|
what can the reflex response of the stapedius muscle show?
|
if absent, then we are concerned about an acoustic neuroma or otosclerosis (bony growth)
note: Stapedius muscle contracts in response to loud sound |
|
|
Acoustic signals generated by normal inner ear
Assesses auditory function through the level of the cochlea Generated by outer hair cells in cochlea Elicited by direct acoustic stimulation and recorded by microphone in ear canal Appropriate for all ages Tells us the outer hair cells are functioning NOT an actual test of hearing- provides information about hearing sensitivity describes? |
Otoacoustic Emissions (OAE)
|
|
|
what type of hearing loss Arises from problem in outer or middle ear that reduces sound conducting ability?
examples? is the problem cochlear? *** |
Conductive Hearing Loss
Outer ear- cerumen impaction, otitis externa- “swimmer’s ear” Middle ear- otitis media, fluid, otosclerosis, disruption of ossicular chain Problem is not in cochlear or auditory nerve Good word recognition (as long as volume is high enough) |
|
|
what type of hearing loss is Caused by problems in the cochlea (sensory) or auditory nerve (neural)
examples? *** |
Sensorineural Hearing Loss
“nerve deafness” Presbycusis- aging Noise induced hearing loss Becoming more common in young people May have poor word recognition “I can hear you, but I can’t understand you” Acoustic Neuroma Ototoxicity |
|
|
“I can hear you, but I can’t understand you”
would be what kind of hearing loss? |
Sensorineural Hearing Loss
|
|
|
drugs that can cause ototox
|
Can't Void And Listen Directly
Cysplatin Vancomycin Aminoglycosides Loop Diuretics |
|
|
Sudden loss of hearing in one ear
Often accompanied by at least one of the following symptoms: Tinnitus Pressure Pain Vertigo ****** |
Sudden Sensorineural Loss
|
|
|
pt has Sudden Sensorineural Loss what should you do?
** |
remember: this is a Sudden loss of hearing in one ear
Often accompanied by at least one of the following symptoms: Tinnitus Pressure Pain Vertigo **you must Check hearing with handheld screener or tuning forks** **Immediate referral to ENT physician** if no indication of puss, bulging tympanic membrane, or fever Treatment cannot wait! Give corticosteroids or pt can lose hearing |
|
|
an objective was to define when you need an ENT referral...there are 6 of them
* |
Recurrent episodes of Otitis Media (4 or more in one year)
Persistent fluid for more that one month. SNHL on patient less than 18 years old. Asymmetrical hearing loss Sudden SNHL with no obvious ear pathology.' Any symptom such as vertigo or tinnitus that persists. |
|
|
This Test:
**Assesses middle ear status** - Probe tone introduced into ear - Amount of sound reflected by TM measured by probe in ear canal as pressure in ear canal is varied - Gives information re: effusion & negative pressure **Tells us if there is fluid behind TM** ****** |
Tympanometry
|
|
|
You want to try and diagnose hearing problems in children by __ months and amplify hearing by __ months in order to have optimal language ability
|
Dx = 3 months
Amplify = 6 months** |
