Which artery is primarily utilized in the nasolabial flap procedure?

• A. Facial artery
• B. Angular artery
• C. Maxillary artery
• D. Submental artery

Answer: (B)

The nasolabial flap procedure primarily utilizes the angular artery, which is a branch of the facial artery. The nasolabial flap is a versatile skin flap that is commonly used for reconstructive purposes in the region around the nose and mouth, taking advantage of the blood supply from the angular artery. This artery provides important vascularity to the skin in the nasolabial area, ensuring that the flap remains viable after being elevated from its original site. In the context of the other options, the facial artery does contribute to the overall vascularization of the facial region, but it is the angular artery specifically that provides the main blood supply to the nasolabial flap. The maxillary artery is primarily associated with deeper structures and does not directly supply the skin in the nasolabial region. The submental artery, while involved in supplying the chin and lower lip areas, does not play a significant role in the blood supply of the nasolabial flap either. Therefore, the angular artery is the most vital artery in this procedure, highlighting its importance in surgical planning and execution for optimal flap survival.
