Surgical Treatment for Hidradenitis Suppurativa
Surgical Treatment for Hidradenitis Suppurativa: When and How Is It Performed?
💡 Quick Answer
Surgical treatment for hidradenitis suppurativa may be considered when HS causes recurrent abscesses, chronic drainage, painful tunnels under the skin, scarred diseased tissue, or symptoms that do not respond well to medical treatment. Surgery is not the first option for every patient. Depending on the stage and lesion type, procedures may include incision and drainage for urgent abscess relief, deroofing for persistent tunnels, limited excision for localized disease, wide excision for advanced HS, CO2 laser-based tissue removal, or reconstruction with flaps or grafts. The goal is to remove or open diseased tissue, reduce recurrent drainage, improve pain, and support long-term control. However, hidradenitis suppurativa is chronic, so medical treatment, lifestyle changes, wound care, and follow-up may still be needed after surgery.

When is Surgery Considered for Hidradenitis Suppurativa?
Hidradenitis suppurativa, also known as HS or acne inversa, is a chronic inflammatory disease of the hair follicle. 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.
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 does not fully respond 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 forming tunnels.
For a general overview of HS, see What is Hidradenitis Suppurativa? Diagnosis and Treatment Process.
Which Surgical Methods Are Used?
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.
Main Surgical and Procedural Options
| 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 may provide fast relief in an acute abscess, but it does not remove chronic HS tissue. 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.
How is the Right Procedure Chosen?
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, previous treatments, pain level, and the patient’s general health.
Factors That Influence Surgical Planning
- Hurley stage of HS
- Number and location of lesions
- Presence of sinus tracts or tunnels
- Amount and duration of drainage
- Severity of pain
- Previous antibiotic or biologic treatment response
- Previous surgery and recurrence history
- Smoking status
- Diabetes, immune suppression, or wound healing problems
- Need for reconstruction, flap, or graft

What Happens Before Surgery?
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.
Preoperative Evaluation May Include
- Physical examination of active and scarred areas
- Assessment of drainage, odor, and inflammation
- Mapping of tunnels or recurrent sites
- Review of current medications
- Review of previous antibiotics, biologics, or procedures
- Evaluation of smoking, diabetes, and wound healing risk
- Discussion of anesthesia type
- Planning of wound closure or open healing
- Explanation of recovery time and dressing needs
Why Timing Matters
Some procedures are better performed when severe acute inflammation has settled. In other cases, urgent abscess drainage may be needed immediately to relieve pain and infection risk. The timing depends on whether the problem is an acute abscess, chronic tunnel, active infection, or scarred recurrent disease.

