Description
Summary:The traditional canal wall down mastoidectomy (CWDM) procedure commonly has potential problems of altering the anatomy and physiology of the middle ear and mastoid. This study evaluated outcomes in patients who underwent modified canal wall down mastoidectomy (mCWDM) and mastoid obliteration using autologous materials. Our study included 76 patients with chronic otitis media, cholesteatoma, and adhesive otitis who underwent mCWDM and mastoid obliteration using autologous materials between 2010 and 2015. Postoperative hearing airbone gap and complications were evaluated. During the average follow-up of 64 months (range, 20 to 89 months), there was no recurrent or residual cholesteatoma or chronic otitis media. No patient had a cavity problem and anatomic integrity of the posterior canal wall was obtained. There was a significant improvement in hearing with respect to the postoperative air-bone gap (P
