Long-term follow-up study was done on eight patients in child age with mandibular condylar fracture. A conservative treatment was done on five cases, and surgical reduction was carried out on three patients. The ages of patients at trauma were distributed from 6 to 14 years old, and the average follow up period was 7.5 years. The criteria for assesment of the posto-perative jaw function is classified into four groups: Excellent, fair, poor, and no good (Nakatomi, 1964). Four cases were evaluated “excellent”, two “fair” and two were assessed “poor”.<BR>Deviation-type fracture (MacLennan, 1952) in association with suspected pressured injury on the condylar surface seemed to have a closer relation to the poor result than the Dislocation type. Two chronic-case patients were included in the patients of Deviation type fractured group. Between the surgically-treated and conservatively cared patient groups, there is no obvious difference in the clinical course.
