  • Title: Anatomy of the bulbus vestibuli: A cadaveric study.
    Author: Ostrzenski A.
    Journal: Ann Anat; 2021 Jan; 233():151588. PubMed ID: 32889108.
    Abstract:
    BACKGROUND: To describe the BV anatomy in detail, to compare previous BV descriptions and illustrations to the current study's findings and photograms, to show the BV topographic relation of the BV to the urethral meatus, to document the BV anatomy using photograms. METHODS: Ten fresh human female adult cadavers were used. Stratum-by-stratum anatomical dissections in sagittal, transverse, and coronal planes were performed. The BV was dissected-off from the original location of the posterior-distal vaginal wall and the anterior anal wall. RESULTS: The BV was located within the posterior-distal vagina and composed of two vertical legs, which fused to one another. The inferior pars intermedia fused both descending legs to the anterior-proximal perineal urethral wall, and BV embraced the anterior-proximal urethra. The superior pars intermedia connects the BV to the posterior-distal clitoral body. The BV legs traversed parallel to and aside from the vaginal introitus and the lateral urethra and not crossing the anterior-distal urethra. The tile-end was a tapered end which terminates in the vicinity of Bartholin glands. Laterally, the BV legs outspread to the medial labia minora and attach to the ischiopubic ramus. The anatomical site-specific defect (s) occurs within the BV. CONCLUSIONS: The present study resolves the BV anatomical controversy and shows that the BV runs parallel to and aside from the anterior-distal urethra and the BV. The site-specific defect(s) can occur within the BV. This study provides important information for anatomy educators and surgeons.
