Several methods for treating congenital absence of vagina

The principle of treatment for congenital absence of vagina is to reconstruct the vagina. There are various methods for artificial vaginal formation, including non-surgical treatment, which is to gradually push the closed vestibular mucosa in the normal vaginal position along the vaginal axis to the head side to form an artificial cavity. This method requires a long treatment time and the artificial vagina formed is short. If the tissue elasticity is poor, it is difficult to succeed and has been basically abandoned.

Surgical treatment mainly involves separating the urethra, bladder and rectum to form an artificial cavity, using different methods to find an appropriate cavity wound covering and reconstructing the vagina.

In the free skin graft method, skin flaps are taken from the perineum or thigh to cover artificial acupuncture points. After the operation, a hard vaginal mold needs to be used for a long time to expand the artificial vagina to prevent the artificial cavity of the transplanted skin graft from contracting, which increases the patient's pain. Moreover, the skin is not a mucous membrane, and the tissue properties are too different for the man to adapt.

The artificial acupuncture points are covered with the amniotic membrane, which is a foreign tissue and cannot survive. It can only be a temporary cover and will eventually heal as a scar. It also does not conform to the tissue characteristics of the mucous membrane and cannot be used for sexual intercourse.

The disadvantage of using pelvic peritoneum to cover artificial acupuncture points is that sexual intercourse is painful and prone to infection. Although using labia skin flaps to cover artificial acupuncture points conforms to the tissue characteristics of the mucosa and allows sexual intercourse, it destroys the normal shape of the vulva, which can be seen by the man at a glance and affects his psychology.
