Direct answer
Buccal fat removal, or bichectomy, removes part of the deep cheek fat pad through an incision inside the mouth. It is not a weight-loss procedure; suitability depends on the whole-face distribution of fat, muscle, bone and skin.
Buccal fat removal, also called bichectomy, removes part of the deep buccal fat pad through an incision inside the mouth. Its purpose is to reduce selected lower-mid-cheek fullness. It is not a weight-loss procedure, does not directly create a jawline and cannot promise a “V-shaped” face or more prominent cheekbones.
Cheek shape is not determined by the buccal fat pad alone. Subcutaneous fat, the masseter muscle, cheekbone and chin projection, skin thickness, facial asymmetry and future ageing are assessed together. Photographs may support an initial discussion, but the amount—if any—to reduce cannot be decided without facial and intraoral examination.
| Finding | Relevance to buccal fat removal |
|---|---|
| Stable, distinct lower-mid-cheek fullness | May be assessed after other causes are considered |
| An already narrow or thin face | May be unsuitable because of hollowing or an aged appearance |
| Weight fluctuation or general facial fullness | Weight stability and whole-face distribution should be reviewed first |
| Asymmetry, previous facial surgery, nerve or salivary-duct concern | Requires more detailed anatomical and medical assessment |
A 2025 meta-analysis found substantial heterogeneity among the available studies and advised caution because of safety concerns and limited predictability. A 2026 systematic review found reports of high short-term satisfaction, but most evidence was low-level and follow-up was too limited to assess long-term ageing effects well. These studies cannot predict one patient’s complication risk or guarantee a long-term aesthetic outcome.
Swelling, pain, temporary limitation in opening the mouth and asymmetry may occur. Less common but important risks include bleeding, infection, persistent sensory change, injury to a salivary duct or facial-nerve branch, fluid collection, too little or too much change and revision surgery. Although the incision is intraoral, internal healing and scar tissue still occur; “scar-free” or “very comfortable recovery” cannot be guaranteed.
Buccal fat is part of deep facial volume, and removed tissue does not simply return to its original state. Facial fat and bone volume continue to change with age, so the possibility of a hollow or prematurely aged appearance should be discussed, especially in a thin face. The operation should not be treated as an easily reversible trial.
If fullness is mainly related to the masseter muscle, chin projection, superficial fat or skin laxity, a different or non-surgical option may be discussed. Ask:
Individual suitability and surgical scope require medical history and examination.
No. An already thin or narrow face, changing weight, marked asymmetry, impaired healing risk or another cause of fullness may make it unsuitable. Evidence about long-term ageing effects also remains limited.
In addition to swelling, pain, limited mouth opening and asymmetry, risks include infection, bleeding, injury to a salivary duct or facial-nerve branch, persistent sensory change, too much or too little volume reduction and possible revision.
