Bone defects in the maxillofacial region after ablative surgery require reconstructive surgery, usually using microvascular free flaps. This paper presents a new method of reconstructing extensive defects in patients not suitable for microvascular surgery using prefabrication of a vascularised osteomuscular flap from the scapula or iliac crest bone.
Three patients who were treated with this new technique are presented. Two patients (one mandibular defect and one defect in the maxillary region) received prefabricated osteomuscular flaps from the iliac crest bone using the latissimus dorsi muscle as a pedicle. One patient also presenting a mandibular defect after tumour surgery received a scapula transplant for reconstruction of the defect using the pectoralis major muscle as pedicle.
In all three cases vital bone could be transplanted. The pedicle was strainless in all three cases. Minor bone loss could be seen initially only in one case. The results are stable now and one patient received dental implants for later prosthetic treatment.
The presented two-step surgery provides an excellent method for reconstruction of bony defects in the maxillofacial region in patients where microvascular surgery is not possible due to reduced state of health or lack of recipient vessels.
颌面区域切除术后的骨缺损需要进行重建手术,通常采用游离微血管皮瓣。本文介绍一种新方法,即通过预制来自肩胛骨或髂嵴骨的带血管化骨肌皮瓣,为不适用于微血管手术的患者重建大面积缺损。
介绍了3例采用该新技术治疗的患者。2例患者(1例下颌骨缺损,1例上颌区域缺损)接受了以背阔肌为蒂的来自髂嵴骨的预制骨肌皮瓣。1例肿瘤手术后出现下颌骨缺损的患者接受了以胸大肌为蒂的肩胛骨移植以重建缺损。
所有3例均成功移植了有活力的骨组织。3例患者的蒂部均无张力。最初仅1例出现轻微骨质流失。目前结果稳定,1例患者接受了种植牙以便后续进行修复治疗。
所介绍的两步手术为因健康状况不佳或缺乏受区血管而无法进行微血管手术的患者提供了一种出色的颌面骨缺损重建方法。
