An episiotomy is an incision in the perineum (the area between the vagina and the anus) made just before the time of birth in order to enlarge the vaginal opening and prevent spontaneous tearing. The incision is stitched closed under local anesthesia after the baby has been delivered.
The number of American mothers getting episiotomies has decreased from 64 percent to 39 percent in the last 20 years. But many experts say the current figures are still too high.
