Free fibula flap mandible reconstruction for oral obstruction secondary to giant fibrous dysplasia.
Fibrous dysplasia is a disorder of bone that may be associated with endocrinopathies and skin pigmentation. The pathologic, proliferative expansion and distortion of the skeleton is of unknown etiology. Craniofacial involvement that includes the mandible can exhibit gigantic disproportions and dysfunction. Treatment has evolved to include more aggressive strategies of resection and sophisticated reconstructive techniques. The reported case is noteworthy for the unrelenting growth of craniofacial fibrous dysplasia in an adult female with endocrinopathies, progressing to oral obstruction that required urgent treatment utilizing immediate free bone-flap reconstruction. The free fibula flap was employed to restore mandibular continuity after palliative subtotal mandibulectomy. Bony healing to dysplastic tissue occurred in the remaining mandibular segment. This case illustrates that fibrous dysplasia has the capacity for virulent regrowth subsequent to conservative resection. Defects following radical surgery for giant fibrous dysplasia of the mandible can be reconstructed with a microsurgical bone-flap technique.
