You have probably spent an evening with fifteen tabs open, comparing surgeons, and come away knowing less than when you started. One page tells you the deep plane facelift is the only technique that gives a natural result. The next tells you the SMAS lift is the gold standard and "deep plane" is a marketing word. A third offers a "ponytail lift" with barely any downtime. They cannot all be right, and none of them explain what is actually being cut and moved.
I am going to explain the anatomy, because once you understand the layers of your own face the marketing collapses on its own, and you will be able to read any surgeon's page and work out in about ninety seconds whether they are describing an operation or selling a name.
I should declare my position first. The deep plane facelift is the operation I perform most often and the one my practice is known for. That is exactly why I am going to show you the evidence that does not flatter it — including a pooled complication rate higher than for SMAS techniques. If I showed you only the flattering half, you would have no way to judge the rest of what I tell you.
What the SMAS is, and why every facelift argument comes back to it
Your cheek is built in layers, and they are remarkably consistent from person to person. From the outside in:
Skin.
Subcutaneous fat — the layer sitting between the skin and the next layer down. This matters, because a great deal of confused writing implies the fat sits under the SMAS. In the lateral cheek it does not.
The superficial musculoaponeurotic system, or SMAS — a continuous fibrous sheet described by Mitz and Peyronie in 1976 (Plastic and Reconstructive Surgery 1976;58(1):80–88). It runs the length of the head and neck: it becomes the platysma in the neck, the temporoparietal fascia above the cheekbone, the galea over the scalp. The muscles of facial expression are embedded in it.
The sub-SMAS plane — loose areolar tissue, deep fat, and glide planes that let your face move when you smile.
The deep fascia — the parotidomasseteric fascia over the chewing muscle, and deep temporal fascia above the arch. The facial nerve branches travel beneath this layer for most of their course, then pierce it to enter the expression muscles from underneath.
That last point is the entire safety argument of facelift surgery. If you stay above the deep fascia, you are above the nerve.
Ageing does not happen evenly across those layers. Skin thins, fat deflates in some compartments and slides in others, the SMAS loses tension and descends, and bone resorbs. A technique that addresses only one of those layers can fix only one of those problems — which is the honest reason "just pull the skin tighter" produces a face that looks pulled rather than younger.
What actually happens in a deep plane dissection
In a classical SMAS facelift, the surgeon raises the skin off the SMAS in the subcutaneous plane, then separately tightens the SMAS underneath — folding it (plication), removing a strip (SMASectomy), or overlapping it (imbrication). Two layers, two separate moves, two separate tensions.
In a deep plane facelift — described in its modern form by Hamra in 1990 (Plastic and Reconstructive Surgery 1990;86(1):53–61) — the dissection goes underneath the SMAS from the start. Skin and SMAS stay attached and are lifted together as a single composite flap, thicker, with its blood supply intact through the subcutaneous plexus because the skin was never stripped off its underlying fat.
Two consequences follow. Tension is carried by the SMAS layer rather than the skin, which allows the incisions to be closed without pull and is why properly executed deep plane scars tend to behave well. And because the flap is thicker and better perfused, the risk of skin edge death is lower: a review of short-term facelift complications by Sinclair and colleagues (Aesthetic Surgery Journal Open Forum 2021;3(1):ojab007) reports skin necrosis at roughly 3.6% with subcutaneous technique and under 1% with deep plane approaches.
That is a genuine advantage. It is not the whole ledger.
The zygomatic and masseteric cutaneous ligaments — and why releasing them is the risky part
Your face is tethered to your skeleton and deep fascia by retaining ligaments, and two of them decide almost everything about a mid-face lift.
The zygomatic retaining ligaments run from the cheekbone directly to the dermis, at the spot generations of surgeons have called McGregor's patch. They are why the cheek fat pad hangs where it does and why a deepening nasolabial fold resists being pulled sideways.
The masseteric cutaneous ligaments run vertically along the front edge of the chewing muscle, from deep fascia out to skin. They are the boundary jowl tissue falls over: when you see a jowl, you are largely seeing soft tissue that has descended and been caught by that line.
A deep plane facelift releases these ligaments under direct vision. That is the operation; everything else is closure. And it is precisely at the point of release that the facial nerve branches are closest — the zygomatic and buccal branches run just deep to the fascia in that territory, and the frontal branch crosses the zygomatic arch in a well-described but forgiving-of-nobody corridor. A surgeon releasing ligaments is working within a few millimetres of nerves that do not grow back well if divided.
This is why I do not accept the framing that deep plane is simply “better”. It is a more complete release performed in a more dangerous neighbourhood. Whether that trade is worth it depends on the face and on the surgeon’s hands, not on the name of the technique. I have trained in it specifically, and the anatomical work on the facial spaces and their ligamentous boundaries underlies most of what I have described.
Vertical versus lateral: why the vector matters more than the name
Faces do not age sideways. They age downwards, with volume loss. So the correction should be predominantly upwards. Pulling laterally produces the look everyone fears — the mouth drawn towards the ear, the flattened cheek, the wind-tunnel quality — because it tightens the skin envelope without lifting descended tissue back onto the cheekbone.
