Cochlea

 

Our hearing or auditory system can be broadly categorized into two parts- peripheral and central. The peripheral hearing includes the outer, middle, and inner ear. The outer ear consists of eardrum, auricle and ear canal. Middle ear contains malleus, incus and stapes. These three small bones are collectively denoted as ossicles. Malleus connects to the eardrum linking to the outer ear and the stapes connects to the inner ear. Inner ear has cochlea that is further connected to the central hearing system by auditory nerve. Cochlea consists of several special fluids which play an important role in hearing mechanism. The central hearing system consists of the auditory nerve and an incredibly complex pathway through the brain stem and onward to the auditory cortex of the brain.

Sound waves or simply the vibrations in our surroundings are collected by the auricle and are further channeled into ear canals. These sound waves vibrate the eardrum. Now, these eardrum vibrations are moved to the ossicles present in middle ear. From here vibrations are transferred to the cochlea in the inner ear.

Cochlea consists of thousands of hair cells that are sensitive to a wide range of such vibrations. High pitched sounds stimulate hair cells in lower portion of cochlea whereas the low pitched vibrations stimulate hair cells in the upper part. After detecting the frequency or pitch of a sound, each hair cell generates nerve impulses that are transferred immediately along the auditory nerve.

Auditory cortex is the hearing center in the brain. Here several such vibrations are converted into meaningful sound. This whole process takes place within a fraction of a second.

PROCEDURE OF COCHLEAR IMPLANT

December 12, 2020 0

For people who have undergone severe hearing loss or any form of inner-ear damage, cochlear implant is the most ultimate solution. It is an electronic device that partially restores hearing. If you have not been benefitted from any hearing aid yet, cochlear implant is there to sort your all worries.

It is different from all other conventional hearing aids which amplify sounds. It does not involve any process of sound-amplification but sets the damaged portions of the ear on job to deliver sound signals to the auditory or hearing nerve.

Cochlear Implant

It is technologically advanced equipment and also uses a sound processor that fits behind the ear. There exists a receiver that has a role to transfer signals to electrodes implanted in the inner ear, also called cochlea. These signals stimulate the auditory nerve which further transfers them to the brain. Now, the brain interprets these signals as sounds.

The sound that we are referring to is different from the one that we know as normal hearing. Our brain also needs a course of time to get familiar with these signals received from cochlear implant. Initially, there arrive certain issues but within a span of six to eight months, a patient gets immensely comfortable with cochlear implant and regains his hearing

The audiology vertical at AHRI Gwalior is the best institute in the region to undergo cochlear implant. With a team of highly qualified and well-experienced doctors, the institute offers diagnostic evaluations to people having speech, hearing, language, and communication difficulties. It is committed to ensuring excellent outcomes for the patients by the effective use of technology, taking care of their satisfaction and safety as well.

Being pioneered in Madhya Pradesh, the audiology vertical at AHRI Gwalior provides the best cochlear implant accompanied by the best possible care, and that too at nominal expenses.

Cochlear implantation for children

January 18, 2020 0

Cochlear implantation in children:-

How we hear?

The eardrum vibrations caused by sound waves move the chain of tiny bones (the ossicles – malleus, incus and stapes) in the middle ear transferring the sound vibrations into the cochlea of the inner ear. This is where the streams of nerve impulses are converted into meaningful sound.

 

Parts of ear:

  1. Outer Ear :
  2. Middle Ear: Converts sound waves in to vibrations.
  3. Inner Ear (Cochlea): converts vibrations into electrical impulse. Theses electrical impulse travel to brain via nerve of hearing (Cochlear nerve)

 

What is cause of Hearing Loss in children?

In children hearing loss can be congenital (from birth) or acquired (after birth). Acquired can be due to various infections or trauma, etc. 

 

Hearing loss can also be classified as per language development as follows 

  1. Pre-lingual –hearing loss developed before child could start speaking, it can be either congenital (from birth) or acquired (after birth).
  2. Post-lingual – hearing loss developed after child started speaking. It means it is acquired.

 

Cause of hearing loss is any defect in the transmission of sound through the ear. It can be 

  1. Conductive – Caused by defect in middle or external part of ear. It can usually be treated by some medications. Less frequently a surgery is required to correct this type of hearing loss
  2. Sensori-neural – Caused by defect in nerve of hearing or cochlea. Mild to moderate hearing loss can be treated by hearing aid whereas severe to profound hearing loss requires Cochlear Implant surgery

 

Burden of Hearing loss?

In US Significant bilateral hearing loss is present in ~1 to 3 per 1000 newborn infants in the well-baby nursery population, and in ~2 to 4 per 100 infants in the intensive care unit population. 

In India, 63 million people (6.3%) suffer from significant auditory loss. Four in every 1000 children suffer from severe to profound hearing loss. The estimated prevalence of childhood onset deafness to be 2%

 

How to assess Hearing loss in new born and small children?

Detection of infant hearing loss requires universal screening of all infants. Screening by high-risk registry alone (eg, family history of deafness) can only identify ~50% of newborns with significant congenital hearing loss. Reliance on physician observation and/or parental recognition has not been successful in the past in detecting significant hearing loss especially in the first year of life.

Tests for screening include otoacoustic emissions (OAE) and auditory brainstem response (ABR / BERA). Both test are noninvasive, quick, and easy to perform, although each assesses hearing differently. Aim is to initiate necessary intervention by 6 months of age.

 

What is a Cochlear implantation?

A cochlear implant is an electronic medical device that replaces the function of the defective inner ear. Unlike hearing aids, which make sounds louder, cochlear implants do the work of damaged parts of the inner ear (cochlea) to send sound signals to the brain.

Most important thing is early diagnosis. Management of deaf and mute child should be started as early as possible. Success of cochlear implant is more if it is done by the age of 3years. Success rate decreases with advancement of age of child.
