THE CLINICAL STUDY ON MAXILLOFACIAL FRACTURES OF KOREAN

This is a retrospective study on maxillofacial fractures of Korean. The study was based on a series of 510 patients who had been treated for maxillofacial bone fractrues as in-patient at Yon Sei University Medical Center for the period of January, 1982 to June, 1985. The results were obtained as follows ; 1. The ratio of Male/Female was 3.9:1, and 2nd decade (34.9%) was the highest age group in incidence, and age range was 15/12 years to 76 years. 2. Traffic accident (45.1%), fighting (21.0%) were the most common causes of maxillofacial bone fractures. 3. The frequent locations of maxillo facial fractures were mandible (50.8%), zygoma and zygomatic arch (26.2%), nasal bone (8.1%) and others, in order. 4. In mandibular fractures, isolated fracture of mandible showed 86.8%, symphysis (46.7%), condyle (23.4%) and angle (19.6%), in order. 5. In fracture of maxilla, isolated maxilla, fracture was relatively low (25.7%), and zygomatic complex fracture was divided into zygomatic complex (63.8%) and zygomatic arch (31.6%). Bilateral fracture showed 4.6% and it demonstrated whether isolated or combined with other facial bones, but fracture pattern of midface was extremely variable. 6. Treatment of maxillofacial fractures was rendered open reduction in most of cases. 7. Associated injuries of maxillofacial fractures demonstrated head(49.3%), lower extremities (16%) and upper extremities (11.8%).
