目的：对颏下岛状皮瓣修复口腔颌面部肿瘤术后缺损患者进行观察与探讨，为临床应用颏下岛状皮瓣修复治疗存在口腔颌面部肿瘤术后缺损情况的患者提供依据。方法：对2013 年6 月到2015 年6月期间在医院接受颏下岛状皮瓣修复治疗的60 例口腔颌面部肿瘤术后缺损患者进行临床回顾性研究，按照是否存在颈淋巴结转移分为两组进行研究比较。结果：研究组口腔颌面部肿瘤术后缺损患者的颏下岛状皮瓣存活率，术后复发率，术后6 个月、1 年、2 年的生存率，术后并发症总发生率，总满意度与对照组口腔颌面部肿瘤术后缺损患者相比，组间差异不明显（P＞ 0.05），不具有统计学意义。结论：使用颏下岛状皮瓣修复治疗口腔颌面部肿瘤术后缺损患者的效果较好，大多数患者对于临床修复治疗效果比较满意。而且，对存在颈淋巴结转移的患者实施颈部淋巴结的清扫术及术后放疗对于临床疗效的影响不大，基本不影响皮瓣的存活，具有重要的临床应用价值。

英文摘要:

Objective:To observe and explore submental island flaps in repairing postoperative defects of oral and maxillofacial tumor, and provide evidence for the clinical application of submental island flaps.Methods:60 oral and maxillofacial tumor patients with postoperative defects who received submental island flaps repairing in our hospital from Jun 2013 to Jun 2015 were selected and retrospectively studied. The patients were divided into two groups based on existence of cervical lymph node metastasis.Results:Compared to control group, no significant differences existed in the survival rate of submental island flaps, postoperative recurrence rate, survival rate 6 months, 1 year and 2 years after surgery, total incidence rate of postoperative complications, total satisfaction rate of study group (P＞0.05).Conclusion:Submental island flaps have a relatively good effect in repairing postoperative defects of oral and maxillofacial tumor. Most patients are satisfied with the clinical repairing results. Moreover, cervical lymph node dissection and postoperative radiotherapy conducted on patients with cervical lymph node metastasis do not have much influence on clinical repairing effect and don't affect flap survival. Submental island flaps are of important clinical application value to postoperative defects of oral and maxillofacial tumor.
