分析2006年11月～2012年6月共21例非血管化髂骨游离移植修复下颌骨缺损的病例,术后进行疗效观察,包括移植骨块存活、移植骨吸收程度、颌骨左右外形轮廓、咬合关系、咀嚼功能、张口度等;对比分析成活和失败病例:从下颌骨缺损类型、受植区软组织情况、移植骨块游离时间、患者全身状况进行研究,分析失败病例发生的原因,并提出相应的预防措施。在术后6个月～2年的随访中,18例下颌骨缺损获得修复,功能及美观均满意,其移植成活率为85.7%;3例感染(14.3%),其中2例移植骨块去除、修复失败,1例恶性肿瘤复发,移植骨修复失败。自体非血管化髂骨移植修复部分下颌骨缺损是一种重建其功能和外形的简单有效的方法。
From November 2006 to June 2012, a total of 21 cases of non-vascularized iliac free grafts were repaired. The curative effect was observed after operation, including the survival of transplanted bone, the degree of bone resorption, the left and right contour of the jaw, Occlusion, masticatory function, mouth opening, etc .; Comparative analysis of survival and failure cases: the type of mandibular defect, the soft tissue by the situation, the free bone graft time, the patient’s general condition to study the causes of failure cases, and put forward Corresponding precaution. During the follow-up of 6 months to 2 years after surgery, 18 cases of mandibular defects were repaired, with satisfactory function and aesthetics. The survival rate was 85.7% and 3 cases were infected (14.3%), of which 2 cases were removed , Failed to repair, one case of malignant tumor recurrence, failed to repair bone graft. Autologous non-vascularized iliac bone graft repair of partial mandibular defects is a simple and effective method to reconstruct its function and appearance.
