I suffer from tinnitus and high-frequency hearing loss caused by problems within my inner ear. I went to many ENT docs in the Phoenix/Scottsdale area before heading to the Mayo clinic.
Although i'm not sure if the doctor I went to does this procedure, he is the one I settled on in the end:
I know you have to request an appointment and go through an approval process to go to the Mayo clinic, but this should help point you in the right direction.
I encourage you to contact me (via the EmpowHER messaging system) if you need any other information (or if you'd like to chat more about this).
