Indicative pricing

What private pilonidal surgery costs in the UK.

Indicative ranges across our partner day-surgery units.

In short

£2,500–£4,500, home the same day.

Procedure Indicative range
Incision and drainage of pilonidal abscess £1,500–£3,000
EPSiT (endoscopic pilonidal sinus treatment) £2,500–£4,500
Excision, laid open (healing by packing) £2,500–£4,800
Excision with primary closure £3,000–£5,500
Karydakis or Bascom cleft-lift flap £3,500–£6,500
Revision surgery for recurrent disease £4,000–£7,500
Colorectal consultation only £200–£350

Prices vary by hospital, by surgeon and by technique - flap procedures and revision surgery sit at the top of the range, and laid-open wounds add dressing costs over the healing weeks.

The problem

The right technique, a realistic wound plan, and recurrence taken seriously.

Pilonidal surgery is where one-size-fits-all quietly fails - the same midline excision for every patient, wound care left vague, prevention never mentioned. We fix all three before you consent.

  • Match the operation to the disease

    Limited first-time disease suits EPSiT or laser; extensive or recurrent disease deserves an off-midline flap. The technique should never depend on habit.

  • Know the wound before you choose it

    Laid-open means weeks of packing; closure means watching for breakdown. We make sure the daily reality of each option is understood in advance.

  • Prevention is half the cure

    Hair control after healing measurably cuts recurrence. A hair-removal plan belongs in the aftercare, not as an afterthought.

When it helps

When pilonidal surgery is the right step.

The situations we see most, plus the one red flag that means urgent drainage rather than a routine booking.

  • Recurrent pilonidal abscesses

    A painful, swollen collection at the top of the natal cleft that keeps returning - each abscess makes definitive surgery more sensible.

  • A chronically discharging sinus

    A midline pit that leaks fluid, blood or pus onto underwear week after week - the classic chronic pilonidal picture.

  • Pain on sitting and driving

    Discomfort with every car journey, desk day or gym session - the symptom that finally brings most people to surgery.

  • Multiple pits and branching tracks

    More extensive disease with several midline pits and lateral openings - the pattern that shapes which operation is right.

  • Recurrence after previous surgery

    Disease that has come back after excision. Revision usually means an off-midline flap technique with better odds.

  • A quiet sinus found incidentally

    An asymptomatic pit needs no operation at all - hair removal and vigilance are enough. We say so when that is the honest answer.

  • Occupational pressure

    Drivers, cyclists, soldiers and desk-bound workers whose disease flares with prolonged sitting - timing surgery around work matters and we plan for it.

  • Red flag: spreading redness, fever or severe pain

    A hot, rapidly enlarging swelling with fever means an acute abscess that needs draining within days - same-week urgent care, not a routine surgical booking.

Procedure options

Technique depends on the extent of the disease.

What each option involves - from emergency drainage and keyhole EPSiT to formal excision and the off-midline flap procedures with the lowest recurrence.

  • Incision and drainage

    The emergency operation for an acute abscess - pus released under anaesthetic. It relieves the crisis but does not cure the sinus; definitive surgery is usually planned once things settle.

  • EPSiT (endoscopic treatment)

    A camera passed through the pit; hair and infected tissue cleared and the track cauterised from inside. Minimal wound, fastest recovery, no cutting of the cleft - recurrence slightly higher than flaps.

  • Excision, laid open

    The sinus network cut out and the wound left open to heal from the base with regular packing. Low recurrence, but 6–12 weeks of dressings - the trade-off explained honestly.

  • Excision with primary closure

    The sinus excised and the wound stitched closed. Quicker healing than laid-open, but midline closure carries higher recurrence - off-midline techniques are usually preferred.

  • Karydakis flap

    An off-midline excision and flap that flattens the natal cleft - addressing the anatomy that caused the disease. Strong evidence for lower recurrence in recurrent or extensive disease.

  • Bascom cleft-lift

    A tissue-preserving off-midline repair that lifts and closes the cleft. Especially useful for recurrent disease and unhealed midline wounds.

  • Fibrin glue and pit-picking

    Minor-procedure options for limited disease - pits trimmed and tracks sealed. Quick and low-impact; best suited to early, simple sinuses.

  • Laser ablation (SiLaC)

    The track destroyed with a radial laser fibre through the pit. Day-case, small wound, encouraging results - availability varies across the network.

Safety and recovery

What to expect afterwards - honestly.

Pilonidal surgery is safe day-case work. The things worth planning are the wound, the weeks of sitting carefully, and the hair-control routine that keeps the disease from returning.

