Long-term results of nonsurgical management of condylar fractures in children.

Twenty-five patients with 28 condylar or subcondylar fractures, sustained during their growth period and treated nonsurgically, have been followed for an average period of 15 years. The fractures were classified as intracapsular, high condylar neck and low condylar neck fractures. In 5 patients, two weeks of intermaxillary fixation, followed by elastic traction in order to achieve a proper occlusion, was applied. All the other patients were treated by instruction, exercises and observation. In 4 patients, subsequent orthodontic treatment was provided. It is not advocated to perform orthodontic aftercare as a routine action in all patients. Satisfaction with the treatment results, as measured on a visual analogue scale (VAS), was very high. The masticatory function of all patients at last follow-up was good to excellent. From this study, it appears that especially the commonly occurring high condylar fractures (64%) show good regeneration tendency as observed on radiographs. Low condylar and intracapsular fractures may give rise to some asymmetry. In 4 cases this asymmetry was clearly visible to the experienced observer, but did not concern the patient. One patient (low condylar neck fracture) showed obvious malocclusion and facial asymmetry, which needed to be corrected by orthognathic surgery. Unfortunately, it is impossible to predict which type of fracture is at risk of facial asymmetry. It is concluded that nonsurgical management of condylar fractures of the mandible in children is still the method of choice.
