Micro Superficial Enhanced Fluid Fat Injection technique effective for facial rejuvenation

The Micro Superficial Enhanced Fluid Fat Injection, or M-SEFFI, technique for skin rejuvenation and volume enhancement has high patient and surgeon satisfaction, according to study results published in Aesthetic Surgery Journal.

The M-SEFFI technique is an extension of the Superficial Enhanced Fluid Fat Injection (SEFFI) technique that harvests smoother fat tissue using a 15-cm long multiperforated cannula with 0.3-mm ports compared with the 0.5-mm or 0.8-mm ports used in the SEFFI technique. The smoother fat harvested using M-SEFFI does not require postharvest tissue manipulation. The technique includes the addition of plasma-rich platelets to enhance the harvest tissue.

The researchers performed the technique on 65 patients between June 2014 and July 2015. There were 58 women and seven men with a mean age of 49.7 years (range, 34-63 years). Photos were taken preoperatively and at 1, 3 and 6 months following the procedure to be assessed by both the surgeons and the patients. The score system was defined as 1 for “no effect,” 2 for “fair effect,” 3 for “good effect” and 4 for “excellent effect.”

The mean harvesting procedure time was 8.6 minutes (range, 6-23 minutes) with an average of 6.08 mL (range, 0.5-24 mL) of adipose tissue harvested. The mean implanted volume following the addition of plasma-rich platelets was 7.3 mL (range, 0.6-29 mL). No intraoperative complications were recorded.

At 1-month follow-up, 65 patients rated their results at a mean score of 3.74. At 3 months, 59 returning patients gave a mean score of 3.17. At 6 months, 48 returning patients gave a mean score of 2.6. The surgeons scored the results as 3.52 at 1 month, 3.39 at 3 months and 3.06 at 6 months.

“The harvested tissue is viable, as proven at histological and cell culture analysis, has a reduced risk for lumpiness after superficial injection, promises volume enhancement, and is appreciated by both surgeons and patients,” the researchers wrote. “The filler capacity of the micro fat with viable adipocytes, along with the improved fluidity and contribution to the vitality of the [plasma-rich platelets] are key to the success of M-SEFFI.” – by Talitha Bennett
