下颌骨占面下 1/ 3区域 ,极易受到意外打击致伤。发生在下颌骨的骨折约占颅面骨折病例的2 / 3。而且多有骨折断端移位和咬牙合关系紊乱[1] 。颌间牵引等保守疗法常影响患者说话和营养摄入且骨断端对位欠佳 ,疗效不能保证 ,骨间钢丝结扎固定对多线、不稳定性骨折效果较差。微型 The mandible occupies 1/3 of the area under the surface, vulnerable to accidental blow injuries. Fractures that occur in the mandible account for about two-thirds of craniofacial fractures. And more fracture fracture displacement and occlusal occlusal relationship [1]. Interventional traction and other conservative treatment of patients often affect speech and nutritional intake and poor bone alignment, curative effect can not be guaranteed, interosseous wire ligation fixed multi-line, unstable fracture less effective. miniature
