舌骨下肌筋膜瓣修复口腔癌术后缺损的应用初探

A Primary Investigation of the Infrahyoid Myofascia Flaps for Reconstruction of Defect from Oral Cancer Resection

目的 探讨舌骨下肌筋膜瓣修复口腔癌术后缺损的可行性和优缺点。方法 15例口腔癌、口咽癌患者在常规行根治术后采用舌骨下肌筋膜瓣修复术后缺损 ,并对其进行 0 5～ 5 0年的临床随访。结果 15块舌骨下肌筋膜瓣全部成活 ,颈部取瓣切口采用常规颈淋巴清扫切口 ,术后颈部切口均一期原位关闭。结论 舌骨下肌筋膜瓣修复口腔癌术后缺损具有成活率高、颈淋巴清扫切口不受取瓣影响、可直接关闭颈部切口等优点 ,但因舌骨下肌筋膜瓣组织量少、筋膜菲薄、术后有部分挛缩 。

Objective To invenstigate the feasibility of infrahyoid myofascia flaps (IMF) for reconstruction of oral cavity defect from oral cancer resection. Methods Defects of 15 cases, with oral cancer/oropharygeal cancer, were respectively repaired by IMFs, after combined radical resection had been performed. Results All 15 IMFs survived, and all incisions of neck region were primarily healing. Conclusion IMFs, for reconstruction of oral cavity defect from resection of oral cancer, have the virtue of high survival rate, directly closed incision and primary healing, but IMFs have a little volume, thin fascia, and may cause contraction. Therefore, IMFs are suitable for small defects of oral cavity.
