Otoendoscopy in the Office and Operating Room.

Since its introduction into the field of otology in 1967 endoscopes are gaining acceptance in evaluation and treatment of middle ear disease. Endoscopes offer a wide field view enabling looking "around the corner" with reduced need for soft tissue and bone removal. Outcomes of middle ear surgery for cholesteatoma and need for second-look procedures are improving because of the addition of endoscopic evaluation. Trainee education using the endoscope improves knowledge of middle ear anatomy. The portability of the endoscopic unit allows performing ear surgery in remote locations.
