Vaginal tightening is performed by exposing the vaginal wall under strict sterile sterilization, incising and peeling the mucosa, removing the excess vaginal mucosal tissue, repairing the damaged muscles, then suturing the mucosal tissue, performing plastic surgery and suturing the broken ends of the vaginal mucosal stump. Vaginal tightening surgery is suitable for postpartum women, women with vaginal laxity, and patients who have experienced a decrease in vaginal contraction and vaginal laxity due to factors such as childbirth or trauma that have caused tearing or thinning of the muscles surrounding the vagina. Vaginal tightening has a significant improvement on the patient’s quality of life, but the duration of its effect is significantly and positively correlated with the choice of the procedure. Most injectable vaginal rejuvenation treatments are only effective for about six months to a year. With surgical vaginal tightening treatments, for example, 3D vaginal tightening with full preservation of the mucous membrane of the posterior vaginal wall, the results can be maintained for a longer period of time if the patient is able to practice for a long time after the surgery, most patients can maintain their results for about 3-5 years. If patients rely on the surgical result without functional exercises, the natural aging process is unavoidable and the result will be shorter.
