[Indication for condyle reconstruction in TMJ fractures during childhood]

Four cases of unilateral juvenile growth retardation of the lower jaw caused by trauma of the temporomandibular joint are presented (age 5-13 years, 1 female, 3 male). Three cases had ankylosis of the TMJ. In all patients, a reconstruction of the condyle by transplantation of rib or iliac crest grafts was performed. Follow-up time was 1.5 to 3 years. Postoperatively, good function was achieved in all cases; a tendency for growth induction was found in 3 cases, overgrowth in one case. Severe impediment of lower jaw mobility, when combined with foreseeable growth impediment, as well as traumatically induced hypoplasia are proposed as indications for autologous joint reconstruction.
