aesthetic units
Anatomical facial regions defined by natural contours and boundaries, used to guide reconstructive planning.
Full Definition
Aesthetic units are distinct anatomical regions of the face defined by natural contours, boundaries, and junction lines that create shadows and highlights. These units include the forehead, temples, cheeks, nose (with subunits), lips, chin, and periorbital areas. Understanding aesthetic units is crucial in facial reconstruction as incisions and tissue transfers should respect these boundaries to achieve natural-appearing results. When more than 50% of an aesthetic unit is involved in a defect, consideration should be given to removing the entire unit for optimal reconstruction.
Usage
Usage note: Always consider aesthetic unit principles when planning facial reconstruction procedures.
