摘要
A consensus on facial artery anatomy has not been established due to the discrepancies in previous studies.The authors sought to assess the branches, course, and location of the facial artery in Asians by utilizing computed tomographic angiography.The computed tomographic angiography images of 300 facial arteries from 150 Asian patients were evaluated. The FA was classified as follows: type 1, facial artery terminates superior labial or inferior labial artery; type 2, facial artery terminates lateral nasal or inferior alar artery; type 3, facial artery terminates medial canthal artery; or type 4, facial artery is divided into duplex branches with dominant medial canthal artery laterally. The relationship between nasolabial fold and FA was evaluated, and the distances from anatomical landmarks to FA were measured to position the course.Seventy (23.3%), 163 (54.3%), 49 (16.3%), and the other 18 arteries (6.0%) were classified as type 1, 2, 3, and 4, respectively. A total 72.3% of facial arteries were located medially to the nasolabial fold, and only 14.7% of arteries were lateral to the nasolabial fold. The vertical distance between the facial artery and the inner canthus or the midpoint of the inferior orbital rim decreased from type 1 to type 4 facial artery (P < 0.0001). The 4 types did not significantly differ in distance between the mandibular angle (P = 0.1226) or oral commissure (P = 0.1030) and the facial artery at inferior of mandible.Detailed findings of the facial artery will provide a valuable reference for filler injection in cosmetic procedures and flap design in reconstructive surgery.
