Autogenous Corticocancellous Iliac Bone Graft in Reconstruction of Mandibular Defect: Point of Technique

Abstract

Mandible resection and subsequent defect created lead to aesthetic and functional abnormalities. The surgical 
reconstruction of the defect is a major challenge in maxillofacial surgery. Lack of appropriate facilities and the high cost of 
newer modalities made the use of non-vascularized iliac bone graft in reconstruction of mandibular defect an attractive option 
in our environment. The technique of harvesting iliac crest graft is highlighted in this prospective study involving 37 iliac crest 
grafts for mandibular defect reconstruction between 1999 and 2006. Ameloblastoma was the most common indication for 
mandibular resection in 27 patients (73 percent), while 24 patients (64.9 percent) had hemimandibulectomy which is the most 
common type of mandibulectomy. A graft take rate of 91.1percent was achieved in this study. Graft site infection was the most 
complication with overall incidence of 27.0 percent. Most of the infections were superficial and responded to antibiotic use and 
local wound care. Donor site complications were few in the study. We recommend the use of autogenous iliac bone graft for 
reconstruction of mandibular bone defect in our environment.
