摘　　要：目的：分析下颌骨骨折骨不连的临床特点和治疗。方法：对1087例下颌骨骨折中24例骨不连病例的部位、病因、治疗及结局进行回顾性分析。结果：下颌骨骨折骨不连发生率为2．2％；以颏部、下颌体多发。固定不良所致骨不连11例，均通过坚强内固定治疗；骨缺损所致骨不连10例，同期植骨9例；骨感染所致骨不连3例，死骨刮治同期植骨2例。23例骨不连术后3～6月骨愈合。结论：下颌骨骨折骨不连发生率较国外报告低。固定不良、骨缺损、骨感染是下颌骨骨折骨不连主要病因。骨不连的治疗主要根据病因进行增强固定、骨断端刮治、骨缺损植骨。Objective ：To evaluate the characteristics and the treatment of nonunion cases of mandibular fractures. Methods ：24 patients with 28 sites of nonunion of mandibular fracture were retrospectively investigated. The involvement came from the group of 1087 cases who were treated from 1990 to 2004 in Department of Oral and Maxillofacial, Peking University School of Stomatology. The data were recorded and analyzed. Results： The nonunion rate was 2.2% in present study. Furthermore, mental region and mandibular body were the most common sites of nonunion fracture. 11 patients caused by inadequate fixture were treated only by improving fixation and 9 out of 10 patients in whose nonunion was caused by fracture bone defect were treated by bone grafting. On the other hand, 2 out of 3 patients of nonunion caused by bone infection were treated by curetting the inflammation lesion and bone grafting. 23 patients all healed after 3 - 6 months postoperatively except 1 patient. Conclusion ： The incidence of nonunion is lower than those reported by other researchers outside China. Inadequate fixture, fracture bone defect and bone infection are three causes contributing to nonunion of mandibular fractures. The treatment for nonunion includes improving fixture, curetting the inflammation lesion and bone grafting.
