Abstract Objectives: To evaluate Microablative Fractional Radiofrequency (MAFRF) as a possible option in treating vaginal atrophy. Methods: This was a randomized, controlled clinical trial with postmenopausal women diagnosed with vaginal atrophy. The treatment consisted of three sessions of MAFRF, compared to vaginal estrogen administration and an untreated control group. Assessments occurred at baseline and 90 days. The primary endpoints were sexual function, evaluated by the Female Sexual Function Index (FSFI), and vaginal health, assessed by the Vaginal Health Index (VHI). Secondary outcomes included vaginal microbiota composition (Nugent score) and epithelial cell maturation (Maturation Value ‒ MV). Results: One hundred and twenty women (40 in each group) were included. Concerning the FSFI, both groups, MAFRF (median 4.8 [3.6‒6.0]) and vaginal estrogen (mean 4.7 ± 1.1), experienced improved sexual desire when compared to the control group (median 3.6 [2.4‒4.8]). Regarding the total score of VHI, the authors observed an improvement in the mean of the MAFRF (23.7 ± 2.0) and vaginal estrogen groups (23.5 ± 1.9) when compared to the control (14.8 ± 2.9). The Nugent score was reduced in the MAFRF and estrogen groups (p < 0.01) compared to the control group. Lastly, the MV was modified after treatment with MAFRF (p < 0.01) and vaginal estrogen (p < 0.001). No differences existed between the MAFRF and vaginal estrogen groups in the studied variables. No adverse effects were reported following the MAFRF protocol. Conclusions: Radiofrequency was comparable in efficacy to estrogen administration for treating vulvovaginal atrophy. It deserves consideration as a viable option in managing this condition.

OBJECTIVES: We aimed to evaluate the effectiveness of microablative fractional radiofrequency (MAFRF) in the non-hormonal treatment of genitourinary syndrome of menopause. METHODS: We examined the cases of 55 postmenopausal women before and after treatment with regard to their vaginal health index (VHI), vaginal microbiota, vaginal pH, and cell maturation. Three applications of MAFRF were performed in the vagina/vaginal introitus. During the treatment, six vaginal smears were obtained and stained with the Papanicolaou stain for determining the degree of cell maturation and with Gram stain for classification of vaginal flora, as per the criteria of Spiegel and Amsel. For vaginal pH determination, pH indicator strips were applied against the vaginal wall. Statistical analysis was performed using SPSS for Windows (version 17.0). Data were reported as mean±standard deviation. The differences were analyzed using the statistical method of generalized estimation equations with autoregressive correlation structure “1” and robust standard errors. RESULTS: The mean age was 59.8±4.2 years, and the mean time of menopause was 15.4±4.5 years. After treatment, there was an increase in the percentage of Lactobacillus spp. (p<0.001). Consequently, there was a progressive decrease in vaginal pH during the treatment (p<0.001). Regarding cell maturation, there was a decrease in the percentage of parabasal cells (p=0.001) and an increase in the rate of superficial cells (p<0.001). Additionally, there was an improvement in the VHI index. The mean VHI values before and after treatment were 13.2±5.6 and 22.5±3.7, respectively (p<0.001). CONCLUSION: MAFRF treatment is well tolerated and leads to improvement in the vaginal microenvironment.
