ears1 Flashcards
acute otitis media definition
inflammation of middle ear
acute otitis media bacterial pathogens
Streptococcus pneumoniae (most common)
Haemophilus influenzae
Moraxella catarrhalis
Occasional streptococcus or staphylococcus aureus
what is going on with the ear in otitis media
viral
Eustachian tube dysfunction or obstruction secondary to viral nasal pharyngitis – ineffective drainage of middle ear
what age group is most prone to otitis media
kids < 7 yrs
otitis media risk factors
Recent URI Congenital disorders – cleft palate, Down Syndrome Smoke Native American or Eskimo Family hx of otitis media
acute otitis media- history
Earache Fever Conductive hearing loss Otorrhea (if eardrum perforation) Perforated TM – intense pain followed by popping sound with acute relief Vertigo
acute otitis media PE
Bulging TM Distorted light reflex Obscured landmarks Decreased TM mobility Pneumonic otoscope Preauricular or cervical adenopathy Bullae on TM indicative of Mycoplasma Pneumoniae
acute otitis media Ddx
- Otitis Externa
- Referred pain from jaw, teeth
- Dental abscess
- Mastoiditis
- Ear canal furuncle
acute otitis media management/tx
- ATB
2. pain management
ATB for acute otitis media
- Amoxicillin 875 mg po q 12hours x 5-7 days
- Amoxicillin clavulanate for recurrence or No response to treatment after 48-72 hours
Combination oral antibiotics and topical otic suspension –for perforation (Ciprodex, Ofloxacin)
what med class to avoid with TM perforation
aminoglycosides
ex- gentamycin, streptomycin, tobramycin, neomycin
what pain meds for otitis media
acetaminophen
ibuprofen
topical local anesthetic- otitic solution
when to refer to ENT or consult MD for otitis media
- hearing loss after tx
- mastoiditis
- facial nerve palsy
- chronic perforation
- recurrent infection
perforated TM management
- often heals spontaneously
keep dry
ATB drops or systemic ATB
definition of serous otitis media
effusion in middle ear or chronic otitis media with effusion
what is happening with serous otitis media
patency of eustachian tube impaired preventing equalizing of pressure
serous otitis media is associated with
- Subacute infection
- Allergic manifestation
- Barotrauma
- Deviated septum
- Hypertrophic adenoids
- Benign or malignant neoplasms
serous otitis media - history
Diminished hearing
Popping sensation
Fullness in ear
Occasional dizziness
Often asymptomatic
serous otitis media- PE
Serous middle ear fluid (translucent membrane with diminished mobility)
Extensive inflammation and purulent middle ear effusion should not be evident
Air fluid level present (bubbles)
Decreased membrane mobility with insufflation
Conductive hearing loss
what will be seen with conductive hearing loss in serous otitis media
Weber – lateralize to affected side
Rinne BC>AC
dx testing / findings for serous otitis media
Audiometry – decreased hearing
Tympanometry – middle ear effusion
serous otitis media diff dx
- Acute Otitis Media
- Conductive hearing loss
- Meniere’s disease
serous otitis media management/tx
Topical decongestants – phenylephrine 1-2 sprays each nostril q8-12h for 3 days
Oral decongestants
can serous otitis media resolve sponatenously
yes, 2-3 weeks
patient education for serous otitis media
Valsalva or gum to relieve tube blockage
f/u for serous otitis media
in 4-6 wks
when to refer to MD with serous otitis media
persistent hearing loss
