Adaptation of autogenous costochondral grafts used for temporomandibular joint reconstruction: a long-term clinical and radiologic follow-up.

The clinical and radiologic behavior of autogenous costochondral grafts used for temporomandibular joint (TMJ) reconstruction was studied in 16 patients with a mean follow-up of 10 years. The grafts were classified into four groups according to the degree of radiologic calcification or remodeling (adaptation). Total adaptation was observed in six cases and in two cases, no changes were found. The function of the new joint was excellent irrespective of the radiologic status and seemed to improve with time.
