Abstract

Recently the goal of orthognathic surgery has been focused on esthetic improvement of the patients. Also early corrective surgery was favorable selected by most of the oral maxillofacial surgeons. We should consider the etiologic factor of the patient's dentofacial deformities when treatment is planned, because this is major factor in estimating the predictability or stability of result. The more researches were carried on the etiologic factors of the dentofacial deformities. The more possibility of the early surgical correction will be increased. The authors analyzed about etiologic factors and epidemiologic studies of the forty patients who had received the orthopaedic surgery. The analysed results were as follows : 1. The predilection ration between male and female was 17:23, and 32 patients(80%) of 40 patients were aged twenties 2. 26patients(65%) complained estetic problems as well as functional problems. 10 patients(25%) complained only esthetic problems, and 4 of 40patients complained only functional problems. 3. Mandibular prognathism was found to be done most frequently(25.39%). Facial asymmetry(13.20%) and angle hypertrophy were found to be next in sequence. 4. Sagittal split ramus osteotomy was done most frequently(27.35%). Lefort I osteotomy(13.17%), angle reduction(12.16%), and genioplasty(11.15%) were done also. 5. The number of the cases due to nonspecific etiologic factor was 22(55%). that of cases due to inhertied tendency was 12(30%), that of cases due to congenital anomaly was 3(7.5%), and that of cases due to trauma was 3(7.5%) 6. The number of patients who got only maxillary surgery was 2(5%), that of patients who got only mandibular surgery was 23(57.5%), and that of patients who got simultaneous two jaw surgery was 15(37.5%).
