Abstract

Clinical retrospective investigation was conducted on mandibular condylar fractures of 100 hospitalized cases at the Department of Oral Surgery, Kyoto University Hospital during the period from 1973 to 1983. The following results were obtained, 1. There were 74 males and 26 females. The age of the patients at the time of injury ranged from 4 to 78 years old. The average age was 28.1 years old. 2. Twenty-six patients were treated within a week of injury, 22 cases within 2-weeks and 33 cases were treated after more tham 3 weeks. 3. Of the 100 cases, 70 were unilateral fractures and 30 were bilateral. The incidence of the concomitant fractures of the mandible were higher in bilateral than in unilateral condylar fractures. 4. On fracture level and form 130-site in 100 patients were divided according to the classification of Maclennan and Kubo. Dislocated and high condylar fractures were most frequently observed. 5. Surgical reduction was mainly achieved in low neck fracture, and the contrary conservative treatment was observed in the higher level fracture. On the other hand condylectomy was infrequently indicated in the dislocated head fracture.

下颌髁突骨折的临床研究。1. 回顾性分析100例130例颞下颌关节骨折,并对不同部位和不同形式的骨折进行特殊治疗。
对1973 ~ 1983年在京都大学医院口腔外科住院治疗的100例下颌髁骨折患者进行临床回顾性调查。得到了以下结果:1。男性74人,女性26人。患者受伤时的年龄从4岁到78岁不等。平均年龄28.1岁。2. 伤后1周内治疗26例,2周内治疗22例,3周以上治疗33例。3.100例中,70例为单侧骨折,30例为双侧骨折。双侧髁突骨折的发生率高于单侧髁突骨折。4. 按Maclennan和Kubo分类对100例患者的130个部位进行骨折程度和形式的分型。脱位和高位髁骨折是最常见的。5. 手术复位主要在低颈骨折中实现,而在较高水平骨折中观察到相反的保守治疗。另一方面,在脱位的头部骨折中很少有髁突切除术。
