Facial aesthetic units
The face consists of 6 major aesthetic units comprised of: forehead, eye/eyebrow,nose, lips, chin, and cheek . These aesthetic units can be subdivided into additional anatomical subunits.For example, the nose can be divided into nasal tip, dorsum, columella, soft-tissue triangles, sidewalls, and nasal alar regions. Correct orientation of planned incisions next to these mobile functional and aesthetic facial structures is important to avoid distortion when closing wounds.
1- Forehead unit (1a central subunit; 1b lateral subunit 1c eyebrow subunit)
2- Nasal unit
3- Eye lid units (3a lower lid unit; 3b upper lid unit; 3c lateral canthal subunit; 3d medial canthal subunit)
4- Cheek unit (4a medial subunit; 4b zygomatic subunit; 4c lateral subunit; 4d buccal subunit)
5- Upper lip unit (5a philtrum subunit; 5b lateral subunit; 5c mucosal subunit)
6- Lower lip unit (6a central subunit; 6b mucosal subunit)
7- Mental unit
8- Auricular unit
