Pdf Summary

The presentation by Dr. Marlene Corton at the Urogynecology Webinar on September 20, 2023, focuses on the detailed anatomy of the vulvar and perineal regions and their clinical implications, particularly in obstetric and gynecologic contexts. Dr. Corton emphasizes the importance of understanding the anatomy of the clitoris, associated vulvar structures, the perineal body, and the anal sphincter complex. This knowledge is essential for effective clinical application during various medical procedures, injury prevention, and management of complications.<br /><br />Key anatomical structures discussed include the external female genitalia, anterior and posterior perineal triangles, vestibule, and Bartholin glands. Dr. Corton describes various spaces within the anterior perineal triangle, such as the membranous layer, perineal membrane, and the contents of the superficial space, including the body of the clitoris, vestibular bulb, and Bartholin gland. The course and branches of nerves, such as the pudendal nerve and the dorsal nerve of the clitoris, are explained, highlighting their relevance in surgical procedures.<br /><br />Clinical applications are demonstrated through scenarios including Bartholin gland excision with associated risk of bleeding, and potential nerve injury leading to loss of clitoral sensation. These examples underscore the necessity for clinicians to have an in-depth anatomical understanding to avoid complications such as significant bleeding or nerve damage.<br /><br />Furthermore, Dr. Corton covers the anatomy and function of the perineal body and anal sphincter complex, including the contribution of muscles like bulbospongiosus, transverse perineal, and the anal sphincters (EAS and IAS). The intricate details about the sphincter complex's structure and nerve supply, particularly via the pudendal nerve, are crucial for managing conditions like fecal incontinence and pelvic floor disorders.<br /><br />In summary, Dr. Corton concludes that comprehensive anatomical knowledge is fundamental not only for injury prevention but also for the evaluation and management of complications in urogynecology.
