The Location of the Tubercle of the Upper Lip in a Black Female

Description

Centered on the midline of the upper lip, the labial tubercle sits within the vermilion (vermilion zone) just inferior to the philtral dimple and between the paired philtral columns that run up toward the base of the columella. Its rounded prominence is bordered laterally by the peaks of the Cupid’s bow and transitions inferiorly toward the oral fissure, with the lower lip and labiomental region providing contrast in the anterior view of the mouth. A blue surface marker isolates this focal point against surrounding landmarks such as the nasal ala, nasolabial fold, and bilateral oral commissures. Clear midline anatomy. Accurate localization of the upper lip tubercle matters in facial plastic and reconstructive planning because it anchors perceived symmetry of the vermilion and helps define the central lip contour at conversational distance. During cleft lip repair or secondary revision, surgeons often aim to recreate the central tubercle while restoring philtral column alignment and vermilion height, since small errors in the midline are amplified by the Cupid’s bow. Injectable procedures also depend on this map: hyaluronic acid placed too lateral can flatten the tubercle and widen the central lip, while overfilling the midline can obscure the philtrum and distort the white roll at the vermilion border. Use this rendering in anatomy and head and neck surface anatomy teaching to label the philtrum, Cupid’s bow, vermilion border, and labial tubercle on a Black female face, supporting inclusive instruction and patient education materials for lip augmentation, cleft care, or scar revision consultations. It also fits well in textbooks and surgical atlases discussing lip aesthetics, vermilion advancement, and incision planning around the philtral subunits.
