Objectives. The purpose of this study was to inspect the clinical characteristics, surgical approaches, functional preserva- tion, and complications of petrous bone cholesteatoma and to propose appropriate surgical approaches based on long-term follow-up cases and previous reports in the literature. Methods. The medical records of 31 patients who underwent surgery for petrous bone cholesteatoma between 1990 and 2011 at two tertiary referral hospitals were retrospectively analyzed with regard to the classification, type of surgical approach, preservation of facial and auditory function, and recurrence. Results. Of 31 cases, 16 were supralabyrinthine (class I), 1 was infralabyrinthine-apical (class III), 13 were massive (class IV), and 1 was apical (class V). Facial nerve palsy was found in 35.5% of the cases (11 cases). Hearing was preserved in 11 of 22 patients who had better than a 50-dB hearing level of bone conduction pure tone average preoperatively. Preoperative hearing was preserved in only four of the patients in class I (supralabyrinthine). Facial function was pre- served or improved in 29 patients (93.5%). Conclusion. Complete removal of cholesteatoma of petrous bone can be achieved by choosing the appropriate approach based on location and extent. Facial function was preserved postoperatively in most reviewed cases. Auditory func- tion could not be preserved postoperatively in some cases, but preserving residual hearing levels can be accomplished mostly in supralabyrinthine cholesteatomas with the appropriate surgical approach.
