Dr Scott J Turner | Specialist Plastic Surgeon (FRACS) | Sydney
Patients researching facelift surgery hit two terms repeatedly: SMAS and deep plane. The marketing language around both can be loud. The clinical substance is more nuanced. Both are modern structural facelift techniques. Both have a long track record. Both can deliver durable outcomes when matched to the right anatomy. Neither is universally better for every patient.
This article goes deep on the technique comparison specifically. What the SMAS layer actually is. What “deep plane” means anatomically. How the mechanism of each technique differs. How the decision gets made at consultation. What the published evidence shows about risk and durability. Where neck lift planning fits into the picture for Canberra patients.
For the full Canberra face and neck lift overview, including consultation at the Campbell clinic, neck lift planning, recovery, risks, and Sydney surgery logistics, start with the Face & Neck Lift Canberra page. This article focuses specifically on the difference between deep plane and SMAS facelift techniques. Dr Scott J Turner is a Specialist Plastic Surgeon (FRACS) consulting at the Campbell clinic in Canberra and at Sydney clinics in Bondi Junction and Manly.

Quick comparison: SMAS vs deep plane
Side-by-side:
| Feature | SMAS facelift | Deep plane facelift |
|---|---|---|
| Main layer addressed | SMAS layer beneath the skin | Deep plane beneath the SMAS, with retaining ligament release |
| Main mechanism | Tightens, folds, or repositions the SMAS layer | Releases facial retaining ligaments and repositions skin and SMAS as a composite flap |
| Common role | Mild to moderate lower-face descent in selected patients | More comprehensive facial descent, especially midface and jowl concerns |
| Neck involvement | May be combined with neck lift or platysmal work | May be combined with neck lift or platysmal work |
| Complexity | Structural facelift technique with an established track record | More technically demanding and anatomy-dependent |
| Decision point | Suitable when patient anatomy and goals match the technique | Suitable when ligament release and deeper repositioning are appropriate |
The right technique isn’t chosen from a menu. It’s based on facial anatomy, skin quality, neck involvement, degree of descent, previous surgery, and patient goals.
The anatomy: SMAS and the deep plane
Worth understanding what each layer actually is, before discussing what happens to it during surgery.
The SMAS (superficial musculoaponeurotic system) is a layer of fibrous tissue and muscle that sits beneath the skin and subcutaneous fat. It runs continuously across the face, connecting muscles of facial expression. It provides structural support and transmits movement from the underlying muscles to the overlying skin.
The deep plane sits beneath the SMAS. Below this layer are the facial retaining ligaments (zygomatic, masseteric, mandibular) and the deeper soft tissues that descend with age. The deep plane isn’t a single anatomical layer but rather the surgical space below the SMAS where dissection occurs in deep plane facelift technique.
The distinction matters because the two techniques work in different anatomical spaces. SMAS facelift addresses the SMAS layer. Deep plane facelift goes deeper, releases the retaining ligaments, and repositions the SMAS and overlying skin as a single composite flap.
SMAS facelift: mechanism and role
SMAS facelift addresses the SMAS layer through one of several variations: SMAS plication (folding the SMAS on itself), SMAS imbrication (overlapping and securing the SMAS), or SMAS flap elevation (raising and repositioning the SMAS).
The mechanism is structural. By repositioning the SMAS, the technique addresses the deeper support layer that has descended over time. Skin then redrapes over the new SMAS position rather than being tightened under tension. This is the key difference between modern SMAS technique and the historical skin-only facelift.
SMAS facelift has a long evidence base. The technique has been refined over decades. It’s appropriate for patients with lower-face and jawline ageing where SMAS-level repositioning addresses the clinical findings.
Deep plane facelift: mechanism and role
Deep plane facelift dissects below the SMAS. The key step is release of the facial retaining ligaments, which anchor the soft tissues of the cheek and midface to the underlying skeleton. By releasing these ligaments, the technique allows the SMAS and overlying skin to be repositioned as a single composite flap, without the skin and SMAS being moved independently.
The mechanism has a structural rationale for addressing midface descent specifically. Where the cheek soft tissues have descended significantly, ligament release may achieve repositioning that SMAS plication or imbrication alone cannot reach as comprehensively.
Deep plane facelift is more technically demanding because dissection occurs closer to important facial nerve branches and the retaining ligaments. Surgeon experience and patient selection matter.
Where neck lift planning fits in
Patients often compare deep plane and SMAS facelifts as if the face is assessed separately from the neck. In practice, jowling, jawline definition, platysmal bands, and loose neck skin are assessed together. A facelift technique addresses facial descent, but neck lift planning may still be required when the neck is a major concern.
This is independent of facelift technique choice. A deep plane facelift can be combined with neck lift planning. So can a SMAS facelift. The decision about whether to address the neck depends on clinical findings, not on the facelift technique selected.
For the full discussion of face and neck lift planning for ACT patients, see the Face & Neck Lift Canberra page.
Is deep plane facelift riskier than SMAS?
The honest answer: complication rates vary, and technique selection should account for risk profile alongside other factors.
A 2025 systematic review reported high satisfaction with both deep plane and SMAS facelifts, with deep plane satisfaction of 94.4% and SMAS satisfaction of 87.8%. Overall complication rates in the included studies were 17.2% for deep plane and 10.3% for SMAS. Both techniques produced satisfactory outcomes, but the risk profile differs.
