We have clinico-stastically studied 233 cases of maxillo-facial fracture patients who had been treated during the past eight years from January, 1978 to December, 1985. From this study, we obtained the following results: Of all the patients, 185 were male and 48 were female. The male/female ratio was 4: 1. Most of the males were distributed among the ages of 10 to 19 years old (28.3%) and their twenties (26.1%). The number of patients in our department show a tendency to increase every year. The causes of fractures were mostly traffic accidents (44.1%). One hundred eighty-five cases (79.5%) were referred from public or private hospitals, and only 37 cases (15.9%) from dental clinics. Fractures of the mandible alone accounted for 69. 1%. The sites of the mandible fractures were found at the condyle (25.3%), the angle of the mandible (21.9%), and other areas (52.5%). Disturbance of mouth opening were found in 67. 8% of all cases as complications of the fracture, followed by tooth injuries (62.3%), injury of the oral mucosa (36.1%), deformity of occlusion (31.3%) and unconsciousness (24.9%).
