This is a retrospective statistical study on zygoma fractures. This study was based on 83 cases of zygoma fractures treated surgically in Dept. of Oral and Maxillofacial Surgery, Chungnam National University Hospital from May, 1985 to Sep., 1988. Among the many items the type of fractures and surgical methods were emphasized. For convenience sake, the zygoma fracture were classified according to Knight & North's classification. The results obtained are as follows: 1. The zygoma fractures occupied 31.9% of facial bone fractures. 2. The main age group were the second decade (37.5%) and the third decade (30.0%) and the ratio of mail and femail was 5.7:1. 3. The main contributing causes of fractures was traffic accident (71.3%). 4. The zygoma fractures were classified in 6 Group. Group 1. Undisplaced fractures were 8.4%. Group 2. Only arch fractures were 9.6% Group 3. Tripod with unrotated body were 32.5% Group 4. Tripod with medially rotated body were 20.5% Group 5. Tripod with laterally rotated body were 9.6% Group 6. Complex fractures were 19.2% 5. Fixation were required in 69 cases (83.1%) after adequate reduction. 6. Fixation area the most frequently used was zygomaticofrontal suture (71.1%), and infraorbital rim (43.3%), zygomatic arch (16.9%), zygomatic buttress (6%) were followed.
这是一项关于颧骨骨折的回顾性统计研究。本研究基于1985年5月至1988年9月在忠南国立大学医院口腔颌面外科接受手术治疗的83例颧骨骨折病例。在众多项目中，重点关注了骨折类型和手术方法。为方便起见，颧骨骨折按照奈特和诺思的分类法进行分类。所得结果如下：1. 颧骨骨折占面骨骨折的31.9%。2. 主要年龄组为第二个十年（37.5%）和第三个十年（30.0%），男女比例为5.7:1。3. 骨折的主要致伤原因是交通事故（71.3%）。4. 颧骨骨折分为6组。第1组：无移位骨折占8.4%。第2组：仅弓部骨折占9.6%。第3组：体部未旋转的三脚架骨折占32.5%。第4组：体部向内侧旋转的三脚架骨折占20.5%。第5组：体部向外侧旋转的三脚架骨折占9.6%。第6组：复杂骨折占19.2%。5. 69例（83.1%）在充分复位后需要固定。6. 最常使用的固定区域是颧额缝（71.1%），其次是眶下缘（43.3%）、颧弓（16.9%）、颧支柱（6%）。
