包含颈外静脉的颈阔肌肌皮瓣修复口腔癌切除后缺损

目的探讨将颈外静脉包含在颈阔肌肌皮瓣内修复口腔癌切除后缺损的手术方法。方法先形成蒂在颌缘下包含颈外静脉的颈阔肌肌皮瓣，待口腔肿瘤切除后，将肌皮瓣经口底隧道引入口腔修复缺损。结果临床应用17例，肌皮瓣均无血运障碍，100％存活，其中有2例发生口面痿，经换药后痿口完全闭合。结论将颈外静脉包含在颈阔肌肌皮瓣内有助于肌皮瓣血循环的改善和存活率的提高。

Myocutaneous platysma flap containing external jugular vein for the oral reconstruction after cancer excision

Objective To improve the blood circulatiou of myocutaneous platysma flap and its survival rate. Methods There were seventeen oral cancer patients in this group. After the tumor excision, the oral defect was reconstructed with myocutaneous platysma flap which had submandibular pedicle and contained external jugular vein. Results There was no any circulation compromise in this group. The survival rate of the flap was 100%. Two cases encountered oral-facial fistula but were cured by dressing change. Conclusious Preserving and containing the external jugular vein in the flap is helpful for improving the blood circulation of the myocutaneous platysma flap and making its survival rate higher.
