Costochondral grafts have gained increasing popularity among oral surgeons in reconstructing the mandibular condyle in cases, such as ameloblastoma. Seven patients with mandible ameloblastoma were treated with resection and immediate reconstruction by mean of autogenous non-vascularized costochondral at the Department of Oral and Maxillofacial Surgery, Stomatology Instalation, Dr. Soetomo General and Teaching Hospital. Analysis of the results was gained as a result of a retrospective study of patients when they attended appointments for 1 year post op follow up. Clinical and radiological evaluations obtained during the follow up showed significant anatomical and functional rehabilitation of the mandible as a result of the costochondral graft. The conclusion of this study is that free costochondral grafting is a successful technique for reconstruction of portions of the mandible and its temporal articulation The purpose of this study is to evaluate costochondral graft reconstruction of the mandibular condyle after hemimandibulectomy.
