Perioral Region
Pronunciation: peh-ree-OR-al REE-jun
The anatomical area immediately surrounding the mouth, including the lips, philtrum, vermilion border, and chin.
Full Definition
The perioral region encompasses the anatomical zone around the oral orifice and is a high-priority treatment area in cosmetic dermatology for addressing rhytides, volume loss, and lip augmentation. Editors encounter the term in treatment protocols, clinical photography descriptors, and anatomical guides. It is distinct from 'perioral lines', which refers specifically to fine wrinkles in that region. Writers sometimes incorrectly use 'perioral' to mean 'lip area only'; editors should check that the intended anatomical scope is correct in context.
Usage
Usage note: Confirm the intended anatomical scope when authors use 'perioral'; it may be used loosely to mean 'lip area' rather than the full anatomical zone.
