Long-term results after childhood condylar fractures. A computer-tomographic study.

A computer-tomographic study of the remodelling process of the TMJ was made of 12 patients who had suffered condylar fractures during their growth period. The most interesting results were exhibited by patients with low fractures of the condyle and medial luxation of the small fragment. The remodelled condyles consisted of 2 parts, a medial part, probably the remainder of the small fragment and a lateral part, probably callus formation. In some patients a flattening of the fossa characterized by thickening of the roof was clearly observed. The case presentation additionally included one patient with post-traumatic ankylosis and one patient presenting a bifid condyle.
