51
What is the conductive hearing pathway
External ear through the middle ear (conductive phase)
52
What is the sensorineural hearing pathway?
Involves the cochlea & the cochlear branch of CN VIII
53
Air conduction (AC)
Sound waves travel through the air & are transmitted from the external & middle ear to the cochlea
54
Bone conduction (BC)
Used for testing purposes
Bypasses the external & middle ear
A vibrating tuning fork, placed on the head, sets the bone of the skull into vibration & stimulates the cochlea directly
55
In an individual with normal hearing which is more sensitive air conduction (AC) or bone conduction (BC)
Air conduction is more sensitive than bone conduction
56
Conductive hearing loss (external and middle ear) causes:
External:
- cerumen impaction
- infection (otitis externa)
- Trauma
- Squamous cell carcinoma
- Benign bony growths (exostosis, osteoma)
Middle:
- Otitis media
- Congenital conditions
- Otosclerosis
- Tympanosclerosis
- Tumors
- Tympanic membrane perforation
57
Sensorineural hearing loss (inner ear) causes:

- Viral infections: rubella, cytomegalovirus
- Meniere disease
- Noise exposure
- Ototoxic drugs
- Acoustic neuromas (hearing & balance issues)
58
How do you communicate with someone who has conductive loss compared to sensorineural loss?
Conductive = talking louder helps
Sensorineural = talking louder is worse and patient only hears mumbling

Tinnitus (ringing in the ear) assoc. w/ fluctuating hearing loss and vertigo
66
Vertigo
Sensation of true rotational movement of the patient or the surroundings.
- Problem in the labyrinths of the inner ear

Considered unlikely until viral URI symptoms persist more than 7 days; both purulent drainage & facial pain should be present for diagnosis
- nasal obstruction & smell disorder
70
How do you test auditory acuity or gross hearing
The whispered voice test
- detects significant hearing loss > than 30 dB
- Have the patient occlude one ear
- Stand arms length behind the patient & whisper a combo of 3 letters and numbers
- formal hearing test is still the reference standard
71
What is the Weber test used for ?
Test for lateralization.
- set the tuning fork into light vibration & place on top of the patients head
- Can they hear it on one side or both?
Normal = vibration is heard in the middle or equally in both ears
Patients w/ bilateral conductive or sensorineural deficits will not lateralize
72
What is the Rinne test used for?
Compares air conduction and bone conduction.
- lightly vibrating tuning fork is placed on the mastoid bone
- when the patient can no longer hear the sound , quickly place the prongs of the fork close to the ear canal
Normal= sound is heard longer through air than bone (AC > BC)
Conductive hearing loss = if sound is = or BC > AC
Sensorineural hearing loss = will test normal
