Vermilion, Lower Lip, Thick

Definition:

Objective: Height of the vermilion of the lower lip in the midline more than 2 SD above the mean

Subjective: apparently increased height of the vermilion of the lower lip in the frontal view

Comments:

Normal values for the height of the vermilion are available [Farkas, [1981]] but measurements are not commonly used. Most clinicians determine this feature subjectively. The lower lip is typically thicker than the upper one. The height of the vermilion of the lower lip varies among ethnic groups, and the vermilion should be compared to a population of same ethnic background. When the vermilion is thick, it is more convex and more everted than usual on profile view, but that should be assessed separately.
