Introduction: With aging, the vulvar tissue loses its vitality and elasticity due to collagen fibers fatigue. Such changes and functional characteristics of the external genitalia often cause negative psychological effects resulting in impeded sexual function. The objective of this study is to evaluate the safety and efficacy of a radio frequency (RF) device when used for treating labial laxity and for improvement of female sexual fuction.
Materials and methods: Using a monopolar RF device, 19 women received four once-a-week treatments. Images taken at the baseline and at the 1-month follow-up were evaluated for improvement in vulvar appearance on a scale of 0-3. The female sexual function index (FSFI) scores were calculated and compared between the baseline, the 1-month follow-up visit, and the 12-month follow-up visit.
Results: Average improvement in the vulvar appearance according to the patients and the physician was 2.00 ± 0.58 and 1.79 ± 0.54, respectively. Both values represent "moderate change" according to the applied scale. The average FSFI increased by 9.79 ± 4.35 and 7.10 ± 5.17 when comparing the baseline to the 1-month and the 12-month follow-up, respectively. No adverse events were reported.
Discussion: Efficacy and safety of the investigated device were proven. Longevity of results was proven by the 12-month follow-up.
