Cochlear Implant Advances and Outcomes


The human auditory system, an essential facet of our sensory experience, is fundamental to the overall human condition. Cochlear implants, a revolutionary leap in auditory technology, play a transformative role in restoring hearing abilities for individuals grappling with severe to profound hearing loss. Diverging from conventional hearing aids, cochlear implants establish a direct interface with the auditory nerve, circumventing damaged components within the inner ear and rekindling a connection to sound perception.

While cochlear implant surgery doesn’t fully emulate natural hearing, it stands as a remarkable intervention significantly amplifying auditory function and enhancing speech comprehension. This surgical procedure is especially recommended for individuals who find limited benefit from traditional hearing aids. The intricate process entails implanting an internal component beneath the skin, intricately linked to an external component worn discreetly behind the ear.

What is cochlear implant surgery?

A cochlear implant functions as a tool designed to facilitate auditory perception and language comprehension. The surgical process involves the insertion of the implant within the ear, positioned behind it, and subsequent activation through an external component. Executed as an outpatient procedure, the surgery is conducted under general anesthesia. By circumventing compromised areas within the ear, the cochlear implant directly transmits sound signals to the auditory nerve, facilitating an improved hearing experience.

Who needs cochlear implant surgery?

  • Individuals with congenital hearing impairment in children
  • Individuals experiencing severe to profound hearing impairment
  • Individuals who depend on a combination of sign language and hearing aids
  • Individuals utilizing hearing aids without deriving significant benefit from them

What is the functioning of a cochlear implant?

A cochlear implant comprises two integral components:

External Component

The External component is positioned externally, situated behind the ear. It incorporates a microphone for sound recognition, a speech processor that converts identified sounds into digital signals, a coil transmitter responsible for relaying signals to the internal component beneath the skin, and a power source or battery.

Internal Component

Referred to as the implant, the internal component encompasses a receiver and an array. The receiver accepts digital signals and directs them to the acoustic nerve, while the array stimulates the cochlear nerve, facilitating sound recognition.

How is cochlear implant surgery performed?

Cochlear implant surgery is conducted under general anesthesia. A small incision is meticulously made behind the ear to reach the mastoid bone, where the internal component is surgically implanted. Subsequently, electrodes are delicately inserted into the cochlea and securely stitched to the incision site. The internal component incorporates a magnet, and the external component is affixed to it upon placement on the skin behind the ear. Dr. Shree Rao adeptly concludes the surgical procedure within a two-hour timeframe, allowing for a recovery period of approximately four to five weeks.

Cochlear implant surgery recovery time

Recovery from cochlear implant surgery typically becomes evident around the fourth week. The activation of the implant typically occurs in the third week, enabling the individual to experience auditory sensations post-activation. Dr. Shree recommends engaging in speech recognition therapy following implant activation to enhance speech and communication skills more efficiently. Participation in audio training and speech therapy is essential for improved hearing and communication skills compared to individuals who forego such interventions. Consistent attendance at follow-up sessions is necessary to assess hearing performance and enhance speech conditions over time.

How will a cochlear implant benefit hearing?

  • Capable of clear hearing and responsive interaction
  • Facilitates easy communication and the establishment of social connections
  • Effortlessly communicates via telephone
  • Enables joyful connections with family and friends
  • Eliminates the necessity for reliance on sign language
  • Able to hear and comprehend speech even in crowded environments
  • Enhances the enjoyment of favorite movies or music
  • Promotes accelerated learning and adaptation to the environment in children

In pediatric cases, the activation of the implant generally takes place between the third and fifth week post-surgery, marking the initiation of sound perception for the child. Nonetheless, ongoing speech therapy and auditory training remain essential to facilitate sound recognition and comprehension of speech. Through consistent therapy and training sessions, children can typically achieve significant progress in hearing and communication within an 8-12 month timeframe. Conversely, for adults and senior citizens, the recovery period is comparatively shorter. Dr. Shree Rao overseas post-surgery care, contributing to a swift and efficient recovery for patients.
