Abstract
Fully endoscopic ear surgeries are done in several centres for mucosal (non cholesteatomatous) otitis media. It is also being incorporated in cholesteatoma surgeries where the disease is presumed to be limited. Often the true extent of cholesteatoma is revealed only intraoperatively, necessitating microscope assistance and an on table conversion to a microscope assisted endoscopic ear surgery. This paper analyses the role of preoperative diffusion weighted MRI in cholesteatoma and whether preoperatively patients with cholesteatoma can be offered totally endoscopic transcanal ear surgery.
Keywords-Chronic otitis media, cholesteatoma, fully endoscopictympanomastoidectomy, Microscope assisted endoscopictympanomas-toidectomy,diffusion restricted MRI
