Hello, dimple reconstruction is considered to be a mature technology in plastic surgery, which mainly connects the dermis and smiling muscle through surgery to form a depression at a specific position. At present, there are two commonly used methods, namely suture and intraoral incision. There are sewing methods in which muscles and dermis are connected by silk thread to form a dimple at the position of buccal fossa, and cutting methods in which buccal mucosa is cut and removed at the fixed point of the dimple.
