The buccal fat pad, also known as the buccal fat body, is an anatomical structure composed of deep fat located in the cheek area. Although it is widely discussed in the aesthetic and cosmetic surgery field, many people still do not fully understand its real biological function. Knowing when bichectomy—the surgery to remove it—is actually indicated is vital to avoiding long-term aesthetic issues.
In this article, you will clearly understand what the buccal fat pad is, its role in the face, and the key considerations before undergoing this procedure.
What Is the Buccal Fat Pad?
The buccal fat pad is a specialized, deep fat structure positioned between the complex facial muscles of the midface. Specifically, it rests near the buccinator muscle and the posterior region of the maxilla.
Unlike superficial fat, which sits directly beneath the skin, this tissue has an important structural function. It is located in a delicate anatomical area, close to critical structures such as branches of the facial nerve and the parotid duct. This distinct structure was first described by the French anatomist Xavier Bichat and has since played a significant role in modern facial anatomy.
What Is the Function of the Buccal Fat Pad?
The buccal fat pad is not just “excess fat” that serves no purpose—it performs important functions in the human body:
Infant Suction: It assists in the act of suction, which is especially essential in infants during breastfeeding to prevent cheek collapse.
Gliding Pad: It acts as a gliding pad that facilitates smooth muscle movement during chewing and speaking.
Volume Control: It contributes significantly to the volume and contour of the lower third of the face.
In other words, it is a highly functional structure, not just an aesthetic one. Understanding its mechanical nature changes how we approach its modification.
What Is Bichectomy?
Bichectomy is a surgical procedure that involves the partial removal of the buccal fat pad for aesthetic purposes. The main goals of the procedure include:
Slimming the mid-to-lower face.
Enhancing jawline definition.
Highlighting the cheekbone (malar) area.
When properly indicated by a skilled professional, removing part of the buccal fat pad can provide a more defined and harmonious facial appearance.

Risks and Important Considerations
Although it is considered a relatively simple procedure, reducing the buccal fat pad requires careful planning and proper patient selection. Excessive removal of this deep fat can lead to several complications over time.
The Problem of Premature Aging
The main concern with removing the buccal fat pad is how the face evolves over decades. Natural aging already involves a progressive loss of facial volume, bone resorption, and fat atrophy.
[Excessive Removal of Fat] ---> [Loss of Structural Foundation] ---> [Hollow, Aged Appearance Over Time]
If a surgeon removes too much of the buccal fat pad, it can cause:
Premature aging of the midface.
A hollow, gaunt, or sunken facial appearance over time.
An overall loss of facial harmony and vitality.
Removing too much fat can accelerate the visible aging process, leaving the patient looking older than their actual age.
Current Trend: A More Conservative Approach
Today, the trend in facial aesthetics is increasingly conservative. Many international experts believe that preserving facial volume is more beneficial than removing important deep structures.
The current focus is on:
Maintaining natural, soft results.
Avoiding overcorrection and gaunt features.
Preserving the long-term integrity of the facial structure.
Because of this, complete removal of the buccal fat pad is rarely recommended anymore. Instead, partial and highly tailored reductions are preferred. To see how conservative treatments maintain balance, you can Check out the results of some patients.
Who Are the Best Candidates?
The reduction of the buccal fat pad is not suitable for everyone. The best candidates for this procedure are typically:
Individuals with genetically rounder or “baby” faces.
Patients with true excess volume in the mid and lower thirds of the face.
Younger individuals (usually in their 20s or 30s) with increased fat volume in this area.
In these specific cases, a conservative reduction of the buccal fat pad can create a more balanced, refined, and beautifully contoured face.
Who Should Avoid Bichectomy?
Certain profiles should strictly avoid modifying the buccal fat pad due to a much higher risk of unfavorable outcomes:
Very thin individuals with low body fat percentages.
Patients with long, narrow, or naturally angular faces.
Individuals with existing facial volume loss or hollow cheeks.
Patients over 40–45 years old, as natural fat atrophy is already underway.
In these situations, removing the buccal fat pad may worsen the facial appearance rather than improve it, resulting in a skeletal look.
How Is the Procedure Performed?
The surgical alteration of the buccal fat pad is performed through a small incision inside the mouth, usually measuring less than two centimeters. This intraoral approach means there are no visible external scars on the skin.
Surgical Precautions
Because of the surrounding anatomy, the procedure must be done with extreme care. The buccal fat pad lies close to the buccal branch of the facial nerve and the parotid gland duct, which carries saliva into the mouth.
Important Note: A surgeon must ensure that the fat removal is strictly partial. Maintaining a protective layer of tissue ensures a natural, safe, and long-lasting result.
The recovery is generally quick, similar to a dental extraction, but following post-operative care is vital to prevent infection or swelling.
Long-Term Alternatives to Fat Removal
For patients who desire a slimmer face but are not ideal candidates for buccal fat pad removal, alternative treatments exist. These alternatives do not compromise the deep structural fat of the face.
Non-Surgical Slimming Options
Masseter Botox: Injecting botulinum toxin into the jaw muscles reduces their size, slimming the lower face without removing fat.
Dermal Fillers: Adding volume to the cheekbones can create an optical illusion, making the lower face appear slimmer and more lifted.
Ultrasound Therapy: Micro-focused ultrasound can tighten the skin and superficial fat layers, refining the jawline safely.
Seeking Professional Guidance
Before deciding to alter your buccal fat pad, an in-depth clinical consultation is mandatory. A board-certified plastic surgeon will evaluate your bone structure, skin thickness, and familial aging patterns.
For those looking for premium, individualized care, the Belvivere Clinic provides advanced facial analysis to ensure that any aesthetic intervention respects your natural anatomy and preserves your future beauty.
Conclusion
The buccal fat pad is a fundamental facial structure with important biological and mechanical functions that go far beyond aesthetics. While its reduction can provide structural benefits in well-selected cases, it should not be viewed as a simple, risk-free trend.
An individual evaluation is essential to avoid artificial results or premature aging. Today, the medical consensus is clear: less is more. Preserving the buccal fat pad or approaching its reduction with extreme caution is often the best way to maintain true facial harmony and long-term beauty.
