Mandibular condyle fractures develop frequently and show the variable type of injury and complication. New opinions have emerged from recent investigation into condylar fractures. The author investigated 246 patients with condylar fractures who visited SNUDH from January 1980 to August, 1988, 8. with regard to clinical and treatment aspects, area and displacement of fractures, associated teeth injury and other body injury, complications. At last I have got the following results. 1. The incidence to condylar fractures in a series of 765 mandibular fractures may be as high as 32.2%. 2. The male patients are 3 times more than female patients. The highest frequency was recorded in the group 21-30 years of age. (34.1%). 3. Falls caused the greatest number of condylar fractures (45.2%) and next was in assult (25.6%), traffic accidents (22.4%). 4. Unilateral condylar fractures were present in 74.8%, giving a left: right ratio of 1.2:1. In cases of unilateral fracture, subcondylar fractures were by far the commonest (32.9%) but in cases of bilateral fracture, condylar neck fractures were by far the commonest. In children under 15 years of age, condylar neck fractures were more common but in patients over 16 years of age, subcondylar fractures were common. 5. Anteromedial fracture dislocations were by far the commonest (20.3%). In children under 15 years of age, fracture deviations were common but in patients over 16 years of age, fracture displacements were common. 6. 44.7% of patients with condylar fractures sustained the teeth injuries. Teeth fractures were by far the commonest. 7. Single condylar fractures showed a frequency of 30.5%. Of the concomitant fractures elsewhere in the mandible, symphysis fractures were by far the commonest (54.1%). 8. Associated other body injuries showed a frequency of 28.0%. Of them, head injuries were by far the commonest. 9. The mean interval from injury to treatment was 14.3 days. Of the treatment of condylar fractures, open reduction was by far the commonest (70.3%). Closed reduction comprised 19.9% and functional therapy comprised 8.5%. 10. In 67 patients with possible follow up period, the following complications were developed, two ankylosis, anterior open bite, mouth opening limitation, mouth opening deviation.
下颌髁突骨折较为常见，损伤类型和并发症多样。近年来对髁突骨折的研究出现了一些新观点。作者对1980年1月至1988年8月期间到首尔国立大学牙科学院就诊的246例髁突骨折患者进行了调查，内容涉及临床和治疗方面、骨折部位和移位情况、相关牙齿损伤及其他身体损伤、并发症等。最后得出以下结果：1. 在765例下颌骨骨折中，髁突骨折的发生率高达32.2%。2. 男性患者是女性患者的3倍。发病频率最高的年龄段为21 - 30岁（34.1%）。3. 跌倒导致的髁突骨折数量最多（45.2%），其次是袭击伤（25.6%）、交通事故伤（22.4%）。4. 单侧髁突骨折占74.8%，左右比例为1.2:1。在单侧骨折病例中，髁突下骨折最为常见（32.9%），但在双侧骨折病例中，髁突颈部骨折最为常见。15岁以下儿童中，髁突颈部骨折更为常见，而16岁以上患者中，髁突下骨折较为常见。5. 前内侧骨折脱位最为常见（20.3%）。15岁以下儿童中，骨折偏斜较为常见，而16岁以上患者中，骨折移位较为常见。6. 44.7%的髁突骨折患者伴有牙齿损伤。牙齿骨折最为常见。7. 单髁突骨折的发生率为30.5%。在下颌骨其他部位的合并骨折中，正中联合骨折最为常见（54.1%）。8. 合并其他身体损伤的发生率为28.0%。其中，头部损伤最为常见。9. 受伤至治疗的平均间隔时间为14.3天。在髁突骨折的治疗方法中，切开复位最为常见（70.3%）。闭合复位占19.9%，功能治疗占8.5%。10. 在67例可能进行随访的患者中，出现了以下并发症：2例关节强直、前牙开、张口受限、张口偏斜。
