Within the past week my brother, who was born with only one ear, lost
all of his hearing and developed bad tinnitus. This occurred less than
a day after getting his teeth cleaned ultrasonically.
Other than a brief mention in the tinnitus faq, I have yet to find in
information about the possible connection between ultrasonic cleaning
and hearing loss.
Any leads or information would be greatly appreciated.
