Dimple shaping is generally not too painful. Generally, the method of suture is adopted, and the muscle and dermis are directly connected with silk thread at the position of buccal fossa to form a dimple. It is simpler and faster, and a pair of dimples usually takes only a few minutes to complete. Incision method is to make a vertical incision with a length of 2 cm on the buccal mucosa in the oral cavity, and sew a needle between some muscles and dermis in the incision to form a shallow recess on the corresponding skin. Although this operation is complicated, the effect is positive.
