Objective: Cartilage is a rigid material that is highly resistant to infection and retraction and is tolerated well by the middle ear. The purpose of this study was to review retrospectively the results of cases of mastoid cavity obliteration with cartilage performed after canal wall down (CWD) mastoidectomy and to discuss the literature. Method: Of 983 patients who underwent surgery for chronic otitis media between January 2000 and June 2012, 54 patients who underwent CWD mastoidectomy plus mastoid cavity obliteration with cartilage and who were followed up regularly were selected from the database and invited for re-evaluation. All patients who came for a follow up after the invitation were examined and their data were evaluated retrospectively. Results: Thirty-five of the patients who accepted the invitation were included in the study. All of the patients in the study underwent mastoid cavity obliteration with conchal and/or tragal cartilage grafts. The duration of follow up ranged from 21 to 41 months (average, 27.3 months). Epithelization occurred in all patients with dry cavity, except one who had residual cholesteatoma and underwent revision surgery. Conclusion: The results of this study indicate that cartilage can be preferred for obliteration of mastoid cavity after CWD mastoidectomy.
