Maxillofacial Fibrous Dysplasia in Iran: a Case Series

Objective: To assess the prevalence of maxillofacial fibrous dysplasia in Iran, and to determine the relative involvement of the various head and neck bones, and symptoms and pattern of treatment.Patients and Methods: A retrospective study was conducted of the patients diagnosed and treated for maxillofacial fibrous dysplasia at the Imam Khomeini Complex Hospital and Amir Alam Hospital in Iran from 1999 to 2005.Results: Nineteen patients (14 men and 5 women) with a clinical diagnosis of fibrous dysplasia of the head and neck bones were enrolled. Patients had a mean age ± standard deviation of 18.3 ± 2.3 years. The most common site was the maxilla and the most common presentation was facial deformity. The incidence of the monostotic and polyostotic forms of fibrous dysplasia was the same. Surgery was done for all patients and 10 patients required more than 1 operation.Conclusion: Maxillofacial fibrous dysplasia in Iran shows a male preponderance. The maxilla is the most common site of lesion and facial deformity the most common presentation. Monostotic and polyostotic forms of fibrous dysplasia are equally prevalent. Surgery is the most frequent treatment.
