OBJECTIVE: The indications for temporomandibular joint (TMJ) reconstruction are well established, but the method of reconstruction is controversial. The purpose of this retrospective study was to compare individual prefabricated condyle implants and costochondral grafts in condyle reconstruction after tumor resection. STUDY DESIGN: We conducted a retrospective review of a case series with 28 patients treated with costochondral grafting and 23 patients treated with individual prefabricated titanium implants. For each patient, variables included both subjective (pain and interference with eating) and objective (interincisal distance) data. RESULTS: Baseline patient characteristics were similar in the 2 groups; all patients were followed for a minimum of 2 years. Patients in both groups showed an improvement in symptoms. Those treated with individual prefabricated implants had greater improvement and fewer complications than those in the costochondral group; also, more patients in the autogenous group required reoperation. CONCLUSION: Individual prefabricated condyle implants are effective in reconstruction of TMJ tumor defects. These prostheses are a viable choice in the setting of tumor resection and reconstruction, with improvement of jaw function, reduction of joint pain, and esthetic improvement.
