Plastic and cosmetic surgery

by Frederick Strange Kolle

1. The skin only is destroyed and the mucosa remains.

2. The mucosa has been partially destroyed with the skin, but a part of the free border of the lip remains and is attached to the cicatrix.

3. All the parts which make up the lip have been destroyed, and there remains neither skin, mucosa, muscles, nor the prolabium.

The loss of substance of varying degree may involve either of the outer thirds or the median position of the lip, or its entire structure. For a more explicit classification the author divided these defects into:

(a) Unilateral defect of the first, second, or third degree.

(b) Bilateral defect of the first, second, or third degree.

(c) Median defect of the first, second, or third degree.

(d) Total loss of upper lip.

This same classification applies to the defects of the lower lip.
