Efficacy and safety of monopolar radiofrequency for the improvement of facial skin laxity and rhytides: A systematic review of clinical trials / The Health Sciences Journal

INTRODUCTION: There is a consistent increase in the interest and demand for non-invasive modalities toimprove facial skin laxity and rhytides. Monopolar radiofrequency is one of such non-invasive modalities.This systematic review aimed to determine the efficacy and safety of monopolar radiofrequency inimproving facial rhytides and skin laxity.METHODS: Clinical studies that assessed the efficacy of monopolar radiofrequency to address clinicallyobservable facial rhytides and skin laxity were included. Outcome measures included improvementin rhytides and skin laxity as documented by patient satisfaction scores, and investigator and third-personobserver ratings based on clinical photographs and clinical scales.RESULTS: Three studies involving 29 participants were included in this review. All studies reported 25-50% improvement in facial rhytides and skin laxity. Participants from the three studies were satisfiedwith the results. Transient erythema was reported in several patients.CONCLUSION: Monopolar radiofrequency appears to be beneficial and safe for patients with facialrhytides and skin laxity. However, the evidence is inconclusive due to problems in the methodologicalquality of each trial and the heterogeneity of the studies included in this review.

Microagulhamento associado a fatores de crescimento e vitamina C no tratamento de estrias, fibro edema gelóide e flacidez tissular na região glútea / Microneedling associated to growth factors and ascorbic acid in the treatment of cellulite, striae distensae and skin laxity in the gluteal region

O microagulhamento é usado no tratamento de diversas afecções estéticas promovendo estímulo de colágeno. O objetivo deste trabalho foi averiguar a eficácia da associação do microagulhamento a fatores de crescimento e a vitamina C em diferentes afecções estéticas na região glútea. Foram realizadas 4 sessões de microagulhamento com intervalo de 21 dias entre as sessões. Percebeu-se significativa melhora na flacidez tissular, no fibro edema gelóide (FEG) e nas estrias e o microagulhamento mostrou-se uma técnica segura e eficaz para tratementos dessas disfunções estéticas.

The microneedling is used in the treatment of several aesthetic affections promoting collagen stimulation. The objective of this study was to verify the efficacy of the association of microneedling, growth factors and ascorbic acid in aesthetic affections in the gluteal region. Four sessions of microneedling were performed with a 21-day interval between the sessions, in which a significant improvement on skin laxity, cellulite and striae distensae was observed in the result and proved that the microneedling is to be a safe and effective technique for treating these aesthetic dysfunctions.

Two Cases of Reconstruction with Modified Keystone Flap on the Lower Extremity / 대한피부과학회지

Even though several techniques are available for repairing lower extremity skin defects, it is hard to challenge the advantages of local flaps (advancement, rotation, or transposition) due to lack of skin laxity of lower extremities. Modified keystone flap (MKF) is a simple and effective method of closing a large skin defect. It is especially useful for wound closure in circumstances where the defects show limited skin laxity. Compared to the keystone flap (KF), MKF has many advantages, including quick healing time, high flap viability, minimal postoperative pain, and excellent aesthetic results. Here, we report two cases of reconstruction of large skin defects of the lower extremities using MKF with satisfactory results.
