Hidradenitis Surgery: Deroofing and Excision

Hidradenitis surgery removes or opens selected diseased areas to help troublesome tunnels and recurring lesions heal.

Hidradenitis suppurativa can create inflamed nodules, drainage and tunnels beneath the skin. Surgery is aimed at a particular persistent area, rather than treating every possible future flare. Deroofing opens the roof of a tunnel so it can heal from the base. Excision removes a wider block of affected skin and tissue when disease is more extensive.

Recovery depends on the body site, the size of the treated area and whether the wound is closed or left open to heal. Dressings may need regular changes, and drainage or tenderness can occur while new tissue forms. Movement can be uncomfortable when treatment is in a skin fold, so work, exercise and lifting plans may need adjusting.

Your surgical team should show you how to clean the area, which dressing to use, how to manage pain, and when to return for wound checks. Contact the team promptly for worsening redness, swelling, fever, unexpected bleeding, a bad smell, or pain that is escalating rather than settling.

Possible problems include bleeding, infection, delayed healing, wound separation, scarring, altered skin sensation and discomfort. Surgery in areas exposed to friction, moisture or repeated movement can require particularly careful wound care. The chance of a problem cannot be given as one fixed figure: it varies with the procedure, wound size, location, smoking status, other health conditions and how active the hidradenitis is.

Before treatment, ask the surgeon which complications are most relevant to your planned procedure and what symptoms should trigger same-day contact. This makes the discussion specific to your skin, rather than relying on a general estimate.

A well-selected operation can help a treated tunnel or repeatedly inflamed area heal, but hidradenitis suppurativa is a long-term inflammatory condition. Activity can continue in nearby skin or develop in a different region. Results also differ between deroofing and a wider excision because they address different patterns of disease.

The most useful goal-setting conversation is about the specific area: whether it has a tunnel, how often it drains, what operation is proposed, and how the wound will be managed. Ongoing medical treatment may still be recommended to control inflammation outside the surgical site.

Surgery is usually planned after examining the affected skin and discussing whether a local procedure or a more extensive operation fits the pattern of disease. The closure plan matters because a stitched wound, a skin graft and an open wound each have different aftercare needs.

Surgery may be considered for a recurring lesion that keeps draining, a persistent tunnel, scarring that traps inflammation, or a local area that has not responded adequately to non-surgical care. It is not automatically the right next step for every flare. A dermatologist and surgeon can assess the location, extent of scarring, current inflammation and your ability to manage wound care.

The visit begins with confirming the target area and discussing anaesthesia, medicines, allergies and practical support for recovery. During the procedure, the surgeon opens or removes the planned tissue. The wound is then closed, covered with a graft, or dressed for gradual healing. You leave with written wound-care instructions and a follow-up plan.

Healing is a process rather than a single deadline. Some people need short-term help with dressing changes or tasks that rub the surgical area. Keep follow-up appointments even if the wound seems to be progressing well, because the team can adjust dressings and assess healing. Do not soak, apply unadvised products or resume strenuous activity until your clinician says the wound is ready.

Tell the team about medicines that affect bleeding, nicotine use, diabetes, immune-suppressing treatment, prior wound-healing problems and any reaction to anaesthesia. Follow the pre-operative instructions closely. After surgery, protect the area from friction where possible and seek clinical advice early if the wound changes in a concerning way.

Depending on the lesion and stage of hidradenitis, options may include topical or oral medicines, anti-inflammatory treatment, drainage for an acute painful collection, dressings, and measures that reduce irritation in the area. These approaches can also be used around the time of surgery. The appropriate choice depends on whether the main issue is active inflammation, a tunnel, scarring or a mixture of these.

Look for a dermatologist or surgeon experienced in hidradenitis procedures and wound planning. Bring a list of past treatments, current medicines and the areas that flare or drain. Ask who will handle dressing advice between appointments and how to contact the service if you are worried after surgery.
