带血管蒂游离髂骨移植修复下颌骨缺损

TRANSPLANTATION OF THE VASCULARIZED ILIAC BONE AUTOGRAFT FOR RECONSTRUCTION OF MANDIEUTAR BONE DEFECT

下颌骨肿瘤瘤段截除后骨缺损,严重影响咬(牙合)功能及面颌部外形,必需重建修复,但有一定困难。同种异体或单纯自体骨移植、假体植入等均不能达到满意的疗效。七十年代以来,显微外科技术迅猛发展,带血管蒂肋骨移植修复下颌骨陆续有报道,但由于肋骨扁、

Microvascular anastomosis of free bone- graft had been used to repair massive mandibular bone defect following tumour resection in six patients, of them 4 were adamentinoma, one odontogenic fibroma and one primordial cyst. We used profunda iliac circumflex vessels in five patients and the ascending branch of the lateral circumflex femoral vessels in one pa- tient. All cases were Followed up for one to four years with successful and saitisfactory result both in function ane appearance. Eva- luation of the free vascularized iliac bone graft for reconstrution of massive mandibular defect was done, the applied anatomy of the blood supply of iliac crest graft and the choice of operative methods are discussed in detail.
