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 present ed. Additional cases from the literature, diagnosed by radiographic appeara nce 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 radiogr aphic appearance suggests that the osteoma is often an incidental finding.
