Conductive Hearing Loss


Conductive hearing loss is a type of
hearing loss that occurs when the sound cannot get to the inner ear. In order to
better understand conductive hearing loss, we need to understand how the ear
works. The way the ear works is sound comes in through the ear canal, hits the
eardrum and goes through the three bones of hearing. The first bone of hearing is
called the malleus. The second bone is the incus, and the third bone of hearing
is the stapes. The stapes, or third bone hearing, interfaces with the
hearing organ called the cochlea. Cochlea means snail shell in Greek and you can
see it’s shaped like a snail shell. Within that, there are little receptor
cells that receive the sound, turn it into a nerve signal and send the message
to the brain. So the problem can occur in three parts of the ear; it can occur in
the outer ear where the ear canal is blocked. The most common cause of
conductive hearing loss in terms of the ear canal is having wax blocking your
ear canal. The second place where it can occur is with the eardrum, you can have
a hole, or what we call a perforation in the eardrum and that will make it so
the sound does not go through to your inner ear as effectively. The third place
where you can have a problem is with your ear bones. You can have a stiffness
of the ear bones, an absence of the ear bones, or a poor connection between any
of the three ear bones that can cause a hearing loss. If you have a problem in
any of these areas then it is called a conductive hearing loss. In order to
better understand this if you have been told you have conductive hearing loss,
