INTRODUCTION To reduce incidence of residual cholesteatoma following ear surgery; and to reduce the need for second look "open" mastoidectomy using endoscopic mastoidotomy. Ten-year retrospective chart review of 249 primary cholesteatoma cases (1994-2004) with a minimum follow-up of two years. The first objective was to evaluate the effectiveness of otoendoscopy in reducing the incidence of "ch...

BACKGROUND The surgical management of cholesteatoma is a controversial issue, particularly regarding intact-canal-wall mastoidectomy (ICWM) versus canal-wall-down mastoidectomy (CWDM). The current experiment compared the quality of visualization in different middle ear structures using ICWM with otoendoscopy with findings of CWDM by microscopy. MATERIALS AND METHODS The patients diagnosed wit...

Materials and Methods: In a prospective, controlled animal study, a poly-l-lactide stent was implanted via a transbullar approach in one Eustachian tube (ear implanted was randomly selected) of five adult female chinchillas. The other ear served as a matched control. Otoendoscopy was performed at baseline to rule out pre-existing disease. Animals were sacrificed at varying times up to 26 weeks ...