Because a deep plane flap has been released from its ligaments, it can be repositioned vertically without the skin fighting back. A plicated SMAS, still tethered by intact zygomatic ligaments, generally cannot be moved as far superiorly, so it is more often set with an oblique or lateral vector. That is the honest mechanical difference between the techniques. Not "natural versus unnatural" — direction of travel, and how much release was needed to achieve it.

Theatre times vary with the extent of the release and with what is combined; an estimate for your own operation is given at consultation.
What the evidence says about deep plane versus SMAS
In 2025, Khoury, Almubarak, Khan, Boldt, Villemure-Poliquin and Nichols published a systematic review and meta-analysis in Aesthetic Plastic Surgery (2025;49:5895–5903, doi:10.1007/s00266-025-05118-x) pooling 21 studies and 2,896 patients. Their conclusion is not the one my marketing would prefer: deep plane and SMAS facelifts "both provide robust and long-term outcomes with high patient satisfaction," and they could not declare either technique superior on longevity.
On safety, the numbers ran against the operation I perform most:
OutcomeDeep planeSMASPooled complication rate17.2%10.3% (95% CI 6.20–14.4)Pooled patient satisfaction94.4% (95% CI 84.8–99.7)87.8% (95% CI 84.3–91.3)
A higher complication rate for the deep plane technique, in the best synthesis currently available. Hold two things at once: these are pooled figures across many surgeons and many definitions of "complication", most of which were transient — and they are still the numbers. Any surgeon telling you deep plane is simply the safer operation is not reading the literature.
Where the mini lift is honest, and where it is not
A mini or short-scar lift is a real, legitimate operation: limited skin undermining, a purse-string or plication tightening of the SMAS, a scar confined largely to the front of the ear. In a woman in her late forties with early jowling, good skin quality and a neck that is genuinely fine, it can do exactly what she needs with a fraction of the recovery.
Where it becomes dishonest is when it is sold to someone whose actual problem is a heavy neck. A mini lift does not treat the neck — it cannot, because the dissection does not go there. If you have platysmal banding or submental fullness and you are offered a mini lift, you are being offered an operation that will not address the thing you dislike, and you will pay for it twice.
Is the "ponytail lift" a real operation?
No — not as a defined surgical procedure. There is no standard anatomical definition, no agreed plane, no agreed vector. It is a name for the effect people want: the temporarily lifted look you get when you pull your hair back tightly.
What surgeons perform under that banner varies enormously, usually some combination of temporal or endoscopic brow work with a short-scar or deep plane cheek lift, hidden in hair-bearing scalp. Some of those are excellent operations. The problem is that the label tells you nothing. If you are offered a ponytail lift, the only useful response is: which plane, which ligaments, which vector, and where exactly are the incisions?
What these cost, and what the price does not tell you
Our published prices are indicative in Australian dollars and confirmed at booking:
Mid/Lower Face Lift — A$7,000 / ฿159,000
Mid/Lower Face and Neck Lift — A$7,400 / ฿170,000
Lower Face and Neck Lift with neck muscle tightening — A$9,200 / ฿210,000
The above with under-chin correction — A$11,400 / ฿260,000
The above with VASER — A$14,400 / ฿330,000
Endoscopic Forehead Lift — A$7,400 / ฿170,000
Notice what that list is organised by: how much of the face and neck is addressed, not which plane I work in. Notice also what it excludes — flights, accommodation, extra days if you need them, and any revision. Medicare does not cover overseas medical treatment, Australia has no reciprocal health agreement with Thailand, Australian private health insurance generally does not cover procedures performed overseas and may not cover follow-up at home, and standard travel insurance generally excludes medical tourism. Price the whole thing, not the surgery.
When to seek care
Whichever technique you have, these are the signs that matter.
Emergency — go to a hospital emergency department immediately, wherever you are: rapid one-sided swelling of the face or neck, particularly in the first 24 to 48 hours; escalating pain with tightness or pressure; any difficulty breathing or swallowing; a sudden colour change in the skin over a swollen area. An expanding haematoma is the most common serious complication of a facelift and it is time-critical — do not wait to email your surgeon from another country. Around 90% occur within the first 24 hours (Sinclair et al., 2021), which is why I ask patients to stay near the hospital through that window.
Same-day review: fever above 38°C; redness spreading from an incision; discharge or an unpleasant smell; new inability to raise an eyebrow, close an eye fully, or move one side of the mouth; darkening or blistering of skin in front of or behind the ear; calf pain or swelling, chest pain or breathlessness at any point in the first six weeks, which needs assessment for venous thromboembolism regardless of how well your face is healing.
Routine review: patchy numbness of the cheek and ear, tingling or electric sensations as nerves recover, asymmetric swelling in the first weeks, firm lumps under the incision, and itching. Not pleasant, but ordinary.
How I actually choose in the consultation
I do not walk into a consultation intending to perform a particular technique. I look at four things: how much of your face has descended versus how much has deflated; the quality and thickness of your skin; the state of your neck, including whether the fullness sits above or below the platysma; and your medical risk, particularly blood pressure, smoking and anticoagulant use.
A patient with genuine ligamentous descent, a heavy mid-face and reasonable skin gets a deep plane release, because that is the problem it solves. A patient with mild jowling, thin skin and a clean neck gets a SMAS technique, because the pooled evidence says her satisfaction will be similar and her complication risk lower. A patient whose face has deflated rather than descended may need grafting more than lifting — lifting an empty face makes it look emptier.
