The doctor will decide on treatment based on the cause.
If the patient has an imperforate hymen, the urologist will make a simple cut. No anesthesia is needed with this method. Once drainage occurs, the patient will be checked for other issues.
If the patient has a high transverse septum, treatment will depend on its thickness and location. Depending on where it is, the surgeon can cut upwards to remove it, reconnecting the upper and lower vagina. Or, it may call for surgical excision. Certain methods are used to prevent vaginal narrowing.
The patient's own skin or part of the intestine can be used to bridge the gap between the upper and lower vagina. A mold can be placed in the vagina after surgery with a hollow center to allow menstrual flow.
