There are two kinds of diaphragm: complete diaphragm and incomplete diaphragm, which mostly occur in the middle and upper segment of vagina. The thickness of diaphragm varies from 1 to 1.5 cm. A complete diaphragm is rare. It can lead to menstrual blood retention, and the symptoms are similar to imperforate hymen. On examination, a bloody diaphragm protrudes above the hymen ring. Diaphragmatic insufficiency is common, and there is often a small hole in the center or side of the diaphragm through which menstrual blood flows out. High incomplete diaphragm is generally asymptomatic, which does not affect sexual life and pregnancy, but can affect the decline of fetal presentation during delivery; Diaphragmatic insufficiency in the lower position, because of unsatisfactory sexual life after marriage, often go to see a doctor.

If the diaphragm is thin and soft, it is feasible to cut the diaphragm, remove excess tissue and sew the edge of the incision. If the diaphragm tissue is thick and the elasticity is poor, the vaginal model should be placed for a period of time after diaphragm resection to continue to expand the vagina to prevent stenosis and adhesion. If the diaphragm is found to hinder the descent of presentation during delivery, it can be cut if the diaphragm is thin; After the fetus is born, check the edge of the incision and suture it if there is bleeding. If the diaphragm is thick, cesarean section is necessary.
