A comprehensive resource for parents, caregivers, and healthcare professionals

What is a Cochlear Implant?

A cochlear implant is an electronic medical device that helps provide sound sensation to children with severe to profound hearing loss. Unlike hearing aids that amplify sound, cochlear implants bypass damaged parts of the inner ear and directly stimulate the auditory nerve, sending signals to the brain that are interpreted as sound.

How Cochlear Implants Work

A cochlear implant has two main parts:

  • External Components: Microphone, speech processor, and transmitter worn outside the body
  • Internal Components: Receiver and electrode array surgically placed under the skin and inside the cochlea

Sound is captured by the microphone, processed into electrical signals, transmitted through the skin to the internal receiver, and sent to electrodes that stimulate the auditory nerve.

Purpose and Medical Uses

Cochlear implants are used for children with:

  • Severe to profound sensorineural hearing loss in both ears
  • Minimal benefit from hearing aids after trial period
  • No medical conditions preventing surgery
  • Appropriate family support and commitment to therapy
Age Considerations: Children can receive cochlear implants as young as 12 months old in many countries. Earlier implantation often leads to better speech and language development outcomes.

Common Settings Where Cochlear Implants Are Used:

  • Home environment for daily activities
  • Schools and educational settings
  • Speech and auditory therapy sessions
  • Audiological clinics for programming and maintenance

Types of Cochlear Implants

Type Description Best For
Standard Cochlear Implant External processor with behind-the-ear unit and transmitter coil Most children with bilateral profound hearing loss
Single-Unit Processor All-in-one external processor combining components Active children, easier to manage
Bilateral Cochlear Implants Implants in both ears Better sound localization and hearing in noise
Hybrid Cochlear Implant Combines cochlear implant with hearing aid Children with residual low-frequency hearing

Major Manufacturers

Several companies produce FDA-approved and internationally certified cochlear implant systems, including Cochlear Limited, Advanced Bionics, MED-EL, and Oticon Medical. Each has different features and programming options. Your audiologist will help determine the most appropriate device for your child.

How to Use: Step-by-Step Guide

Daily Application and Use

Step 1: Check Equipment - Ensure the external processor, battery, and coil are clean and fully charged.
Step 2: Insert Battery - Place the charged battery into the speech processor according to manufacturer instructions.
Step 3: Position Behind Ear - Place the external processor behind the child's ear, similar to a hearing aid. Ensure proper fit and comfort.
Step 4: Attach Transmitter Coil - Position the external coil over the internal implant. It will magnetically attach to the receiver under the skin.
Step 5: Power On - Turn on the device. Many processors have indicator lights showing they are working properly.
Step 6: Verify Function - Check that your child responds to sound. Older children can confirm they hear properly.

Daily Maintenance

  • Check batteries every morning and keep spares available
  • Clean the processor and coil with dry cloth daily
  • Check for moisture buildup using drying kit if needed
  • Inspect cables and connections for damage
  • Store in protective case when not in use
Listening Check: Perform daily listening checks using the Ling Six Sounds (ah, oo, ee, sh, s, m) to verify the implant is working across different frequencies.

Precautions and Safety Guidelines

Important Safety Warning: Always remove the external processor before water activities, sleeping, or any situation where it might get wet or damaged.

Medical Precautions

  • MRI Scans: Inform medical professionals about the cochlear implant. Some models require magnet removal before MRI, while newer models are MRI-compatible under specific conditions
  • Static Electricity: Can damage the processor. Use anti-static spray on clothing and have child touch grounded metal before playing on plastic slides
  • Airport Security: Carry identification card. Metal detectors are safe, but inform security personnel
  • Electric Shock Risk: Keep away from electrical hazards and high-voltage areas
  • Head Trauma: Protect the implant site from direct impact. Use appropriate helmets during sports

Activities to Avoid or Modify

  • Contact sports without protective headgear
  • Diving from heights (pressure changes can damage device)
  • Deep sea diving (most implants not rated for extreme depths)
  • Direct exposure to strong electromagnetic fields

When to Contact Your Audiologist

  • Device stops working or intermittent function
  • Child complains of unusual sounds or discomfort
  • Visible damage to external components
  • Redness, swelling, or drainage at implant site
  • Significant decrease in hearing performance
Emergency Situations: If the skin over the implant becomes red, hot, swollen, or drains fluid, or if your child has fever with these symptoms, seek immediate medical attention as this may indicate infection.

Device Care and Maintenance

Daily Care

  • Wipe external processor with soft, dry cloth
  • Check microphone openings are not blocked by dirt or debris
  • Examine cables for fraying or damage
  • Clean coil surface gently with dry cloth
  • Store in dehumidifier or drying kit overnight

Battery Management

  • Rechargeable batteries: Charge fully each night using approved charger
  • Disposable batteries: Keep 2-3 day supply available; typical life is 3-5 days depending on usage
  • Store batteries in cool, dry place away from metal objects
  • Dispose of used batteries according to local regulations

Storage Guidelines

  • Use protective case when not wearing
  • Keep away from extreme temperatures (below 0C or above 50C)
  • Store in low-humidity environment
  • Keep away from young siblings who might damage it
  • Never store with magnet separated from coil

Professional Maintenance

Schedule regular appointments with your audiologist:

  • First Year: Every 3 months for programming adjustments
  • After First Year: Every 6-12 months or as recommended
  • Reprogramming: Needed as child grows and hearing needs change
  • Equipment Check: Regular testing ensures optimal performance

Troubleshooting Common Issues

Problem Possible Cause Solution
No sound Dead battery Replace or recharge battery
Intermittent sound Loose connection Check all cable connections
Coil falls off Weak magnet or hair interference Adjust magnet strength or use headband
Feedback noise Coil too close to processor Reposition coil or processor
