Q

fever, ear pain (otalgia), ear pressure, hearing impairment,

Cause?

Treatment?

A

acute otitis media

Cause = viral (most common and RSV),
bacterial (strep pneuma, h influx, m cat)

Treatment = ABX = amoxicillin

  • remove risk factors (day care, 2nd hand smoke)
  • watchful waiting (if older kid no pain or fever)
  • myringotomy and tympanostomy = recurring case
