Mandibular Ramus/Coronoid Process Grafts in Maxillofacial Reconstructive Surgery

Purpose: To evaluate the utility of autogenous extended mandibular ramus and coronoid process bone grafts for maxillofacial reconstructive surgery. Patients and Methods: Twelve patients aged 23 to 76 years (mean, 52) who underwent extended ramus/coronoid process grafts for reconstruction of maxillofacial deformities due to trauma, alveolar atrophy, or iatrogenic nasal deformity. All patients had either unilateral or bilateral combined coronoid process-mandibular ramus bone grafts for their reconstruction. There was 1 nasal reconstruction, 2 unilateral mandibles, 1 bilateral mandible, 4 unilateral maxillas, 1 unilateral maxilla and mandible combined, and 1 bilateral maxilla and mandible combined. Results: The procedure was considered a success when the patient's deformities were reconstructed ad integrum and when there were no failures of the dental implants placed in the augmented areas as of the longest follow-up. All patients were successfully reconstructed. There was 1 infection at a donor site that resolved with local care and oral antibiotics. All but 1 of the maxillary and mandibular alveolar augmentations underwent endosteal implant placement approximately 4 to 6 months following grafting. The nasal reconstruction restored normal function and symmetry. Conclusion: Using both the coronoid process of the mandible and the mandibular ramus as a source for autogenous bone graft can provide sufficient bone in quantity and quality for selected maxillofacial reconstructions.
