Cochlear implant placement is a surgical procedure for implanting an electronic device into the inner ear to restore hearing in people with severe or complete hearing loss.

A cochlear implant consists of two main parts:

  •  Internal implant: It is placed deep in the inner ear and converts sound signals into electrical ones.
  •  External processor: Located behind the ear and contains a microphone, a speech processor, and a transmitter.

When a person with a cochlear implant hears sound, the microphone picks it up and transmits the signals to the speech processor. The processor converts sounds into electrical signals and transmits them through a transmitter to the internal implant. The internal implant stimulates the auditory nerve, which then transmits signals to the brain, where they are perceived as sound.

The installation of a cochlear implant is indicated for people with:

  •  Severe or complete hearing loss in both ears
  •  Limited benefit from hearing aids
  •  Good auditory nerve and brain stem

The installation of a cochlear implant is usually performed under general anesthesia. It includes:

  •  An incision behind the ear.
  •  Creating a pocket in the skull bone and placing an internal implant.
  •  Installation of electrodes in the cochlea (inner ear).
  •  Connecting the electrodes to the internal implant.
  •  Installing an external processor.

Recovery after the installation of a cochlear implant usually takes several weeks. Patients may experience some pain or discomfort at the incision site. Painkillers may be prescribed. It is important to avoid getting the incision wet and adhere to restrictions in activities according to the doctor's instructions.

The improvement of hearing after the installation of a cochlear implant varies and depends on individual factors. Most patients report significant improvements in speech comprehension and quality of life.

As with any surgical procedure, there are certain risks associated with the installation of a cochlear implant, such as:

  •  The bleeding
  •  Infection
  •  Facial nerve damage
  •  Dizziness
  •  Tinnitus
