We report a case of recurrent ankylosis of the temporomandibular joint in a 9-year-old boy. He fell on his face one year prior to admission and developed swelling and pain at the region of the left cheek. Subsequently, he experienced increasing difficulty in opening the mouth, resulting in complete inability to open the mouth. The patient underwent an operation on the temporomandiblar joint at a certain college hospital. After the operation he could open his mouth for a distance of 18mm. But he was unable to open his mouth again since the age of 6 years, so visited our department. He developed an asymmetry of the face with deviation of the chin to the left and his chin was receded. He could open his mouth for a distance of only 1.5mm. Roentgenograms revealed bony ankylosis of the left temporomandibular joint. We performed an osteoarthrotomy on left side. At 2 years and 6 months after this operation he was able to open his mouth for a distance of 29mm.
