Vaginal tightening surgery generally has a laser, injection filling, local excision and other surgical methods, each has its own advantages and disadvantages, need to be selected according to the specific circumstances of the individual. 1. Laser: It is a minimally invasive surgical treatment method, which is effective for mild vaginal laxity. However, the choice of laser energy is very important, once the laser energy is too large, penetrating the front wall of the vagina may cause vaginal and urethral fistula, penetrating the back wall of the vagina may cause vaginal rectal fistula. 2. Injectable fillers: fat, hyaluronic acid and other materials, fill the surrounding cavity, to reduce the size of the vaginal cavity, to achieve the purpose of tightening, but the maintenance effect is short. If the fat or hyaluronic acid gets into the blood when injecting, it may form embolism, which may cause adverse consequences to the patients. 3. Local excision: Including the traditional vaginal tightening surgery, part of the vaginal mucosa is removed to reduce the size of the vaginal canal. Newer surgeries use the preservation of the vaginal mucosa and muscle reconstruction for vaginal tightening. For more information, please consult your doctor.
