Glossary
A Facial Rejuvenation Vocabulary, Defined
Eighteen terms — from cannula to twilight sedation — read across the surgical and the recovery registers a Seoul consult tends to move between.
One arrives at the facial rejuvenation conversation expecting an anatomical vocabulary, and finds instead two registers braided together — the surgical, which describes what is moved and how, and the recovery-and-assessment, which describes what the face does afterward and how it is read along the way. The Seoul corridor moves between the two without much ceremony, and a careful reader benefits from holding both. What follows is an alphabetised glossary of eighteen terms a patient is likely to meet across the consult and the convalescence, defined factually rather than persuasively — reference vocabulary, not advertising copy.
C
The C-terms sit at the instrument-and-garment end of the conversation — the blunt delivery tool and the post-operative pressure register.
Cannula
A blunt-tipped, hollow surgical tube — distinct from a sharp needle — passed beneath the skin to deliver tumescent fluid, to harvest or place fat, or to release fibrous attachments during facial procedures. The blunt tip is the defining feature; it is designed to glide between tissue planes rather than to cut them, which the surgical register associates with a lower incidence of vascular and nerve disruption than a comparable sharp instrument. The gauge and length are calibrated to the region. See also: tumescent anaesthesia, submental.
Compression garment
An elasticated post-operative wrap or facial band applied to the treated region to maintain even pressure during the early recovery window. The compression register serves several stated purposes — limiting the accumulation of fluid, supporting the redraped skin envelope against the underlying structure, and moderating swelling. The wear schedule is protocol-specific, typically heaviest in the first days and tapering thereafter. A patient should expect the garment instructions to be articulated as part of the recovery plan rather than as an afterthought. See also: edema, lymphatic drainage, skin envelope.
D
The D-term anchors the fluid-management register of the immediate post-operative window.
Drain
A thin, flexible tube placed beneath the skin at the close of certain facial procedures to evacuate blood and serous fluid that would otherwise collect in the surgical space. The drain register is selective rather than universal; some protocols use closed-suction drains for a day or two, others rely on compression and quilting sutures instead. The presence or absence of a drain is a protocol choice the consult will articulate, not a marker of complexity in itself. See also: compression garment, edema, ecchymosis.
E
The E-terms organise the two phenomena a recovering patient reads most directly in the mirror — the discoloration and the swelling.
Ecchymosis
The clinical term for bruising — the discoloration produced when small blood vessels leak beneath the skin and the pooled blood is gradually resorbed, passing through the familiar succession of purple, green, and yellow before clearing. Ecchymosis is an expected feature of the early facial-surgery recovery rather than a complication in most cases; its extent and duration vary with the procedure, the individual, and the use of compression. The consult will typically articulate an expected timeline. See also: edema, drain, lymphatic drainage.
Edema
The clinical term for swelling — the accumulation of fluid in the soft tissue that follows surgical handling and is part of the normal inflammatory recovery arc. Facial edema is generally most pronounced in the first days, settles substantially over the following weeks, and resolves its subtle residue over a longer tail of months in some regions. The recovery register reads edema as expected and self-limiting in most cases, with compression and drainage protocols positioned to moderate rather than abolish it. See also: ecchymosis, lymphatic drainage, compression garment.
F
The F-term sits at the lower-eyelid assessment register that the consult reads carefully against the tear-trough conversation.
Festoon
A fold or pouch of lax skin and soft tissue on the upper cheek or lower eyelid — sometimes called a malar mound or malar bag — that may hold fluid and is distinct from the tear-trough hollow it can sit beside. Festoons are an assessment register in their own right; they respond inconsistently to the techniques used for under-eye hollowing, and the consult will typically articulate the festoon as a separate consideration with its own management discussion. See also: tear trough, midface, edema.
G
The G-term anchors the deepest tier of the anaesthesia register.
General anaesthesia
A medically induced state of controlled unconsciousness, maintained and monitored by an anaesthesia provider, in which the patient has no awareness or sensation throughout the procedure. General anaesthesia sits at one end of the anaesthesia spectrum used for facial surgery, with twilight sedation and local-tumescent techniques occupying the lighter end. The choice is calibrated to the procedure's extent, the patient's medical register, and the surgeon's protocol; the consult will articulate which register applies and why. See also: twilight (IV) sedation, tumescent anaesthesia.
