A Retrospective Study of SVF-gel Compared With Nanofat Combined With High-density Fat in the Treatment of Early Periorbital Aging.

Purpose: To compare the effectiveness of transplantation with stromal vascular fraction (SVF)-gel or nanofat combined with high-density fat prepared with the Coleman technique (nanofat+high-density fat) to restore volume in the periorbital region or for periorbital rejuvenation in early periorbital aging.

Methods: This retrospective study included 103 patients who received a transplant of SVF-gel (n = 58) or nanofat+high-density fat (n = 45) to restore volume in the periorbital region (n = 85) or for periorbital rejuvenation (n = 18) in our hospital between January 2016 and January 2020. Patient satisfaction and the reoperation rate were evaluated.

Results: All patients had improved periorbital contouring and augmentation. Among the patients that received treatment to restore volume in the periorbital region, 17% and 65.9% of patients administered SVF-gel were very satisfied or satisfied, and 5.3% and 44.7% of patients administered nanofat+high-density fat were very satisfied or satisfied.

Patients: administered SVF-gel were significantly more satisfied than patients administered nanofat+high-density fat with improvements in periorbital contouring ( p < 0.05). Among the patients that received treatment for periorbital rejuvenation, 54.5% and 27.3% of patients administered SVF-gel were very satisfied or satisfied, and 28.6% and 42.8% of patients administered nanofat+high-density fat were very satisfied or satisfied. There was no significant difference between groups ( p > 0.05). Some patients underwent a second operation after 3 to 8 months. Patients administered SVF-gel to restore volume in the periorbital region had a significantly lower reoperation rate than patients administered nanofat+high-density fat (12.7% [6/47] vs. 34.2% [13/38]; p < 0.05). There was no significant difference in the reoperation rate in patients treated for periorbital rejuvenation (9.1% [1/11] vs. 14.3% [1/7]; p > 0.05).

Conclusion: SVF-gel and nanofat+high-density fat are effective for restoring volume in the periorbital region and for periorbital rejuvenation in early periorbital aging. The reoperation rate was significantly lower and patient satisfaction scores were significantly higher in patients administered SVF-gel to restore volume in the periorbital region compared with patients administered nanofat+high-density fat.
