25
euschian tube S+S
popping and cracking sound (from a partial blockage), aural fullness, fluctuating hearing, dyscomfort (barometric pressure changes)
26
what will the TM look like in a case of euschian tube dysfunction?
hypomobile due to the build up of fluid
27
how can we treat euschian tube dysfunction?
pop ears against closed nostrils *DO NOT due this if there is an active intranasal infection -decongestant -no barometric pressure changes -balloon dilation of the tube
28
complications of euschian tube dysfunction
developing serous otitis media
29
what predisposes you for a euschian tube dysfunction?
having a patulous tube (wider) bc it is easier to get infected
30
there is a high chance chronic otitis media is caused by what?
food or inhalant allergy that can help an urti spread to the ear
31
S+S of chronic OM
-otorrhea, conductive hearing loss, perforated TM that is draining, macerated auditory canal with granulation tissue, might have cholesteatoma
32
what does it mean if you have pain on top of a chronic otitis media and why?
you probably have an AOM as well because pain is NOT associated with chronic otitis media
33
how are we diagnosing chronic OM (tests?)
-draining and culturing if there is a cholesteatoma -CT or MRI if it has spread (intratemporal and intracranial processes, labyrinthitis, ossicular or temporal erosion and abscess)
34
how can we treat chronic otitis media
-ear canal irrigation -granulation tissue removal -systemic antibiotic therapy -tympanoplaty (if the pt is not at risk for learning problems you can monitor for three months and wait to fix it) -topical antibiotic drops (ofloxacin, ciproflaxacin with dexamethasone) -oral cipro for pseudomonas -antihistamine, decongestant, corticosteroid, -surgery (myringotomy, mastoidectomy or TM) if the hearing is impaired -elimination diet to find allergy
35
if they have cholesteatoma and chronic OM what might they have?
acute OM on top of the chronic
36
recurrent acute OM criteria
-3 or more OM in a 6mnth period or during respiratory season -more than 4 in one year
37
how to treat recurrent AOM
-prophylactic antibiotics -amoxicillin 20mg once a day 1-3 months -reduces recurrent 40-50 percent
38
reccurrent AOM risk factors
-cleft palate, craniofacial deformities, down syndrome, day care, smoker, first episode was under 6 mnths of age, not breast fed, native american or inuit
39
what can cause acute OM?
urti
40
non severe illness AOM
-mild otalgia and fever <39 celsius
41
severe illness
moderate to severe otalgia fever >39 celsius
42
when to treat AOm vs when to observe
child under 6 mnth treat STAT -6mnth to 2 years you can observe
43
S+S of AOM
irritability, difficulty sleeping, fever, nausea, vom, diahrrea, perforation, purulent and serosanguineous otorrhea, headache, confusion, neurological signs, facial paralysis, vertigo
44
what suggests a spread of AOM?
-neurological signs indicate a potential abscess or mastoiditis -facial paralysis or vertigo suggests extension of the fallopian canal or labyrinth, swelling, tinnitus (less common), effusion
45
t or f aom can also cause nystagmus
t just less common -horizontal or jerk type
46
facial paralysis with AOM means?
disease in the temporal bone
47
swelling of posterior auricle area means?
mastoiditis
48
purulent conjunctivities with AOM means?
haemophilus influenza
49
signs of AOM
-erythmatous TM and otoscope light displacement -hypomobilization with insufflation -acoustic reflectometry detects middle ear fluid -fluid bulging -decrease hearing and otalgia (symp)
50
how can breast feed cause AOM
-if reclining the milk can go into the tubes -it can also decrease the risk tho due to IgA and IgG
51
how to treat AOM
-analgesiac, decongestant, antihistamine, myrigotomy, tympanocentesis, self resolving, nsaids, topical agents, otikon otic, narcotic algesia (codeine or analogs), tympanostomy, azithromycin/clindamycin, PNC, cefdinir, cefpodoxime -10 day regimen
52
topical agents for aom
benzocaine, american otic, auralgan
53
why no aspirin to small kids?
avoid reye syndrome that would harm the liver
54
repetitive AOM can lead to?
hearing loss
55
unresolved AOM can lead to?
euschian tube dysfunction
56
most common age for AOM
3mnth to 3 yrs, peak at 6-18 mnths
57
what i the next step if the pain worsens/ failure to respond 3-5 days
axoxicillin 80-100 mg 10 days in a low risk child -still nothing aaugmentin, ceftin or azithromycin
58
cause of menier disease
-fluid in the semicircular canal
59
meniere symptoms:
-vertigo, hearing loss, tinninut (main three) -aural fullness -episodic -vertigo is the symp that comes after the first few
60
t or f menier hearing loss is perm
T, it starts as temporary then becomes permanent
61
menier attacks usually get better in?
5 years
62
menier treatment goal
reduce serverity of the attacks
63
meniere treatment
-antiemetic, antinausea, anti vertigo med therapy -furosemide (wont make it worse)/ diuretic to decrease water -no caffeine/ alc -vestibular suppresant and antianxiety drug -surgery
64
vertigo treatments
antihistamine, prochlorperazine and scopolamine
65
what is peripheral vertigo
secondary disorder of the inner ear/ 8th cranial nerve
66
what is central vertigo
2ndary disorder of the vestibular nuclei and their brainstem/ cerebellum pathway
67
what can some drugs cause?
benign positional vertigo -aminoglycosides, chloroquine, furosemide
68
what infections can cause BPV?
shingles, labyrinthitis, neurosyphilis, ototis media, vestibular neuronitis, menier, tumor, trauma, ms,
69
pathology of bpv is?
displacement of the otoconial crystals which should be in the saccule and utricle
70
