RESUMO
Background: Multitudes of options are available for reconstruction of functional and cosmetic defects of the mandible, caused by various ailments. At the present time, autogenous bone grafting is the gold standard by which all other techniques of reconstruction of the mandible can be judged. The purpose of this study was to evaluate the outcome of different osseous reconstruction options using autogenous bone grafts for mandibular reconstruction. Methods: This Interventional study was conducted at Department of Oral and Maxillofacial Surgery, King Edward Medical University/Mayo Hospital Lahore, from January 2008 to July 2009 including one year follow-up. The study was carried out on thirty patients having bony mandibular defects. They were reconstructed with the autogenous bone grafts from different graft donor sites. On post-operative visits they were evaluated for outcome variables. Results: Success rate of autogenous bone grafts in this study was 90%. Only 10% of the cases showed poor results regarding infection, resorption and graft failure. Conclusion: Autogenous bone grafts, non-vascularised or vascularised, are a reliable treatment modality for the reconstruction of the bony mandibular defects with predictable functional and aesthetic outcome
RESUMO
To determine the results of using the free vascularized fibular flap for comprehensive reconstruction of post-resection or post-traumatic mandibular defects. Department of Oral and Maxillofacial Surgery, King Edward Medical University, Lahore, from March 2007 to June 2009. The study group consisted of patients who underwent reconstruction of continuity defects of the mandible using a fibular vascularized free flap. Indication for mandibular resection were squamous cell carcinoma of the floor of the mouth and alveolar ridge in 5 cases, ameloblastome of the mandible in 6 cases, odontogenic keratocyst in 3 cases, defect due to fire arm injury in 2 cases and central giant cell granuloma of the mandible in one case. The type of reconstruction performed was primary reconstruction in 11 patients and secondary in 6 patients. There were 17 patients including 14 males and 3 females with mean age of 40 years. All flaps except three survived. One patient died due to complications related to blood transfusion. Of those, 2 completely failed, one due to the unfavourable recipient bed of the patient with fire arm injury and other due to venous thrombosis. Donor site morbidity was low; there was some compromise in the ankle function but none of the patient complaint of foot drop. Simple problems with wound healing such as dehiscence and delayed wound healing developed in 5 patients, which usually required only local antiseptic treatment. After the operation patient began oral feeding and walking with some aid in fourth week and became completely ambulant in 8 weeks. In this small series the free fibula flap was a versatile and reliable option for microvascular reconstruction of large mandibular defects. It provided a large quantity of bone, which could be easily shaped and passively adapt to the remaining mandible and for an implant-based prosthetic restoration
