Postoperative complications of delayed osteosynthesis with stainless steel miniplates were examined in 110 patients with mandibular fractures. The miniplates were removed in 91 of the patients, even if symptom-free, once sufficient bony union was obtained, and the healing conditions and the surrounding tissues were examined. Malocclusion, exposure of miniplates, delayed union, and infection were observed in 3.6%, 3.6%, 1.8%, and 1.0% of the patients, respectively. The complication rates were within acceptable limits even when treatment was performed later than 24 hours after injury. The healing conditions and the surrounding tissues did not show any serious problems. Thus, at least in short-term retention, stainless steel miniplates seem to be effective and suitable for osteosynthesis of mandibular fractures.
