should raise suspicion of nasopharyngeal mass blocking ET orifice
45
What are the pediatric AOM abx treatments
amoxicillin add beta-lactamase coverage (augmentin) or Azithromycin (single dose)
46
what are the indications for tubes
recurrent AOM: > 3 separate episodes in 6 months OR > 4 episodes in 12 months *should have effusion at time of consult
47
What is the most common reason for tubes
chronic non-suppurative otitis media
48
What is the medical management of chronic otitis media
autoinsufflation; +/- steroids; recheck 6-8 weeks; consider allergy evaluation, NO abx unless other sites of bacterial infection
49
when do you refer for chronic otitis media
severe TM retraction failure to improve in 2-3 months persistent UNILATERAL effusion significant hearing loss - especially in children
50
What is cholesteatoma
keratoma or skin where it does not belong congenital or primary secondary or acquires SURGICAL disease
51
what is the presentation of Acute Mastoiditis
>80% have no hx of recurrent OM persistent otorrhea >3wks is most consistent sign of mastoid involvement persistent fever despite abx pain deep or behind the ear, worse at night hearing loss is common elevated WBC
52
What is the treatment of Acute mastoiditis
surgery - mastoidectomy
53
what is vertigo
abnormal sense of motion characterized by a spinning sensation
54
what are the types of vertigo
central (neurology/cardiology) peripheral (otolaryngology) systemic
55
what is Oscillopsia
jumping images
56
what areas are responsible for maintaining equilbrium
eyes labyrinth CNS
57
how is vertigo diagnosed/worked up
audiology: assess peripheral vestibular system imaging: assess CNS Blood tests: assess Systemic
58
What is the gold standard test for vertigo
MRI with Gadolinium contrast
59
what is the most important test with vertigo
audiogram
60
What is the most common cause of vertigo
BPPV (benign paroxysmal positional vertigo)
61
what is BPPV
benign paroxysmal positional vertigo a phantom sensation of motion of elicited by specific changes in head position caused by placing the affected ear downward associated with characteristic eye movements (nystagmus)
62
What is Meniere's syndrome
condition of excess pressure accumulation in inner ear
63
