[Results of the use of titanium mandibular reconstruction plates]

The aim of this study was to assess the use of titanium mandibular reconstruction plates after cancer surgery. The medical records of 36 patients were reviewed. The mean follow-up was 22 months. All patients had primary reconstruction of the mandible with Leibinger titanium plates. Thirty patients underwent postoperative radiotherapy with the plate in the field. The mean dose was 60 Grays over 6 weeks and the overdosage into tissues was reduced to 5%. Thirty patients (83%) had retained the plate at 6 months and no sign of osteomyelitis was found in any patient. Quality of speech and deglutition were satisfactory in 63% and 94% of the patients respectively; sixty-six p. cent of them found their cosmetic appearance good or excellent. The overall success rate of the technique was 74%. This technique did not excessively prolong operating time unlike microvascular transfer. Plates are an effective method of primary reconstruction in patients with advanced cancer and uncertain long-term survival. Tolerance of plates after radiotherapy is outstanding. Speech, deglutition and facial contour are immediately restored and further bone reconstruction is feasible.
