Lower Blepharoplasty: Is Fat Removal Always Necessary? – All About Fat Preservation and Repositioning
Explore the nuances of lower blepharoplasty, comparing traditional fat removal with modern fat preservation and repositioning techniques. Learn about the benefits, drawbacks, and ideal candidates for each method, including insights from BC Mendelson's technique.
Under-eye fat, which protrudes to create the appearance of dark circles or makes one look tired and older. Should it simply be removed? Or should it be preserved?
Recently, in plastic surgery, methods of repositioning or preserving under-eye fat are gaining increasing attention, moving away from simple removal. Today, we will explore the supporting research, actual surgical methods, and suitable candidates for these techniques.
Under-eye Fat Removal vs. Fat Preservation: What's the Difference?
Category | Fat Removal | Fat Repositioning/Preservation |
Advantages | Quick results, simple surgery | Natural appearance, long-lasting results |
Disadvantages | Risk of hollowing, can make one look older | Higher surgical difficulty, requires precision |
Suitable Candidates | Significant fat and severe skin laxity | Younger patients with good skin elasticity |
Why is Fat Preservation Important?
As we age, the **fibrous tissue (orbital septum)** that supports the fat beneath the eyelids weakens, causing the fat to protrude forward.
Simply removing this fat may flatten the area temporarily, but over time, the under-eye area can become hollow or even appear more aged.
Fat preservation surgery involves moving this fat inward and reinforcing the supporting structures to create a natural and stable under-eye contour.
Dr. BC Mendelson's Fat Preservation Technique
Fat Preservation Technique of Lower-lid Blepharoplasty
(2001, Aesthetic Surgery Journal)
Key Concept: Repositioning and fixing fat inward without removing it.
Surgical Method:
Incise the under-eye skin to expose the fat layer
Reinforce the **capsulopalpebral fascia** to prevent fat from protruding again
After repositioning the fat, fix the fascia to the cheekbone to maintain a natural curve
What is Capsulopalpebral Fascia Repair?
A surgery that strengthens the under-eye fascia and orbital septum to prevent under-eye fat from protruding again.
When this fascia is strengthened, it can prevent the area from becoming puffy again while preserving the fat.
It also helps reduce side effects such as eyelid eversion (ectropion) after surgery.
Who is Suitable for Fat Preservation Surgery?
Relatively younger patients, typically under 50
Those with a relatively defined cheekbone structure
Those with prominent under-eye fat but not severe skin laxity
Those concerned about hollowing or desiring natural results
Conversely, if skin laxity is severe or cheekbones are not well-developed, it may be necessary to combine it with lifting procedures such as a facelift.
Recovery Period?
Similar recovery speed to general fat removal, but swelling and bruising vary individually
Final results settle naturally after 2-3 months
Conclusion Summary
✅ Repositioning/preservation of fat is more advantageous than removal for creating natural-looking eyes.
✅ BC Mendelson's technique is an anatomically based method proven for both safety and effectiveness.
✅ Precise diagnosis and the judgment of an experienced specialist are crucial.

Frequently Asked Questions
What is the biggest difference between fat removal and fat preservation surgery?
Fat removal is a method of simply eliminating bulging fat, while fat preservation surgery involves repositioning and fixing the fat inward without removing it, and reinforcing the supporting structures. Fat preservation surgery is advantageous for naturalness and long-term maintenance.
What problems can arise if under-eye fat is simply removed?
Simply removing under-eye fat can temporarily flatten the area, but over time, the under-eye area can become hollow or even appear more aged. This is because the fibrous tissue supporting the fat weakens.
Who is suitable for fat preservation surgery?
Fat preservation surgery is generally suitable for relatively younger patients, typically under 50, with a defined cheekbone structure and prominent under-eye fat but not severe skin laxity. It is also good for those who desire natural results.
What is Dr. BC Mendelson's fat preservation technique?
Dr. BC Mendelson's technique involves repositioning and fixing under-eye fat inward without removing it. It strengthens the capsulopalpebral fascia and fixes the fat to the cheekbone to maintain a natural under-eye contour.
How long is the recovery period after fat preservation surgery?
The recovery speed for fat preservation surgery is similar to general fat removal, and swelling and bruising vary individually. Final results usually settle naturally after 2-3 months post-surgery.
