2) disinfection. Disinfect skin and mouth with 1‰ bromogeramine, and spread sterile towels.
3) anesthesia. Local infiltration anesthesia was performed at a fixed point in the dimple to reach the corresponding buccal mucosa.
4) surgery. Thread 1 silk thread into the needle from the skin with a large arc triangular needle, and the needle will be discharged from the corresponding buccal mucosa. Leave one end of the thread in the mouth first, then take out the needle, and insert the thread left outside the skin into the big arc triangular needle. A large arc-shaped triangular needle with a belt line enters the skin along the original needle eye and walks in the dermal layer of the skin for 2 ~ 3 mm, then penetrates into the subcutaneous layer and passes through the needle outlet of the original mucosa for 2 ~ 3 mm, and then pulls the needle and thread, thus forming a dimple.
5) suture. Put a piece of iodoform gauze between the two lines in the oral cavity and tie the two lines, so that the dermal layer of the skin adheres to the buccal mucosa to form dimples.
6) nursing. After 7 ~ 8 days, cut the suture in the mouth and take out the iodoform gauze to form dimples.
