Tubercle of the Upper Lip, Anterior View

Description

Centered in an anterior close-up of the midface, the upper lip tubercle forms a gentle midline fullness on the vermilion of the labium superius, immediately inferior to the philtrum and its paired ridges (philtral columns). The Cupid’s bow peaks lie superolateral to the tubercle along the vermilion border (white roll), with the labial mucosa turning posteriorly toward the oral vestibule. Cutaneous landmarks of the subnasal region, including the philtral dimple and the transition from skin to vermilion, are rendered with clear contrast against a neutral background. Plastic and reconstructive surgeons pay attention to this midline anatomy because the tubercle and philtrum are primary determinants of upper-lip symmetry, and small asymmetries become obvious in frontal view during speech and smiling. After cleft lip repair, revision planning often references restoration of the philtral columns and appropriate central vermilion bulk, while overcorrection can blunt the Cupid’s bow or create a conspicuous central “beak.” Aesthetic injectors also use these surface cues when placing hyaluronic acid filler into the vermilion to avoid distorting the tubercle or crossing the vermilion border, and when counseling patients about normal variation across individuals and skin types. Small details matter. Use this asset in head and neck anatomy teaching to anchor terminology such as vermilion, philtrum, Cupid’s bow, and labial tubercle, and in clinical skills modules that cover facial examination, cleft lip phenotyping, and preoperative marking for cheiloplasty. It also fits medical publishing needs for dermatology and aesthetics topics, including herpes labialis localization along the vermilion border and differential diagnosis of midline lip lesions.
