Not all childbirth-related complications are widely understood or openly discussed. One such condition is perineal tears. It is a type of injury that affects the area between the vagina and the rectum, commonly occurring during vaginal delivery.

A perineal tear can range in severity from minor skin involvement to deeper tissue damage and is classified into four grades. Sometimes, a surgical intervention known as an episiotomy can be performed to create a controlled opening and assist with the delivery process. Keep reading to learn about its types, causes, and treatment to improve care and recovery for the mother.

What are Perineal Tears?

Perineal tears are injuries to the area between the vagina and anus that commonly occur during vaginal childbirth. They can range from mild skin tears to deeper tissue damage. 

A perineal tear or vaginal tear is a type of injury that may occur during birth. Also referred to as a perineal laceration, it involves a tear in the tissues surrounding the vagina and the perineum. The perineal region, commonly called the perineum, is the area located between the vaginal opening and the anus.

During a vaginal birth, the skin around the vagina naturally thickens and becomes more flexible. This process helps the baby’s head and body pass through more easily. Despite this natural adaptation, tearing is quite common. In fact, up to 90% of women who have a vaginal delivery experience some degree of tearing.

However, several factors can increase the likelihood of a vaginal tear. These include:

• A larger-than-average baby
• An early birth that does not give the skin time to stretch adequately
• The use of instruments such as forceps during delivery

What are the Various Types of Perineal Tears?

Perineal tears are classified into 4 degrees: first-degree (minor skin tear), second-degree (involves skin and muscles), third-degree (extends to the anal sphincter), and fourth-degree (reaches the rectum).

Vaginal tears can be categorised into 4 grades according to severity. The size of the tear defines its type. Here are the various types of vaginal tears:

1. First-degree Tear: This is the mildest form of tearing. It only infects the external skin around the vagina and perineum and is usually self-healing and does not require stitches.
2. Second-degree Tear: This is the most frequently occurring type. The tear goes deeper, affecting both the skin and the underlying muscles of the vagina and perineum. Stitches are usually required for proper healing.
3. Third-degree Tear: This type of tear extends further, reaching from the vaginal area to the anus. It involves damage not only to the skin and perineal muscles but also to the anal sphincter muscles, which control bowel movements. Stitches are necessary for recovery.
4. Fourth-degree Tear: This is the most severe and least common form of tearing during childbirth. It extends from the vagina through the perineum, affecting the anal sphincter muscles and reaching into the rectum.

In such cases, the healthcare provider may need to perform the repair in an operating room instead of the delivery room.

What are the Causes of Perineal Tears?

Perineal tears can be caused by childbirth, sexual intercourse, shaving, waxing, vaginal dryness, and other conditions that make the skin weak and vulnerable to any type of injury. Other factors that cause perineal tears include having a large baby, quick labour, vaginal birth for the first time, or decreased skin elasticity.

Most of the cuts or tears in the vagina are commonly linked to activities such as sexual intercourse, shaving, or waxing. However, there are many other cases in which someone ends up developing a tear in and around the vagina, including pre-existing skin problems or giving birth.

Here are the primary causes involved:

• Sexual Intercourse

Sexual intercourse is one of the common reasons why some women develop perineal tears. Lack of proper vaginal lubrication might lead to such an injury. Intense sexual activity and using sex toys might also contribute to tearing the vaginal area.

• Shaving and Waxing Pubic Hair

Shaving and waxing pubic hair are also common factors that result in cuts on the vulva. According to research conducted in 2017, about 25.6% of those who groomed their pubic hair sustained cuts, most of which were vulvar cuts in women. In some cases, these injuries required medical treatment, such as antibiotics or even minor surgery.

• Childbirth

About 80% of women experience perineal tearing during childbirth. A perineal tear refers to damage to the skin or muscles of the perineum, which is located between the vagina and the anus. In some cases, the tear could affect the vagina and even the anal sphincter that controls bowel movements.

Women who are giving birth for the first time are generally at a higher risk of experiencing perineal tears compared to those who have previously had a vaginal delivery.

