endoscopic 'second look' mastoidoscopy to rule out residual epitympanic/mastoid cholesteatoma.

Endoscopic mastoidoscopy is ideally suited for patients who have undergone an intact canal wall mastoidectomy for primary acquired cholesteatoma confined to the epitympanum and mastoid. The use of an endoscopic technique significantly decreases the morbidity of the second-look procedure. Visualization of the pertinent anatomy can be reliably, quickly, and safely accomplished.
