本文介绍了近十年来,世界上在下颌骨因良性肿瘤切除后断裂缺损即时植骨修复方面的临床经验,以及有关植骨方面一些研究动态。多数人认为,下颌骨切除后的断裂缺损以即时植骨修复为好。在骨源方面以自家新鲜疏松骨为首选,同种异体骨为其次,异类骨正在开始试用。下颌骨造釉细胞瘤以用截除病变颌骨法效果较好,挖除法复发率为55％—100％。总结下颌骨断裂缺损时植骨成功的经验为:一、病人健康状况良好;二、适当的抗菌素控制;三、正确准备植骨床(包括清除感染等);四、在无张力下缝合伤口;五、植骨要适当固定和制动。少数人在下颌骨恶性肿瘤切除后,已开始试用自家新鲜骨即时植骨修复缺损;多数人认为在恶性肿瘤治愈无保证情况下不宜用自家骨修复缺损。在研究方面:一、改进同种异体骨的保存方法和提高其成活率。二、异类骨在下颌骨植骨的应用。
This article describes the clinical experience of the world in orthopedic resection of the mandible for immediate bone graft repair in the last decade and some recent studies on bone graft. Most people think that the fracture after mandibular resection defect with immediate bone graft repair is better. In terms of bone source to their own fresh loose bone as the first choice, followed by allogeneic bone, heterogeneous bone is beginning trial. Mandibular ameloblastoma in order to cut off the effect of the jaw better, digging method of recurrence rate of 55% -100%. Summarize the experience of successful bone grafting in the case of mandibular fracture: First, the patient's health is good; Second, the appropriate antibiotic control; Third, the correct preparation of bone graft bed (including removal of infection, etc.); Fourth, Five, bone graft should be properly fixed and brake. A small number of patients with mandibular malignancy resection, has begun trial of their own fresh bone real-time bone graft repair defects; most people think in the case of malignant tumor without guarantee should not use their own bone repair defects. In research: First, to improve the preservation of allogeneic bone and improve its survival rate. Second, heterogeneous bone in the application of mandibular bone graft.
