Absorbable facial suspension sutures made of poly-l-actic acid (PLLA) and poly-lactide-co-glycolide (PGLA) offer benefits to patients with moderate facial aging who require more correction than can be achieved with injectable soft tissue fillers, according to an evidence review of suture lift technologies published in the Journal of Drugs in Dermatology (July 2017).
A group of U.S.-based dermatologists and plastic surgeons convened to create an expert consensus on the use of a new-generation PLLA/PGLA absorbable suspension technology (Silhouette InstaLift). They performed a PubMed and Cochrane Library search of studies published between January 1, 2009 and April 30, 2016. The study review revealed that the introduction of absorbable PLLA/PGLA sutures (vs. non-absorbable polypropylene threads) reduced complications while offering longevity of results—1.5 to 2 years—and that patient selection and proper vector design are key factors in achieving optimal outcomes.
The consensus reached on ideal candidates for the procedure included: 35 to 65 years of age; good facial tissue quality and good pliability without excessive fibrosis and sun damage; sufficient skin thickness. The authors discouraged the use of facial suspension sutures in those with heavy faces.
Further consensus was reached on the use of the sutures in combination with other aesthetic procedures with the authors determining that: “The device by Sinclair Pharma can be combined with other treatments, such as botulinum toxins, dermal fillers and energy-based devices.”
