Hearing Loss

I learned last week that Tyrin has a bilateral hearing loss causing him to be deaf in both ears. He was tested at birth and several times since. This latest test was called ABR and looked at his brainstem response (see his picture below). Here is some of the info about his diagnosis:

Sensorineural hearing loss is caused by malformation or damage to the inner ear or auditory nerve. Most often, sensory cells in the inner ear have been lost or damaged. Sensory cells in the inner ear change sound into electrical signals which are sent on to the auditory nerve then interpreted by the brain. Distortion of sound may accompany sensorineural hearing loss. Most people with sensorineural hearing loss can benefit from hearing aids or a cochlear implant.

The audiologist took a mold of his ear to fit him for hearing aids, which we hope will give Ty the ability to perceive more sounds around him including speech.

Hearing loss can be caused by illness, injury, or genetic factors. The cause of 50% of hearing loss remains unknown.

There are a lot of decisions and challenges ahead, but I'm confident in the amount of resources available.
I really appreciate all the love and support offered by friends and family.
