Abstract　： [Abstract] A nine-year-old boy sustained a unilateral fracture of the mandibular condylar process and was treated with closed reduction. The patient wore a removable resin splint for two weeks and was put on a soft diet for ten days following the fracture without maxillomandibular fixation. We examined the morphological changes in the fractured condyle by means of conventional radiography and three-dimensional reconstruction computed tomography one year and two years after the fracture. The condylar movements were also recorded with computerized axiography to evaluate the function of the patient's temporomandibular joint. Computed tomography showed that a condylar process-like structure had been morphologically reconstructed. On the fracture side, an anterior deviation of the condyle in the glenoid fossa was observed. No dysfunction of mandibular movement during mastication was found in clinical examinations; however, horizontal condylar inclination was significantly reduced on the side of the fracture compared with that of the uninjured side. Closed treatment achieved clinically successful results for the unilateral fracture of the mandibular condylar process in this child. Furthermore, it appears that placing a patient on a soft diet in the early period without maxillomandibular fixation helps the morphological and functional adaptation of the temporomandibular joint after condylar process fractures in children.