A separate meta-analysis of SMAS facelifting techniques found statistically significant differences between techniques for temporary facial nerve injury, haematoma, seroma, necrosis, and infection. The conclusion: technique should be selected based on quality of results matched to anatomy, with the complication profile understood as part of the decision rather than the deciding factor in isolation.
Specific risks worth understanding regardless of technique:
- Haematoma: blood collection beneath the skin that may require return to theatre for drainage. The most common facelift complication requiring operative intervention.
- Nerve injury: facial nerve branches run within the surgical field. Temporary weakness is more common; permanent injury is rare but reported.
- Altered sensation: numbness or hypersensitivity around the operated area, usually temporary.
- Skin healing problems: more common in patients who smoke or vape. Nicotine impairs blood supply to the skin.
- Scarring: incisions are typically placed within the hairline and around the ear, but visibility depends on individual healing.
- Asymmetry: the two sides of the face may heal slightly differently even with symmetric surgical correction.
- Infection: uncommon with appropriate sterile technique and antibiotic protocol.
- Revision surgery: may be considered where the result doesn’t meet expectations or where ageing continues.
Deep plane dissection occurs closer to facial nerve branches and the retaining ligaments. That doesn’t make it inappropriate for the right patient, but it does mean the surgeon’s experience with the specific technique is part of the safety equation.
How long do results last?
Patients often ask which technique lasts longer. The structural rationale for deep plane facelift suggests it may have advantages for durability in some cases because it releases retaining ligaments and repositions soft tissue more comprehensively. Whether that translates to consistently longer-lasting results across all patients is less clear from the published evidence.
Longevity varies regardless of technique. The variables include anatomy, skin quality, sun exposure, smoking status, weight fluctuation, surgical technique, and ageing pattern.
Published reviews support both techniques as capable of robust long-term outcomes. The 2025 systematic review found high satisfaction with both deep plane and SMAS facelifts. Many patients think in terms of years rather than months when planning facelift surgery, but no facelift technique stops ageing. The expected duration of improvement is discussed individually at consultation rather than promised as a fixed figure.
Consultation pathway under AHPRA cosmetic surgery guidelines
The Medical Board and AHPRA cosmetic surgery guidelines that came into effect in July 2023 set the consultation pathway requirements.
Current requirements:
- GP or eligible specialist referral is required before the cosmetic surgery consultation
- At least two pre-operative consultations with the operating surgeon, with at least one in person
- Consent forms cannot be requested at the first consultation. Informed consent is finalised at the second
- Cooling-off period of at least seven days after the second consultation and informed consent before surgery can be booked or a deposit paid
- Psychological screening for body dysmorphic disorder and other relevant factors using a validated tool, with further independent assessment recommended where clinically indicated
Minimum total timeline from first consultation to surgery booking: 14 days. For preparation, see the Plastic Surgery Consultation Checklist.
For Canberra patients: technique selection at consultation
Technique selection happens at consultation, not before. The consultation isn’t a discussion about which technique you’d like. It’s an assessment where anatomy, skin quality, midface involvement, neck involvement, and goals are evaluated, and the appropriate technique gets recommended based on those findings.
For Canberra and ACT patients, consultations occur at the Campbell clinic. Surgery is performed at accredited private hospital facilities in Sydney. Follow-up is planned through the Campbell clinic where appropriate, with Sydney review arranged when needed based on procedure complexity, healing, and early recovery stage.

Frequently asked questions
Is deep plane facelift better than SMAS facelift?
Not for every patient. Deep plane facelift and SMAS facelift are both structural facelift techniques. Deep plane may be more appropriate for patients with more significant facial descent or midface involvement, while SMAS techniques may suit selected patients with milder lower-face concerns. Published evidence shows high satisfaction with both approaches. The right technique depends on anatomy, skin quality, neck involvement, previous surgery, and goals, not on a fixed preference for either technique.
Is deep plane facelift riskier than SMAS facelift?
Deep plane dissection is more technically demanding and occurs closer to important facial nerve branches. Published meta-analysis data show complication rates vary between SMAS and deeper-plane techniques, including differences in temporary nerve injury, haematoma, seroma, necrosis, and infection. Surgeon experience, patient selection, and technique-specific care matter more than the name of the procedure alone. Both techniques have a long track record in modern facelift surgery.
Does deep plane facelift include the neck?
Deep plane facelift addresses facial soft tissue, but neck involvement depends on individual anatomy. Where jowling, jawline definition, platysmal bands, and loose neck skin are also concerns, neck lift may be planned at the same procedure regardless of which facelift technique is selected. The face and neck are assessed together because they often age together. For the full discussion of face and neck planning, see the Face & Neck Lift Canberra page.
How long do deep plane and SMAS facelift results last?
No facelift technique stops ageing. Longevity varies by anatomy, skin quality, lifestyle, sun exposure, smoking status, weight fluctuation, and surgical plan. Published reviews show high satisfaction with both deep plane and SMAS facelifts, so consultation should focus on which technique best matches the patient rather than a guaranteed number of years. The expected duration of improvement is discussed individually at consultation, not promised as a fixed figure.
How do Canberra patients decide which technique is right?
Technique selection happens during consultation at the Campbell clinic, after assessment of facial anatomy, degree of descent, midface involvement, neck involvement, skin quality, health history, and goals. Surgery is performed in Sydney, with follow-up planned through the Campbell clinic where appropriate. The choice between deep plane and SMAS isn’t made from a menu; it’s determined by the clinical findings at consultation.
