vermillion border
Pronunciation: ver-MIL-ee-un
The distinct junction between the red portion of the lip and the surrounding facial skin, crucial for aesthetic lip reconstruction.
Full Definition
The vermillion border is the anatomical transition zone that forms the edge between the red lip (vermillion) and the normal facial skin. This border is critical in plastic surgery procedures involving the lips, as any disruption or asymmetry is highly visible and aesthetically displeasing. Proper restoration of this border is essential in cleft lip repairs, trauma reconstruction, and cosmetic lip procedures to achieve natural-appearing results.
Usage
Usage note: Always lowercase unless at sentence beginning; refers specifically to the border, not the vermillion tissue itself.