• Skin Conditions

Certain skin conditions can make the vaginal or vulvar area more prone to cuts and irritation. These include:

• Eczema is a skin condition characterised by red, inflamed, and itchy skin. Symptoms of eczema include fluid exudation, crusting, and itching in the vagina and vulva.
• Lichen Planus is an inflammatory disease that causes itchiness, burning, or a feeling of raw skin in the vulva. If the disease affects the vagina, there will be yellowish sticky discharges and tissue destruction.
• Psoriasis, a common skin condition that is characterised by itchy and dry scales. However, in the vulvar region, Psoriasis manifests as smooth, pink spots with well-defined edges.
• Lichen Sclerosus, an inflammatory skin disease that primarily affects the genitalia. The affected skin is easily torn or develops fissures.
• Vulvovaginal atrophy (atrophic vaginitis), a condition that causes the vaginal tissues to become thinner, drier, and less elastic, making tears more likely.
• Vaginal scarring or tissue damage, which may result from prior surgeries or radiation treatments in the pelvic region.
• Vulvovaginitis, commonly caused by Candida albicans (also known as thrush), may irritate the tissues and predispose them to cuts.
• Genital herpes (herpes simplex infection), which may develop clusters of fluid-filled blisters that may rupture and leave tiny open sores that look like cuts.

• Other Causes

Other factors that may contribute to the formation of vaginal or vulvar cuts include:

• Foreign body insertion into the vagina
• Tampon insertion or extraction errors
• Vaginal dryness
• Vaginismus
• Thinning of the vaginal tissue due to age
• Steroid medication usage

What are the Symptoms of Perineal Tears?

The perineal tear symptoms typically involve pain, burning, swelling, tenderness and discomfort in the vaginal or perineal region, particularly during sitting, walking or during urination. In more serious instances, one might experience bowel or bladder control problems, emotional distress, and pain that impact daily activities and postpartum recovery.

In case of a perineal tear, a variety of symptoms can occur that disrupt everyday comfort and normal activities. It is essential to identify these symptoms to obtain the necessary treatment and aid recovery in a timely manner.

Physical symptoms may include:

• Perineal pain or discomfort immediately after the tear, which is usually sharp, burning, or tender, particularly during motions or during use of the toilet.
• Inability to sit, stand, or walk comfortably, which may cause problems in performing routine tasks or taking care of a newborn.
• Bladder or bowel changes, including difficulty urinating or urgency, especially with more severe tears.

Emotional and functional effects may include:

• Feelings of anxiety related to healing or concerns about resuming intimacy
• Difficulty managing daily activities, including maintaining hygiene or caring for a baby
• Uncertainty about which physical activities are safe during the recovery phase

How are Perineal Tears Diagnosed?

Perineal tears are determined by a careful physical examination whereby the medical practitioner examines the vaginal and perineal tissues to determine the extent of the injury. Reviewing the patient’s symptoms and medical history also helps identify whether the tear is new, recurring, or associated with other underlying conditions.

A healthcare provider usually conducts a physical examination and analyses your medical history to diagnose a vaginal or vulvar cut. This procedure helps them understand your symptoms and identify any underlying conditions or contributing factors that might have caused the injury.

They can also question you about the symptoms, whether they are new or recurrent, to find out whether you have had a history of similar problems. When the cuts are tiny or barely visible, the provider may use a colposcope, a specialised instrument with a bright light, to closely examine and magnify the affected area during the assessment.

Diagnostic Tests

In most situations, additional tests are not necessary to diagnose or manage vaginal or vulvar cuts, especially when the cause is clear and the injury appears minor without signs of infection.

In contrast, tests may be necessary when it is critical to establish whether there are any underlying conditions that might contribute to the injury. Tests that might be required include:

• Culture: A sample of vaginal discharge is collected by swab and brought to the lab to determine infections such as bacterial vaginosis, yeast infections, or sexually transmitted diseases.
• Biopsy: A small tissue sample is collected from the tear site for microscopic evaluation to determine the underlying causes of repetitive or persistent tears of the vagina.

What is a Perineal Tear Treated?

Perineal tears are treated based on their severity: mild tears usually heal on their own, whereas moderate to severe tears are treated with dissolvable stitches to repair the damaged tissue. Recovery is supported by pain-relief methods, proper hygiene, hydration, stool softeners, and cooling pads to reduce discomfort and promote faster healing.

