Perineal tear
Your perineum is the area between your vagina and anus (back passage or bottom). Many women tear their perineum during childbirth.
- First-degree tears are small tears of just the skin and don't usually need stitches.
- Second-degree tears are deeper and affect the muscle as well as the skin and need stitches to be repaired.
- Third-degree tears involve tearing of the vaginal wall and the anal sphincter (the muscle that controls the back passage).
- Fourth-degree tears extend to the lining of the back passage, or anus.
Causes of perineal tears
Often there's no clear reason for tearing. There's an increased risk for women who:
- have their first vaginal birth
- have a long pushing phase of their labour (over two hours)
- need a forceps or ventouse (suction) birth
- have a large baby
- have the baby's shoulder stuck behind their pubic bone (shoulder dystocia)
- had labour induced.
Preventing perineal tears
This information explains how to massage your perineum in the weeks leading up to your delivery to reduce the risk of it tearing.
