Cochlear Implant & Mastoid Surgery in Ireland — Costs, Waiting Times & EU Options
A cochlear implant is an electronic device that gives a sense of sound to people with severe or profound hearing loss, while mastoid surgery removes infection or a cholesteatoma from the bone behind the ear. Both are specialist operations done under general anaesthetic.
What is a Cochlear Implant & Mastoid Surgery?
A cochlear implant bypasses the damaged inner ear and stimulates the hearing nerve directly. It has an internal part placed under the skin behind the ear, with a thin electrode threaded into the cochlea, and an external sound processor worn on the ear. In Ireland, implants are provided through the National Cochlear Implant Programme.
Mastoid surgery (mastoidectomy) removes diseased bone and skin from the mastoid, the honeycomb bone behind the ear. It is most often done to remove a cholesteatoma, an abnormal growth of skin in the middle ear that can slowly damage the hearing bones and surrounding structures if left untreated.
Who needs this surgery?
These procedures are considered for:
- Severe to profound hearing loss in both ears where hearing aids no longer help enough (cochlear implant)
- Children born with profound deafness, ideally implanted early
- Cholesteatoma or chronic ear infection that doesn’t settle with treatment (mastoid surgery)
- Complications of chronic ear disease, such as persistent discharge or erosion of the hearing bones
How the procedure works
Specialist assessment
Cochlear implant candidacy involves hearing tests, scans and counselling by a specialist team. Mastoid surgery is planned using a CT scan.
General anaesthetic
You'll be asleep throughout, and the facial nerve is monitored during surgery.
The operation
An incision behind the ear gives access to the mastoid bone, where the surgeon removes disease or places the implant electrode into the cochlea.
Closing and dressing
The wound is closed and a head dressing applied. Most patients stay one or two nights.
Switch-on or follow-up
A cochlear implant is switched on a few weeks later, followed by months of tuning and hearing rehabilitation.
Where can you have a Cochlear Implant & Mastoid 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
Eligible under the EU Cross-Border Healthcare Directive with a referral. Because it involves an overnight hospital stay, you need prior authorisation from the HSE before travelling. You pay upfront and claim back up to the Irish public cost, minus the public inpatient charge where it applies. Cochlear implants depend on years of programming and rehabilitation, so discuss any plan to be implanted abroad with the National Cochlear Implant Programme first.
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 Cochlear Implant & Mastoid Surgery
Some pain, dizziness and a feeling of fullness are common. Keep the wound dry.
The wound heals and most people return to normal activities. Avoid contact sport and flying until cleared by your surgeon.
Cochlear implants are activated around two to four weeks after surgery. Sound may seem unnatural at first.
Hearing with an implant improves with practice and regular tuning. After mastoid surgery, regular checks look for any return of cholesteatoma.
Risks and considerations
Ear surgery near delicate structures carries specific risks:
- Dizziness or balance problems, usually temporary
- Tinnitus or change in taste
- Facial nerve weakness, which is rare
- Loss of any remaining natural hearing in the operated ear
- Cholesteatoma returning, which may need further surgery; device failure after implantation is rare
Cochlear Implant & Mastoid Surgery — your questions answered
Who is suitable for a cochlear implant?
Adults and children with severe to profound hearing loss who get limited benefit from hearing aids. A specialist team assesses suitability.
Does a cochlear implant restore normal hearing?
No. It provides a different kind of sound that most people learn to understand well over time, especially with rehabilitation.
What happens if a cholesteatoma isn't treated?
It can slowly erode the hearing bones and nearby structures, causing hearing loss, dizziness and, rarely, serious infection, so surgery is usually recommended.
Can I have a cochlear implant abroad?
Cochlear implants in Ireland are provided through the national programme, and long-term programming and support are a key part of treatment, so discuss any plan to go abroad with your ENT team first. Mastoid surgery abroad requires prior authorisation.
