Candice had her follow up with the ENT today. Additionally, they retested her hearing. The hearing specialist and doctor think she may have some hearing loss. In order to know completely they need to give her an Auditory Brainstem Response Evaluation. This will be scheduled soon.
What is an Auditory Brainstem Response Evaluation (ABR)?
An Auditory Brainstem Response Evaluation (ABR) is a type of test, usually performed for infants and young children, that evaluates how well sounds travel along the hearing nerve pathways from the ear to the brainstem. There are two main types of hearing loss:
- Conductive hearing loss — problems transmitting sound from the outer ear (where sound is collected) to the inner ear. This type of hearing loss can often reverse itself as children grow older.
- Sensorineural hearing loss — problems with the nerves connecting the inner ear to the brain. In the inner ear, tiny hairs on the cochlea act as a neural pathway, transmitting through the inner ear. Usually, problems with these hairs on the cochlea are responsible for sensorineural hearing loss. It is usually permanent and present at birth.
An ABR test, by evaluating the hearing nerve pathways, can identify cases of sensorineural hearing loss. It is a sleep EEG hearing test which shows the softest sounds your child’s ears can detect at various pitches. The ABR compares changes in brain activity to the timing of repetitive sounds to determine whether the particular intensity of sound can be heard.
How is it performed?
There will be three or four small stickers on your child’s head, connected to leads going into a computer. Sounds will be presented through an earphone to each ear separately while a computer analyzes the changes in the brain wave pattern in response to sounds.
Your child should be sleeping for the duration of the test. Young children under the age of six months are not usually sedated, and the test is performed while the infant is naturally sleeping, following a feeding. Children over the age of six months are usually sedated with chloral hydrate.
The test is not painful or uncomfortable in any way, but it is necessary for your child to be asleep in order to obtain clear recordings during the test.
You will be in the room with your child during the test, and the results will be explained immediately afterward.
Otherwise, she has no current infections and is doing well. She has been accepted into the speech disorder clinic but it takes forever to get in. Candice’s appointment is not till October. In regards to Candi’s vocal cords, our doctor is learning more about the research going on in regards to tissue- engineering. They have not done clinical trials yet, but it is coming. In about two years we may have just what we need to help Candice.
One method focuses on injecting gelatin-like materials, composed of soft, strong and long-lasting hydrogels, into damaged tissue to improve its pliability and prevent scar formation. In the second approach, the scientists want to form functional tissue from a combination of vocal fold connective tissue cells (fibroblasts), artificial extracellular matrix, and biological cues and mechanical stimuli that capture the mechanical and biological characteristics of the natural organs.

We thank God for his continued watchcare over Candi and all, including the way He is using doctors and research into the incredible creation called “human beings”. We pray for Candi’s hearing and the Lord’s working on, in and through it all.
