Hearing Loss?
angelkid45916 asked:
I ‘m doing this report on Sensorineural Hearing Loss[[SNHL]] and I’m very confused.
Is SNHL the same thing as conductive hearing loss??
can SNHL start when you’re a baby , or is that a different type of hearing loss.?– if no, when does it usually start showing up.
and can SNHL only be genetic or is it something you can get if you have to much damage to the ear.

SNHL and conductive hearing loss are very different. There are three parts to ear outer ear – what you see on outside (pinna) and includes the ear canal and the ear drum. The middle ear is filled with air and is behind the eardrum and includes the three bones malleus, incus, and stapes. The inner ear is where the hearing nerve is the cochlea.
Conductive hearing loss is caused by disorders of the outer or middle ear which includes otitis media (ear infection), cholesteatoma, otosclerosis etc. These types of problems can often be treated medically by an ear nose and throat physician with medication or surgery.
SNHL is caused by problems with the cochlea or hearing nerve. This type of loss is permanent and cannot be treated medically. Causes of SNHL include genetics, noise exposure, aging, etc.
Some babies are born with SNHL and some are born with Cond. HL. The baby can be born with no outer ear, a closed ear canal, absence of the bones in middle ear etc. SNHL can be progressive and get worse as one gets older sometimes it stays the same for most of a persons life until aging effects start to add on to hearing loss at 60 years old.
