A follow-up study of condyle fracture in children.

This paper reports a long-term clinical and radiological evaluation of conservatively treated condylar fractures in children. The long-term effects of treating condylar fractures in children with non-surgical therapy were examined in order to resolve the controversial question 'Does complete remodeling occurs at this age or, if not, is it more likely to be associated with certain types of fractures or other factors?' This study was based on a series of 11 consecutive children and adolescents, aged between 3 and 15 years, with fractures of the condylar process who had been treated with conservative therapy. All patients underwent a clinical investigation with a special emphasis on the temporomandibular joint function and facial asymmetry. The patients also underwent a radiological investigation, focusing on the fracture remodeling and symmetry of the mandible, which consisted of a panoramic radiograph, PA and a lateral cephalogram and 3-D CT. No patient complained of an impaired temporomandibular joint (TMJ) function or pain on the affected side. Two out of eight (25%) unilateral and one bilateral fracture show a slight facial asymmetry. Despite the apparent excellent recovery of function, there were marked remodeling changes evident on the CT scan. Such changes are not usually evident on a panoramic radiograph. The radiological investigation showed an incomplete remodeling (six patients, 54.5%) and an asymmetry of the mandible (three patients, 27.3%) in some patients. Non-surgical treatment of condylar fractures in children results in the satisfactory long-term outcome of the jaw function despite the relative high frequency of radiologically noted aberrations.
