Buccal fat removal, sometimes called bichectomy, is a cosmetic procedure in which a surgeon extracts part or all of the fat pads that sit deep in each cheek. The operation itself is relatively quick and straightforward, but the decision to have it done is more nuanced than social media makes it look. The buccal fat pad plays functional roles in the face, the long-term effects of removing it are poorly studied, and not everyone is a good candidate.
What the Buccal Fat Pad Actually Does
The buccal fat pad is a biconvex pocket of fatty tissue found on each side of the face, sitting along the front edge of the masseter muscle (the big muscle you clench when you bite down). It is not just cosmetic filler. These fat pads serve as gliding surfaces that let your chewing and facial-expression muscles slide past each other smoothly, and they cushion nearby structures from the force of muscle contraction or external impact.1PubMed. Anatomical structure of the buccal fat pad and its clinical adaptations They also play a role in shaping the contour of the mid and lower face, which is precisely why people seek to have them reduced.
One thing that surprises many people considering this surgery is how much buccal fat volume varies from person to person. It correlates positively with body mass index and with age, meaning heavier individuals and older adults tend to have larger buccal fat pads.2PubMed. Changes of the Buccal Fat Pad Volume According to the Different Age Groups, Gender, and Body Mass Index: An Evaluation With Computed Tomography But even among people of similar weight and age, there is considerable variability in buccal fat pad size.3PubMed.

How the Surgery Works
Buccal fat removal is performed through the inside of the mouth, so there are no visible external scars. A surgeon makes a small incision on the inner cheek, uses blunt dissection to locate the fat pad, and then extracts it, often with gentle suction assistance.4PubMed. Buccal Fat Reduction: Indications, Surgical Techniques, Complications The incision is closed with dissolvable stitches. The entire process typically takes under an hour, and it can be done under local anesthesia, though some surgeons offer sedation.
Because the approach is intraoral, infection control matters. The mouth is a bacteria-rich environment, and surgeons generally prescribe antibiotics and a chlorhexidine rinse. Reported complications include cases where the parotid duct (the tube that delivers saliva from the parotid gland into your mouth) was damaged during the procedure, requiring follow-up surgery to create a new opening for the duct and drain the resulting swelling.5Journal of Craniofacial Surgery. Lesions of the Parotid Gland and Buccal Artery After Buccal Fat Pad Reduction In another documented case, uncontrolled bleeding from the internal maxillary artery required emergency management by an oral surgery team. These are uncommon but serious complications that underscore why surgeon experience and anatomical knowledge are not optional.
The Risks You Should Know About
The most talked-about risk is nerve damage. The buccal branches of the facial nerve and the parotid duct run in close proximity to the buccal fat pad, and the exact anatomical relationship varies from person to person. A cadaver dissection study found that in roughly a quarter of specimens, the parotid duct ran deep to the buccal fat pad extension, meaning complete removal of the fat pad in those individuals would risk injuring the duct and the nearby nerve branches.6PubMed Central. Buccal Fat Pad Excision: Proceed with Caution Consequences of such injury can range from temporary numbness or tingling to a metallic taste, facial drooping, or pain in the jaw and neck.
Temporary facial weakness (paresis) has been documented as a complication. In reported cases, it resolved over time, but the experience is distressing. Surgeons who specialize in this procedure emphasize that meticulous technique and thorough knowledge of the fat pad’s relationship to the nerve and duct are essential for prevention.7PubMed Central. Transient facial paresis as a complication of buccal fat removal
Beyond nerve and duct injury, other potential complications include asymmetry (if more fat is removed from one side than the other), hematoma, infection, and overcorrection, which can leave the face looking gaunt rather than sculpted. Overcorrection is particularly tricky because its full effect may not become apparent for years as the face ages naturally.
Who Is a Good Candidate
Not everyone with round cheeks should be looking at buccal fat removal. The ideal candidate has strong cheekbones that are obscured by prominent buccal fat, giving the lower face a heavy or overly round appearance. In people with naturally flat or underdeveloped cheekbones, removing buccal fat can produce an overcorrected, hollow look.8PubMed Central. Buccal fat pad excision for cheek refinement: A systematic review
Age and fat pad volume are critical factors. Younger patients sometimes have naturally fuller cheeks that will slim on their own as the face matures, and surgeons caution against over-excision because the natural aging process will thin the face further over time.9The American Journal of Cosmetic Surgery. Buccal Fat Pad Excision for Cheek Contouring: A Systematic Review A surgeon evaluating your candidacy should consider your bone structure, current fat pad volume, skin quality, age, and what your face is likely to look like in ten or twenty years, not just today.
