A three-dimensional model of the pelvic floor and anorectal anatomy

The large number of individuals suffering from anorectal dysfunctions necessitates a better understanding of the anatomy and physiology of that region. A three-dimensional model which realistically simulates the pelvic floor and anorectal region was commissioned to supplement traditional forms of instruction for medical students and residents. This paper discusses the need for and development of a life-sized and anatomically accurate prototype model appropriate for teaching and research.
