A STATISTICAL STUDY ON FACIAL BONE FRACTURES OF KOREANS

For the establishment of the basis of treatment and study in the patients of facial bone fracture, we performed a clinico-statistical study about 28 papers and 9564 cases reported as facial bone fractures in the Journal of Korean association of oral and maxillofacial surgeons, the Journal of the Korean academy of maxillofacial plastic and reconstructive surgery, and related Journals. The results were as follows: 1. The ratio of men to wemen was 4.50:1. 2. The age frequency was highest in the third decade(37.6%), and fourth(21 5%), second(l5.5%), fifth(10 3%) decade in orders. 3. The most common location of facial bone fractures was the mandible(62.7%), and zygoma complex(22.6%), nasal bone(15.0%), and maxilla(13.0%) were next in order of frequency. 4. The major etiologic factors were traffic accident(37 9%), fisticuffs(26.4%), and falldown and slip down(23.4%). 5. The frequent fracture site of mandible is symphysis(39.3%), angle(24.4 %), and condyle(22.5%), The ratio of left to right was 1.31:1. Open reduction(69.1%) was the more frequently using method of treatment in mandibular fracture than colsed reduction(28.6%). 6. The sites of zygomatic fractures were zygoma complex(48.0%), zygomatic arch(35.7%), and combined(16 3%). The lett to right ratio was 1.37:1 7. The most frequent maxillary fracture was Le Fort I (31.4%), and Le Fort II (27.1%), unilateral(14.3%), Le Fort III (7.6%) were next in order of frequency.
