The hymen is a thin fold of mucous membrane located at the entrance of the vagina and is often ruptured due to strenuous exercise, accidents, sexual intercourse, etc. A ruptured hymen can cause great psychological stress to unmarried women. Surgical repair of the hymen is the only effective method available. There are many methods of hymenal repair: the tile method, the purse method, the vaginal mucosa repair method, the local mucosal flap method, and the longitudinal splitting and double suturing method. The procedure is based on the degree of hymenal fracture. Pre-operative preparation: 3-5 days after menstruation, routine blood and coagulation tests, and leucorrhoea tests. Three days before surgery, use one-thousandth of potassium permanganate solution or jelqing to take a sitz bath or perform vaginal douching. Post-operative care: take oral antibiotics for three days after surgery, and wash the vulva with one-thousandth of potassium permanganate solution or cleansing once a day to keep it clean and dry. Take rest for 3 days after surgery, wear loose cotton underwear and keep the area clean and not too wet. The first 3 days of post-operative care is the most important part to ensure the success of the operation. The squatting, leg-splitting and leg-lifting movements may involve the hymen and affect its healing, so try to take rest for the first 3 days after surgery, preferably in bed, and avoid movements that affect wound healing. Since the hymen is easily affected by the excretion of the urethra, anus and vagina, it is very important to eat a light, non-slag diet and keep the local wound dry as much as possible after surgery, and to reduce unnecessary washing. Avoid squatting, leg lifting, leg splitting, etc. and bicycle riding for 2 weeks after surgery. It is not necessary to remove the stitches for a review about a week after surgery. If the bleeding is heavy or the first menstrual flow is not smooth after surgery, you need to come to the hospital for follow-up.
