We just completed the 20th dive on a patient with ISSHL a week ago and I am excited to say that while she did not regain 100% of her hearing back in the affected ear, she did regain partial hearing.
We were able to get her into our program on day 13 after the initial hearing loss and she stayed on oral steriods the entire time. The first 9 treatments were at 2.0 ata and when she started getting some response, the doctor continued her for a full 20 treatments at 2.4 ata with a 10 minute air break during each one.
She did not take weekends or holidays off as we couldn't tell by the studies whether that would be a disservice to her or not. She also has an insurance that I had to get pre-authorization for the treatments, but once I did, they were covered by her insurance (Coventry).
As I get more, I will let you know how it goes.
