目的　探讨带血管蒂颏下皮瓣在软腭癌切除后软腭贯通缺损修复中的应用。　方法　软腭癌切除后致软腭部分或全部贯通缺损 10例 ,用颏下皮瓣一期修复。　结果　 6例皮瓣全部成活 ,2例皮瓣远端部分裂开坏死 ,2例完全坏死。　结论　颏下皮瓣在修复软腭缺损中 ,具有距离近 ,供瓣区隐蔽 ,厚薄适中 ,血供可靠 ,操作方便等优点 ,术后形态恢复较满意 ,是修复软腭缺损的一个理想选择。术中保留颈外静脉进入皮瓣的变异分支有利于保证皮瓣的静脉回流 ;处理好皮瓣鼻腔侧创面是修复成功的关键 Objective To investigate the application of vascular pedicle submental flaps in the repair of soft palate through the soft palate. Methods Ten cases of soft palate partial or total penetrating defect after excision of soft palate cancer were repaired by submental flap. Results All the flaps survived in 6 cases. The distal part of the flap was dehiscent and necrotic in 2 cases and completely necrotic in 2 cases. Conclusions The submental flap is an ideal choice for repairing the soft palate defect. It has the advantages of close distance, concealed flap area, moderate thickness, reliable blood supply and convenient operation. Intraoperative preservation of the jugular vein into the varicose branch of the flap is conducive to ensuring the flap venous return; to deal with flap nasal cavity flap is the key to successful repair