Recovery After the Procedure
The initial recovery is relatively mild compared to many facial surgeries. In a prospective study tracking patients after intraoral buccal fat removal, swelling was gone by about two weeks, pain dropped significantly within the first fifteen days, and mouth opening returned to normal within a month.10The Open Dentistry Journal. Post-Operative Evaluation of the Intra-Oral Buccal Fat Pad Removal Technique: A Prospective Study During the first week, most patients eat soft foods and avoid strenuous activity. You will look somewhat puffy for the first few days, and the final contour does not show up right away because residual swelling takes weeks to fully resolve.
Because the incision is inside the mouth, you will need to be careful about oral hygiene during healing. Rinsing with an antiseptic mouthwash, avoiding crunchy or sharp foods, and not smoking are standard postoperative instructions.
The Long-Term Aging Question
This is the area where the evidence is thinnest, and it is arguably the most important consideration. A systematic review of buccal fat pad removal studies found that no study had evaluated facial aging and long-term effects, leaving the procedure’s impact on those features unclear.11PubMed Central. Buccal fat pad removal to improve facial aesthetics: an established technique? That is a significant gap in the literature for a permanent, irreversible procedure.
What we do know about buccal fat and aging suggests reason for caution. A scoping review found that buccal fat pad volume tends to increase from childhood into adulthood and may not begin to decrease until after age 60 or 70. As the face ages, the buccal fat pad descends vertically and can appear to push outward, which is why buccal fat reduction is actually one of the more common procedures performed during facelift surgery on older patients.12PubMed. How Does the Buccal Fat Pad Age and How Can it Be Managed in Facelift Surgery? A Scoping Review of the Literature and Our Proposed Algorithm In other words, nature already reduces the fullness of the buccal area over the decades. Removing fat in your twenties or thirties means accelerating a process that would happen on its own, potentially leaving the mid-face looking prematurely aged or hollow later in life.
Recent work has proposed a model of mid-face aging, termed the “Buccal Cascade,” in which weakening of the capsule surrounding the buccal fat pad leads to the fat shifting position, contributing to the sagging and volume loss people associate with an older-looking face.13PubMed. Buccal Fat Suspension: Not Just a Lift-Restoring the Foundational Anatomy of a Youthful Cheek If this model is correct, having less buccal fat to begin with could mean there is less structural support in the cheek as you age, though this remains a theoretical concern rather than a proven outcome.
Patient Satisfaction
Despite the uncertainties, most patients who choose buccal fat removal report being happy with the results in the short term. A study examining personal satisfaction found that self-perception of aesthetic need was the main reason people sought the surgery, and most patients felt the results matched or came close to their expectations.14Oral Surgery. Dimensional and anthropometric correlation analyses of buccal fat pad and patient’s personal satisfaction after buccal fat pad excision
A clinical trial that tracked quality-of-life and facial-appearance satisfaction scores found significant improvement at one month. But it also flagged something worth noting: patients over 25 showed a decline in satisfaction by the end of the study period.15PubMed. The impact of partially removing the Bichat fat pad in the linear facial measurements, satisfaction with facial aesthetics and quality of life: a single-arm CONSORT-guided clinical trial The reasons for that decline are not entirely clear, but one plausible explanation is that older patients may start to see the effects of volume loss becoming less flattering as their face continues to mature. It is a small signal in a single study, but it aligns with the broader concern about long-term aging effects.
Non-Surgical Alternatives for Face Slimming
If permanent fat removal feels too aggressive, there are non-surgical approaches that can create a slimmer facial contour, though each has its own limitations.
- Injectable fillers: Strategically placed dermal fillers in the cheekbones and mid-face can create the illusion of a more sculpted lower face without removing any tissue. Anatomical-based filler techniques offer a precise approach to cheek contouring and are considered safe when performed by experienced injectors.16PubMed. Anatomical-Based Filler Injection Techniques: Anteromedial, Buccal, and Lateral Cheek Hollow The effect is temporary, lasting anywhere from six months to two years depending on the product, which can be either a drawback (repeated costs) or an advantage (reversibility).
- Deoxycholic acid injections: This injectable dissolves fat cells and is FDA-approved for submental fat (under the chin). Some practitioners have explored using it off-label in the buccal area, though evidence for that specific use is limited. A meta-analysis of deoxycholic acid for submental fat found it was effective, but came with a long list of side effects including swelling, numbness, pain, redness, itching, nodules, and a higher risk of fibrosis (hardened tissue).17PubMed Central. Efficacy, safety, and potential industry bias in using deoxycholic acid for submental fat reduction ‒ A systematic review and meta-analysis of randomized clinical trials The recovery from these injections is not trivial, with significant swelling lasting days to weeks.
