Micro-Coring: A Novel Approach to Perioral Rejuvenation.

Abstract

A long philtrum and poor perioral skin quality are stigmata of the aging face. Micro-coring is a novel technology that allows for scarless skin removal. This study aimed to determine if micro-coring can shorten the philtrum and improve perioral skin quality. A retrospective cohort study was performed on subjects who underwent facelift with perioral micro-coring and age/BMI-matched control patients who underwent facelift alone. Preoperative and postoperative three-dimensional facial imaging was performed. Standard perioral distances and percent change were calculated. Perioral skin quality was evaluated by blinded raters using the Scientific Assessment Scale of Skin Quality (SASSQ) and Global Aesthetic Improvement Scale (GAIS). Thirteen subjects and thirteen controls were included with a mean follow-up of 8.9 months (range 3.0-21.5). Subjects had significantly shorter mean philtral length postoperatively as compared to preoperatively, with an average decrease of 6.18% (±2.25%) (p<0.05). Controls did not experience significant changes in philtrum length (p>0.05). Postoperative philtrum length was significantly shorter in subjects as compared to controls (p<0.05). There were no significant changes in other perioral measurements. Perioral skin elasticity and wrinkles significantly improved in subjects as compared to controls and subjects had significantly greater GAIS scores (p<0.05). Micro-coring can achieve perioral rejuvenation through measurable shortening of the philtrum and observable improvement in skin quality. Non-surgical techniques continue to find new ways to achieve aesthetic goals without significant recovery or scarring and offer value to patients and clinicians.
