The vulval vestibule (or vulvar vestibule) is a part of the vulva between the labia minora into which the urethral opening and the vaginal opening open. Its edge is marked by Hart's line. It represents lower end of urogenital sinus from stage of embryo.
The external urethral orifice (orificium urethræ externum; urinary meatus) is placed about 2.5 cm behind the glans clitoridis and immediately in front of that of the vagina; it usually assumes the form of a short, sagittal cleft with slightly raised margins. Nearby are the openings of the Skene's ducts.
The vaginal orifice is a median slit below and behind the opening of the urethra; its size varies inversely with that of the hymen.
The prevalence of pain at the vulvar vestibule is relatively common. A study by the University of Michigan found that about 28% of women have experienced vulvar vestibular pain in the past, and about 8% had the pain in the last 6 months.
