Carol,

It is not really a new medical discovery, mostly what has happened

over the last several years is the testing has become more ritual, so the

diagnoses is determined long before they start to see a drop in hearing.

There also seems to be no real pattern to the why and how the losses occur.

We have two daughter with EVA, and the patterns of their losses do not match.

Our youngest daughter was diagnosed with EVA, after a sudden large drop in

hearing. She had normal hearing in one ear, and a mild to severe loss in the

other. One day I put her to bed one child and she woke up the next day,

different. After a visit to the test booth to see what was going on, we

found that she now had a bilateral severe loss. The only thing that happened

that I could put my finger on, was a typical toddler head bump on the corner

of a table. Not even enough to make here cry. After she was diagnosed with

EVA, we went back a had a second opinion on her older sister CT scan and

found that she too had EVA. She had bumped her head many times like kids do,

and there had been no decrease in her hearing. We had the opportunity

through all of this to have both the girls CT scans reviewed by Dr.

Epstien who has done extensive research on EVA. His thoughts where that a

lot of HOH children's EVA went undiagnosed because progression wasn't always

seen. There where things he said we should do, but he also cautioned us on

not feeling like the girls had to walk around the rest of their lives with a

helmet on. The things they knew, where no contact sports that could result

in a major head trauma, a low salt diet and not flying in an air plane.

Anyway..'s loss stayed stable for the next 7 years, Holly's loss I

believe fluctuated often from day to day, and ultimately she ended up with a

profound loss. had a slight decrease in hearing at age 7, which was

enough for us to decide to do get the implant. EVA has been around for such

a long time, it just seems to vary so much in each individual cases that

there is not any real right way or wrong way about it. AGBell can get you in

contact with Dr. Epstien if you are interested in any of his research papers.

Sincerely,

Hi Kerry,

Did the doctor advise against ANY types of activities? I ask because we

have received similar instructions for my son (also EVAS) and are

still in the process of deciding which sports activities to allow. At least

two of the studies I have read specifically mention that " heading " the ball

during soccer has caused overnight, often irreversible hearing loss in

children with EVAS. Other than that, I try to look at each activity to

determine the probability of a blow to the head or a change in intracranial

pressure. (The term " head injury " can be misleading because people often

view it as a traumatic event as the result of an accident instead of

something that can be more subtle.)

It sounds as if the doctor you spoke to doesn't think EVAS is the only cause

of your son's hearing loss but I wonder if he's basing that belief on the

slow progression of the loss. From what I've read in journal articles and

from conversations with others who have children with the condition, EVAS is

often evidenced by an average, gradual loss of about 4 db a year, even

without head trauma.

I wish this wasn't such a new medical " discovery " . I'm getting more

confused by the day!

My son anxder uses bi-cross aids. They are the

Siemens MUSIC. He has no measurable hearing at all in

his left ear and severe/profound loss in his right. He

has had the bi-cross aids since he was aided at age 5

and we have been pleased with the results. He has

never had any confusion issues when trying to figure

out where sounds are coming from and his speech

improved dramatically. The kind he uses has the wire

along the neck, going between the 2 aids.IMO the

bi-cross aids are working very el for him.
