It is suggested that people with swollen cheeks and round faces should use buccal fat pads to remove excess buccal fat and make their faces smaller and thinner. Intraoral incision was used in this operation, and no scar was left on the postoperative appearance. Sometimes simply removing the buccal fat pad can't completely improve the round face. At this time, it can also be performed simultaneously with other cosmetic operations, such as masseter hypertrophy resection and mandibular angle osteotomy.
