HS Surgery: What Patients Need to Know

Surgery can be life-changing for HS patients with established sinus tracts and scarring. This guide explains every surgical option, who is a candidate, what to expect, and how to prepare.

When Is Surgery Needed?

Surgery is not the first line of treatment for HS, but for many patients with moderate-to-severe disease, it is an essential part of comprehensive care. Medical therapy, antibiotics, biologics, hormonal treatments , manages the inflammatory disease systemically, but it cannot remove established sinus tracts and scar tissue. Surgery addresses the structural consequences of HS that medication cannot reverse.

Surgery is typically considered when:

  • Established sinus tracts are present and not responding to medical therapy
  • Recurrent abscesses occur in the same location despite treatment
  • Significant scarring is causing functional impairment (restricted movement, pain)
  • Stage II or III disease with localized areas of severe involvement
  • Quality of life is severely impacted by a specific area of disease

Surgery should be performed by a surgeon experienced in HS. Outcomes are significantly better at specialized centers. Ask your dermatologist for a referral.

Types of HS Surgery

Several surgical approaches are used for HS, ranging from minimally invasive office procedures to major surgery requiring general anesthesia. The right choice depends on your disease stage, the extent of involvement, and your surgeon's expertise.

Deroofing

Recovery
2–6 weeks
Recurrence
20–30%
Best For
Limited sinus tracts, Stage II
Advantages

Fast recovery, minimal scarring, can be repeated

Limitations

Requires specialized equipment and expertise

Incision & Drainage (I&D)

Minor Procedure
Anesthesia
Local
Recovery
1–2 weeks
Recurrence
Very High (not curative)
Best For
Acute abscess, temporary relief only
Advantages

Immediate pain relief

Limitations

Not curative; high recurrence; does not address sinus tracts

Choosing the Right Procedure

The right surgical approach depends on your Hurley stage, the number and location of affected areas, your overall health, and your surgeon's experience. Use the following framework as a starting point for your conversation with your dermatologist or surgeon.

Hurley Stage I

Medical therapy first. If a single recurrent abscess does not respond, deroofing or CO2 laser is appropriate. Surgery is rarely the first choice at this stage.

Hurley Stage II

Deroofing is the preferred option for limited sinus tracts. Wide local excision (WLE) is considered when multiple tracts are clustered in one region. CO2 laser is an alternative where available.

Hurley Stage III

Wide local excision is the standard of care for extensive, confluent disease. Skin grafting or flap reconstruction may be required. Surgery should be combined with biologic therapy to prevent recurrence in adjacent areas.

Acute Abscess (any stage)

Incision and drainage provides temporary relief but is not curative. It is appropriate for managing an acute painful abscess while awaiting definitive surgical planning.

Important: These are general guidelines. Your surgeon will make the final recommendation based on your individual anatomy, disease extent, and goals. Always seek a second opinion for major surgery.

Before Surgery: Preparation

Medical Preparation

  • Discuss biologic therapy timing with your surgeon (some require pausing before surgery)
  • Optimize nutrition, protein and zinc support wound healing
  • Quit smoking if possible , smoking significantly impairs wound healing
  • Manage blood sugar if diabetic
  • Discuss all medications including supplements

Practical Preparation

  • Arrange transportation home (you cannot drive after general anesthesia)
  • Prepare your recovery space at home before the procedure
  • Stock up on wound care supplies
  • Plan for time off work, be realistic about recovery duration
  • Arrange help with daily tasks for the first 1–2 weeks

Recovery Timeline

Recovery from HS surgery varies significantly by procedure type. Here is a general timeline for wide local excision, the most common major HS surgery:

Days 1–3
Acute Recovery

Pain management is the priority. Take prescribed pain medication on schedule. Rest as much as possible. Keep the wound elevated if possible. Do not change dressings unless instructed.

Week 1–2
Early Healing

Pain decreases significantly. Begin wound care as instructed by your surgeon. Light activity only. Watch for signs of infection: increasing redness, warmth, swelling, fever, or unusual odor.

Weeks 2–6
Active Healing

Wound granulation and epithelialization. Continue wound care. Gradually increase activity as tolerated. Attend follow-up appointments. Scar tissue begins forming.

