Cochlear Implant Failure – Part 9 Video Talk by Dr Akbar Abbas

Cochlear Implant Failure: Causes, Risks, and Preventive Measures

---

Introduction

Cochlear implant failure is a common concern among patients and parents considering or already using these advanced hearing devices. As Dr. Akbar Abbas, ENT Specialist and Cochlear Implant Surgeon, explains, understanding how the device works and how to care for it can significantly reduce the risk of failure and extend its lifespan.

How Long Does a Cochlear Implant Last?

A cochlear implant is a rechargeable electronic device designed to restore hearing in individuals with severe hearing loss. It has two main parts:

• Internal component: Surgically implanted under the skin behind the ear.
• External component: A sound processor worn over the ear and connected to a charger.

The internal part usually comes with a 10-year warranty, while the external speech processor is covered for about 2–3 years.

Failure Rate and Common Causes

Cochlear implant failures are rare—about 1–2%. However, understanding where problems can occur helps patients take preventive steps.

External Device Failures

These often result from mishandling or water exposure, such as:

• Letting water enter the processor.
• Dropping or physically damaging the device.
• Attempting unsafe drying methods (sunlight, stove, microwave, or refrigerator).

Such practices can permanently damage the processor. Any issue should be checked by a qualified audiologist or service provider—not handled at home.

Internal Device Failures

The internal implant may fail for two main reasons:

1. Hard Failure:
   When a clear cause is identified, such as broken or displaced electrodes, trauma to the head, or physical damage. These are less frequent.
2. Soft Failure:
   When the implant stops functioning gradually without a visible cause. The electrodes may stop responding despite stimulation. Soft failures are slightly more common and usually require device replacement.

If an implant fails within the 10-year warranty, manufacturers typically provide a free replacement and surgical support for re-implantation.

Preventive Measures

To minimize the risk of device failure:

• Protect the implant area from head trauma or direct impact.
• Avoid water exposure—do not swim, bathe, or dive while wearing the external processor.
• Teach children careful handling habits during the early years.

---

Device Upgrades and Maintenance

The external speech processor typically lasts five to six years before replacement or upgrading becomes necessary due to:

• Normal wear and tear from daily use.
• Technological updates offering improved sound processing and comfort.

Regular follow-ups with your audiologist help keep your implant functioning optimally and ensure timely upgrades when needed.

Conclusion

Cochlear implants are reliable, long-lasting devices that can dramatically improve hearing and quality of life. Failures are rare and often preventable with proper care, safe handling, and regular professional maintenance.
