Clinical anatomy of the submental vein

This review provides a comprehensive overview of the anatomy of the submental vein, synthesizing recent findings on its development, anatomical features, course, and clinical significance. Additionally, it introduces the mylohyoid triangle, a new anatomical landmark where the submental vein, submental artery, and the nerve to the mylohyoid muscle run in parallel. As an essential structure in head and neck reconstructive surgery, the submental vein exhibits considerable anatomical variability, primarily due to its complex developmental process. This review highlights the importance of understanding the anatomy of the submental vein and performing thorough preoperative evaluations to enhance surgical success.
