Man is a longitudinal depression, located in the middle of the lip and below the columella. According to the plastic surgeon, this depression is shallow at the top and deep at the bottom. The ridges on both sides of the depression are ethnic ridges, and the ridges on both sides are roughly parallel, but the upper plane is narrow and the lower plane is slightly wider. The flat and unmanned upper lip is relatively lack of three-dimensional sense, which can be corrected by deepening the ridge in Man to Man.
The main surgical method used in this operation is to remove the connective tissue in the lower part of the upper lip, then reconstruct the orbicularis oris muscle ring internally, and then sew the skin and muscle by suture to produce a deepened person.
