Deep plane vs. SMAS facelift: what is the difference, and which is better?
If you have been researching facelifts, you have seen the term “deep plane” everywhere. Here is how it differs from a SMAS facelift, and what the published studies show about results and safety.
Key points
- Both techniques lift the deeper support layer of the face (the SMAS), not just the skin. They differ in how that layer is handled.
- In head-to-head studies, including a randomized split-face trial and a study in identical twins, neither technique was clearly better for every patient.
- Deep plane lifts needed fewer touch-up procedures in one large series and had slightly higher patient satisfaction in pooled data.
- Permanent facial nerve injury is rare with both: about 0.05% in pooled data from more than 15,000 patients.
- The right technique depends on your anatomy and on your surgeon's training and experience with it.
What is the SMAS?
Under the skin and fat of the cheeks lies a firm sheet of connective tissue that continues into the platysma muscle of the neck. Surgeons call it the SMAS, short for superficial musculoaponeurotic system. With age, this layer and the fat it carries slide downward. That descent is what you see as jowls, deeper folds beside the mouth and a softer jawline.
The first facelifts tightened only the skin. Skin stretches, so a skin-only lift tends to look tight and relax early. Modern facelifts reposition the SMAS and let the skin redrape over it without tension. Both techniques in this article do exactly that.
How a SMAS facelift works
In a SMAS facelift, the skin is lifted off the SMAS first, and the two layers are handled separately. The surgeon then tightens the SMAS in one of three ways:
- Plication: the SMAS is folded on itself and stitched, without cutting it.
- SMASectomy (imbrication): a strip of SMAS is removed and the edges are sewn together.
- SMAS flap: the SMAS is lifted as its own layer and anchored higher.
The skin is then laid back down and the excess is trimmed.
How a deep plane facelift works
The deep plane facelift was described by Dr. Sam Hamra in 19901. Instead of separating skin from SMAS across the cheek, the surgeon works underneath the SMAS and releases the attachments that tether it to the deeper face. Skin, cheek fat and the SMAS-platysma layer then move together as one thick flap.
Hamra designed the operation to improve the folds between the nose and the mouth, which earlier facelifts changed very little1. In a cadaver study, a deep plane release also let the neck muscle move several times farther than SMAS plication did2.
Do the results differ? What the studies show
Several studies have compared the techniques directly, and most found less difference than you might expect:
- A randomized split-face study of 21 patients performed a limited or conventional SMAS lift on one side of the face and an extended SMAS or composite lift (a deep plane variant) on the other. Three independent surgeons could not detect a difference between the two sides in photographs taken 6 and 12 months later3.
- A masked comparison of 40 patients found that deep plane lifts did not score better than SMAS plication in patients younger than 70. In patients aged 70 to 80, deep plane scored slightly higher4.
- A study of eight pairs of identical twins, operated on with four different techniques, found that no single technique produced a superior result when it was matched to the right patient5.
- A 2026 randomized trial assigned 30 women to deep plane, high SMAS or plication facelifts. All three made patients look younger to 200 independent raters, with no statistical difference between the techniques6.
Other data favor the deep plane. In one surgeon's series of 634 facelifts, a later “tuck-up” procedure was needed after 11.4% of SMAS lifts and only 3.3% of deep plane lifts7. A 2025 meta-analysis of 21 studies and 2,896 patients found patient satisfaction of 94.4% after deep plane and 87.8% after SMAS facelifts8. Both numbers are high.
A systematic review in Plastic and Reconstructive Surgery concluded that high-quality comparative data were lacking and called for better trials9. More than a decade later, recent reviews still ask for longer follow-up.
Is one safer than the other?
The main concern with a deeper dissection is the facial nerve, which runs beneath the SMAS and moves the muscles of expression. The published data are reassuring for both approaches:
- A meta-analysis of 183 studies found that the risk of permanent nerve injury did not differ among facelift techniques. Temporary weakness was most frequent with high lateral SMAS (1.85%) and composite lifts (1.52%). Major hematoma, which is bleeding under the skin, was more frequent with deep plane (1.22%) and SMAS imbrication (1.92%) than with plication10.
- Pooled data from 15,404 facelift patients put motor nerve injury at 0.66% overall and permanent motor nerve injury at about 0.05%11.
- A 2026 meta-analysis limited to deep plane facelifts (45 studies, 10,784 patients) reported temporary facial nerve injury in 1.2%, hematoma in 1.8% and no permanent facial nerve injuries12.
- In an academic-center review of 229 facelifts, complication rates were not statistically different between lifts performed under the SMAS and skin-level lifts with or without plication13.
One 2025 meta-analysis did report a higher overall complication rate after deep plane (17.2%) than after SMAS facelifts (10.3%)8. Studies define “complication” differently, which makes these totals hard to compare.

Deep plane vs. SMAS at a glance
| SMAS facelift | Deep plane facelift | |
|---|---|---|
| How it lifts | Skin and SMAS are separated. The SMAS is tightened on its own. | Skin, fat and SMAS are released and lifted together as one unit. |
| What studies suggest | Scored as well or better in patients under 70 in one masked comparison4. | Designed for the folds beside the mouth1. Fewer touch-ups in one large series7. |
| Patient satisfaction (pooled) | 87.8%8 | 94.4%8 |
| Temporary nerve weakness | Under 2% in pooled data10 | About 1.2% in pooled data12 |
| Permanent nerve injury | Rare: about 0.05% across techniques11 | Rare: about 0.05% across techniques11 |
Which facelift is right for you?
The name of the technique matters less than whether it fits your face. These are the things I look at in a consultation:
- Where aging shows most: the jowls and jawline, the folds beside the mouth, the cheeks or the neck.
- The thickness and quality of your skin and the tissue under it.
- Whether this is your first facelift or a revision.
- Your health, your medications and the recovery time you can plan for.
The research supports fitting the operation to the patient. As the twin study concluded, there is no facelift technique suitable for every patient5. A surgeon's training and experience with the technique they recommend counts for more than its label.
Questions worth asking any surgeon you consult:
- Which technique do you recommend for my face, and why?
- How often do you perform it, and may I see before and after photos of patients like me?
- What are the risks for me specifically?
- Where is the surgery performed, and who provides the anesthesia?

Frequently asked questions
Is a deep plane facelift better than a SMAS facelift?
Not for everyone. Randomized and comparative studies, including one in identical twins, have not shown one technique to be clearly better across all patients. Deep plane lifts showed slightly higher patient satisfaction and fewer touch-up procedures in some studies. The best choice depends on your anatomy and your surgeon's experience.
Does a deep plane facelift last longer?
It may, but this has not been proven. One large series found fewer touch-up procedures after deep plane lifts (3.3% versus 11.4%). A randomized split-face study saw no difference at one year, and recent reviews still call for long-term comparisons.
Is a deep plane facelift more dangerous for the facial nerve?
Permanent facial nerve injury is rare with every modern technique: about 0.05% in pooled data from more than 15,000 patients, and a large meta-analysis found no difference between techniques. Temporary weakness, which recovers, occurs in roughly 1 to 2 percent.
How do I know which facelift technique I need?
You don't have to decide that yourself. At your consultation I examine your face and neck, listen to what bothers you, and recommend the approach that fits your anatomy and goals. I'll explain why, and what the alternatives are.