H
The H-term sits at the incision-planning register that governs where surgical access is taken and how it is concealed.
Hairline (temporal) incision
An incision placed along or within the temporal hairline, used in certain lifting approaches to access the upper face while concealing the scar within hair-bearing scalp. The temporal-hairline register involves a planning trade-off the consult will articulate — the concealment it offers against the way it can shift or elevate the hairline if tension is not managed carefully. The alternative pretrichial placement, sitting just in front of the hairline, is a different register with its own considerations. See also: scar maturation, midface, skin envelope.
L
The L-terms span the regional anatomy of the jaw-and-jowl zone and the manual-therapy register of recovery.
Lower face
The regional zone running from the corners of the mouth down to the jawline and including the jowl and marionette regions — one of the three horizontal divisions, alongside the midface and the upper face, that organise the rejuvenation assessment. The lower-face register is where laxity tends to read as jowling and where the jaw contour softens with age; the consult will typically assess it in relation to the neck and midface rather than in isolation. See also: midface, submental, ptosis.
Lymphatic drainage
In the recovery register, a gentle manual-massage technique applied to the post-operative face to encourage the lymphatic system to clear accumulated fluid and reduce edema. Lymphatic drainage is positioned as a supportive adjunct rather than a primary therapy; protocols vary in their timing and emphasis, and it is typically introduced once the early acute window has passed. The technique is distinct from the deep manipulation that the recovering surgical face generally avoids. See also: edema, ecchymosis, compression garment.
M
The M-term anchors the central horizontal zone of the facial assessment.
Midface
The central horizontal zone of the face — running roughly from the lower eyelid and cheekbone region down toward the nasolabial fold — and one of the three divisions that organise the rejuvenation conversation. The midface register is read for descent of the cheek soft tissue, flattening of the cheek projection, and deepening of the fold; the consult assesses it in relation to the tear trough above and the lower face below. The volume-and-position reading of the midface is a recurring assessment theme. See also: lower face, tear trough, ptosis.
P
The P-term anchors the descent register that underlies much of the rejuvenation assessment.
Ptosis
The clinical term for drooping or descent of a structure from its original position — most often used of the eyelid, the brow, or the descended soft tissue of the cheek and jaw. Ptosis is an assessment register rather than a procedure; the rejuvenation conversation reads where and how much descent has occurred and distinguishes true positional descent from volume loss and from skin laxity, since the three are addressed differently. The consult will typically articulate which register predominates. See also: facial laxity, midface, skin envelope.
S
The S-terms span the laxity-and-envelope assessment register, the scar-healing arc, the lower-jaw anatomy, and the suture-management milestone of recovery.
Scar maturation
The extended healing arc through which a surgical scar progresses — typically firmer, raised, and more visible in the early months before gradually softening, flattening, and fading toward its settled appearance over a year or more. Scar maturation is a recovery register that the consult articulates as a timeline rather than an event; the final read of any incision is deferred until the scar has matured. Sun protection and the relevant scar-care protocols are positioned within this window. See also: hairline (temporal) incision, suture removal, skin envelope.
Skin envelope
The skin layer considered as a single draped covering over the underlying facial structure — the term the surgical register uses when discussing how skin is redraped, where excess is trimmed, and how tension is distributed after the deeper layers have been repositioned. Reading the skin envelope separately from the structure beneath is central to the rejuvenation assessment, since laxity of the envelope and descent of the structure are distinct registers that are addressed differently. See also: facial laxity, ptosis, scar maturation.
Submental
The anatomical region beneath the chin — the term used of the soft tissue, fat, and skin under the jaw that organises much of the neck-and-jawline conversation. The submental register is where a small concealed incision is sometimes placed for access, where fullness reads as a softened jaw-neck angle, and where the lower-face and neck assessments meet. The consult will typically read the submental zone in relation to the jawline contour above and the neck below. See also: lower face, cannula, neck.
Suture removal
The recovery milestone at which non-dissolving stitches are taken out, generally within the first week or two depending on the region and the surgeon's protocol. Suture removal is a recovery register marker rather than a sign of completed healing; the deeper tissues continue to consolidate and the scar continues to mature well beyond it. Some protocols use dissolving sutures that require no removal, in which case the milestone is framed differently. See also: scar maturation, drain, ecchymosis.
