Surgical Treatment of Craniomaxillofacial Fibrous Dysplasia

Abstract

Fibrous dysplasia (FD) is a tumor-like growth that consists of replacement of the medullary bone with fibrous tissue, causing the expansion and weakening of the areas of bone involved. The most commonly affected bones are facial bones, causing a number of facial cosmetic and functional problems. From December 2008 to July 2012, 10 patients with craniomaxillofacial fibrous dysplasia were treated by conservative resection and local recontouring. The patients were followed up yearly, with an average of 3 years; the longest follow-up period was 5 years. All the 10 patients received appropriate treatment and histopathological examinations were performed to confirm the diagnosis of FD. Four patients with zygoma involved had received partial zygoma osteoectomy and 2 patients received mandibular partial osteoectomy. Average time of follow-up was 3 years, with a range from 1 to 5 years, and all patients obtained satisfactory aesthetic and functional results. In most patients, a conservative surgery will achieve good functional and aesthetic results. For patients with mild symptoms, the aesthetic effect should be given priority while for the heavier patients the restoration of function and aesthetic effects should all be taken into account.
