RESUMO
Objective:To evaluate the efficacy of monopolar radiofrequency combined with ultrasound for abdominal obesity.Methods:A total of 24 patients (4 males, 20 females, average age was 35 years) were given monopolar radiofrequency combined with ultrasound treatment four times at (10±4) day interval at Beijing Friendship Hospital during December 2015 to December 2016. Body weight and abdomen circumferences were recorded before and after each treatment. Subcutaneous adipose tissue thickness was measured with B ultrasound at baseline and after the last treatment. 2 months after the last treatment, a third party would assess the improvement; at the same time, volunteers would assess the outcome with Global Aesthetic International Scale. Blood lipid level, liver function and renal function were tested at baseline and after the third treatment. All the treatment related adverse effect would be noted as well.Results:There was no significant difference of body weight after the treatment. The abdomen circumferences were decreased at 2 month after the last treatment, especially for the navel one, which decreased from (96.14±11.92) cm at baseline to (93.82±10.77) cm, t=4.21, P<0.05. And the subcutaneous adipose tissue thickness also decreased from (25.56±4.3) mm to (24.31±3.77) mm, ( t=6.26, P<0.05). 2 months after the last treatment, 16 volunteers were graded as 1-25% improvement, 8 volunteers were graded as 26%-50% improvement. According to GAIS, 2, 18 and 4 volunteers assess the outcome was regarded as 0 score, 1 score and 2 score respectively. The treatments showed no influence to blood lipid level, liver function and renal function. The treatment processing was tolerated well and no side effect were noted. Conclusions:Monopolar radiofrequency combined with ultrasound treatment for abdominal obesity is effective and safe.
RESUMO
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.

HumanosRESUMO
BACKGROUND: Over the past 10 years, monopolar radiofrequency (MRF) technology has been widely used by dermatologists as a valuable modality to effectively tighten and rejuvenate photoaged skin. It also has the benefit of a short recovery time. OBJECTIVE: Using an objective parameter, this study aimed to assess the efficacy and safety of MRF, which is the basic modality of radiofrequency technologies, for treatment of periorbital wrinkles in Korean patients. METHODS: We enrolled 70 middle-aged female patients with periorbital wrinkles for this study. Each patient underwent triple sessions of MRF treatment in the periorbital region, separated by 2-week intervals. Clinical photographs were obtained, and the areas of wrinkles were measured using a Robo Skin Analyzer CS50 (Inforward Inc., Japan) at baseline and 4 weeks after the final treatment session. RESULTS: Significant reduction in the mean area of periorbital wrinkles was detected at 1-month follow-up (80.64±28.96 mm2) compared to baseline (95.08±31.93 mm2). The improvement ratio of the wrinkle area was 15.19%. Pain during procedure seemed to be tolerable without any local anesthesia for all patients. Transient mild erythema was the only side effect reported during the study. CONCLUSION: In conclusion, MRF could still be an attractive modality for Korean patients with periorbital wrinkles if the treatment is conducted repeatedly with sufficient energy and proper intervals.
