摘要
目的旨在以颏下动脉和颏下静脉为血管蒂的颏下岛状瓣（SMIF）整复口腔缺损。方法7例口腔癌肿患者接受了口腔肿瘤切除加同侧颈淋巴清扫术，并同期行SMIF整复口腔缺损，其中1例施行了根治性颈清扫术，1例施行了保留颈外静脉的改良颈清扫术，其余5例施行了保留颈内静脉的改良颈清扫术。结果除行根治性颈清者外，6例行改良颈清者的SMIF均成活。结论SMIF血供恒定，成活可靠；其最大面积可达7cmX16cm，且活动度大，可达到距供区较远的部位，可广泛用于口腔颌面缺损的整复；因颈内外静脉系统是颏下静脉的回流通路，著作颈淋巴清扫术应保留两颈静脉系统之一及其与颠下静脉连通的中介静脉方能确保SMIF的成活。
Objective This article describes the use of the submental island flap based on the submental artery for intraoral reconstruction. Methods The submental island flap, pedicled at the intraoral defect side, was harvested and transferred through the floor of mouth into intraoral defects for immediate reconstruction in 7 patients who underwent combinedradical neck dissection with resection of oral cancer.The applicability of the flap was evaluated. Results Flap necrosis occurred in the first patient who underwent conventional radical neck dissection. All flaps survived in the remaining six patients who underwent modified radical neck dissection, in which either internal or external jugular vein system was retained. Conclusion The submental island flaps for repair intraoral defects seem practical since its vascular supply is reliable. However either internal or external jugular vein system should be retained to keep the venous drainage of the flapwhen radical neck dissection is done.[
