Exam 1 Part 3 Flashcards
Includes the cochlea and 8th cranial nerve
Sensorineural
Cochlear hair cells are damaged, considered permanent damage
Sensorineural hearing loss
How do you treat sensorineural hearing loss?
Hearing aids and cochlear implants
Conductive and sensorineural hearing loss
Mixed hearing loss
What is considered sensory hearing loss?
If cochlear hair cells are damaged
What is considered neural hearing loss?
Damage to the cranial nerve
Damage beyond the cochlear
Retrocochlear
Stimulus being delivered to ear by air
Air conduction
What does air conduction test?
Outer, inner, and middle ear
Delivering stimulus to ear by bone
Bone conduction
What areas do we put bone conduction tests on?
Mastoid process, forehead, teeth
What does bone conduction test?
Directly tests the cochlea (sensorineural system)
Difference between air conduction and bone conduction that determines conduction loss
Air bone gap
Testing both sides of the ear
Binaural
Testing one ear
Unilateral/ monaural
Not measuring hearing, can only assume that if physiological functions are working, hearing is also functional
Neurophysiological
Covering 1 ear to make sure hearing is from the other ear
Masking
Softest sound a person can hear
Threshold
What are 3 characteristics of conductive hearing loss?
- AC outside of normal
- BC within normal
- air bone gap
What are 3 characteristics of sensorineural hearing loss?
- AC outside of normal
- BC outside of normal
- AC = BC
What are 3 characteristics of mixed hearing loss?
- AC outside of normal
- BC outside of normal
- Air bone gap
What are the 3 classifications of hearing loss?
Degree, type, configuration
How much the hearing loss is (mild, normal, profound, etc)
Degree
What are 3 types of hearing loss?
Conductive, sensorineural, mixed
Degree of hearing loss is determined by _____
Air conduction
