Important Medical Notice: Surgical treatment for hidradenitis suppurativa must be planned after medical examination. A rapidly growing abscess, fever, spreading redness, severe pain or fever needs urgent assessment. Do not try to drain or cut HS lesions yourself.
Quick Answer
Surgical treatment for hidradenitis suppurativa may be considered when HS causes recurrent abscesses, chronic drainage, or established tunnels and scarring. Surgery is not the first option for every patient. Depending on the stage and lesion type, procedures may include incision and drainage, deroofing, local excision, or wide excision. The goal is to remove or open diseased tissue and reduce recurrent drainage and abscess formation. However, hidradenitis suppurativa is chronic, so medical treatment, lifestyle changes, wound care, and follow-up may still be needed after surgery.

Hidradenitis suppurativa, also known as HS or acne inversa, is a chronic inflammatory disease of the hair follicles. It commonly affects friction-prone areas such as the armpits, groin, buttocks, under-breast area, inner thighs, and perianal region. The ICD-10-CM code for hidradenitis suppurativa is L73.2.L73.2.
Surgery is considered when HS becomes structurally established in the skin. This means that the problem is no longer only a short-term inflamed lump. Instead, there may be chronic sinus tracts, tunnels, scarred tissue, recurrent abscesses, or persistent drainage that no longer responds to medication alone.
Not every patient with HS needs surgery. Mild disease may be managed with lifestyle measures, topical treatment, oral medications, antibiotics, biologic therapies, or laser-based approaches. Surgery becomes more relevant when there is a specific diseased area that keeps recurring, draining, or scarring despite medical treatment.
️ Clinical Note: In HS, the decision for surgery is not based only on the size of one abscess. The key questions are: Does it keep coming back? Is there a tunnel? Is there scarred diseased tissue? Does drainage keep returning despite treatment?
For a general overview of HS, see What is Hidradenitis Suppurativa? Diagnosis and Treatment Process.
There are several surgical and procedural options for hidradenitis suppurativa. The best method depends on disease stage, lesion depth, tunnel formation, location, recurrence pattern, and patient health. A tiny urgent abscess and a wide scarred tunnel network are very different creatures; they should not be treated with the same net.
Procedure | When It May Be Used | Main Goal |
|---|---|---|
Incision and drainage | Tense, painful acute abscess | Short-term relief of pressure and pain |
Deroofing | Persistent tunnels or localized recurrent lesions | Open the tunnel roof and allow healing from the base |
Limited excision | Localized chronic diseased tissue | Remove a defined HS area |
Wide excision | Advanced, scarred, recurrent, or extensive disease | Remove broad diseased tissue down to healthy margins |
CO2 laser excision / ablation | Selected chronic HS lesions or tissue-sparing treatment plans | Precisely remove or vaporize diseased tissue |
Flap or graft reconstruction | Large defects after wide excision | Close or reconstruct larger surgical wounds |
Incision and drainage relieves an acute abscess quickly. Deroofing and excision are more targeted toward persistent tunnels and recurrent sites. Wide excision may be considered in advanced disease, especially Hurley Stage II or III disease with chronic tracts and scarring.
The right procedure is chosen after clinical examination. The physician evaluates the body area, number of lesions, depth of disease, presence of sinus tracts, scarring, drainage, and the patient's overall health.
️ Important Warning: A drained abscess may feel better, but drainage alone does not remove the tunnel underneath. If the tunnel remains, the problem usually returns. This is why proper staging and examination are essential before choosing treatment.

Before surgery, the goal is to understand the full disease pattern and optimize wound healing. HS surgery is not only a cutting decision; it is a planning decision. The body area, active infection status, patient habits, and wound care capacity all matter.
Some procedures are better performed when severe acute inflammation has settled. In other cases, urgent abscess drainage cannot wait. The timing depends on whether the problem is an acute abscess, chronic tunnel, active infection, or scarred recurrent disease.
If lifestyle or supportive care is part of the plan, see our lifestyle and diet guide. How to Treat Hidradenitis Suppurativa Naturally? and Could Diet Affect Hidradenitis Suppurativa?.
The surgical process depends on the procedure. Some minor procedures may be performed under local anesthesia, while larger operations may require regional or general anesthesia. The surgical plan should be explained clearly before the procedure, including anesthesia type and expected recovery.
Incision and drainage: The abscess is opened and the pus is evacuated. It may reduce pain quickly, but it does not treat the underlying tunnels.
Deroofing is a tissue-sparing technique used for tunnels and persistent localized HS lesions. The “roof” of the tunnel is removed, while the base is left to heal from the bottom upward. It may be useful for selected localized disease and can sometimes be performed in-office under local anesthesia.
Excision removes diseased skin and underlying affected tissue. A limited excision targets a smaller defined area. A wide excision removes a larger region of diseased tissue and may be used in advanced or recurrent HS. The wound may be left to heal open, closed directly, or reconstructed with a flap or graft depending on size and location.
CO2 laser may be used in selected cases to remove or vaporize diseased HS tissue with precision. It may be considered as part of a tissue-directed plan, especially for chronic localized lesions. Suitability depends on disease activity, location, and availability of the technique for the individual patient.
️ Clinical Note: The best HS operation is not always the biggest one. In some patients, a focused deroofing can be enough. In others, wide excision is needed. The art is matching the tool to the tunnel, not swinging the largest hammer at every shadow.
After HS surgery, wound care is a major part of treatment. Healing time depends on the procedure, wound size, body area, closure method, smoking status, diabetes, infection control, and dressing routine.
Wound Type | How It Heals | Important Point |
|---|---|---|
Open wound | Heals gradually from the base upward | Requires regular dressing and patience |
Primary closure | Wound edges are stitched together | Tension, infection, and wound separation must be monitored |
Flap or graft | Tissue is moved or grafted to cover a larger defect | Blood supply, smoking, and pressure are critical factors |
Patients should follow their surgeon’s wound care instructions closely. If drainage, redness or fever develops, contact your surgeon promptly.
Yes. Hidradenitis suppurativa may recur after surgery. Recurrence can occur in the operated area or in a different HS-prone body area. Surgery can remove or open diseased tissue, but it does not erase the patient’s underlying inflammatory tendency.
The goal after surgery is long-term disease control. This may include lifestyle measures, medical treatment, laser hair reduction, and regular follow-up. Patients should not think of surgery as the final page of the book; for many HS patients, it is a new chapter in a longer management plan.
Incorrect actions before or after HS surgery can increase pain, infection risk, and recurrence. The following mistakes should be avoided.
Emergency Warning: After HS surgery, fever, chills, rapidly spreading redness, severe worsening pain, or foul-smelling discharge from the wound requires urgent medical review.
Some discomfort, mild drainage, and redness can be normal in the first days after surgery. However, certain signs — fever, spreading redness, severe worsening pain, or foul-smelling discharge — need prompt medical review.
Early communication with the care team can prevent small wound issues from becoming larger surgical problems.
If you have recurrent HS abscesses, chronic drainage or non-healing tunnels, a surgical consultation will clarify your options.
