Causes
of Hearing Loss
 Parents
who have just received word that their child has a hearing
loss can display a wide range of reactions. A common feeling
that most parents experience is wondering what caused their
child's hearing loss.
This section will help parents begin
to answer that question. We will walk you through the process
that medical professionals use to discover the cause of
a hearing loss and determine the appropriate treatment.
The emphasis will be on some of the more common causes of
hearing loss. Trying to come up with an answer to the question
of what caused a hearing loss is somewhat like putting together
a jigsaw puzzle. Unfortunately, we do not always have all
the pieces to that puzzle and there is not a final picture
to guide us. Each physical finding, medical test result,
and piece of family medical history provides a piece of
the puzzle. Sometimes, one of those pieces can "fill
in" a big enough section of the puzzle that the medical
professionals feel confident that they know the cause of
the hearing loss. It is also possible that after all the
testing, after all the questioning, and after all the examinations,
the answer remains unclear. You may be told that the cause
of the hearing loss is still unknown.
