Numerous methods are available for mandibular reconstruction following composite resection. Success of mandibular reconstruction is measured not only in terms of tumor control and survival but also in final cosmetic and functional rehabilitation. Twenty-four mandibles had been reconstructed temporarily using AO plate at the Department of Oral and Maxillofacial Surgery, Kurume University School of Medicine since 1984.<BR>Among 24 patients, 15 males and 9 females, 16 were successfully treated and 8 were not, therefore, the overall success rate of mandibular plate reconstruction was 66.7 % and the mean follow-up period was 43.5 months (12 to 120 months). Ten patients (41.7 %) had postoperative complications, including 29.2 % of infection, 20.8 % of plate exposure, and 20.8 % of bone loss, hence 2 were cured conservatively and 8 plates were removed. The incidence of postoperative complication was significantly higher when the area had been irradiated preoperatively at the dose of 30 Gy or more. Reconstructed mandible with AO plate and free bone graft was unsuccessful in three cases. On the other hand, AO plate reconstruction combined with or without flap was not concerned with success rate.<BR>In conclusion, the use of an AO plate should be limited only when the mandible is not irradiated over 30 Gy and when there is a possibity of soft tissue covering the plate.
