摘要目的 探讨颏下岛状皮瓣修复舌癌术后次半舌缺损的临床效果.方法 2015年6月至2017年11月,对天津市口腔医院颌面外科收治的16例舌癌术后次半舌缺损患者,采用颏下岛状皮瓣进行修复.根据缺损情况在颏下区设计并制备以颏下动脉为血管蒂携带二腹肌前腹的组织瓣,经下颌舌骨肌隧道转移至缺损区,修复缺损.结果 16例皮瓣完全成活,皮瓣大小3.0 cm×4.0 cm～4.5 cm×7.5 cm.所有患者均获得3～24个月随访,肿瘤局部无复发,舌体形态良好,未出现死亡病例.所有随访患者进食正常,言语清晰,抬头无受限,对舌形态及颏部外形满意.结论 颏下岛状皮瓣修复舌癌术后次半舌缺损是一种安全可靠的方式,皮瓣易成活,供区瘢痕少,可有效恢复舌体外形,改善口腔功能.

abstractsObjective To discuss the clinical outcome of submental island flap used in reconstruction of nearly half tongue defect after resection of tongue cancer.Methods From June 2015 to November 2017,16 submental island flaps were used to reconstruct nearly half tongue defect after resection of tongue cancer.Tissue flap with submental artery as vessel pedicle and suitable for the defect with anterior belly of digastric muscle was prepared in submental area and transferred to the defect area through the mandibular hyoid muscle tunnel to repair the defect.Results All submental flap transfers were successful.The areas of flaps were 3.0 cm×4.0 cm-4.5 cm×7.5 cm.No local recurrence of tongue SCC was found and no death was noted during 3-24 months of follow-up.The functional and esthetic result such as feeding,speeching,head raiseing were satisfied for patients.Conclusions Higher success rate and scars decrease make submental island flap an reliable choice for reconstruction of nearly half tongue defect after resection of tongue cancer.It can restore appearance of tongue and improve oral function effectively.
