An episiotomy is a surgical incision made to enlarge the vaginal opening just before birth. This procedure was once widely practiced, supposedly to prevent severe tears and hasten healing. However, medical understanding shifted as research suggested that a natural tear often heals better than a surgical cut, and the practice became restricted. Many women who had the procedure years ago now question whether the incision could be the source of persistent health issues experienced later in life.
Defining the Types of Episiotomy and Current Practice
The episiotomy procedure involves two main incision types, each carrying a different risk profile for long-term complications. The midline (or median) episiotomy is a vertical incision made straight down toward the anus. This approach is easier to repair but carries a significantly higher risk of extending into a third- or fourth-degree tear, potentially damaging the anal sphincter complex.
The mediolateral episiotomy extends at an angle toward the buttocks. While far less likely to involve the anal sphincter, it is associated with more initial blood loss and greater pain during recovery. It also requires a more difficult repair process.
Medical organizations now recommend a restrictive approach, performing the procedure only when medically necessary. This includes during an operative delivery or when a severe tear is imminent. The type of incision performed is a major determinant in the specific later-in-life problems a woman may face.
Long-Term Pelvic Floor Dysfunction
The primary concern regarding episiotomy involves the integrity and function of the pelvic floor muscles, the sling of muscles and connective tissue supporting the pelvic organs. Cutting and subsequent scarring of the perineal body, a central tendinous structure, can weaken the overall support system. This structural change may contribute to long-term functional problems, though data linking episiotomy directly to every pelvic floor disorder remains complex.
A major risk is the extension of the incision, particularly a midline one, resulting in an obstetric anal sphincter injury (OASIS). This injury involves the muscles controlling bowel movements, leading to a higher risk of anal incontinence years later. Failure to properly repair these higher-degree tears at delivery is a significant factor in chronic anorectal dysfunction. The presence of a severe laceration resulting from the procedure is a clear risk factor for urinary incontinence or pelvic organ prolapse.
Chronic Pain and Sexual Health Concerns
A distinct set of long-term problems stems from the surgical wound itself, manifesting as chronic pain and sexual health issues. Dyspareunia, or persistent pain with sexual intercourse, is a commonly reported concern that can last for years. This pain is frequently caused by scar tissue that has healed in a tight, rigid, or poorly flexible manner, a process known as fibrosis.
The scar tissue, especially if thick or uneven, can create intense tenderness at the entrance of the vagina. Pain may also be linked to nerve entrapment, where the healing process has compressed a nerve branch. This can lead to chronic localized pain or allodynia, where normal touch is perceived as painful. The mediolateral incision is sometimes linked to a higher risk of long-term discomfort during sexual activity due to the larger amount of tissue involved in the angled cut.
Treatment Options for Persistent Issues
There are effective strategies for managing or resolving the persistent issues that can arise years after an episiotomy. Pelvic floor physical therapy is often the first-line treatment, even for scars that are decades old. Specialized physical therapists use manual therapy techniques to mobilize and soften rigid scar tissue, reducing tightness and improving perineal flexibility.
For women experiencing chronic pain from a rigid scar, a minor surgical procedure called a revision episiotomy, or perineoplasty, may be an option. This involves surgically excising the painful scar tissue and re-suturing the area to achieve a smoother, more pliable result. For structural issues like incontinence or prolapse that are severe or unresponsive to conservative management, surgical repair is available. Topical treatments, such as creams or localized injections, may also be used to manage nerve-related pain and improve tissue quality.
