The central maxim of lip laceration repair is preservation of the vermilion-cutaneous border. This means, ensuring the pink contour of the lip remains perfectly aligned.
Technique
The first suture should precisely align the vermillion border.
Use a surgical marking pen to define the vermillion border on either side of the laceration prior to the direct injection of local anesthetic which may distort the wound.
Use a simple interrupted epidermal suture with 6-0 non-absorbable suture (ex. nylon) for the first suture.
After ensuring that this suture is correctly placed, further simple interrupted sutures can be used to bisect the wound to facilitate a well aligned & cosmetic closure.
