[Fibrous dysplasia in the head and neck region: a report of three cases].

Fibrous dysplasia is a benign process in which bone expands due to abnormal development of fibrous tissue. Involvement of single or multiple bones may occur. Common sites of involvement in the head and neck region are the maxilla and the mandible. Temporal bone involvement is rare. We report three patients with fibrous dysplasia, in whom the temporal bone (female, age 35 years) and the maxilla (male, age 17 years; female, age 20 years) were affected. The former underwent mastoidectomy, while the latter two patients underwent mass excision with lateral rhinotomy. No recurrences were detected within long-term follow-ups.
