Deep plane facelift — anatomic basis for the results, case walkthrough [before/after]
I’m a plastic surgeon who specializes in deep plane facelifts. I want to use this case to walk through the actual anatomy driving the visible result.
The anatomic problem aging creates — specifically
Facial aging is not simply skin laxity. That’s a critical misconception that drives a lot of undertreated patients.
What’s actually happening is a composite process operating at multiple tissue depths simultaneously:
The retaining ligaments of the face — particularly the zygomatic cutaneous ligaments (McGregor’s patch), the masseteric cutaneous ligaments, and the mandibular ligaments — are fibrous condensations that tether the overlying soft tissue envelope to the underlying facial skeleton and deep fascia. With age, these ligaments attenuate. The soft tissue they were suspending — the malar fat pad, the buccal fat, the SOOF (suborbicularis oculi fat) — descends along predictable vectors.
The result is the constellation of findings we associate with facial aging: malar flattening, deepening of the nasolabial fold, jowl formation at the mandibular border as the descended cheek fat pad overrides the mandibular ligament, and loss of the cervicomental angle as the platysma weakens and subplatysmal fat accumulates.
This patient presented with all of it: prominent jowling effacing the mandibular line, midface descent with a deepened nasolabial fold, platysmal banding, and excess subplatysmal fat producing a blunted neck-chin angle. Her skin quality was good. The issue was structural.
Why the plane of dissection determines everything (almost)
A traditional SMASectomy or SMAS plication operates on top of or within the SMAS, leaving the retaining ligaments intact. The skin and SMAS are repositioned, but the tethering anatomy that caused the descent in the first place is never released. You’re working against fixed points. The vector of pull is therefore oblique and posterior — which is why superficial plane lifts can produce that telltale lateral sweep, and why tension on the skin closure is higher, predisposing to visible scars and earlobe distortion.
The deep plane dissection enters the sub-SMAS plane and carries the dissection anteromedially to directly release the zygomatic and masseteric cutaneous ligaments under direct visualization. Once those ligaments are released, the entire composite flap — skin, SMAS, and adherent facial soft tissue as a single anatomic unit — becomes mobile. It can be advanced superiorly and posteriorly along a more natural vector without skin tension, because the skin is not being asked to do the work of repositioning.
This is the mechanical distinction that matters: in a deep plane lift, the soft tissue is being repositioned to where it originated. In a superficial plane lift, the SMAS layer is being tightened and the skin is being pulled back to from where it has fallen. The clinical difference is naturalness of result, longevity, and the indirect improvement of the nasolabial fold — which improves not because it is excised or filled, but because the malar fat pad sitting above it has been restored to its native position.
What happened in this specific case
Frontal view: The jowling that had been overriding the mandibular border is resolved. The jawline is continuous and uninterrupted from the chin to the angle of the mandible. The nasolabial folds are softened — not eliminated, because that would look operated — through superior repositioning of the malar fat pad. The midface has a fuller, more convex contour because the descended soft tissue has been returned to the zygomatic eminence rather than sagging off of it.
Lateral and oblique views: The neck result is where the anatomy becomes particularly instructive. Preoperatively, she had both supraplatysmal and subplatysmal fat excess, along with visible platysmal diastasis — the separation of the paired platysmal muscles at the midline that produces vertical banding and a poorly defined cervicomental angle.
The neck was addressed through a separate submental incision. Direct lipectomy was performed in the subplatysmal plane to address the fat depot sitting behind the platysma. A corset platysmaplasty was then performed — the medial borders of the platysma were reapproximated in the midline with suture restoring the muscular sling that defines the anterior neck contour. Posteriorly the SMAS was anchored via the Mastoid Crevasse technique to elongate the jawline and give it depth.
The cervicomental angle in the postoperative lateral views reflects this combined approach: it is acute, well-defined, and anatomically appropriate rather than artificially sharp.
Incision and earlobe anatomy: One of the surgical details I pay close attention to is the relationship of the closure to the tragus and earlobe. Pixie ear deformity — inferior and anterior displacement of the earlobe — occurs when the skin flap is closed under excess tension, pulling the lobule out of its natural position. Because the deep plane composite flap is repositioned under no skin tension, the earlobe closure is tension-free and the lobule hangs at its native angle.
Longevity — the anatomic argument
Deep plane results are consistently reported to last longer than superficial plane results. The anatomic argument for why is straightforward: the retaining ligaments have been released and the soft tissue repositioned relative to the skeleton. The reattachment of the composite flap in its new position, combined with scar maturation at the new attachment points, creates durable fixation. The recurrence of descent requires the new adhesions to re-attenuate — a process that takes considerably longer than the progressive stretching of a SMAS tightening repair done under tension.
This is not to say deep plane facelifts are permanent. They are not. But the architecture of the repair is fundamentally more stable in my hands.
Appropriate candidacy — this doesn’t work for everyone
This patient was a good candidate: significant but not extreme soft tissue descent, good bone structure, non-smoker, realistic expectations, adequate skin quality. Deep plane surgery in patients with very thin skin, severe photodamage, or heavily fibrosed tissue from prior surgery requires significant modification of technique.
The operation is also longer and the recovery more involved than superficial alternatives in my experience. Swelling is greater because the dissection is deeper and more extensive. She was significantly edematous for the first two weeks, presentable socially by three to four weeks, and largely settled at 3-4 months — which is when these images were taken. Final result continues to refine for up to twelve months as residual deep edema resolves.
