Early experience with biodegradable fixation for congenital pediatric craniofacial surgery

We describe early experience using a polymeric bioresorbable bone fixation system in a consecutive series of eight pediatric patients for the correction of craniofacial malformations. Indications for surgical treatment included craniosynostosis (7) and encephalocele (1). All patients underwent bifrontal craniotomies with cranial vault or orbital reconstruction or both. Segments were then stabilized using bioresorbable fixation systems. Patients were evaluated pre- and postoperatively clinically and with radiographs and photographs. Mean follow-up was 4.5 months, with a minimum follow-up of 3 months. In seven of eight patients, there was no incidence of infection, extrusion, exposure, erythema, instability of the advanced segments, relapse, hematoma, seroma formation, or adverse inflammatory reaction. One patient experienced difficulty with respect to system imperfections (i.e., drill holes after tapping were too large for screws). This study demonstrated the efficacy of bioresorbable plates and screws for the growing pediatric craniofacial patient; excellent short-term results were achieved. Prospective studies and longer longitudinal follow-up of larger numbers of patients are desirable to confirm these findings.
