Treatment of microperforate hymen with serial dilation: a novel approach

Microperforate and imperforate hymens are one of the most common causes of vaginal outflow obstruction in the adolescent population. To date, these hymen anomalies are traditionally treated by hymenectomy with a cruciate excision.

We report 2 cases of adolescent women with a microperforate hymen who were successfully and minimally invasively treated with progressive dilation with Hegar cervical dilators until a number 23 dilator was reached under anesthesia in the OR.

Minimally invasive treatment of microperforate hymen with the use of progressive cervical dilators may be an alternative technique to the traditional excisional hymenectomy. Our patients reported satisfaction and minimal postoperative pain or scarring at 2 weeks and 6 months after the procedure. This technique can be an additional option for all women, especially those with cultural beliefs in virginity.
