Background:
Vaginal laxity, usually accompanied with prolapse symptoms, affects women's sexual satisfaction and quality of life. Vaginal tightening surgery aims to reinforce perivaginal muscle strength and restore normal vaginal anatomy.
Objectives:
The aim of this study was to introduce a new surgical approach to vaginal tightening that uses acellular dermal matrix.
Methods:
In this retrospective study, data from 80 patients with vaginal laxity who underwent surgery between April 2017 and April 2021 were analyzed. Three-dimensional transvaginal ultrasound was performed and the Female Sexual Function Index was evaluated.
Results:
The mean age of the patients was 44.6 years. The mean patient follow-up was 13.2 months. No infection, rectovaginal fistula, or implant explantation occurred. Transvaginal ultrasound examination demonstrated a significant reduction of introital diameter on a maximum Valsalva maneuver (2.3 cm vs 4.1 cm; P < 0.05) and the reconstruction of acute vaginal angulation. The Female Sexual Function Index orgasm subscore increased significantly.
Conclusions:
Vaginal tightening with acellular dermal matrix is a minimally invasive surgery that offers a safe and effective treatment for patients with vaginal laxity.
