Treatment of periorbital wrinkles with fractional microneedle bipolar radiofrequency and 1550 NM ER: Grass fractional photothermalysis laser: A comparative study
Abstract:
Periorbital wrinkles is the significant problem always seen in the aging process. Nowadays, there are many periorbital rejuvenation procedures, especially fractional Er:grass 1550 nm photothermolysis laser andfractional bipolar radiofrequency with microneedle. Both systems are well known in their efficacy and safety of wrinkle reduction in this sensitive area with the different efficacy and side effects. According to this reason, the objective of this thesis is to compare the efficacy and safety betweenfractional bipolar radiofrequency with microneedle and fractional Er:grass 1550 nm photothermolysis laser in the treatment of periorbital wrinkles. The study conducted in 20 people who havemild to moderate periorbital wrinkles according to Fitzpatricks wrinkle scoring scale with age between 30-60years. Split-face randomized clinical trial was done and perform 3 treatments with fractional bipolar radiofrequency with microneedle or fractional Er:grass 1550 nm photothermolysis laser treatment on either side at 4-week intervals.Visioscan®VC98 was used to evaluate wrinkle score in week 0, week 4, week 8 and week 12. The clinical improvement score, side effect andpatient satisfaction score were performed in the end of the study. We found that there was significant improvement in 4 weeks after second treatment in both group. (p-value=0.003 infractional bipolar radiofrequency with microneedle group and p-value=0.005 infractional Er:grass 1550nm photothermolysis laser group, Pair T-test) There was no significant difference of wrinkle improvement between both procedures (p-value=0.797, Unpair T-test). In clinical improvement score evaluation, fractional bipolar radiofrequency with microneedle gave the clearly improvement of the periorbital wrinkles (51%-100% improvement) in 28% while 25% was assessed in Fractional Er:grass 1550 nm photothermolysis laser. Lesser down time and pain score were found in fractional bipolar radiofrequency with microneedle group. However, both treatment groups had the same number of subjects experienced in darkening of melasma.