- Energy-based devices: Technologies like radiofrequency, ultrasound, cryolipolysis, and laser therapy have been shown to reduce fat in treated areas, with measurable decreases in fat layer thickness and positive patient satisfaction scores.18PubMed. Noninvasive lipolysis modalities in aesthetic medicine Radiofrequency in particular has been studied for facial and submental fat reduction, with results lasting at least six months after treatment.19PubMed. Evaluation of safety and efficacy of noninvasive radiofrequency technology for submental rejuvenation These devices produce more subtle changes than surgery and generally require multiple sessions.
- Botox in the masseter: This does not target the buccal fat pad at all, but it is worth mentioning because many people confuse a wide jaw (from enlarged masseter muscles) with chubby cheeks. Botox injections into the masseter can slim the lower face by reducing muscle bulk. If your fullness is muscular rather than fatty, this may address the concern more appropriately than buccal fat removal.
Can Buccal Fat Removal Be Reversed?
In practical terms, no. Once the fat pad is removed, it does not grow back. If a patient is unhappy with the result years later, the most common corrective approach is fat grafting, where fat is harvested from another part of the body and injected into the cheeks to restore volume. This is a separate surgical procedure with its own recovery, unpredictability (some of the grafted fat is reabsorbed by the body over time), and costs. It can improve hollowness, but it does not recreate the specific structural role the buccal fat pad played. The irreversibility is one of the strongest arguments for being conservative about how much fat is removed and for being sure you are a good candidate before proceeding.
Why the Buccal Fat Pad Matters in Infancy
An interesting piece of biology that does not come up in most cosmetic surgery discussions: the buccal fat pad in newborns contains brown adipose tissue, a special type of fat that generates heat. Researchers have hypothesized that this brown fat helps warm the chewing muscles in infants, preparing them for the energy-intensive act of suckling. Animal studies have shown that disrupting brown fat in the facial area impairs sucking ability, and clinical observations show that sucking efficiency improves during the first month of life, when brown fat is present in the buccal pad.20PLOS ONE. Brown Adipose Tissue in the Buccal Fat Pad during Infancy By adulthood, this brown fat has largely been replaced by white fat, which is the type being removed in buccal fat surgery. But it is a reminder that these fat pads evolved to serve real purposes, not just to shape the contour of your cheeks.
Partial Versus Complete Removal
Surgeons increasingly favor partial removal over taking out the entire buccal fat pad. The reasoning is straightforward: partial removal gives a subtler result with a lower risk of the gaunt, overcorrected look that can develop with age. Many of the patient-satisfaction studies that reported good outcomes used a partial excision approach, removing only enough fat to reduce cheek fullness while leaving structural support intact.
Complete removal carries a higher risk of nerve and duct injury simply because the surgeon has to dissect deeper and more extensively. The cadaver study finding that roughly a quarter of people have anatomy placing the parotid duct in the danger zone during total removal makes a strong case for the conservative approach.6PubMed Central. Buccal Fat Pad Excision: Proceed with Caution A surgeon who suggests removing the entire pad without explaining why should prompt a second opinion.
Choosing a Surgeon
Buccal fat removal sits in an unusual gray zone where oral surgeons, maxillofacial surgeons, plastic surgeons, and even some dermatologists perform the procedure. The intraoral approach means it technically falls within the scope of practice for providers trained in oral surgery, but the aesthetic judgment required goes beyond surgical skill. A technically perfect excision can still produce a bad result if the wrong amount of fat is removed from the wrong candidate.
When evaluating a provider, look for board certification in a relevant surgical specialty, before-and-after photos of patients who look similar to you in age and facial structure, and a willingness to tell you if the procedure is not appropriate for your face. Surgeons who perform facelifts and mid-face procedures tend to have the deepest understanding of how buccal fat removal interacts with long-term facial aging. Be wary of anyone who treats the procedure as purely cosmetic and glosses over the aging considerations, since the risks of buccal fat removal are largely about what happens ten or twenty years later, not in the first month.
The procedure is not especially expensive compared to other facial surgeries, typically running a few thousand dollars. Because it is purely cosmetic, insurance does not cover it. That affordability, combined with its short recovery time and social media visibility, has made it one of the trendier procedures in recent years. Trends in cosmetic surgery come and go, though, and the faces that look fashionable today may not be the ones people want in a decade. A permanent, irreversible procedure is a poor way to chase a trend.
