Front 12

Describe the characteristics of otosclerosis.

Back 12

Otosclerosis is described as the increase in the stiffness of the middle ear. It is an abnormal growth of bone around the footplate of the stapes, which fixes it in place within the oval window. Due to the bone growth, the transmission of sound is affected through the ossicular chain to the inner ear.

middle ear function, an estimation of cochlear hearing loss, and the difference between 8th nerve and brain stem disorders.

Changes to the VIIIth nerve or to the auditory brainstem. Causes can include tumors (e.g., cochleovestibular schwannoma). An ABR test is a good assessment tool for the functioning of the VIII nerve and brainstem.

Front 15

What are symptoms of Retrocochlear hearing loss?

Back 15

Assymetric hearing loss, tinnitus (ringing in the ears), poor speech discrimination, and dizziness.

Front 19

What are characteristics of a conductive hearing loss?

Back 19

Caused from impacted cerumen (ear wax), perforated tympanic membrane, fluid in the middle ear, and otosclerosis. Conductive hearing loss can be medically treated and corrected. With a conductive hearing loss there is a change in the outer or middle ear which affects the conduction of sound to the cochlea.

Front 20

What are characteristics of a sensorineural hearing loss?

Back 20

Caused from excessive noise, ototoxic drugs, and viral illnesses; resulting in damage to the cochlea. Sensorineural hearing loss cannot be medically treatable and is not reversible.

Describe sensorineural hearing loss on an audiogram.

Back 21

bone conduction and air conduction thresholds will be equal and elevated.

Front 22

Describe a mixed hearing loss on an audiogram.

Back 22

There will be an air-bone gap, with thresholds elevated for bone conduction and air conduction.

Front 23

Name what can cause inner ear and cochlear disorders.

Back 23

Embryonic malformations, infections, noise induced hearing loss, inherited conditions, congenital infections (e.g. rubella, sylphillis), acquired viral, fungal, and bacterial infections, meningitis, herpes, mumps, and ototoxic drugs.

Front 24

What are the two branches of the auditory nervous system of the VIII nerve which carry the electrical sound impulses from the cochlea to the brain?

Back 24

vestibular and auditory-acoustic
