A CLINICAL STUDY ON FACIAL BONE FRACTURES OF KOREANS

This is a retrospective study on facial bone fractures of Koreans. The study was based on a series of 817 patients with facial bone fractures treated as inpatient at Severance Hospital of Medical and Dental College of Yonsei University during the period of Jan., 1971 through Dec., 1981. The results obtained are as follows: 1. Traffic accident was the most frequent cause of facial bone fractures (46.8%). 2. The ratio of Men to Women was 3.8: 1, and admissions for facial bone fractures have been increased year after year. 3. The age frequency was the highest in second decade (37.6%) and age distribution of patients ranged from 1½years to 83 years. 4. The most common location of facial bone fractures was Mandible (37.6%), and Zygoma complex (23.5%), Nasal bone (19.9%), Maxilla (9.3%) and Others (8.4%)were next in order of frequency. One location was fractured in 75% and multiple locations were involved in 35%. Among the 735 patients except for Others (82), one-location involvements were 610(83.0%), two locations were 96(13.1%), three-locations were 23(3.1%), and entire-locations were 6(0.8%). 5. In 380 patients of Mandible fractures, 310(83.8%) had fractures only in Mandible and 70(16.2%) had another facial bone fractures. The most frequent fx. site of Mandible was Symphyseal area (38.6/) and Simple fracture was the most frequent in type of fracture (63.4%). Teeth or alveolar bone trauma cases were 31% and Open-reduction with IMF was major method of treatment (51.4%) in Mandible fractures. 6. In 91 patients of Maxillary fractures, 21 (20%) had fractures only in Maxilla and 70(78%) had another facial bone fractures. Le Fort II and Unilateral fractures (22%) were two Major type of Maxillary fx., and Le Fort I II & III were 4 cases (4.4%). Teeth or alveolar bone trauma occured in 37.4% and Open-reduction was major method of tretment (37.8%) in Maxillary fractures. 7. In 230 patients of Zygoma complx fractures, 139(60.4%) had fractures only in Zygoma complex and 91(39.6%) had another facial bone fractures. Among these, Zygoma fx. were 105(45.7%), Zygomatic arch fx. were 94(40.9%) and Zygoma & Zygomatic arch fx. were 31(13.4%), and Left Zygoma was the most frequent site. Teeth or alveolar bone trauma occured in 15.2%, and Observation (32.4%) and Open-reduction (24.5%) were major methods of treatment in Zygoma complex fx. 8. In 194 patients of Nasal bone fractures, 141(72.7%) had fractures only in Nasal bone and 53(27.3%) had fractures on another facial bones. Closd-reduction (51.1%) and Observation (31.1%) were major methods of treatment. 9. In 817 patients of facial bone fractures, 21 patients(2.5%) were expired in Hospital and 12 of these were expired in 48 hours (1.5% ). Head (48.1%), Eye (12.2%) and Lower extremeties (12.1%) were injured commonly with facial bone fractures.
