Osteoma of the internal auditory canal

Objective: To review presenting symptoms and illustrate management options for this uncommon lesion. Design: Case series and literature review. Setting: Tertiary referral center. Patients: Three cases of osteoma of the internal auditory canal are presented. Additional cases from the literature, diagnosed by radiographic appearance or gross description, are included for comparison. Main Outcome Measure: Response of clinical symptoms. Results: Presenting symptoms are highly variable. Available reports do not adequately define the natural history of the lesion. Conclusion: The lack of a consistent presentation despite a similar radiographic appearance suggests that the osteoma is often an incidental finding.