How is HS Surgery Performed?
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 to the patient before the procedure.
Incision and Drainage
Incision and drainage is used mainly for a tense, painful abscess. The aim is to release pressure and drain pus. It may reduce pain quickly, but it often does not prevent recurrence because the underlying HS structure may remain.
Deroofing
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.
Limited or Wide Excision
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-Based Treatment
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 available expertise.
What Happens After Surgery?
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.
Postoperative Care May Include
- Regular wound dressing
- Pain control as recommended by the physician
- Keeping the area clean and protected
- Avoiding friction and tight clothing
- Monitoring drainage amount and odor
- Watching for fever or spreading redness
- Follow-up appointments
- Planning return to work, exercise, and daily activity
Open Healing vs Closed Wound
| 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 becomes foul-smelling, pain increases instead of improving, or fever develops, medical evaluation is required.
Can HS Come Back After Surgery?
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.
Factors That May Influence Recurrence
- Disease severity before surgery
- Presence of multiple affected areas
- Incomplete removal of diseased tissue
- Ongoing smoking
- Excess weight and friction
- Poor wound care or missed follow-up
- Persistent inflammation in nearby tissue
- Lack of long-term medical management
The goal after surgery is long-term disease control. This may include lifestyle measures, medical treatment, laser hair reduction in selected areas, wound care, and 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.
What Should Not Be Done?
Incorrect actions before or after HS surgery can increase pain, infection risk, recurrence, and wound healing problems. The following mistakes should be avoided.
- Do not squeeze, puncture, or cut abscesses at home.
- Do not apply vinegar, garlic, lemon, alcohol, or harsh essential oils to open wounds.
- Do not stop prescribed wound care early without medical advice.
- Do not smoke during wound healing if avoidable; seek cessation support.
- Do not wear tight clothing that rubs the surgical area.
- Do not ignore foul-smelling drainage or spreading redness.
- Do not assume antibiotics alone can remove chronic tunnels.
- Do not skip follow-up because the wound “looks better”.
When Should You Contact a Doctor Urgently?
Some discomfort, mild drainage, and tenderness may occur after surgery. However, certain symptoms are not routine and should not be watched casually from the sofa like a slow weather forecast.
Contact a Doctor If You Notice:
- Fever or chills
- Increasing pain after initial improvement
- Foul-smelling or heavy drainage
- Spreading redness or warmth
- Wound edges opening
- Bleeding that does not stop
- New painful swelling near the surgical area
- Allergic reaction to medication or dressing material
- Difficulty walking, sitting, or moving the affected area
Early communication with the care team can prevent small wound issues from becoming larger surgical problems.
Frequently Asked Questions About Surgical Treatment for Hidradenitis Suppurativa
When is surgery needed for hidradenitis suppurativa?
Surgery may be needed when hidradenitis suppurativa causes recurrent abscesses, chronic drainage, sinus tracts, scarred diseased tissue, or symptoms that do not respond well to medication. It is more commonly considered in persistent localized disease or advanced Hurley Stage II and III disease. However, surgery is not necessary for every HS patient. The decision depends on disease stage, lesion location, pain, drainage, previous treatment response, and quality-of-life impact.
Is incision and drainage a cure for HS?
No. Incision and drainage may relieve pressure and pain from a tense acute abscess, but it usually does not cure hidradenitis suppurativa. The underlying inflammatory disease, sinus tracts, and scarred tissue may remain. Therefore, recurrence after drainage is possible. Drainage is mainly an urgent relief procedure, while long-term HS control may require medication, laser treatment, deroofing, excision, lifestyle changes, or combined care.
What is deroofing in hidradenitis suppurativa?
Deroofing is a tissue-sparing procedure used for persistent HS tunnels or localized recurrent lesions. During deroofing, the roof of the sinus tract is removed, and the base of the tunnel is left to heal from the bottom upward. It may be useful in selected patients with localized disease. Compared with wide excision, deroofing may preserve more tissue, but it is not suitable for every case, especially extensive or highly advanced disease.
What is wide excision for HS?
Wide excision is a surgical procedure that removes a larger area of diseased HS tissue, often including scarred skin and underlying affected tissue. It may be considered in advanced, recurrent, or extensive disease with chronic drainage and tunnels. After wide excision, the wound may be left open to heal, closed directly, or reconstructed with a flap or graft. Recovery time depends on the size, location, closure method, and patient factors such as smoking, diabetes, and wound care quality.
Can CO2 laser be used for hidradenitis suppurativa surgery?
CO2 laser may be used in selected hidradenitis suppurativa cases to remove or vaporize diseased tissue with precision. It may be considered for chronic localized lesions or as part of a tissue-directed surgical plan. However, CO2 laser is not appropriate for every patient. Active infection, abscess pressure, disease extent, location, previous treatments, and available expertise must be evaluated before planning laser-based treatment.
Does HS come back after surgery?
Yes, hidradenitis suppurativa can recur after surgery. Recurrence may occur in the operated area or in another HS-prone body region. The risk depends on disease severity, surgical method, whether all diseased tissue was treated, smoking, weight, friction, wound care, and long-term follow-up. Surgery can help remove chronic diseased tissue, but HS is a chronic inflammatory condition, so ongoing medical management and lifestyle support may still be needed.
How long does recovery take after HS surgery?
Recovery time depends on the type of procedure, wound size, body area, closure method, and patient health. Small procedures may heal faster, while wide excision or open wound healing may take weeks or longer. Areas exposed to movement, sweating, sitting, or friction may require more careful care. Smoking, diabetes, infection, and poor nutrition can delay healing. Your surgeon should provide a personalized recovery and dressing plan.
Are antibiotics needed after HS surgery?
Antibiotics may be used before or after HS surgery in selected patients, especially if there is active infection, cellulitis, heavy drainage, or a high risk of infection. However, antibiotics are not automatically required for every surgical case. The decision depends on the wound, procedure type, patient risk factors, and the physician’s judgment. Antibiotics should not be started or repeated without medical advice.
When should I call a doctor after HS surgery?
You should contact a doctor if you develop fever, chills, increasing pain, spreading redness, heavy or foul-smelling drainage, wound opening, bleeding that does not stop, blackened tissue, or new painful swelling near the surgical area. Mild discomfort and limited drainage may occur, but worsening symptoms should not be ignored. Early evaluation can help prevent infection, wound separation, or delayed healing.
5 Key Takeaways
- Surgery may be considered for recurrent abscesses, chronic drainage, sinus tracts, scarred tissue, or advanced HS.
- Incision and drainage can relieve acute abscess pressure but usually does not cure HS.
- Deroofing, limited excision, wide excision, CO2 laser, flap, or graft reconstruction may be considered depending on disease pattern.
- HS can recur after surgery, so long-term follow-up and supportive medical care remain important.
- Wound care, smoking cessation, friction reduction, and follow-up appointments are essential for recovery.
Appointment and Surgical Evaluation
If you have recurrent HS abscesses, chronic drainage, tunnels, scarring, pain, or symptoms that return despite medication, a surgical evaluation can help determine whether drainage, deroofing, excision, laser-based treatment, or combined care is appropriate.
