Perineal tear degrees explained

How recovery typically progresses

Immediately after

First days

In the first couple of weeks, expect the most tenderness regardless of degree, though a third or fourth degree repair generally involves more structures and gets closer follow-up. Ice in the first 24 hours, sitz baths, and a stool softener are standard across all degrees.

Settling in

Early weeks

Around the 6-week mark, aftercare guidance for any degree still advises waiting until then for tampons, intercourse, or activity that could reopen the site. This is also when a provider typically checks how a third or fourth degree repair is settling in.

Longer arc

Beyond six weeks

Months later, first and second degree tears have usually stopped being a daily concern. Third and fourth degree tears warrant continued attention to bowel control and pelvic floor symptoms, since those structures were directly involved, and any new or ongoing symptoms are worth raising rather than assuming they are permanent.

What does the evidence show for perineal tear degrees explained?

• Perineal tears are classified into four degrees. First degree involves only the vaginal mucosa or perineal skin, second degree extends into the perineal body, third degree involves part or all of the anal sphincter and is subdivided into 3A, 3B, and 3C by how much of the external sphincter is affected, and fourth degree extends through the anal sphincter into the rectal mucosa. 1
• Third and fourth degree tears, called obstetric anal sphincter injuries, affect about 4% to 11% of vaginal deliveries in the United States. Most vaginal deliveries involve some degree of perineal trauma, and 60% to 70% of first and second degree tears are closed with sutures. 1
• Standard aftercare, ice in the first 24 hours, sitz baths several times a day after that, stool softeners, and acetaminophen or ibuprofen, applies across tear degrees, and the guidance advises waiting a full 6 weeks before tampons, intercourse, or activity that could reopen the site. 2
• A surgical cut made straight down the middle of the perineum is more prone to extending toward the rectum during delivery than an angled cut to the side, and a cut or a spontaneous tear can extend further as the baby is born, which is part of why the final degree is not always the one first expected. 3
• A perineal wound infection can develop at any tear degree, most often appearing 4 to 7 days after delivery with redness, warmth, pain, or drainage at the site, and pain that feels far worse than the wound looks on exam is a specific warning sign for a rare, more serious deep tissue infection. 4

Perineal tear degrees at a glance

When should I call my provider about perineal tear degrees explained?

Increasing pain, redness, warmth, swelling, or drainage at the site, especially appearing 4 to 7 days after delivery, are signs of a possible wound infection and need a same-day call to your provider. Pain that feels far worse than the area looks on exam is a specific warning sign for a rare but serious deep tissue infection and needs urgent evaluation. A fever, a wound that appears to be opening back up, or new loss of bowel or gas control after a third or fourth degree repair also warrant prompt medical attention rather than waiting for a scheduled postpartum visit. When in doubt, call your obstetric team the same day. Early input almost always beats waiting, and the on-call line exists exactly for this.
