Preventing bleeding after a facelift (hematoma)

What it is

A facelift lifts the skin off the tissue beneath it, which leaves a space where blood can pool. A hematoma that is not drained can cause prolonged swelling or loss of the overlying skin (PMID 11513508). Most appear early: in one large series every hematoma that needed surgery showed within 48 hours, most of them within 15 hours (PMID 8171138).

How often it happens today: in a US registry, about 1 in 100 facelift patients had a hematoma that needed an emergency visit, a hospital stay or a return to surgery (PMID 26578747). Across deep-plane facelift studies, about 3 in 100 had any hematoma and about 1 in 100 had a major one (PMID 41203255).

Where it came from

• Blood pressure, 1976 onward. High blood pressure after surgery was identified as a key cause of hematoma in 1976 (PMID 16327611). At one hospital, hematoma needing surgery under general anesthesia fell from 3.26% in 1973 to 1.11% in 1994 after the team stopped letting blood pressure drop during the operation (PMID 8171138). In men, a strict blood pressure regimen cut it from 8.7% to 3.97% (PMID 16327611).
• Risk factors, 2001. A review of consecutive facelifts named the independent risks: tightening the neck muscle at the front of the neck, high systolic pressure, male sex, aspirin or anti-inflammatory drugs and smoking (PMID 11513508).
• Adrenaline and drains, 2004 to 2007. One surgeon found fewer hematomas needing surgery after he removed adrenaline from the numbing fluid (PMID 14707663). A randomized split-face trial in 2007 then showed that drains did not prevent hematoma, though they reduced bruising (PMID 17572574).
• Medicines before waking, 2010. Patients given pain, blood pressure, anti-nausea and calming medicines routinely before the breathing tube came out had no hematomas, against 7% in patients given them only on request (PMID 20333520).
• The net, 2014. Auersvald and Auersvald borrowed the quilting stitch used in tummy tucks and ran it through the skin and the SMAS-platysma to close the space under the flap (PMID 23949130).
• Trials and pooled data, 2021 to 2026. Tranexamic acid trials (PMID 32173730), the first randomized trial of the net (PMID 40131398) and several meta-analyses (PMID 41203255, PMID 42154899).

Who is at higher risk

• Men. Most series found higher rates in men; in a US registry male sex carried nearly four times the risk (PMID 26578747, PMID 25811571). The newest matched comparison, with standard prevention protocols, found no hematoma in men and no significant difference from women (PMID 42154486).
• High blood pressure. Systolic pressure above 160 before surgery was an independent risk (PMID 24912427), and pressure that swings widely during surgery or runs high right after it predicted hematoma (PMID 39163270).
• Aspirin, anti-inflammatory drugs and smoking (PMID 11513508).
• Neck muscle tightening at the front of the neck (PMID 11513508).

How surgeons prevent it

Blood pressure, pain and nausea

This is the measure with the most consistent support. A review of the evidence found that preventing pain, nausea and high blood pressure, keeping systolic pressure below 140, using fibrin glue and using local rather than general anesthesia lowered hematoma rates; drains, compression dressings and steroids did not (PMID 37540899). One surgeon's protocol, built on a clonidine skin patch and a systolic target of 140 or below, had a hematoma rate of 0.9%, and most patients who bled had high pressure in the recovery room (PMID 25811571). The same practice used calming drugs before surgery, anti-nausea drugs and a smooth wake-up (PMID 25415274). The evidence for clonidine itself comes mostly from case series (PMID 42434376).

Tranexamic acid (TXA)

TXA slows the breakdown of blood clots and is given by vein or mixed into the numbing fluid (PMID 40040948). Its clearest effect is on bruising: less bruising in a randomized trial of TXA by vein (PMID 32173730) and on the TXA side in a split-face study (PMID 39574336). Its effect on hematoma is mixed: one meta-analysis found fewer minor hematomas and less drain fluid, with no significant change in major hematoma (PMID 39141514); another, of TXA in the numbing fluid, found fewer hematomas overall (PMID 42689241). Wound-healing problems were reported after local TXA in 2023 (PMID 37265094), and a larger matched comparison found no increase at a dilute dose (PMID 40611665). TXA by vein and in the numbing fluid gave similar blood loss in a randomized trial (PMID 40040948).

Drains and tissue glue

Drains do not prevent hematoma, and they reduce bruising (PMID 17572574). Tissue glue (fibrin sealant) lowered hematoma and drain fluid in a pooled analysis of randomized trials (PMID 36260353), while an earlier single-surgeon series saw no difference with glue (PMID 14707663).

The hemostatic net

The net is a running nylon stitch passed in and out through the skin and the SMAS-platysma over the whole lifted area, holding the skin against the tissue beneath so blood has no space to collect (PMID 23949130). An internal version places the stitches under the skin (PMID 41181304, PMID 40498628).

