Hundreds of thousands of people worldwide have benefited from cochlear implants in India since they were first implanted in adults in 1984. Since then, several advancements have been in the field of cochlear implant technology.

Cochlear Implant, as it is today, has evolved from ceramic and titanium to silicone casing, from 8 to 16 or 24 active electrodes, and from big and body-worn sound processors to a single-unit device.

Many of the existing cochlear implant users can greatly benefit from the latest in trend –  fully implantable cochlear implant systems. These wireless cochlear implants without external hardware provide the following conveniences to its users:

  • The device eliminates the need for constantly wearing and/or carrying the external components as in the former implant systems.
  • The system behind the new cochlear implant makes use of the natural microphone of the inner ear instead of a skull-mounted sensor to collect sound waves.
  • They can be wirelessly recharged at a relatively fast rate and could run for about eight hours on each charge, thus minimizing disruptions to a patient's lifestyle.
  • Once fully charged, the device can even be used to charge various configurations of the implant. These may include a fully implantable single unit, a wired or a proximity system.
  • They help get rid of distracting background noises.


This new “cable-free” cochlear implant system is designed to pick up the sound vibrations in the delicate bones of the middle ear. Instead of being sent to the cochlea, these sound waves are sent to a microchip implanted in the ear that converts them to electrical signals passed to an electrode in the cochlea.

The latest trend has promised its users an improved possibility of communication, development of language skills, spoken words recognition, and improved media enjoyment.

These milestones achieved in the development of the cochlear implants is a result of the evolution of technology and coding strategies, close collaboration between engineers, surgeons and audiologists, and constant improvement in the use of computer science.

The best cochlear implant hospitals in India keep themselves updated as per the recent advancements in the field of ear surgery. People suffering from profound deafness can pay a nominal cochlear implant in India and reap the benefits of the most advanced techniques available in the field of ENT surgery.
