Часто задаваемые вопросы

What is the fornix of the vagina?
The fornix of the vagina refers to the deepest recesses of the vaginal vault — the spaces formed around the vaginal portion of the cervix (the ectocervix). The fornix is divided into four regions: the posterior fornix (deepest, adjacent to the rectouterine pouch), the anterior fornix (adjacent to the vesicouterine pouch), and the two lateral fornices. The posterior fornix is clinically significant because it is the closest vaginal point to the peritoneal cavity.
Why is the posterior fornix clinically important?
The posterior fornix is separated from the rectouterine pouch (pouch of Douglas) by only a thin layer of peritoneum and vaginal wall. This proximity has several clinical implications: free fluid (blood, pus, or ascites) in the peritoneal cavity can be felt as a bulge in the posterior fornix, culdocentesis (needle aspiration through the posterior fornix) can sample peritoneal fluid, and transvaginal oocyte retrieval during IVF accesses follicles through the fornix.
What structures are accessible via the vaginal fornix?
The vaginal fornix provides clinical access to several anatomical structures. The posterior fornix is adjacent to the rectouterine pouch, making it useful for draining pelvic abscesses. The cervix projects into the central fornix, making colposcopy and cervical biopsies accessible. The lateral fornices are near the uterosacral ligaments and the parametrium, regions important in gynecological surgery and cancer staging.
