微血管游离皮瓣移植时行神经吻合对于感觉功能的恢复非常重要,薄而小的未吻合神经移植物能恢复一定感觉,但高级辨别能力恢复仍需神经吻合。颌面部缺损行背阔肌皮瓣移植时有两种神经吻合技术:用肋间神经皮支和用胸脊神经。本研究目的是评价行与不行神经吻合移植物组织学和神经感觉功能的差异及确定移植神经来源对感觉功能康复的影响。 材料和方法 研究对象是54位口腔鳞状细胞癌患者,在肿瘤广泛切除后行同侧颈淋巴清扫,面部缺损行微血管背阔肌皮瓣移植。其中15位不行神经吻合,21位以胸脊神经吻合,18位以肋间神经皮支吻合。术中、术后制作组织切片,评价神经束数
Microvascular free flap anastomosis nerve graft for the recovery of sensory function is very important, thin and small non-coincident nerve grafts can restore some feeling, but the recovery of advanced discrimination still need nerve anastomosis. Maxillofacial defects in the latissimus dorsi flap transplantation when there are two nerve anastomosis techniques: with intercostal nerve sheath and thoracic spinal nerve. The purpose of this study was to evaluate the differences in histological and neurosensory functions between anastomosed and non-anaged grafts and to determine the effect of transplanted neural sources on the recovery of sensory function. MATERIALS AND METHODS: Fifty-four patients with oral squamous cell carcinoma underwent resection of ipsilateral neck lymph nodes after extensive resection of the tumor and flap of the microvasculature latissimus dorsi flap. Among them, 15 were not anastomosed nerves, 21 were anastomosed with thoracic spinal nerves, and 18 were anastomosed with intercostal nerve sheaths.
