Cochlear Implant:What you need to know (Part1)

 Cochlear Implant: Hope  

A world without sound is lonely.Cochlear implants are the most promising method of giving a hearing  life to the hearing and speech challenged.

There are grossly 2 Type of hearing loss

Post-lingual hearing loss: When a child develops normal speech and then loses it due to some event.
Most commonly post meningitis, a cochlear implant can change lives. But timing is everything.

 
Continue breastfeeding when working

Can your child hear you?

Prelingual hearing deficit: Hearing and speech challenged since birth.Nowadays it’s possible to have excellent results even with babies as young as 12 months.

3 most important things to help children who are hearing challenged:

 

 #1 Early identification is most important.

 If there’s any event before or after birth which can cause a hearing problem, your doctor will ask you to consult an ear doctor.Parents have the biggest chance of detecting whether baby responds by startling to loud hand clapping.

The earlier you know the more you can help.

Why is early detection important?

Your brain is an amazing organ.It is rewireable depending on the stimulus. Nature and quality of stimulus are important.

This brain plasticity or ability to learn is greatest up to age 2 and excellent till age five . Pediatricians call it the 1000 days of promise. It decreases with age and other associated problems.Speech development is deeply interlinked with hearing abilities. What the brain can’t hear the mouth can’t speak.

 
 That’s why the early restoration of hearing can help develop normal speech in the prelingually (speech never developed)hearing challenged.
 
 The post-lingual (speech developed, then list)hearing challenged have excellent results as they already have language skills which are helped after surgery.
 
 #2 Training before implant
 Preimplant language training by sign language (aural-oral) helps in speech development after implant.
Also,  digital hearing aid is prescribed before implantation to help with adjustment to wearing an earpiece.
 

#3 Motivation of parents and child for continuing follow-up and training

 Post-implant continued training to help in the rehabilitation of the child.The family has to be committed towards this goal.
 

 So how can you detect earliest in babies who have never developed hearing and speech?
Tests needed:1)Testing the hearing: BERA/Tympanometry /OAE/ASSR

2)HRCT Temporal bone

3)MRI

Just to check whether the child is hearing BERA or Brainstem evoked response Audiometry test is useful CT /MRI helps to check for congenital structural defects.

  1. I’ve actually observed a cochlear implant operation on a few young children. The results afterwards were amazing.

  2. It’s such a heart breaking thing to have to worry about. This post is a great resource for parents, I’m shooting it off to my sister in law who works with babies daily. Thanks!

  3. Great informative post on cochlear implants. I think it’s great to spread awareness on this issue. I would not know what to do in this situation but this helps and it’s amazing how far technology has come!

  4. Awesome post. I didn’t know much the difficulties with hearing loss and babies but now I am better informed for those around me and my future children.

    Thanks ????

  5. Great post and great advice. I don’t know anyone with hearing loss but I do have children an definitely make sure I’m keeping up with their health

  6. Hi Amrita,

    I loved your posts. They are so informative and many thanks for creating awareness in the society through your posts!
    I have a friend whose nephew got Cochlear Implant last few months ago and glad to share that now he can hear properly! Thanks to all the new innovation and Medical technology advancement that we have a better cure of many diseases!

    1. Thanks Ana,I am so glad you liked this.Yes cochlear implant is a gift to hearing challenged .It changes lives. Only problem. It’s expensive.I am glad to hear the little boy is doing well.Best wishes in his journey.

  7. This is such an informative post! I will share this post with my friend too to spread awareness.

  8. Lots of great advice 🙂
    I know I was lucky with my hearing growing up and only needed to have eartubes put in every once in awhile.
    So, I hope this advice helps parents with young kids that need to be able to hear.
    Thank you so much for sharing it with us 🙂

  9. How interesting! I have a baby who’s only 1.5 years so I’m very into the speech development. Thank you for the insight on hearing, something to look into with her!

    1. Yes babis speak what they hear.They actually start hearing from before birth.So it’s a long journey to speech????

  10. Hello! Interesting blog post. Don’t doctors do this type of checking for kids at yearly check ups?

    1. Good question.
      Doctors don’t do all the tests routinely.Only in children who have some birth event history,or mommy had some infection like Rubella during pregnancy,that’s when we get BERA done.
      Sometimes parents identify hearing problems in very young children,who are otherwise doing great.

  11. This is great info. I’m currently studying for the mcat and just read about the ear. I was definitely curious about hearing challenges.

  12. I’ve read about cochlear implants before and see a few videos about it. It’s truly amazing what they can do for someone, but it’s a major surgery.

  13. Great post. Early detection is important when it comes to all sorts of disabilities. It’s great to see that people who suffer from hearing loss can have it restored thanks to implants.
