Most cysts in the vaginal opening are retention cysts caused by inflammation that blocks the opening of the gland. There are also some cysts that are caused by lipomas or sweat gland tumors. In the case of small cysts, they can be treated by aspirating the cystic fluid with a needle and then injecting anhydrous alcohol to destroy the gland. For larger cysts, which may affect sexual life and cause painful intercourse or even prevent childbirth, surgical excision is needed and cyst excision and drainage can be performed, but this method is prone to recurrence. After surgery, you should pay attention to vulva hygiene, you can apply potassium permanganate to fumigate your vulva every day, and your diet should be careful to avoid spicy foods. Pay attention to menstrual hygiene, change sanitary napkins during menstruation, keep the vulva clean and dry, and do not use hot water to wash the vulva to prevent vaginal cysts from occurring.
