INTRODUCTION: Fibrous dysplasia is benign tumor of the craniofacial skeleton that primarily affects young patients. It is characterized by the progressive growth of benign fibrous tumors with resulting functional and aesthetic deformities. This study assesses the clinical and prognostic features in patients with fibrous dysplasia who underwent surgical treatment at our institution.
METHODS: Retrospective analysis of 19 patients with craniofacial fibrous dysplasia, treated between January 1997 and December 2011 with bone remodeling and surgical resection. We also review the literature regarding fibrous dysplasia.
RESULTS: Patients ranged between 8-65 years old, with a mean age of 21.75 years. Ten patients (52.7%) were women. The polyostotic form was predominant and present in15 cases (78.9%). The sphenoid, ethmoid, and frontal bones were most commonly involved in the polyostotic form and the mandibular and zygomatic bones were most commonly involved in the monostotic form. The main complaint was asymmetry of the face. One patient developed decreased visual acuity. Treatment was based on surgical resection and graft reconstruction in the localized form of the disease, and bone abrasion and remodeling in the polyostotic form. Intracranial access was necessary in only one case (5.2%) where the optic nerve was compressed. Repeat surgical treatment due to recurrent tumor growth was necessary in three patients. The only complication occurred in a patient who developed lagophthalmos and epicanthus postoperatively after undergoing surgery using infraorbital access. No other complications occurred during short- and long-term follow-up. Functional preservation and facial contour recovery outcomes were satisfactory.
CONCLUSION: Our experience, along with that of other investigators, demonstrates that surgery is effective in treating selected cases of craniofacial fibrous dysplasia.
