Where should you begin suturing for complicated lesions of the lips?

• A. Vermillion border
• B. Oral mucosa
• C. Skin of lip
• D. Philtrum

Answer: (A)

Restoring lip contour starts with recreating the mucocutaneous junction where the vermillion border meets the lip skin. Beginning suturing at the vermillion border anchors the natural transition line and helps reestablish the white roll, which defines the boundary between red lip and skin. This initial alignment is essential for cosmetic symmetry and functional lip movement because if the border is not accurately recreated first, subsequent closures of deeper layers can pull tissues unevenly and produce a noticeable notch or misalignment along the lip. After the vermillion border is set correctly, you can close the deeper structures—mucosa and muscle—then the skin, ensuring a smooth, natural contour. The other surfaces (inner mucosa, external skin, or philtrum area) are important parts of the repair, but they don’t serve as the primary anchor for recreating the lip’s appearance and must follow the precise alignment of the vermillion border.
