HEENT-Ear Flashcards
AOM- acute otitis media
1- Viral
#1 office vistis PEDS < 1 middle ear inf. Pn due to enclosed pressure of fluid Factors- smoke, daycare, supine drinking(anatomic tube structure), M, anatomic
#2. Strep. pneumoniae 30-40%
3. H influenza 21%
4. Moraxella Catarrhalis 12%
S/s- irritable, fever, ea, otorrhea or vertigo. TM: bulging, retract, perforate (holes), dec. hearing. Purlent-yellow section, red, no/displaced cone of light, dull vs shiny
PE- pneumaic otoscopy #1 sign- dec. mobility w/ air puff
Pinna pain w/ movement
AOM TX & complications
TX #1 Abx Amoxicillin (peniclin) esp <2yo Mryingotomy Tympanostomy tubes-drainage NEVER steroid drops
Comps
Perforations, Chronic OM- chronic s/s, w. drainage in canal. Itch #1 sx
Cholesteoma-keratinized, desquamous cell d/t TM perforation. ASX or hearing loss, dizzy
AOM serous
clear fluid in middle ear- VIRAL
Otiis Externa
Infection and inflammation of the external auditory canal #1 sx: local pain (severe-tragus) and itching, erythema, heat, crust Assoc sx- Associated periauricular adenopathy >5yo
TX #1 Staph aureus-crusty
Diffuse OE
“Swimmer’s ear”, P aeruginosa
Hot, humid climate, hot tubs
SX-Canal is erythematous, edematous, some hemorrhagic
white flakes,
TX- topical antibiotic drops w/ steroid. DRY out.
Neo
Malignant OE
Severe necrotizing bacteria infection external auditory canal with invasion into the surrounding tissues including blood vessels, cartilage, and bone.
SX-Immunocompromised, elderly, HIV, DM
Osteomyelitis at base of skull, TMJ, Elevated ESR, CRP typical, local heat, erythmetous
TX- P aeruginosa in >95% of cases
MOE TX complications
TX
Topical ABX don’t work, need systemic
Systemic Cipro treatment of choice
IV until improving, then switch to oral (6-8wks)
Levofloxacin probably acceptable, no data
Vertigo
vestibular disease-Sense motion when there is no motion, or exaggerated sense of motion in response to body movements
ETI-labyrinthitis, BPPV, Meniere’s syndrome, migraine
triggers (salt, stress, bright lights)
DX:-Asso sx, Duration is key DX, CN exam, cerebeller
eyes (nystagmus), ears, Dix-Hallpike maneuver Gold
Peripheral: sudden onset, hearing loss and tinnitus, nausea, no fever, no other neuro
Central: gradual onset, no auditory sx
BPPV TX & complications
TX- ENT or Neurology if vertigo persists or CNS lesion suspected
D-H: quickly lowering supine with head extending over edge of bed 30 degrees lower than body, turned either to left or right; elicit delayed nystagmus in BPPV; nonfatigable nystagmus indicates CNS etiology
Conductive Hearing Loss
Eti:
dysfunction of external or middle ear
Acute: cerumen impaction, middle ear effusion (URI), otosclerosis
Chronic: chronic ear infection, trauma, otosclerosis
Sensioneural Hearing Loss
deterioration of the cochlea, loss of hair cells
Progressive, high frequency loss related to aging
Noise, head trauma, DM or other systemic diseases
Surfer’s ear.
Neural: CN 8 or auditory tract/cortex lesions; least common, Acoustic neuroma, MS, cerebrovascular disease
DX-Perform thorough PE including CN 8 testing, Weber/Rinne tests
TX- Refer unless cause is easily treated
Cold-Viral
Common Cold- 200 viruses cause
