The strategy for vaginal rejuvenation: CO₂ laser or vaginoplasty?

Vaginal laxity may result from trauma to the pelvic floor muscle, which may affect patients' sensation and quality of life. Vaginal rejuvenation, including surgical or nonsurgical interventions, aims to improve laxity. In this study, we aimed to establish a strategy for vaginal rejuvenation by comparing surgical and nonsurgical methods.

A retrospective clinical study was performed on patients who complained about vaginal laxity from 2017 to 2019. The degree of vaginal laxity severity was evaluated by vaginal examination in each patient. The patients were categorized as having a light, moderate or severe degree of vaginal laxity, and different correction methods were chosen accordingly. The Female Sexual Function Index (FSFI) questionnaire was administered to the patients preoperatively and at three months and one year after treatment.

Seventeen patients with severe-degree vaginal laxity were treated with vaginoplasty. The total FSFI score was 23.21±2.57 before the operation and significantly increased to 29.36±1.84 (P<0.01) at one year after surgery. Eleven patients with moderate-degree vaginal laxity were treated with vaginoplasty and had a significant improvement in the total FSFI score at one year after surgery (29.86±1.74, P<0.01) compared with the FSFI score before surgery (23.41±2.84). Three patients with moderate-degree vaginal laxity were treated with a CO₂ laser and tended to have increased FSFI scores but did not show significant improvement after the operation. CO₂ laser treatment was performed on 16 patients with light-degree vaginal laxity. The total FSFI score improved from 23.76±2.35 to 26.16±2.58 at one year (P<0.05).

The strategy for vaginal rejuvenation should be selected based on the degree of vaginal laxity severity. Surgical treatment is suitable for severe- and moderate-degree vaginal laxity while nonsurgical treatment is suitable for light-degree vaginal laxity.
