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.
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.
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.
Efficacy and safety of the investigated device were proven. Longevity of results was proven by the 12-month follow-up.
随着年龄增长，由于胶原纤维疲劳，外阴组织会失去活力和弹性。外生殖器的这些变化及其功能特征常常会产生负面心理影响，导致性功能障碍。本研究的目的是评估一种射频（RF）设备用于治疗阴唇松弛和改善女性性功能时的安全性和有效性。
19名女性使用单极射频设备，每周接受一次，共进行四次治疗。对基线时和1个月随访时拍摄的图像进行评估，以外阴外观改善情况按0 - 3级评分。计算并比较基线、1个月随访和12个月随访时的女性性功能指数（FSFI）得分。
根据患者和医生评估，外阴外观的平均改善分别为2.00 ± 0.58和1.79 ± 0.54。根据所应用的评分标准，这两个值均代表“中度变化”。将基线与1个月随访以及12个月随访相比较时，平均FSFI分别增加了9.79 ± 4.35和7.10 ± 5.17。未报告不良事件。
所研究设备的有效性和安全性得到了证实。12个月的随访证明了结果的持久性。
