Rigid fixation in reconstruction of craniofacial fractures.

Ninety-four patients had either isolated fractures of the skull or midface, or combined fractures of the skull, periorbit, and/or midface. Thirty-five of these patients were treated by conventional methods, including maxillomandibular fixation (MMF) 4 to 6 weeks postoperatively, wire osteosynthesis, suspension ligatures, or a head frame. The remaining 59 patients were treated with either mini-, low-profile, micro-, or 3-D titanium plate fixation (rigid internal fixation [RIF]) and comprise the patient population for this study. Of the 59 patients, 11 were female and 48 male, ranging in age from 6 to 85 years, with a mean age of 34 years. Six patients had isolated skull fractures, 9 had combined skull and periorbital fractures, 31 had isolated midface fractures, and 13 patients had combined skull and midface fractures. The follow-up period ranged from 3 to 48 months. Patients with midface fractures were placed in MMF intraoperatively, and MMF was released at the completion of the procedure. At 2 to 4 days postoperatively, the occlusion was evaluated. Fifteen of the 38 dentate patients with either midface or combined skull and midface fractures were without MMF postoperatively. Twenty-three patients showed slight occlusal discrepancies and were treated with elastic MMF for 3 to 28 days (mean, 10 days). All reductions were judged to be stable throughout the postoperative course. Based on the results, use of RIF is recommended for primary reconstruction in craniofacial trauma patients whenever possible, thereby achieving three-dimensional stability, sufficient functional and cosmetic results, and often avoiding or reducing the need for MMF.
