Intro to Aural Rehab
True or False: Hearing loss often co-occurs with other health conditions
True! Higher co-morbidity of type 2 diabetes, cardiovascular disease, fall risk, depression, cognitive decline
What would you expect to observe in otoscopy for a patient with swimmer's ear?
Drainage, pain, redness, swelling of the ear canal
Air bone gaps greater than 10 dB are observed for which type(s) of hearing loss?
1. Conductive hearing loss
2. Mixed hearing loss
What are three disorders of the inner ear?
1. Noise-induced hearing loss
2. Meniere's disease
3. Acoustic neuroma
Describe the difference between rehabilitation and habilitation.
Rehabilitation = restoring a previously lost skill
Habilitation = establishing a new skill
What's the difference between grade 1 microtia and grade 4 anotia?
In grade 1, the pinna & ear canal are underdeveloped but present. In grade 4, the pinna & ear canal is completely absent.
Bone conduction falls in normal range for conductive; bone conduction falls outside normal range for mixed.
500 Hz, 1000 Hz, 2000 Hz
Would you recommend considering a medical model or biopsychosocial model for sensorineural hearing loss?
Biopsychosocial model
False! Basilar membrane contains the sensory hair cells.
Calculate the word recognition score for a patient who missed 4 words out of a 50 word list.
92%
(50-4 = 46/50 = 0.92*100)
What is the transducer set up for masked right air conduction threshold?
Right ear (test ear) = pure tone
Left ear (non-test ear) = masking noise
What is "health" in a biopsychosocial model?
Biological, psychological, and social factors.
Endolymph is located in which duct(s) of the cochlea?
Scala media
What is the purpose of masking in audiologic testing?
Allows you to obtain the threshold of the test ear without the interference of the non-test ear.
What's the primary difference between SRT and SDT?
In SDT, the patient just needs to identify if a word was said - whereas in SRT, the patient must correctly identify the word.
How does listening effort relate to untreated hearing loss?
Untreated hearing loss increases required listening effort.
Describe the expected audiologic findings for a patient with a perforated eardrum.
Conductive loss.
If a patient's air conduction thresholds are at 70 dB across the frequency range and the bone conduction thresholds are at 30 dB across the frequency range, what is the degree and type of hearing loss?
Moderately-severe mixed hearing loss.
This central auditory structure is directly connected to the auditory nerve?
Cochlear nucleus (first stop in the brainstem)
