  1. characteristics otitis media
    • 1/4 of children have this
    • secondary disease caused by eustachian tube not the ear
    • 99% of ppl with cleft palate have this
  2. otitis media steps
    • 1 - URI / blocked tube - air cannot get out
    • 2 - fluid build up - causes blockage, negative pressure, sterile fluid which is bacteria heaven
    • 3 - infection - bacteria get in and breed, immune system kills it and creates puss, puss pushes on ear drum and hurt extremely bad
    • 4 - perforation - ear drum breaks, puss releases
    • 5 - TM heals and repeats?
  3. otitis media is caused
    because E-tubes are immature
  4. why are antibiotics not used
    because they stop the process in the middle and leave build up in the middle ear - not good
  5. classification by pathology
    • purulent / suppurative - ear full of infection
    • nonpurulent / nonsuppurative - ear full of sterile fluid
  6. classification by fluid
    • serous - wet, watery fluid
    • secretory / mucoid - thick, goey puss, long term
  7. classification by time
    • Acute (AOM) - happening now
    • Recurrent - typical case - cycles between well and sick
    • Chronic (COME) - one case of OM that lasts longer than 3 months
  8. E in COME
    • Chronic Otitis Media Efusion
    • efusion - leaking fluid
    • like soliders in WWII
  9. treatment of otitis media 7
    • antibiotics / decongestants
    • inflation
    • myringotomy
    • PE tubes
    • myringplasty
    • T & A
    • mastoidectomy
  10. antibiotics / decongestants
    not a real treatment ( not used unless E-tube needs to be unblocked or in extreme cases)
  11. inflation
    • mechanically blowing open the E-tube
    • great for adults, but not for children because it will only be temporary
  12. myringotomy
    • to cut the ear drum
    • puss under pressure = lance it (cut it)
    • it is better to make a nice incision than to let it rupture
  13. PE tubes 6
    • pressure equilization tubes
    • not drainage tube
    • put in and wait until E tubes mature
    • must do a myringotomy first
    • ear will force them out in 6 months to a year - normal
    • done in doctors office
  14. myringplasty
    • used in chronic comdition
    • takes part of own issue and uses it to cover the permanent hole
    • must check to make sure that E-tube works first
  15. T & A
    • tonsil actomy
    • they can be removed if it is ausing E-tube dysfunction
  16. mastiodectomy
    • only in very serious cases
    • take mastoid bone out if it is infected because it can lead to sull and brain infection
    • cutting it out leads to a permanent conductive hearing loss
  17. complications of otitis media
    • perforation of the TM - whole in TM
    • mastoiditis - infection of mastoid
    • glue ear - pulling ot white cement
    • cholesteatoma
