Half-fascia

from Wikipedia, the free encyclopedia
Halban'sche fascia , according to the nomenclature also septum vesicovaginale , between the urethra or bladder , vesica urinaria and (above or ventral to the) vagina (colored pink) located connective tissue space , sagital incision plane

The Halban-fascia , also septum vesicovaginale , is a connective tissue space, which is named after the gynecologist Josef von Halban as a descriptor and extends between the trigonum vesica of the urinary bladder dorsally and the anterior, ventral part of the vagina. Anteriorly from the bladder and the vagina coming, then he continues as a septum uretrovaginale between the female urethra and vagina or in the vestibule , vaginal vestibule , continued.

Embryogenesis, Anatomy and Function

The vesicovaginal septum is a mesenchymal lamina with a fibroelastic layer of collagenous , elastic and smooth muscle fibers, an abundant blood supply (capillarization) and a nerve supply with frilled bodies and pseudocorporeal nerve endings. After both sides of the side ( lateral ) she goes to endopelvic fascia over - these again inserted on the tank wall at the tendinous arch . It is assumed that this structure develops in the early embryonic differentiation from the same mesenchymal tissue of origin as the erectile tissue around the urethra , corpus spongiosum urethrae .

There should be two female intravaginal erogenous zones in the area of ​​the half-fascia :

  • G-spot or Graefenberg zone in the front third of the vagina
  • A point in the area of ​​the anterior cervical vault, fornix cervicalis anterior ("anterior fornix zone", abbreviated to "AFE zone")

The stimulation of this connective tissue space leads to vasoconstriction and pleasant erotic sensations and sometimes female ejaculation .

Gynecological and surgical importance

The vesicovaginale septum is exposed and ruffled as part of interventional therapy to correct a Descensus uteri or Descensus vaginae (see also pelvic floor ).
