目的：腓骨游离瓣是最常见的修复瓣之一，逆行吻合游离腓骨瓣较为少见。本文探讨３例逆行吻合游离腓骨瓣修复口腔下颌骨缺损的改良手术方法及适应症。方法：自１９９６年８月至１９９７年８月内２６例腓骨瓣用于治疗下颌骨缺损，其中３例应用逆行吻合技术。结果：三例逆行吻合游离腓骨瓣全部成活，无任何并发症，术后外形理想，供区也恢复良好。结论：逆行动脉吻合游离腓骨瓣技术要求高，应严格掌握特征，静脉应仔细解剖。
Objective: Fibula free flap is one of the most common prosthetic flap, retrograde anastomosis free fibular flap is relatively rare. This article discusses three cases of retrograde anastomosis of free fibular flap to repair oral mandibular defect improved surgical methods and indications. Methods: From August 1996 to August 1997, 26 cases of fibula flap were used to treat mandibular defects, of which 3 cases were treated with retrograde anastomosis. Results: Three cases of retrograde anastomosis free fibular flap all survived without any complications. The postoperative appearance was ideal and the donor area recovered well. Conclusion: The technique of retrograde arterial anastomosis free fibular flap is high, and the characteristics should be strictly controlled. The vein should be carefully dissected.
