PY - 2013 T2 - Facial Flap Surgery AB - The cheek extends medially from the nasolabial fold and nasofacial sulcus laterally to the preauricular sulcus. Superomedially, the cheek ends at the infraorbital crease and laterally at the zygomatic arch. The inferolateral border is the margin of the mandible. The cheek is a convex structure in youth and often develops an inferolateral concavity with age consequent to volume loss. The skin is generally nonsebaceous. In men, the lateral and inferior cheek bares dense terminal hair. In youth, the medial border of the cheek with the upper lip lateral subunit is indistinct, but with age a visible nasolabial fold develops. The nasofacial sulcus is a concave deflection which defines the shape of the nose, and ablation of which leads to asymmetry.
