The cochlear implant journey: what to expect, step by step

If someone in your family has been told that a cochlear implant might help, it is natural to feel hopeful and a little overwhelmed at the same time. The good news is that the journey follows a clear path, and you do not have to walk it alone.

This guide explains each step in plain language, based on information published by MED-EL, the implant manufacturer Harmony represents as an authorised agent. It is general information, not medical advice: your ENT surgeon and implant team will guide you.

First, what is a cochlear implant?

A hearing aid makes sound louder. A cochlear implant works differently: according to MED-EL, it bypasses the damaged part of the inner ear and uses electrical signals to stimulate the hearing nerve directly. The brain then receives these signals as sound.

The system has two parts:

The audio processor, worn behind the ear or off the ear, which picks up sound through its microphones.
The implant, placed just under the skin behind the ear, which sends electrical pulses along a thin electrode array inside the cochlea.

For a refresher on the ear itself, see how hearing works.

Step 1: Who may be a candidate?

MED-EL says cochlear implants are for people with severe-to-profound sensorineural hearing loss, in both ears or in one ear (known as single-sided deafness), who get little or no benefit from hearing aids. Signs that it may be time to ask include:

hearing aids no longer seem to help
phone calls have become difficult
you or your child rely heavily on lip-reading

According to MED-EL, cochlear implants are approved for babies from six months of age (seven months in the USA), and there is no upper age limit. MED-EL notes that adults as old as 100 have received one. For children, MED-EL explains that implanting young makes success more likely, because the brain is primed for learning language.

Step 2: Assessment

The journey begins with assessments to confirm whether an implant is suitable and to check for anything else the team should consider. MED-EL describes the first step as a medical and audiological evaluation, and says this is the stage where the clinical team walks the family through what to expect next.

Use this time to ask questions, and bring a family member with you. A thorough hearing test is often the very first step, giving everyone a clear picture to work from.

Step 3: Surgery

Implant surgery is carried out by an ENT surgeon. According to MED-EL, the procedure is straightforward and usually lasts between 1 and 2 hours under general or local anaesthesia. Most people are back on their feet the next day, and the hospital stay may be one or more days, depending on individual needs and what is typical locally.

MED-EL’s guidance on recovery says:

recovery usually takes 1 to 2 weeks
heavy lifting and strenuous exercise should be avoided for 2 to 4 weeks
any mild to moderate pain afterwards can usually be managed with ordinary painkillers

Your surgeon will explain the usual risks and give you aftercare instructions. Always follow their advice.

Step 4: Activation day

The area needs time to heal first. MED-EL says that about four weeks after surgery comes the first fitting, often called “activation day”. This is when the audio processor is switched on for the first time and its settings are adjusted to suit the person.

Keep expectations gentle. MED-EL explains that what an implant sounds like depends on factors such as the type of implant, any remaining natural hearing and how long the person has had hearing loss. With time, practice and follow-up fittings, the brain learns to make sense of the new signals.

Step 5: Rehabilitation, the step that makes the difference

MED-EL puts it simply: “The most important step to hearing is rehabilitation.” Learning to understand sound through an implant takes practice. MED-EL says rehabilitation matters for children and adults alike, and that regular practice brings faster and better progress.

Rehabilitation usually combines:

sessions with a speech and language professional
listening exercises at home, built into everyday routines
follow-up appointments to fine-tune the processor settings

For children, families play a huge part: talking, reading and playing together all become part of learning to listen. MED-EL also offers free rehabilitation materials and apps. At Harmony, our listening and speech therapy supports this stage, with sessions shaped around each person.

Life with a cochlear implant

Many families worry that an implant will limit everyday life. MED-EL’s guidance suggests otherwise.

MRI scans

MED-EL states that its current implants are designed to allow MRI scans under specific conditions. For example, it lists the SONATA 2 implant for MRI at 3.0 Tesla and the CONCERTO 2 at 1.5 Tesla without surgery, unless surgery is required for diagnostic reasons. Always tell the radiology team about your implant.

Sport and play

MED-EL says there are few restrictions on sport. Wear a helmet wherever one is normally used and protect the implant area from direct knocks. It also advises removing the processor before playing on plastic playground equipment, which builds up static electricity.

Water

For swimming and water sports, MED-EL recommends using its WaterWear accessory to protect the audio processor. Check the guidance for your processor model.

Upgrades without new surgery

The implant stays in place for many years, but the technology outside can move forward. MED-EL explains that a new audio processor plus a fitting gives access to the latest technology with no further surgery, and that its implant system has upgradeable firmware so new features can arrive as updates.

How Harmony supports you and your family

Harmony is an authorised MED-EL agent in Amman. We work alongside ENT surgeons, who carry out implant surgery, and focus on the care around it.

answer your family’s questions about MED-EL implants and audio processors

After surgery, we offer:

follow-up care for implant users
audio processor checks and upgrades
genuine MED-EL parts and accessories
listening and speech therapy to support rehabilitation
