Abstract
The perineum (Fig. 1.1) is defined as the inferior outlet of the pelvis. It is a diamond-shaped area with its major axis between the pubis and the tip of the coccyx and its minor axis along the ischial tuberosity. The perineum is commonly divided into two anatomic triangles: the anterior urogenital triangle and the posterior anal triangle. The deep borders of the perineum are composed of the pubic arch, the arcuate ligament of the pubis, and, on either side, the inferior portions of the pubis and ischium.
