颌面部骨折虽然已经有了比较完善的治疗方法,但对儿童颌骨骨折,无牙颌或缺牙较多情况下的复杂粉碎骨折,在临床处理上也往往感到困难,我们自1986年10月以来应用自制牙用不锈钢丝U形骨钉行颌面部骨折固定术21例,取得了良好效果。初步报道如下。临床资料与方法应用市售直径为1.0～1.2cm牙用不锈钢丝加压制成扁方形或用市售同型号(牙合)支托钢丝弯制成U形骨钉备用。骨钉长度0.8～1.2cm,深入骨松质之钉2～4mm。切开组织暴露骨折断端外侧旨面,在适当部位用多功能气动骨钻钻孔,暂时固定上下颌骨于正常(牙合)关
Although maxillofacial fractures already have a relatively complete treatment, but in children with jaw fractures, edentulous or missing teeth more complex comminuted fracture, the clinical treatment is often difficult, we since 1986 10 Months since the use of homemade stainless steel wire with U-shaped bone nail maxillofacial fracture fixation in 21 cases, and achieved good results. Preliminary reports are as follows. Clinical data and methods The commercially available diameter of 1.0 ~ 1.2cm dental stainless steel wire pressed into a flat square or with the same type of commercially available (occlusal) support wire bend made of U-shaped bone nail backup. Bone nail length of 0.8 ~ 1.2cm, deep bone cancellous nail 2 ~ 4mm. Cut open the exposed end of the fracture surface of the lateral gingiva, in the appropriate parts of the hole with a multi-function pneumatic drilling, temporary fixation of the mandible in the normal (occlusion) off
