[Summary]



Hymen hole shape, size and film thickness, varies from person to person. Hole in the general hymen, a Banruxing, occasionally emerging filters will be hymen hole divided into two halves around, said septal hymen or Double hymen. Also a sieve-like membrane covering the vagina in the mouth, said cribriform hymen. If hymen convolution of overfishing, a non-porous hymen, which is imperforate hymen, female genital mutilation dysplasia is relatively common.



[Diagnosis]




Wang also at very different thickness, and some thin, it seems paper, while others are thick (1 to 1.5 cm). Two mucosa in the middle of interstitial collagen can be rich in fiber and smooth muscle, can be mixed with dual of renal tissue components. Whether clinical symptoms appear, according to divide completely determined whether hole. Complete mechanic at small see, the majority of the cross at a central hole, and sometimes only through the small probe, the outflow of blood can be asymptomatic occurred until marriage for sexual intercourse difficult or delivery and fetal head doomed sister found. If no holes, once due to the onset of menstruation and retention symptoms. In the vaginal examination revealed at Yokota, the first mechanic at attention (often in the central part) there are small, porosity can be used to probe jack, exploration holes above the width and depth of the vagina to the diagnosis.


[Treatment]




Surgical resection, with holes for the base, to make X-shaped incision around until the vaginal wall, divide thin, circular excision divide redundant organizations, the incision will be a two-tier basement mucosa and some free, vertical-shaped suture, the margin of suture was serrated, not a plane, to forestall future narrow ring. If divide thick, mucous membrane should be in the outer surface for X-shaped incision, at the depth of horizontal thickness of 1 / 2, separation flap, and then to cross the inner transverse incision, Xian, four pairs of interwoven mosaic flap Suture, the more scar contracture after and protected from restenosis. If pregnancy after childbirth are often unable to proceed smoothly, and to put an end to be taken cesarean section delivery.
