Concomitant treatment of mandibular ameloblastoma and bilateral temporomandibular joint osteoarthritis with bone graft and total joint prostheses.

Temporomandibular joint (TMJ) osteoarthritis is a degenerative disease that can create clinical problems in the masticatory musculature, jaws, occlusion, and other associated structures and is commonly accompanied by inflammatory changes and pain. Many cases of TMJ dysfunction can be managed with nonsurgical therapies, but patients with irreversible TMJ damage may require surgical intervention for repair or reconstruction. Despite various methods of TMJ reconstruction, the patient-fitted total joint prostheses may be the best option to achieve good outcomes. Multicystic ameloblastoma is a benign odontogenic neoplasm of the jaws that is found most often in the mandible, in the region of the molars, and the ramus. Ameloblastomas usually progress slowly, but are locally invasive and may cause significant morbidity and sometimes death. This report describes a case of concomitant treatment of recurrent mandibular ameloblastoma and severe bilateral TMJ osteoarthritis treated by resection of the tumor, reconstruction with bone grafting, and bilateral TMJ reconstruction in a 63-year-old woman.
