原发灶对侧颏下岛状皮瓣整复口腔颌面部缺损的临床应用

Study on the clinical application of contralateral primary tumor submental island flap to reconstruct oral and maxillofacial defects

目的探讨用原发灶对侧颏下岛状皮瓣整复舌及口底缺损,丰富口腔颌面部缺损的整复方法。方法选取5例舌及口底肿瘤切除术后缺损,用对侧颏下岛状皮瓣进行整复,观察疗效。结果原发灶对侧颏下岛状皮瓣有足够的血管蒂到达对侧口底舌腹,修复皮瓣全部成活。结论原发灶对侧颏下岛状皮瓣切取简单,手术时间短,成活率高,供区再次损伤畸形小,不影响根治,有望成为舌口底恶性肿瘤切除后即刻修复常规皮瓣。

Objective To explore the method that uses primary tumor contralateral submental island flap to reconstruct tongue and floor of mouth defects.Methods Selected 5 cases that used primary tumor contralateral submental island flap to reconstruct tongue and floor of mouth defects after tumor resection,and observed the clinical efficacy.Results The submental island flap has a long pedicle,which can reach contralateral tongue and floor of mouth if required.All flaps were survived postoperative.Conclusion Contralateral primary tumor submental island flap has many features include：Easy obtaining and high survival rate with minimal donor site morbidity.It does not affect the radical,so it will be an ideal material for repairing tongue and floor of mouth defects.
