摘要 对下颌髁突骨折进行了讨论，旨在就骨折线、髁突相对于下颌骨本身的不同位置的考虑以及对可用治疗方法的评估提出一些意见，这些治疗方法将产生最完全稳定的功能性关节。为此目的，我们对180例病例进行了一系列检查，主要发现是：- 1.大多数下颌骨髁突骨折累及颈部，并从乙状切迹向下和向后延伸——低髁突骨折。 2.高位髁骨折通常与髁骨头骨折脱位有关，或见于儿童。 3. 5 岁以下儿童在髁突骨折后似乎更容易出现永久性生长变化。发现对髁突生长中心的这种损害与5岁以上患者的年龄成正比减少。 4. 在诊断时，应始终考虑髁突的位置与下颌骨其余部分的关系。 5. 早期重建正常咬合应该是制定治疗计划的首要目标。 6. 无论采用何种治疗方式，通常都会建立纤维型或骨型的愈合。因此，在保证良好的咬合和足够的下颌运动范围的情况下，固定时间不宜过长。 7. 下颌骨髁突骨折引起的并发症因其不存在而引人注目。
Summary Fracture of the mandibular condylar process has been discussed with a view to formulating some opinion with regard to lines of fracture, consideration of the various positions taken up by the condyle in relationship to the mandible proper, and evaluation of the methods of treatment available which will give rise to the most completely stable, functional joint thereafter. A series of 180 cases has been examined for this purpose, and the main findings are:- 1. Most fractures of the mandibular condyle involve the neck and run downwards and backwards from the sigmoid notch—low condylar fractures. 2. High condylar fractures are usually associated with a fracture-dislocation of the head of the condyle, or are found in children. 3. Children below the age of 5 years would appear to be more prone to permanent growth changes following fracture of the condylar process. Such damage to the condylar growth centre is found to diminish in direct ratio to the age of the patient over the age of 5 years. 4. In diagnosis the position of the condylar process should always be considered in relationship to the remainder of the mandible. 5. Early re-establishment of normal occlusion should be the primary aim in planning treatment. 6. Regardless of the mode of treatment adopted, union of the fibrous or osseous type is generally established. The period of fixation, therefore, should not be unduly prolonged, provided a sound occlusion and an adequate range of mandibular movement are ensured. 7. Complications arising from fractures of the mandibular condyle are conspicuous by their absence.
