Superficial Depiction of the Philtrum Groove on a Woman's Face

Description

Centered on the upper lip, the philtrum appears as a vertical midline groove extending from the base of the columella to the vermilion border at the Cupid’s bow. Raised philtral columns flank the depression on the right and left, converging inferiorly toward the labial tubercle while remaining medial to the nasolabial folds and superior to the oral fissure. Superiorly, the philtrum aligns with the nasal vestibule and anterior nasal spine region in surface projection, with the alae positioned laterally and the upper lip cutaneous portion transitioning inferiorly into the vermilion. Clinically, the philtrum is a landmark for evaluating and repairing cleft lip, where disruption or asymmetry of the philtral columns and Cupid’s bow guides preoperative planning and postoperative outcome assessment. Small differences matter. In unilateral cleft lip, surgeons often reconstruct a symmetric philtral ridge and central depression to restore midline aesthetics and orbicularis oris continuity, and in syndromic assessment a smooth or indistinct philtrum is a feature used in screening for fetal alcohol spectrum disorder using standardized lip philtrum guides. The surface anatomy also informs placement of local anesthetic infiltration and dermal filler, where overcorrection can blunt the philtral groove and alter the columella to upper lip relationship. Use this artwork in head and neck anatomy teaching to introduce facial surface landmarks, in plastic and maxillofacial surgery materials covering cleft lip repair, and in clinical education on dysmorphology and facial anthropometry for pediatrics and genetics. It also fits dermatology and aesthetic medicine references that discuss perioral injections and the anatomy of the Cupid’s bow and vermilion border.
