Que sont les déchirures périnéales ?<end_of_turn>
<start_of_turn>model
Your perineum is the area between your vaginal opening and back passage (anus).It is common for the perineum to tear to some extent during childbirth. Tears can also occur inside the vagina or other parts of the vulva, including the labia.

Up to 9 in every 10 first time mothers who have a vaginal birth will experience some sort of tear, graze or episiotomy. It is slightly less common for mothers who have had a vaginal birth before.

What are the types of perineal tear?
✔️First-degree
Small tears affecting only the skin which usually heal quickly and without treatment.

✔️Second-degree
Tears affecting the muscle of the perineum and the skin. These usually require stitches.

✔️Third- and fourth-degree tears
For some women (3.5 out of 100) the tear may be deeper. Third- or fourth- degree tears, also known as obstetric anal sphincter injuries (OASI), extend into the muscle that controls the anus (anal sphincter). These deeper tears need repair in an operating theatre.<end_of_turn><eos>
