Pilonidal Sinus Surgery in Ireland — Costs, Waiting Times & EU Options
Pilonidal sinus surgery treats a small tunnel in the skin at the top of the buttock crease that can repeatedly become infected. Operations range from minimally invasive techniques to excision with flap repair, and are usually done as a day case.
What is a Pilonidal Sinus Surgery?
A pilonidal sinus is a small channel in the skin of the buttock crease, often containing hair. It’s most common in young adults, particularly men. It can cause painful abscesses and persistent discharge.
Surgery removes the sinus and the tracks under the skin. Options include minimally invasive pit-picking or endoscopic treatment (EPSiT), excision with the wound left open to heal, or excision with an off-midline flap closure, which reduces the chance of the sinus coming back.
Who needs this surgery?
Surgery may be recommended for:
- Recurrent pilonidal abscesses
- A sinus that keeps discharging
- Pain and swelling at the top of the buttocks that keeps coming back
An acute abscess may first need draining, with definitive surgery later.
How the procedure works
Assessment
Your surgeon examines the area to plan the most suitable operation.
Anaesthesia
Usually a general anaesthetic; small procedures can be done under local.
Removing the sinus
The sinus and its tracks are removed or cleaned out.
Closing the wound
The wound may be closed with a flap, left partly open, or packed to heal from the base.
Home
Most people go home the same day.
Where can you have a Pilonidal Sinus Surgery?
Compare the public system, private hospitals in Ireland, and HSE-reimbursed treatment in the EU.
Public (HSE)
Free at the point of care with a GP or consultant referral. Waiting times vary widely by hospital, region and clinical urgency; your hospital or the NTPF (ntpf.ie) can tell you where you are on the list.
Private in Ireland
Ask the hospital for a fixed-price quote covering the hospital fee, consultant and anaesthetist fees. Check your health insurance plan for cover, excesses and any approved-hospital list before booking.
EU Cross-Border
Can usually be arranged under the EU Cross-Border Healthcare Directive with a referral from your GP or consultant. As this is normally a day case, prior authorisation is not usually needed, but confirm with the HSE National Contact Point before you book. You pay upfront and claim back up to the Irish public cost.
Check if you're eligibleHave your surgery in weeks, not years
Under the EU Cross-Border Healthcare Directive, you can be treated in an accredited EU/EEA hospital and claim the cost back from the HSE — with a GP or consultant referral.
Check whether you qualify and what you'd get back.
*Reimbursement is capped at the cost of the same treatment in the Irish public health system. Travel, accommodation and any balance above the HSE rate are not covered. Pre-authorisation applies to treatment involving an overnight hospital stay.
Recovering from a Pilonidal Sinus Surgery
Discomfort when sitting is common. Keep the area clean and dry.
Closed wounds heal faster; open wounds need regular dressing changes by a nurse.
Open wounds can take several weeks to heal fully. Avoid sport until healed.
Keeping the area hair-free may help prevent recurrence.
Risks and considerations
Possible risks include:
- Wound infection
- Slow wound healing or the wound opening
- The sinus coming back
- Scarring
- Numbness around the scar
Pilonidal Sinus Surgery — your questions answered
Will my pilonidal sinus come back after surgery?
It can. Off-midline flap closure and minimally invasive techniques can reduce recurrence compared with a midline closure.
How long will I be off work?
Often one to three weeks after closed or minimally invasive procedures; longer after open healing.
Will I be able to sit after surgery?
Sitting may be uncomfortable for a week or two. Cushions can help.
Can I have pilonidal sinus surgery abroad?
Yes, provided it is a treatment the HSE would provide in Ireland, you have a referral, and it is carried out in a public or private healthcare provider in another EU/EEA country. You pay upfront and claim back up to the Irish public cost. Travel and accommodation are not covered.