T
The T-terms span the under-eye assessment register, the lighter sedation tier, and the local-anaesthetic infiltration technique.
Tear trough
The hollow or groove running diagonally from the inner corner of the eye along the junction of the lower eyelid and the cheek — an assessment register read for depth, shadowing, and its relationship to the midface above and the festoon beside it. The tear-trough conversation distinguishes a true hollow from the apparent darkness produced by overlying skin and from the fullness of an adjacent bag, since each is addressed differently. The consult will typically read the trough in context rather than in isolation. See also: festoon, midface, edema.
Tumescent anaesthesia
A local-anaesthesia technique in which a large volume of dilute anaesthetic-and-adrenaline solution is infiltrated into the surgical field, swelling the tissue, numbing the region, and constricting small vessels to limit bleeding. The tumescent register is used across a range of facial procedures, sometimes alone and sometimes alongside twilight sedation; the cannula is its usual delivery instrument. The consult will articulate how the tumescent technique fits the chosen anaesthesia plan. See also: cannula, twilight (IV) sedation, general anaesthesia.
Twilight (IV) sedation
An intravenously administered sedation register, lighter than general anaesthesia, in which the patient is deeply relaxed and drowsy — often with little or no recollection of the procedure — while retaining their own breathing and protective reflexes under monitoring. Twilight sedation occupies the middle of the anaesthesia spectrum, between local-tumescent techniques and full general anaesthesia, and is frequently paired with tumescent infiltration. The consult will articulate which register the procedure calls for. See also: general anaesthesia, tumescent anaesthesia.
Frequently asked questions
Why does this glossary mix surgical terms with recovery terms?
Because the consult conversation does. A patient assessing facial rejuvenation moves between the surgical register — what is repositioned, where the incisions sit, which anaesthesia tier applies — and the recovery register, which describes what the face does afterward: the edema, the ecchymosis, the suture-removal milestone, the long arc of scar maturation. Holding both vocabularies is more useful to a careful reader than holding either alone.
What is the difference between ptosis, laxity, and volume loss?
They are three distinct registers that the assessment reads separately. Ptosis is the descent of a structure from its original position; laxity is the looseness of the skin envelope; volume loss is the depletion of underlying soft-tissue fullness. The same aged appearance can arise from any one of them or from a combination, and because each is addressed differently, the consult typically articulates which register predominates rather than treating them as one phenomenon.
How are edema and ecchymosis read during recovery?
Both are expected features of the early recovery rather than complications in most cases. Edema is swelling — fluid accumulating in the soft tissue — generally most pronounced in the first days and settling over subsequent weeks. Ecchymosis is bruising, passing through the familiar succession of colours before clearing. The recovery register positions compression, drainage, and lymphatic-drainage protocols to moderate rather than abolish them, and the consult typically articulates an expected timeline.
What do the three anaesthesia registers mean — local, twilight, and general?
They describe a spectrum. Tumescent local anaesthesia numbs the surgical field while the patient is awake; twilight, or IV, sedation adds a deep relaxation in which the patient is drowsy and often retains little recollection while breathing independently; general anaesthesia is controlled unconsciousness maintained by an anaesthesia provider. The choice is calibrated to the procedure's extent and the patient's medical register, and the consult articulates which applies and why.
What does scar maturation involve, and why does it take so long?
Scar maturation is the extended arc through which a surgical scar progresses — typically firmer, raised, and more visible in the early months before gradually softening, flattening, and fading toward its settled appearance over a year or more. Because the read of any incision keeps changing through this window, the final assessment is deferred until the scar has matured, and sun protection and scar-care protocols are positioned within that timeline.
How do the facial zones — midface, lower face, submental — organise an assessment?
They divide the face into regions the consult reads in relation to one another rather than in isolation. The midface is the central zone, read for cheek descent and fold deepening; the lower face runs to the jawline and is where laxity reads as jowling; the submental zone beneath the chin organises the jaw-and-neck conversation. The tear trough sits above the midface. An assessment generally reads these zones together because change in one affects how its neighbours read.
