Three different techniques for mandibular reconstruction after hemimandibulectomy.
Mandibular reconstruction is a condition in which both bone defect and function must be restored. A wide range of approaches--from grafts to distant bone flaps--have been used for correcting bony defects. However, adequate mastication has been restored in only a few cases. In this article the results of three different techniques for mandibular reconstruction after hemimandibulectomy were studied. Sixteen patients underwent a second mandibular reconstruction after hemimandibulectomy and were monitored at least 1 year. Three different techniques were used: (1) full-thickness galeoparietal bone flap (eight patients), (2) free iliac crest graft (three patients), and (3) free fibular grafts (five patients). Occlusion on the nonoperated side and the possibility and function of osseointegrated denture in the vascularized bone transfer were evaluated. The full-thickness galeoparietal flap and free iliac crest bone flap appeared to be good options. However, only acceptable or poor occlusion could be achieved on the normal side. The fibular free flap demonstrated good results and good occlusion. Nonetheless, dental implantation was difficult because a prosthesis for reaching the normal height of the mandible was necessary.
