2.固定方法选择: (1)骨间结扎—此法对新鲜骨折,陈旧性骨折,以及有牙和无牙的颌骨骨折均适用,是一种可靠的固定方法。可采用口内或口外进路,用手术方法暴露骨折断端,在骨折段处钻孔,穿过不锈钢丝,将骨折段正确复位后进行结扎固定。口外法骨折段钻孔的位置,应在下颌体近下颌缘处,以免损伤牙龈、牙胚和下牙槽神经和血管。应距骨折线为0.5～1.0cm。钻孔数目应视骨折线部位,斜面,肌肉牵拉力大小而定。一般各钻1～2孔即可,以能达到骨折段结扎牢固为准。
2. Selection of fixation methods: (1) Interosseous ligation - this method is a reliable method of fixation for fresh fractures, old fractures, and jaw and toothless fracture of the jaw. Can be used intraoral or extraoral approach, surgical methods exposed fracture ends, holes in the fracture section, through the stainless steel wire, the fracture section after the correct reset ligation and fixation. Bone fracture extraoral drilling position, should be in the lower jaw near the mandible edge, so as not to damage the gums, tooth germs and the lower alveolar nerve and blood vessels. The fracture line should be 0.5 ~ 1.0cm. The number of holes should be considered fracture site, bevel, muscle pull size may be. General drilling 1 or 2 holes can be, to be able to achieve a solid ligation of the fracture segment shall prevail.
