A cochlear implant is a surgically implanted electronic device that provides a sense of hearing to individuals with severe or profound hearing loss. The external microphone converts sound waves into electrical signals, which are processed by the speech processor. The transmitter coil sends the signals to the receiver-stimulator, which is implanted in the skull behind the ear. The receiver-stimulator converts the signals into electrical pulses that are sent via the electrode array to the auditory nerve. These pulses stimulate the nerve, creating a sensation of hearing.

Surgical Procedure for Cochlear Implantation: A Step-by-Step Guide
Before we jump into the surgery, let’s remember that a cochlear implant is like a bionic device that helps people with severe hearing loss hear again. It’s not a magic wand, but it can make a world of difference.
Step 1: Mastoidectomy
Hold your breath for this one! The surgeon will create a small opening behind your ear called a mastoidectomy. Think of it as a tiny window to access your inner ear’s attic, where the cochlea lives.
Step 2: Inserting the Receiver-Stimulator
Time to plant the receiver-stimulator, the powerhouse of your cochlear implant. This small device will be tucked snugly under the skin behind your ear, ready to receive signals and send them to the electrode array.
Step 3: Placing the Electrode Array
Now for the tricky part. The surgeon will gently insert the electrode array, a thin bundle of electrodes, into your cochlea. These electrodes will act as tiny wires, stimulating the nerve cells in your inner ear.
Recovery:
Once the surgery is complete, it’s time to rest and heal. The incision behind your ear will take a few weeks to fully heal, and you’ll need to avoid any activities that could strain the area.
