1.Hymenal repair: The hymen is a petal-like protrusion of the mucous membrane at the vaginal opening, which can develop a small fissure due to sexual intercourse, trauma and strenuous activity. The procedure involves artificially creating a new wound at the hymenal fissure and then suturing the mucous membrane together to heal it and form a new hymen. 2.Vaginal narrowing: Applicable people include: people whose sexual life is affected by loose vagina, people who have constipation or tension incontinence after giving birth, and people who have old vaginal laceration with loose vagina. In addition to narrowing the vaginal opening and tightening the vaginal mucosa, it is more important to separate the torn and thinned muscles and tighten the sutures in place so as to repair and rebuild them. 3, labia minora plastic surgery: labia minora is located in the inner side of the labia majora, left and right two pieces. If the labia minora is too large and hangs outside the perineum, it is easy to rub when walking, triggering skin mucous membrane erosion and bringing inconvenience to daily life. The surgical method is to partially remove the oversized labia minora. 4.Surgical precautions: (1) Pre-operative routine blood, pre-operative four items, and routine leucorrhoea examination. (2) The surgery is best done 3-7 days after menstruation. (3) Take antibiotics routinely for 5-7 days after surgery. (4) Since the perineum is rich in blood vessels and loose tissues, hematoma and severe swelling may easily occur after surgery. It is better to lie down for 2-3 days after surgery to facilitate smooth recovery. (5) Pay attention to vulvar hygiene, and pay attention to cleaning and disinfection after each urination and defecation. Method: Dilute 5ml of iodophor 10 times with warm water, soak a piece of gauze and wash the perineum. (6) Keep the bowels unobstructed. (7) Don’t do strenuous sports activities and don’t ride a bicycle for a month to avoid reopening the suture wound. (8) No sexual intercourse for 2 months after vaginal tightening.
