Experience with AO reconstruction plates after partial mandibular resection involving its continuity.

A report is presented on experience with the use of 54 plates, without primary bone grafts, after resections for malignant tumours involving the continuity of the mandible, in 52 patients. There were complications in 27 cases: postoperative infection or soft tissue dehiscence occurred 20 times, chronic soft tissue perforation once, screw loosening twice, and plate fracture four times. Adjuvant radiotherapy and/or chemotherapy had no effect on the incidence of the complications. Seventeen of the plates (a good 30%) had to be removed prematurely due to the complications. Major deformity did not always occur if relative stabilization had developed through cicatrix formation. Thirty-seven plates (barely 70%) remained: in 19 cases until the death of the patient, in 3 cases until recurrence, in 12 cases until bone grafting, and in 3 cases they were still in situ up to 65 months. In principle, reconstruction plates have proven themselves. However, application and soft tissue coverage need great care and a great deal of experience.
