Invited Commentary

The chapters contained in this section on the perineal body and posterior vagina during vaginal birth show the great progress that has been made in understanding birth-related injury. This section focuses on the full spectrum, from management of anal sphincter injury and the recognition and repair of acute trauma to the mechanism of injury by which this trauma arises, and, finally, to the important area of injury prevention. The pioneering work by Mr Sultan during the 1990s, utilizing recently developed techniques of endoanal ultrasound to reveal previously unsuspected anal sphincter injury, has led to tremendous improvements in our care of obstetric patients.
