“Bichat’s” fat is a deep fat in the buccal cavity (middle part). The purpose of this fat is to help babies breastfeed, upon grow up – to protect the muscles from excessive friction during chewing movements, and the face nerves and muscles – from mechanical damage.

This fat is unique because it is not affected by body weight changes. As the child grows, fat functionality diminishes until it lastly becomes meaningless and performs no function, but the fatty tissue remains. For many men and women, this fat is unnoticeable, but for some “Bichat’s” fatty tissues develop too much genetically, resulting in a plumper, larger, slightly sagging face, a visually larger lower jaw that remains the same even after getting rid of excess weight. It is important not to confuse this fat with the subcutaneous fat layer of the face that develops in case of overweight and may reduce after the weight loss.

How the surgery is performed?


This is a simple surgery that lasts about an hour. During the surgery, a small incision in the mucous membrane of the mouth is made, through which some of the fat released from the cheeks is removed. The incision is usually stitched with absorbable sutures, which are absorbed over time and do not need to be removed. The surgery, according to the needs of a patient, may be performed under both local and general anesthesia.


Postsurgical period and healing



  • For 1-2 weeks after the surgery, the severe physical exertion should be avoided;

  • Extremely hot and hard food should be avoided for several days after the surgery;

  • The scars do not remain after the surgery because the incision is made inside the oral mucosa;

  • Swelling starts to subside after a couple of weeks;

  • The final result - highlighted cheekbones, clearer jaw line, more oval and smaller face shape and less round cheeks - can be enjoyed after 2-3 months.
