目的：探讨腓骨瓣再造下颌骨时血管蒂的摆放及吻合方法。方法：自１９９６年４月以来，应用腓骨（皮）瓣修复下颌骨缺损２６例。按下颌骨术后缺损范围，将其分为八类。根据每类的特点，提出血管蒂的放置，受区血管选择及吻合方法。结果：２６例腓骨（皮）瓣全部存活。血管蒂长度在４～８ｃｍ；受区动脉大多数选用颌外动脉（１９例），少数选用甲状腺上动脉（７例）；受区静脉选用面静脉９例，颈外静脉１７例。２３例为近心端腓血管与受区血管吻合，３例为逆行吻接。结论：不论下颌骨缺损类型如何，血管蒂必须置于新建下颌骨下缘或内面，并千方百计靠近受区血管，以确保吻合成功
Objective: To investigate the placement and anastomosis of vascularized pedicle when fibula flap reconstruction mandibular reconstruction. Methods: From April 1996, fibula (flap) was used to repair mandibular defects in 26 cases. Press the scope of postoperative jaw defects, divided into eight categories. According to the characteristics of each class, proposed placement of pedicles, by the choice of regional blood vessels and anastomosis. Results: All 26 fibula (flap) survived. The vessel pedicle length ranged from 4 cm to 8 cm. Most of the affected arteries used external carotid artery (19 cases), while a few selected superior thyroid arteries (7 cases). Nine cases received facial veins and 17 cases had external jugular vein. Twenty-three patients were anastomosed near the end of the vessel and vascular anastomosis, and 3 were retrograde fusion. CONCLUSIONS: Irrespective of the type of mandibular defect, the vessel pedicle must be placed on the inferior or medial face of the newly constructed mandible, and should be in close proximity to the affected vessel to ensure successful anastomosis
