Hymen repair is a more common intimate plastic surgery, through surgery can restore the normal shape of the hymen, but also to reduce the psychological burden of the patient. With the continuous development of technology, hymen repair styles are also diversifying, and the main methods of repair at present are tile law, penetration method, sandwich method, and original aperture restoration method. However, due to the hymen’s poor tissue fiber blood flow, postoperative wound tension, easy to be contaminated and nursing difficulties and many other reasons, the operation is difficult to be successful at once, especially the complex hymen rupture. Vaginal mucosal flap repair method can be used to treat patients with complex hymen rupture. I. Applicable people: 1, hymen ≥ 2 broken and at least one breach deep to the base of the hymen or even rupture to the vaginal mucosa of the female population. 2, hymen ≥ 2 broken and one of the breach is located in the truncation of the 12 o’clock female population. 3, hymen ≥ 2 broken and at least 1 rupture margin scar is large, excision scar direct suture can cause tension female population. 4, hymen obvious defect direct suture can cause high tension female population. Second, the surgical method: 1, the timing of the operation are selected in the menstrual period completely clean 3 to 5 days, such as perineum and vaginal inflammation should be cured inflammation, such as warts should be cured first, and no recurrence within 3 months. 2.3d before the operation, use the Pak Jie detergent, diluted with warm boiled water to rinse the vagina, 1 time/d. 3.Adopt the gynecological truncated position, and routinely disinfect and spread the towel. For larger defects or more obvious scar or deeper fissure, the author of the fissure at 12 o’clock of the truncal position used vaginal mucosal flap repair method. Specific operation steps: Make local infiltration anesthesia, use mosquito forceps to clamp the ends of the vaginal mucosa corresponding to the ruptured hymen, expose the triangular vaginal mucosa that needs to be trimmed away, enter the needle from the base of the vaginal orifice, and inject 1% lidocaine containing 0.1% epinephrine into the vaginal mucosa. After satisfactory anesthesia, a triangular vaginal mucosal flap of 1 to 2 cm in height was freed with ophthalmic scissors using the vaginal mucosa corresponding to the base of the ruptured hymen as the base, and the freed mucosal flap should be gradually thinned from the outside to the inside. The free mucosal flap should be thinned from outside to inside. The triangular mucosal flap that is slightly smaller than the free range should be trimmed to reserve the mucosal suture margins on both sides, and the reserved mucosal margins should be gradually reduced from outside to inside. The free vaginal mucosa is closed interruptedly from the inside out with 5-0 absorbable sutures. The inner edge of one side of the torn hymen and the outer edge of the opposite side are cut, and the submucosa is freed toward the margin of the cleft to form mucosal flaps on both sides of the hymen, and the hymen is closed interruptedly with 5-0 absorbable sutures in a tile-like fashion. If the scar is large, the scar should be completely cut out. If it is at the truncated 12 o’clock and the fissure has not reached the base, the fissure should be prolonged to the base first, and then processed according to the steps (2) to (4) above. As for the defect is smaller or shallower fissure for rupture, hymen base at 0.1% epinephrine 1% lidocaine local infiltration anesthesia appropriate trimming rupture edge to form a new trauma after 5-0 absorbable suture direct suture. After repairing the hymen hole to be able to pass a small finger is appropriate. Third, postoperative recovery: hymen repair recovery, postoperative bed rest is recommended for 1 week, 1 week need routine oral antibiotics, warm water to wash the perineum 1 ~ 2 times / d, especially after defecation, cleaning the surface of the hymenal wound coated with erythromycin ointment to prevent infection, and keep the local clean and dry. Hymen repair surgery should try to avoid squatting within 15d, the best use of sitting toilet when going to the toilet. After the surgery, you should eat more fruits to avoid constipation and hardening. Within 1 month after hymen repair surgery, don’t carry out activities that increase the tension of perineum such as riding bicycle. Come to our hospital for review 1 month after hymen repair to determine the effect of surgery. Fourth, method summary: hymen is a layer of membranous tissue structure of the vaginal opening, about 1 ~ 2mm thick, in the outside of the membrane, the inner surface of the membrane are moist mucous membrane, between the two layers of mucous membrane containing connective tissue, nerve fibers and tiny blood vessels, does not contain glands and muscle tissue. Most in the first sexual intercourse rupture, the initial rupture is located in the truncated position 4 points, 8 points, often fissure-like rupture. With the increase in the number or intensity of sexual intercourse, especially after abortion, mid-term induction of labor or even childbirth, making the hymen break aggravated, in the form of chunks or petals. If the hymenal defect is serious and the suture site is many, the suture tension will be more obvious, and even can’t be completely aligned, together with the special characteristics of the vaginal mucosa tissue structure, its anti-tension performance is poor, the tissue edema caused by the surgery and the cutting effect of the suture, which often leads to the suture edge in the healing process of the natural crack or any one of the actions that can cause an increase in the local tension can be triggered to the suture edge crack and lead to the surgical failure, due to the suture edge Because of the increased local tension and fibrosis aggravated by the cracking of the suture margin, the healing ability of reoperation is even worse. The more severe the hymenal breach, the lower the rate of phase I healing. The advantages of the vaginal mucosal flap repair method for patients with complex hymen rupture are more obvious, not only removing the newborn vaginal mucosal grooves, tightening the vagina, reducing the tension at the hymenal suture margins, increasing the blood supply at the rupture margins of the hymen, and enhancing the healing ability, but also the vaginal mucosal anesthesia avoids tissue edema caused by the direct anesthesia of the hymen, and improves the resistance to the tension of the mucosa.
