Surgical Outcomes of Craniofacial Fibrous Dysplasia in the Pediatric Patient

Surgical treatment and outcomes of fibrous dysplasia (FD) in pediatric patients are areas that have not been fully studied. The authors completed a retrospective review of 20 patients who had at least one surgery for craniofacial fibrous dysplasia before 18 years of age. Surgeries were categorized into 3 groups: bone contouring only; removal of the involved bone, contouring, and replacement of the contoured bone; or en bloc resection of the involved bone and reconstruction with an alloplastic material, bone allograft, or bone autograft obtained from non-involved sites. A total of 36 distinct surgical procedures were performed in 20 patients, with a mean number of 1.9 surgeries/patient (range 1–5). The maxilla was both the bone that was most commonly affected and most commonly operated on. The most common surgical indication was visible or palpable growth in 63.9% of cases. Bone contouring only was the initial surgery in 15 patients, of whom 9 patients (55.6%) had continued bone growth requiring subsequent surgeries. Removal, contouring, and replacement wasthe initial surgery in 1 patient, who required a secondary surgery. Four patients, all with monostotic calvarial disease, initially had an en bloc resection and reconstruction; none had recurrence. Patients with subsequent surgeries had a mean time to operation of 3.7 years (range 0.24–9.8). The recurrence rate and need for secondary surgical procedures were relatively high in patients who had bone contouring only. These patients tended to be patients with facial bone involvement more than calvarial involvement.
