Ear Anatomy and Function

The ear has two primary functions: hearing and balance.
The middle ear includes the eardrum (tympanic membrane) and three small bones (malleus, incus, and stapes).
The eustachian tube connects the middle ear to the nasopharynx.
The inner ear, situated within the temporal bone, is separated from the middle ear by the oval window.
The inner ear contains the cochlea (hearing) and semicircular canals (balance).
Cranial nerves VII (facial) and VIII (vestibulocochlear) are associated with the inner ear.
Balance is also influenced by visual, vestibular, and proprioceptive systems.
Problems in any of these balance-related systems can lead to balance issues.

Middle Ear Disorders

Nurses should recognize various middle ear disorders, including infections, tumors, and balance/coordination problems.

Hearing Loss Types

Hearing loss can result from environmental or occupational noise.
Conductive hearing loss is caused by factors like otitis media, otosclerosis or a foreign body (e.g. impacted earwax).
Sensorineural hearing loss is due to damage to cranial nerve VIII.
Combined hearing loss involves both conductive and sensorineural components.

Aging affects the ears, causing tympanic membrane thickening (reduced elasticity), loss of sensory hair cells, and reduced ossicle movement.

Earwax and Assessment

Cerumen (earwax) color and external ear canal variations exist depending on client race and skin tone.
Recognizing normal earwax variations is critical during assessment.

Test your knowledge on ear anatomy, its functions, and common disorders. This quiz covers aspects of hearing and balance, as well as various middle ear conditions and types of hearing loss. Perfect for students in health sciences or audiology fields.
