The mucosa of 1- 1.5cm was cut horizontally in the arrangement of posterior teeth, and the buccal fat pad cyst was found by horizontal incision and longitudinal separation. The buccal fat pad was properly removed, which was gentle and accurate in hemostasis. Surgery usually takes 10 to 15 minutes. The ability of the mouth and lips may be temporarily weakened. The incision suture of the suture mouth is generally absorbed in about 10 days. Any facial plastic surgery may make you feel better and look more beautiful in a short time. But we must pay attention to safety and control risks. It is solemnly emphasized here that the removal of buccal fat pad can not be done in an informal plastic surgery hospital, and an experienced surgeon must be found.
