the pelvic floor and associated structures occupying the pelvic outlet, bounded anteriorly by the pubic symphysis, laterally by the ischial tuberosities, and posteriorly by the coccyx. During childbirth the perineum may be torn, resulting in possible damage to the urinary meatus and anal sphincter. To avoid a perineal tear, the obstetrician often cuts the perineum just before delivery and sutures the incision after delivery of the infant and the placenta. This procedure is called an episiotomy. Surgical repair of an episiotomy or of a torn or lacerated perineum is called perineorrhaphy.
