Overview
Hybrid stromal vascular fraction (SVF) combines two mechanical preparations to raise cell counts in fat grafts. The author measured volume retention of facial micro-fat grafts enhanced with hybrid SVF and pure platelet-rich plasma (P-PRP), placed in the lid-cheek groove and malar fat pad during a facelift or necklift. Volume was tracked with Vectra 3D imaging over 12 months.
Findings
- 9 female patients; average age 65.6 years.
- Micro-fat mixed with M-SVF/M-SVM and PRP at a 5:1 volume ratio.
- Grafts placed in the palpebral-malar groove and malar fat pad units.
- Volume retention: 54.9% at 3 months, lowest at 38.4% at 5 to 7 months, highest at 69.5% at 10 to 12 months (P > .05).
- Investigator Global Assessment Improvement Scale scores were assessed; the abstract does not give them.
- No long-term side effects or complications were reported.
- The author states the associations are observational only; a causal link cannot be established in this uncontrolled trial.
- Level of evidence: 4.
What it means for a patient
- Fat grafted to the lid-cheek area during a facelift lost and then regained measured volume over a year in this small group.
- The changes over time were not statistically significant.
- No long-term complications were reported in patients older than 55.
- Limits: 9 patients, no control group, and the author advises caution until randomized trials are done.
Why this paper matters
It reports early volume data for fat grafts enhanced with hybrid SVF and platelets during facelift. The author presents it as preliminary and hypothesis-generating, not as proof of benefit.
Terms
- Micro-fat grafting: moving small particles of a patient's own fat to add volume.
- Stromal vascular fraction (SVF): a cell-rich portion separated from fat tissue.
- Platelet-rich plasma (PRP): a concentrate of platelets from the patient's own blood.
- Vectra: a 3D camera system that measures facial volume.
- Palpebral-malar groove: the crease between the lower eyelid and the cheek.
- Malar fat pad: the fat pad over the cheekbone.
- Volume retention: the share of injected fat volume still present at a later time.
- Uncontrolled trial: a study with no comparison group.