Months 2–6
Scar Maturation

Scar tissue matures and softens. Begin scar management (silicone gel, massage) once wound is fully closed. Resume normal activities. Resume biologic therapy if paused.

For detailed post-operative wound care, see our HS Surgery Recovery page.

Post-Op Wound Care

Proper wound care after HS surgery is critical for healing and reducing the risk of infection. Your surgeon will provide specific instructions, but the following principles apply to most HS surgical wounds.

Dressing Changes

  • Change dressings as instructed, typically once or twice daily
  • Use non-adherent dressings to prevent trauma on removal
  • Rinse wound gently with saline or clean water before re-dressing
  • Pat dry, never rub
  • Keep a wound care log to track healing progress

Signs of Infection

  • Increasing redness or warmth spreading beyond the wound edge
  • Swelling that worsens after the first 48 hours
  • Fever above 38 degrees C (100.4 degrees F)
  • Unusual or foul-smelling discharge
  • Wound edges separating (dehiscence)

Promoting Healing

  • High-protein diet supports tissue repair (aim for 1.2-1.5g/kg body weight)
  • Zinc and vitamin C supplementation may support wound healing
  • Stay hydrated
  • Avoid smoking, it significantly impairs blood flow and healing
  • Keep wound out of direct sunlight until fully healed

Activity Restrictions

  • Avoid submerging the wound (baths, swimming pools, hot tubs) until fully closed
  • No strenuous exercise or heavy lifting for 4-6 weeks after major surgery
  • Wear loose, breathable clothing over the wound site
  • Avoid friction or pressure on the wound area
  • Return to work timeline varies: desk work 1-2 weeks, physical work 4-8 weeks

Preventing Recurrence After Surgery

Surgery removes existing disease but does not prevent HS from developing in new areas. The most effective strategy for preventing post-surgical recurrence is continuing biologic therapy.

Post-Surgical Prevention Strategy

  • Resume biologic therapy as soon as your surgeon clears you (typically 2–4 weeks post-op)
  • Continue lifestyle modifications: diet, weight management, smoking cessation
  • Maintain regular dermatology follow-ups to monitor for new disease activity
  • Address new lesions early, early intervention prevents progression to sinus tracts
  • Consider adjuvant treatments (topical antibiotics, zinc supplements) as recommended

Frequently Asked Questions

Who is a candidate for HS surgery?
Surgery is generally considered for HS patients who have: established sinus tracts that do not respond to medical therapy, recurrent abscesses in the same location, significant scarring causing functional impairment, or Stage II–III disease with localized areas of severe involvement. Surgery is most effective when combined with ongoing biologic therapy to prevent recurrence in new areas.
What is the difference between deroofing and wide local excision?
Deroofing involves removing the roof of a sinus tract while leaving the base intact. It is a less invasive procedure with faster recovery and is best for limited sinus tracts. Wide local excision (WLE) removes all affected tissue in a region, the entire skin and subcutaneous tissue down to the fascia. WLE has lower recurrence rates but requires longer recovery and may need skin grafting.
How long is recovery from HS surgery?
Recovery time varies significantly by procedure type and location. Deroofing typically heals in 2–6 weeks. Wide local excision with primary closure heals in 4–8 weeks. WLE with skin grafting or secondary intention healing can take 3–6 months for full healing. Individual factors like disease severity, location, and overall health also affect recovery time.
Does HS come back after surgery?
Recurrence rates depend on the procedure and whether medical therapy continues post-surgery. Deroofing has recurrence rates of 20–30% at the treated site. Wide local excision has lower recurrence at the treated site (5–15%) but HS can develop in adjacent or new areas. Continuing biologic therapy after surgery significantly reduces the risk of recurrence.
Is HS surgery covered by insurance?
In most countries, HS surgery is covered by health insurance when medically necessary. In the US, coverage varies by insurer and plan. Documentation of failed medical therapy, disease severity, and functional impairment strengthens the case for coverage. Work with your dermatologist and surgeon to provide thorough documentation. Patient advocacy organizations can provide guidance on insurance appeals.
What should I ask my surgeon before HS surgery?
Key questions include: What type of surgery do you recommend and why? What is the expected recurrence rate? How long is the recovery? Will I need a skin graft? What are the risks specific to my case? How many HS surgeries have you performed? Should I continue my biologic therapy before and after surgery? What does post-operative wound care look like?
