Cochlear implant mapping - London
A private pathway for adults and children with severe to profound sensorineural hearing loss: full pre-implant assessment, day-case surgery, switch-on and lifetime mapping with Cochlear, MED-EL or Advanced Bionics devices.
What it is
Bypassing damaged hair cells to restore useful hearing.
A cochlear implant has two halves: an internal electrode array surgically placed in the cochlea, and an external speech processor worn behind or off the ear.
Cochlear implantation is the surgical placement of a multi-channel electrode array into the scala tympani of the cochlea, connected to a receiver-stimulator under the scalp. The external speech processor picks up sound, converts it to a coded electrical signal and transmits it across the skin to the receiver, which stimulates the cochlear nerve directly.
Because it bypasses damaged hair cells, an implant can restore functional hearing where hearing aids can no longer help, in severe to profound sensorineural loss. It is not a cure and it does not restore normal hearing; with rehabilitation, most adults regain useful speech understanding and many use the phone again.
Indications
Who a cochlear implant is for.
Candidacy has widened. NICE TA566 now covers severe-to-profound bilateral loss and single-sided deafness where hearing aids give limited benefit.
-
Bilateral severe to profound loss
Bilateral severe-to-profound sensorineural hearing loss with limited benefit from optimally fitted hearing aids.
-
Single-sided deafness
Recent NICE TA566 expansion permits implantation for single-sided deafness where a hearing aid is not effective.
-
Post-lingual adults
Adults who lost hearing after developing speech typically adapt most quickly to the electric signal.
-
Congenital hearing loss in children
Early implantation, ideally before 12 months of age where safe, gives the best speech and language outcomes.
Device brands
Cochlear, MED-EL, Advanced Bionics.
Outcomes across the three UK-approved manufacturers are broadly similar. Brand choice is driven by MRI compatibility, connectivity and patient preference.
-
Cochlear Nucleus 8, Kanso 2
Widely used behind-the-ear and off-the-ear processors. Strong smartphone streaming and remote mapping support.
-
MED-EL Sonnet 3, Rondo 3
Long electrode arrays for full cochlear coverage. Popular where hearing preservation is a priority.
-
Advanced Bionics Naida CI M
Advanced sound processing and Phonak hearing-aid pairing for asymmetric or bimodal listeners.
Assessment
A multi-disciplinary work-up before any decision.
Every candidate is seen across audiology, imaging, ENT and neurotology, speech and language therapy, psychology and medical review.
- 01
Audiology
Unaided and aided pure-tone audiometry plus speech testing in quiet and noise with best-fit hearing aids.
- 02
Imaging
MRI of the internal auditory meatus and high-resolution CT of the temporal bone to map cochlear anatomy and rule out obstruction.
- 03
ENT and neurotology
Consultant review of aetiology, middle-ear status, vestibular function and surgical candidacy.
- 04
Speech and language therapy
Baseline communication assessment and planning for auditory-verbal rehabilitation after switch-on.
- 05
Psychology and medical
Realistic expectations, motivation, and fitness for general anaesthetic are confirmed before booking surgery.
Surgery, switch-on and mapping
From theatre to a lifetime of programming.
Surgery is only the beginning. The mapping schedule and the rehabilitation that sits alongside it are what turn the electrode array into useful hearing.
- 01
Surgery
Day case or one night in hospital under general anaesthetic. Two to three hours. Mastoidectomy and posterior tympanotomy give access to the round window; the electrode array is threaded into the scala tympani of the cochlea.
- 02
Switch-on and initial mapping
Three to four weeks after surgery to allow healing. The audiologist sets threshold (T) and comfort (C) levels on each electrode, so speech is audible but never uncomfortable.
- 03
Early mapping schedule
Four to six weekly mapping sessions in the first three months as the auditory system settles and your tolerance for stimulation increases.
- 04
Ongoing mapping
Six-monthly review through the first year, then annual mapping and processor checks for the life of the implant.
- 05
Rehabilitation
Structured auditory-verbal therapy with a specialist SLT. Sound quality is initially electronic and improves over six to twelve months as the brain adapts.
Rehabilitation
The brain does most of the work.
Structured auditory-verbal therapy with a specialist speech and language therapist is what converts electrical stimulation into useful speech understanding.
Sound at switch-on is often described as robotic, tinny or like Donald Duck. Over the first six to twelve months, as the brain relearns to interpret the coded signal, most post-lingually deafened adults report that sound becomes progressively more natural and speech understanding improves in quiet and then in noise.
Wearing the processor during every waking hour, doing daily listening practice and attending scheduled therapy sessions matters more to outcome than which brand of implant you choose.
Cost
What a private cochlear implant costs.
Indicative UK-private ranges for adult unilateral implantation. Bilateral and paediatric packages are quoted separately.
| Item | Indicative range | Typical duration | Turnaround |
|---|---|---|---|
| Cochlear implant, all-inclusive (implant + surgery + processor + first-year mapping) | £45,000 to £65,000 | 2 to 3 hours | 1 night |
| Pre-implant multi-disciplinary assessment | £1,800 to £3,200 | 2 to 3 visits | 2 to 4 weeks |
| Annual mapping and processor maintenance | £850 to £1,600 | 60 min | Same visit |
| Replacement speech processor (out of warranty) | £7,500 to £10,500 | 45 min | Same visit |
Prices vary with the centre, the surgeon, and whether the package bundles processor upgrades and rehabilitation. We come back with a firm quote from two or three centres within one working day.

Frequently asked
Everything patients ask about cochlear implants.
On cost, NHS access, switch-on, mapping, timelines and brand choice.
-
How much does a private cochlear implant cost in the UK?
All-inclusive private packages in London typically range from £45,000 to £65,000, covering the implant device, surgery, speech processor and the first year of mapping and rehabilitation. Annual maintenance thereafter is around £850 to £1,600.
-
Is cochlear implantation available on the NHS?
Yes. Specialist NHS Auditory Implant Programme centres implant adults and children who meet NICE TA566 criteria, including single-sided deafness in some cases. It is free at the point of use, though waiting times and centre choice differ from the private pathway.
-
How long after surgery is switch-on?
Three to four weeks. This allows the surgical site to heal and swelling to settle so the initial mapping accurately reflects your response to stimulation.
-
What does mapping actually involve?
The audiologist connects your speech processor to a computer and, one electrode at a time, sets the softest level you can just detect (T level) and the loudest level that is still comfortable (C level). Programmes are then written to the processor for daily use.
-
How quickly will I understand speech?
Most post-lingually deafened adults hear environmental sounds on day one and begin to understand familiar speech within weeks. Sound quality is initially electronic and typically becomes more natural over six to twelve months, provided you commit to rehabilitation.
-
Which brand should I choose - Cochlear, MED-EL or Advanced Bionics?
Outcomes across the three main brands are broadly similar. Brand choice is usually driven by MRI compatibility, connectivity with your phone and hearing aid, electrode length, and personal preference for the sound processor.
