What the research shows
How often and when. In deep plane facelifts reported up to 2026, about 1 patient in 40 had a hematoma of any size and about 1 in 100 had a major one that needed a return to the operating room (Azzi 2026). Bleeding that needs surgery appears early: every case in one long series showed within 48 hours, most within 15 hours (Rees 1994). Untreated, it can cause lasting swelling or skin loss (Grover 2001).
Who is at higher risk. High systolic blood pressure, male sex, aspirin or anti-inflammatory pills, smoking and tightening of the front neck muscle each raised the risk independently (Grover 2001). Men historically bled more often, about 4 in 100 against 1 to 3 in 100 women (Baker 2005); under a modern prevention protocol, matched men and women had the same rate (Vishwanath 2026). Patients given heparin injections to prevent clots bled about 1 time in 6, against about 1 in 100 without them (Durnig 2006). SSRI antidepressants did not raise the rate, and the authors found no reason to stop them (Harirchian 2012).
Blood pressure control. A strict blood pressure regimen cut hematomas needing surgery in men by about half (Baker 2005). A clonidine patch with a systolic target of 140 or lower kept hematoma under 1 in 100 (Ramanadham 2015), and holding systolic pressure below 120 after surgery dropped one surgeon's rate from about 1 in 27 to about 1 in 200 with no harm from the lower pressure (Bassiri-Tehrani 2023). Swings in pressure during surgery and high pressure right after it predicted bleeding (Abi-Rafeh 2024). These are single-practice series compared with earlier years; the clonidine evidence is mostly series and expert opinion (Mobasser 2026).
Tranexamic acid (TXA). TXA slows the breakdown of clots; it is given by vein or in the numbing fluid. Pooled studies show fewer small hematomas and less drainage, with no change in major hematomas or major complications (Alenazi 2024); local TXA was tied to fewer hematomas overall (Mokhtar 2026). In a split-face trial, the TXA side bruised less at one week (Klimczak 2025). A matched comparison found no increase in wound-healing problems at standard local doses (Darras 2025).
The hemostatic net. A running stitch through the skin and the layer beneath closes the space where blood pools. Its originator reported no early hematomas with the net (Auersvald 2014), and a second surgeon saw a sharp drop (Janssen 2023). Pooled results show hematoma is rare with it; about 1 patient in 8 gets red stitch marks, which fade fully within 2 to 3 months (Ribeiro 2026). In a randomized trial against drains, the two did equally well for hematoma, fluid and swelling (Ismail 2025).
Drains and glues. A drain on one side of the face did not change hematoma or swelling but reduced bruising (Jones 2007), and drains cut collections of clear fluid (Perkins 1997). Tissue glues (fibrin sealants) lowered drainage and hematoma in pooled randomized trials, a result at the edge of statistical certainty (Chien 2023).
Where surgeons disagree
- How much glue adds. An early pooled analysis found no clear benefit (Por 2009), and one surgeon's series found glue, drains and dressings made no difference (Jones 2004); the pooled randomized trials favor glue (Chien 2023).
- Adrenaline in the numbing fluid. Jones stopped using it and his hematomas fell (Jones 2004); other surgeons still inject it routinely (Darras 2025).
- How low blood pressure should go. Targets range from 140 or lower (Ramanadham 2015) to below 120 (Bassiri-Tehrani 2023). An older series found that sealing vessels at normal pressure during surgery mattered most, and pressure before or after surgery did not change the rate (Rees 1994).
What is new
- Surgeons now stack measures. Blood pressure control, TXA, glue and the net together brought one practice to about 3 hematomas per 1,000 lifts, with no control group (Lazzeri Domar 2026).
- The net now has a randomized trial and pooled results behind it (Ismail 2025, Ribeiro 2026).
- With modern protocols, men no longer bled more often than women in a matched comparison (Vishwanath 2026).
What is still unknown
- Which add-on works best. In deep plane lifts no single one was clearly better (Azzi 2026).
- How much each measure adds on its own. Most studies compare a surgeon's recent patients with earlier ones, and strong trials are few (Cason 2021).
- The best TXA dose and route (Alenazi 2024).
