Low insertion of columella

What it means

Insertion of the posterior columella below the nasal base.

This feature is different from a convex Low hanging columella that has a normal insertion. It may be associated with a Short philtrum, but this should be assessed and coded separately. A low insertion is best appreciated when viewed from the side.
