Submental flap (SF) is a reconstructive technique that can be utilised for reconstruction of medium to large oral cavity defects, head and neck cancer, and pharyngocutaneous fistula. The submental artery island flap is pedicled on the submental artery and veins. The vascular pedicle has a length of up to 8cm. If it is further dissected to its origin from the facial artery, the pedicle can be lengthened by an additional 1-2cm to reach the lateral canthus and zygomatic arch. The use of SF for the reconstruction of head and neck defects has re-emerged over the past decade due to various reasons. We present a series of four case reports of head and neck cancers including a basal cell carcinoma, squamous cell carcinoma, and Merkel tumour, where the SF technique was used to successfully reconstruct the resultant facial defect. The advantages and disadvantages of the SF are discussed with a brief literature review.
颏下瓣（SF）是一种重建技术，可用于重建中到大的口腔缺损、头颈部癌症和咽皮瘘。颏下动脉岛瓣由颏下动脉和静脉供血。血管蒂长可达 8cm。如果进一步解剖至面动脉起源处，蒂可延长 1-2cm 以到达外眼角和颧弓。由于各种原因，过去十年颏下瓣在头颈部缺损重建中的应用再次出现。我们报告了 4 例头颈部癌症病例，包括基底细胞癌、鳞状细胞癌和 Merkel 瘤，其中使用 SF 技术成功重建了面部缺损。我们结合文献复习讨论了 SF 的优缺点。
