Fractional CO2 Laser for Vulvovaginal Atrophy.

To evaluate the short term efficacy and safety of Fractional CO2 laser for the treatment of vulvovaginal atrophy.From March 2015 to October 2015, 112 menopausal women were recruited. All women with VVA were treated by using Fractional CO2 laser; power 30 watts, 1-3 stacks with 360° vaginal probe for 3 consecutive times, 4 weeks apart. Before laser treatment, the subjective measurement of VVA symptoms was evaluated by using a questionnaire and the objective measurements were evaluated by using pH paper and VMI. Visual analog pain-score was used to scaling their discomfort during and immediately after each treatment. At 3 months after the last procedure, the subjective and objective measurements were re-assessed. Any short-term and long-term adverse events were recorded. Statistical analysis was performed by using SPSS program with p-value <0.05.The median of pre-screening VVA symptom score was 4 and the most bothersome symptom was the “feeling of dryness around vulvar”. There was a significant reduction of the score after laser treatment. The average percentage of pretreatment VMI was 34.7±16.1% and at one and three months after complete laser course, it was significantly increased with the mean change of 25.0±12.2% and 34.8±15.5%, respectively. For the vaginal pH, the average pH before treatment was 7.5±1.0 and the average decrement after 3 months was 0.9±1.3 with statistical significance, p-value <0.01. There were no serious complications and all were satisfied with the treatment.Fractional CO2 laser could ameliorate the VVA symptoms with at least 3 months of long lasting improvement of vaginal health with safety.