The strategy for dealing with a vaginal or perineal tear varies according to the severity of the tear. First-degree tears do not require stitches because they can heal on their own. Second-, third-, and fourth-degree tears require stitches to repair the injured tissues and ensure proper healing.

Dissolvable sutures are used to sew these tears, and the stitches dissolve on their own after six weeks. In the case of the anal sphincter, the medical practitioner may opt for a more complex repair using dissolvable sutures. Some discomfort is expected as the tear heals.

There are some measures that you can take to ease the discomfort and promote rapid healing of the tear:

• Thoroughly cleanse the area after going to the bathroom.
• Pat the area dry gently using toilet paper without rubbing or wiping.
• Maintain adequate hydration to prevent constipation, and, if necessary, use stool softeners.
• To avoid any pain or irritation of the tear, healthcare providers can advise using cooling pads and sanitary pads after delivery.

FAQs about Perineal Tears

1. How long does it take for a vaginal tear to heal?

Most women begin to notice relief from the discomfort caused by a vaginal tear within about two weeks. If stitches are required, they generally dissolve on their own within approximately six weeks.

In most cases, there is no need for a follow-up visit to remove stitches or for additional treatment, as healing occurs naturally.

2. Can a woman have a vaginal delivery in a second pregnancy if she had a vaginal tear previously?

In most situations, having a tear during a previous delivery does not mean it will happen again in future childbirths. Small tears normally heal well, and they do not disrupt subsequent vaginal births.

However, if a woman has experienced a third- or fourth-degree tear before, there may be a slightly increased risk of tearing in subsequent vaginal births.

3. When should I start pelvic floor physical therapy after experiencing a perineal tear?

Individuals may recover at an individual rate, but most people can start gentle pelvic floor therapy at 6 to 8 weeks after delivery, provided that their healthcare provider approves it.

It can also be helpful to schedule an earlier consultation to discuss recovery strategies and receive guidance on the healing process.

4. What can I do to prepare my perineum for childbirth and potentially minimise tearing?

Preparation can typically start during the third trimester. Techniques such as perineal massage, specific strengthening exercises, and learning optimal birthing positions may help reduce the likelihood of tearing.

A trained professional can guide you through safe and effective, evidence-based methods tailored to your body’s needs.

5. Will scar tissue from perineal tearing cause long-term problems?

Scar tissue is a normal part of the body’s healing process. With appropriate care, including physical therapy, it is usually possible to maintain flexibility and prevent tightness or discomfort, ensuring normal function over time.

6. What are the risks of untreated severe perineal tears?

Unless properly treated, third- or fourth-degree tears can lead to complications like infection, persistent pain, urinary or faecal incontinence, and discomfort during sex. Immediate treatment and correct follow-up are important in the prevention of chronic complications.

7. How can I manage pain after a perineal tear?

A combination of prescribed drugs, cold compresses or cooling pads, and proper hygiene can be used to manage pain. A sitz bath can also be helpful. Strain should be avoided when passing stool, loose-fitting garments should be used, and sufficient rest should be taken to aid healing.

8. When is it safe to resume sexual activity after a perineal tear?

The majority of healthcare practitioners recommend waiting until the tear has completely healed before engaging in sexual activity, which is about six weeks following childbirth.

However, this timeline may vary depending on the severity of the tear and individual recovery, so it is best to consult your doctor before restarting sexual activity.

9. Can perineal tears affect future pregnancies or deliveries?

In general, minor tears do not have any significant impact on future pregnancies or childbirth. Nevertheless, females with more severe tears (third and fourth degrees) might be at an increased risk during subsequent births.

Depending on your medical history, your healthcare provider will assist in identifying the safest delivery option.

10. Are there any warning signs of infection during healing?

Yes, some symptoms can indicate an infection. These include pain, swelling, redness, abnormal or foul-smelling discharge, fever, or delayed recovery. If any of these signs appear, it is important to seek medical attention promptly to avoid further complications.

Conclusion

Perineal tears are a common childbirth condition that usually heals in a few weeks under good care. While most cases recover completely within 6 weeks of delivery, the severity can vary depending on the degree of the tear. Seeking guidance from a healthcare expert ensures better healing and reduces the risk of complications.
