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.
