Abstract Objective: The purpose of this study was to determine the success rate of costochondral bone grafts used to replace absent or nonfunctioning temporomandibular joints and the subsequent growth of these grafts when placed in young children. Design: This is a retrospective study of all cases with adequate follow-up records that were treated at the Craniofacial Centre at Toronto's The Hospital for Sick Children from 1974–1986. A total of 55 patients were evaluated, of whom 13 were growing children. Results: The findings suggest that there was increased success when surgery was performed at an early age. Poorer results were achieved when previous surgery had been performed or when pathology was present. Growth of the graft did not always equal the growth of the “normal” side, but in most cases a satisfactory symmetry was achieved. Several cases exhibited excessive overgrowth. Conclusions: Surgery at 4 to 5 years of age will alleviate the impact of a severe facial deformity on the child during the earl...
