Aesthetic Subunit
Distinct facial regions defined by natural shadows, contours, and boundaries that guide reconstructive planning.
Full Definition
Aesthetic subunits are anatomically and visually distinct regions of the face that are delineated by natural shadows, ridges, and contours. These subunits include areas such as the nasal dorsum, nasal alae, upper and lower eyelids, and various cheek regions. In reconstructive surgery, respecting these boundaries often produces superior aesthetic outcomes compared to simple geometric closure, as scars placed along subunit borders are less conspicuous.
Usage
Usage note: Distinguish from 'anatomic subunit' which refers to functional rather than aesthetic boundaries.