  • A day-case operation for nearly everyone

    General or spinal anaesthetic, home the same day in almost all cases. Flap procedures occasionally stay one night.

  • Wound problems are the main nuisance

    The natal cleft is a hard place to heal. Wound breakdown after primary closure and slow healing after laid-open excision are the most common issues - not dangerous, but tedious.

  • Infection and bleeding

    Wound infection occurs in a minority and responds to antibiotics and dressing care. Significant bleeding is uncommon; a little oozing onto dressings early on is normal.

  • Recurrence is the number that matters

    Roughly 5–15 percent of pilonidal disease recurs depending on technique and disease extent - lowest with off-midline flaps, higher with midline closure. Choose the operation accordingly.

  • Pain and sitting

    Expect soreness on sitting for one to three weeks. A soft cushion, regular simple analgesia and short frequent walks make the difference. Avoid prolonged sitting early on.

  • Time off work

    EPSiT and laser: often 3–7 days. Excision with closure or flap: 1–3 weeks. Laid-open excision: work is possible once dressings are manageable, but full healing takes 6–12 weeks.

  • Hair control prevents recurrence

    Loose hair drilling into the cleft is the disease mechanism. Regular hair removal - razor, cream or laser epilation - after healing is the best-evidenced prevention. We build it into the plan.

  • Driving and exercise

    Drive when you can sit comfortably and perform an emergency stop - usually within days after EPSiT, 1–2 weeks after excision. Swimming waits for a fully healed wound; gym work returns gradually.

  • Red flags after surgery

    Fever, spreading redness, a wound that becomes markedly more painful, or persistent fresh bleeding needs the same-day team or A&E, not a routine call.

Reading your operation note

Your operation note in four parts. Read the last one first.

Whichever technique was used - EPSiT, excision or flap - the note the surgeon sends you keeps to the same shape.

    Indication, technique and anaesthetic

    Why the operation was done, which technique was used - drainage, EPSiT, excision, flap - and the anaesthetic given.

  2. 02 Technique

    Disease extent and wound management

    What was found - pits, tracks, cavities, lateral extensions - what was removed or ablated, and whether the wound was closed, flapped or laid open.

Pilonidal sinus surgery is usually covered when medically indicated - recurrent abscesses or a chronically discharging sinus qualify readily.

Frequently asked

Everything we get asked about pilonidal surgery.

Quick answers on causes, technique choice, recovery, cost and recurrence.

  • What is a pilonidal sinus and what causes it?

    A pilonidal sinus is a small tunnel under the skin at the top of the buttock crease, almost always caused by loose hairs drilling into the skin and triggering inflammation and infection. It mostly affects people in their late teens to thirties, and sitting for long periods, a deep natal cleft, coarse body hair and friction all raise the risk. It is common, benign and very treatable.

  • Does a pilonidal sinus always need surgery?

    No. A sinus that causes no symptoms needs no operation - hair removal and keeping the area clean are enough. Surgery is for sinuses that repeatedly form abscesses, discharge chronically or make sitting painful. An acute abscess needs prompt drainage first; the definitive operation is then planned once the inflammation settles.

  • Which pilonidal operation is best?

    It depends on the disease. Limited, first-time disease suits minimally invasive options - EPSiT, laser, pit-picking - with small wounds and fast recovery. Extensive or recurrent disease does better with off-midline flap techniques such as the Karydakis or Bascom cleft-lift, which flatten the cleft and carry the lowest recurrence rates.

  • How long is recovery after pilonidal sinus surgery?

    EPSiT or laser: back to desk work in about 3–7 days, with the small wound healed in 2–4 weeks. Excision with closure or a flap: 1–3 weeks off work, healed by about 4–6 weeks. Laid-open excision heals from the base with regular packing over 6–12 weeks - slower, but with reliably low recurrence. Sitting is sore for the first one to three weeks whichever route is taken.

  • How much does private pilonidal sinus surgery cost in the UK?

    Indicatively: abscess drainage £1,500–£3,000, EPSiT £2,500–£4,500, excision £2,500–£5,500 depending on closure, and Karydakis or cleft-lift flaps £3,500–£6,500. Revision surgery for recurrent disease runs £4,000–£7,500.

  • Will my pilonidal sinus come back after surgery?

    It can - recurrence runs at roughly 5–15 percent overall, lowest after off-midline flap procedures and highest after simple midline closure. The other half of prevention is hair control: keeping the healed cleft free of hair with regular shaving, depilatory cream or laser epilation measurably cuts recurrence. Your surgeon builds this into the aftercare plan, and recurrent disease still has good surgical options.
