Labial artery
Labial Artery
The Labial Artery is a branch of the Facial Artery that supplies blood to the lips. It is divided into two types: the Superior Labial Artery and the Inferior Labial Artery.
Anatomy[edit | edit source]
The labial artery originates from the facial artery in the region of the Angle of the Mouth. It then courses anteriorly, supplying the lips with blood.
Superior Labial Artery[edit | edit source]
The superior labial artery is larger and more significant than the inferior labial artery. It follows the upper lip, giving off several small branches to the muscles and skin. It also anastomoses with the artery of the opposite side and with the Inferior Labial Artery.
Inferior Labial Artery[edit | edit source]
The inferior labial artery arises near the angle of the mouth. It follows the lower lip and also anastomoses with the artery of the opposite side and with the Superior Labial Artery.
Clinical Significance[edit | edit source]
Knowledge of the labial artery is crucial in surgical procedures involving the lips, such as Lip Augmentation and Lip Reduction. Damage to the labial artery during these procedures can lead to complications such as bleeding, hematoma, and inadequate blood supply to the lips.