What the evidence shows:

• Low rates with the net. Auersvald and Auersvald saw no hematoma in the first three days with the net, against 14.2% in their earlier patients (PMID 23949130). A second surgeon reported 0.6% with the net against 3.9% in his patients from 1999 to 2004 (PMID 37040449). Pooled data put hematoma with the net under 1% (PMID 41936137, PMID 42154899).
• Weak comparisons. Those comparisons use the surgeons' own earlier patients as controls (PMID 37040449). The only randomized trial found the net no better than drains for hematoma, seroma or swelling (PMID 40131398). A 2026 meta-analysis found the evidence that the net beats standard surgery to be of very low certainty (PMID 42154899).
• No clear winner. In pooled deep-plane data, major hematoma was about 1.2% with the net, 1.3% with tissue glue and 1.5% with TXA, with none clearly better (PMID 41203255). A review of quilting stitches in general found far fewer hematomas, from small studies, and advised caution until more work confirms safety (PMID 31784752). A third meta-analysis, outside PubMed, also found lower odds of hematoma with the net (Caimi 2025, Aesthet Surg J Open Forum).
• Skin blood flow. Dye imaging in patients, cadaver angiography and an animal flap study found no loss of skin blood supply from the net (PMID 36636947, PMID 37675581, PMID 39834174).
• Needle depth in the neck. CT measurements of the carotid artery led one group to advise a smaller needle for the net in the lower neck (PMID 41992563).

The surgical net and mesh

O'Daniel and Kachare renamed the technique the surgical net and describe its use to hold skin in a new position, beyond preventing hematoma (PMID 38806160). The gliding brow lift frees the forehead skin through small incisions and holds the brow with the net (PMID 31511923); the tail of the brow stayed about 3 mm higher at one year (PMID 39487802, PMID 41217905). The same idea is used around the eyes (PMID 41062668), for a sagging chin (PMID 40064646) and in breast surgery (PMID 35294963).

The net is a stitch pattern, and implanted mesh is a different thing. Mesh slings left in the neck appear in one small series, in which one mesh caused stiffness and was replaced (PMID 29794700); absorbable mesh has been tested only for strength in cadaver tissue (PMID 24676588).

Risks and how surgeons lower them

• Stitch marks from the net. Red marks appear in about 1 in 8 patients and fade within 2 to 3 months, with no lasting pigment in pooled data (PMID 41936137). In Thai patients, 9 in 10 sets of marks faded within a month and none left lasting dark pigment (PMID 39623234). For darker skin, some surgeons place the net under the skin to avoid marks (PMID 41181304).
• Local TXA and healing. Reported wound problems (PMID 37265094) were not seen at a dilute dose in a matched comparison (PMID 40611665).
• Drains do not prevent hematoma, so a drain is no substitute for blood pressure control (PMID 17572574, PMID 37540899).

Recovery

• The first night matters most: hematomas needing surgery appeared within 48 hours, most within 15 hours (PMID 8171138).
• High blood pressure in the recovery room was common among patients who bled (PMID 25811571), and medicines for pain, nausea and agitation given routinely, before they are asked for, prevented hematoma in one comparison (PMID 20333520).
• Drains, when used, came out at 1 to 2 days in a randomized trial (PMID 40040948).
• TXA and drains both reduce bruising (PMID 39574336, PMID 17572574).

Questions to ask a surgeon

• How will my blood pressure be kept down during surgery, as I wake up and through the first night? (PMID 25811571)
• Will I be given medicine for pain, nausea and agitation before I wake, or only when I ask? (PMID 20333520)
• Which medicines and supplements must I stop before surgery, and when? (PMID 11513508)
• Do you use tranexamic acid, tissue glue, drains or a net, and what is your own hematoma rate? (PMID 41203255)
• If you use a net, how long will the marks last on my skin? (PMID 39623234)
• Whom do I call if one side of my face or neck swells the first night? (PMID 8171138)

• Hemostatic net, Auersvald net, surgical net: a running stitch through the skin and SMAS-platysma that closes the space under the flap (PMID 23949130, PMID 38806160).
• Quilting stitch: a stitch that tacks the flap to the tissue beneath, placed inside or through the skin (PMID 31784752).
• Tranexamic acid (TXA): a drug that slows the breakdown of blood clots (PMID 39141514).
• Clonidine: a blood pressure drug used to hold pressure down after facelift (PMID 42434376).
• Tissue glue (fibrin sealant): a clotting protein applied to the raw surface under the flap (PMID 36260353, PMID 20333520).
• Dead space: the space under a lifted flap where fluid or blood can collect (PMID 42154899).
