在颌面部损伤的临床上,应用金属丝缝合作下颌骨折片的固定是最常用的方法。此法有一些优点,但也有一些缺点,如破坏骨折区域的血液循环,有较大的压力,可发生流电流等。为了改进下颌骨接骨术的方法,作者提出应用具有惰性的聚乙烯作标准塑胶夹板。材料和方法:标准塑胶夹板如图所示,固定头呈蘑菇状。各突起间的距离为1cm。按骨折线的特点(直的或斜的),选用内侧有蘑菇头的,或内侧和外侧都带有蘑菇头的。夹板的长度为2.5cm,重量为0.5g。在局麻下,从下颌骨的外侧面暴露骨折线,内侧骨膜不剥离。除夫骨折线卜的嵌塞物。按
In the clinical treatment of maxillofacial injuries, the use of wire suture fixation of mandibular fracture is the most commonly used method. This method has some advantages, but there are also some disadvantages, such as destroying the blood circulation in the fracture area, there is greater pressure, flow current can occur and so on. To improve the method of mandibular osteosynthesis, the authors propose the use of an inert polyethylene as a standard plastic splint. Materials and methods: Standard plastic splint as shown, the fixed head was mushroom-shaped. The distance between the protrusions is 1 cm. According to the characteristics of the fracture line (straight or oblique), the selection of mushroom head inside, or inside and outside with mushroom head. The length of the splint is 2.5 cm and the weight is 0.5 g. Under local anesthesia, the fracture line is exposed from the lateral surface of the mandible and the periosteum does not peel off. In addition to the fracture line Bu implosion. press
