Abstract

Vascularized free bone grafts have been used extensively for reconstruction of the mandible. When surgical resection includes the temporomandibular joint, definitive management remains controversial. We describe a novel technique that involves the use of a fibula free flap with Alloderm™ to reconstruct the lateral hemi-mandible and temporomandibular joint capsule. The study was performed by retrospective review of a case series at an academic center. Patients undergoing composite resection of the lateral hemi-mandible including the condyle with disruption of the temporomandibular joint were evaluated. These patients were all reconstructed with a vascularized fibula free flap with an Alloderm neocondyle reconstruction. There were nine patients with a mean age of 49.9 years. Mean follow-up was 13.1 months. There were no flap failures, infections, or complications. All patients reported improved facial symmetry, excellent jaw opening, and acceptable occlusion. AH patients were able to tolerate a soft oral diet following surgery. No patients required gastrostomy tubes postoperatively. The lateral hemi-mandible and temporomandibular joint can be resected and successfully reconstructed using a fibula free flap with Alloderm to create the neocondyle. Improved postoperative cosmesis, decreased trismus, adequate jaw opening, minimal jaw drift, and the ability to chew were achieved in the majority of patients treated in this manner.
