Understanding Perineal Tears and Stiches

 

-By Bushra Hatahet, UK-Trained Clinical Midwife

During a vaginal birth, the tissues between the vagina and anus (the perineum) stretch significantly to allow your baby to be born.

Many women experience some degree of tearing, while others have no tears at all.

Although the thought of tearing can sound worrying, most tears heal very well with appropriate care.

What is the perineum?

The perineum is the area between:

  • The vaginal opening
  • The anus

During birth, this tissue stretches to allow your baby’s head and shoulders to pass.

Some women remain completely intact, while others experience a small graze or a deeper tear.

Intact Perineum

An intact perineum means:

  • No tear
  • No stitches required
  • Recovery is often quicker
  • Mild swelling and tenderness may still occur

Even without a tear, it is normal for the area to feel bruised for a few days.

Grazes (Skin Tears)

A graze is a very small superficial injury involving only the skin.

These often:

  • Do not bleed significantly
  • May not require stitches
  • Usually heal naturally within a few weeks

Your midwife or doctor will decide whether stitches are needed.

First-Degree Tear

A first-degree tear involves:

  • Skin of the perineum only

It is the mildest true tear.

Some first-degree tears require stitches, while others heal well without them.

Healing is usually quick with minimal long-term problems.

Second-Degree Tear

A second-degree tear extends into:

  • Skin
  • Perineal muscles

These muscles support the pelvic floor and help control the vaginal opening.

Most second-degree tears require stitches.

This is the most common type of tear after a vaginal birth.

With appropriate repair, most women make an excellent recovery.

Third-Degree Tear

A third-degree tear extends further into the muscles that control the anus (the anal sphincter).

This type of injury requires specialist repair.

Third-degree tears are divided into:

3a

Less than 50% of the external anal sphincter is torn.

3b

More than 50% of the external anal sphincter is torn.

3c

Both the external and internal anal sphincter muscles are torn.

Because these muscles are responsible for bowel control, careful repair is extremely important.

Fourth-Degree Tear

A fourth-degree tear is the most severe type of obstetric tear.

It extends through:

  • Perineal muscles
  • External anal sphincter
  • Internal anal sphincter
  • Lining of the rectum (anal mucosa)

Although uncommon, these tears can usually be repaired successfully by an experienced obstetrician.

Other Tears That May Occur

Not all tears occur in the perineum.

Labial Tears

Small tears involving the labia.

These may or may not require stitches depending on:

  • Bleeding
  • Size
  • Position

Vaginal Tears

These occur inside the vagina.

Some are small and heal naturally.

Others require stitches to stop bleeding and encourage healing.

Clitoral Tears

These are uncommon but can occur because the tissues around the clitoris are highly vascular.

Small tears often heal well.

Your doctor will decide whether stitches are required.

Urethral Tears

These occur around the opening where urine passes.

Depending on the location and bleeding, they may or may not require repair.

Some women may temporarily require a urinary catheter while swelling settles.

Pain Relief During Stitching

Your comfort is extremely important.

Before repairing any tear, your healthcare team will ensure you have adequate pain relief.

Depending on your birth and the type of tear, this may include:

Epidural

If your epidural is already working well, it can often be topped up to provide excellent pain relief during the repair.

Local Anaesthetic

For smaller tears, local anaesthetic is injected into the area before stitching.

This numbs the tissues so you should feel pressure but not pain.

Entonox (Gas and Air)

Gas and air can also be used alongside local anaesthetic to help you feel more comfortable and relaxed.

Spinal Anaesthetic

If you require repair in theatre and do not already have an epidural, a spinal anaesthetic may be recommended.

This provides complete numbness from the waist down during the procedure.

Why are Third- and Fourth-Degree Tears Repaired in Theatre?

Third- and fourth-degree tears are repaired in an operating theatre rather than the birth room.

This provides:

  • Excellent pain relief
  • A sterile operating environment
  • Optimal lighting
  • Better positioning
  • Careful assessment of the anal sphincter
  • Direct visualisation of the anal mucosa (rectal lining)
  • The opportunity for repair by an appropriately trained obstetrician

These factors help achieve the best possible repair and reduce the risk of future complications.

After Your Repair

Following your repair, your healthcare team will discuss your recovery plan with you.

This may include:

Antibiotics

Women with third- and fourth-degree tears are routinely offered antibiotics to reduce the risk of infection.

Pain Relief

Regular pain relief helps you move comfortably and care for your baby.

Do not wait until the pain becomes severe before taking medication.

Stool Softeners

Laxatives or stool softeners are routinely prescribed after third- and fourth-degree tears.

These help prevent constipation and reduce strain on the repair while it heals.

Diet

To promote healing and comfortable bowel movements:

  • Drink plenty of fluids
  • Eat a high-fibre diet
  • Include fruit, vegetables and wholegrains
  • Avoid becoming constipated

Pelvic Floor Physiotherapy

Women who sustain third- or fourth-degree tears should be referred to a Women’s Health Physiotherapist.

Physiotherapy can help with:

  • Pelvic floor recovery
  • Muscle strength
  • Bladder control
  • Bowel control
  • Returning to exercise safely

Many women find this an important part of their recovery.

Follow-Up Clinic

Women with third- and fourth-degree tears are usually reviewed in a specialist follow-up clinic approximately 6–12 weeks after birth.

At your appointment, your healthcare professional may discuss:

  • Healing
  • Pain
  • Bladder function
  • Bowel control
  • Pelvic floor function
  • Future pregnancies and birth options
  • Whether any additional treatment or investigations are needed

Please tell your healthcare provider if you experience ongoing pain, leakage of stool or wind, or concerns about your recovery.

Looking After Your Stitches

While your stitches heal:

  • Keep the area clean using warm water.
  • Pat dry gently after washing.
  • Change maternity pads regularly.
  • Wear loose, breathable underwear.
  • Avoid constipation.
  • Continue pelvic floor exercises once advised.

• • Contact your healthcare provider if you notice increasing pain, offensive-smelling discharge, fever, or your wound appears to be opening.

Episiotomy

An episiotomy is a surgical cut made in the perineum to enlarge the vaginal opening.

It is not performed routinely but may be recommended if:

  • Your baby needs to be born quickly.
  • Forceps are being used.
  • Your healthcare professional believes it may reduce severe tearing in certain situations.

An episiotomy is performed using local anaesthetic (or an existing epidural/spinal) and is repaired with dissolvable stitches after birth.

Recovery is very similar to that of a second-degree tear.

Key Points to Remember

  • Most women experience either no tear or a first- or second-degree tear.
  • Third- and fourth-degree tears are less common but usually heal well following specialist repair.
  • Your comfort during stitching is a priority, and effective pain relief will always be provided.
  • Women with obstetric anal sphincter injuries receive additional follow-up, physiotherapy and support to optimise recovery.
