The episiotomy procedure was first described in 1742; it subsequently gained widespread acceptance, peaking in the 1920s. Its reported benefits included preservation of the integrity of the pelvic floor and prevention of uterine prolapse and other vaginal trauma. Since the 1920s, the number of women who receive an episiotomy during their delivery has steadily declined. In modern obstetrics, episiotomy is not routinely performed. However, in certain circumstances and when performed by a skilled physician, episiotomy may be beneficial.
