22 Multiple choice questions

  1. conductive hearing loss
  2. -tympanic membrane perforation
    -tympanosclerosis aka myringosclerosis
    -otitits media
    -cholesteatoma
    -otosclerosis
    -ossicular disarticulation
    -Treacher Collins syndrome
  3. chronic otitits media
  4. separation (break) of ossicular chaing caused by trauma or disease
    -typically acquired
    -partial or complete
    -80% have erosion of incudo-stapedial joint (joining of incus and stapes)
  5. draine (with foul odor) from ear, earache
    -feeling of pressure, hearing loss
    -dizziness or facial muscle weakness
  6. -serous
    -suppurative, purulent
    -mucoid
  7. 1. autosomal dominant inheritance
    -1/2 are fresh mutations
    2. facial bone abnormalities
    -eyes
    -ears
    -underdevelped cheek bones, very small jaw
    -large mouth, w/ dental abnormalities
    -often w/ cleft palate
  8. single most common cause of serious hearing loss in young adulthood; not seen in children
    -1 in every 5 anglo women
    -half as common in Anglo men
    -1 in 100 African american
    -hereditary (dominant gene)
    -onset in 20s early 40s
  9. type fluid and time course
  10. -erossion of ossicles (fluid can break ossicles and erode middle wall)
    -erosion into labyrinth (fistula)
    -erosion and exposure of facial nerve
    -mastoiditis (before advent of antibiotics)
    -cloesteatoma
    -meningitis, encephalitis
  11. aka myringosclerosis
    -Calcium deposits formed on TM (sometimes ossicles), sometimes referred to as 'scarring' of the TM
    -Typically associated with chronic otitis or trauma to the TM
  12. -young childrenj
    -day care/multiple children living at home
    -hispanic, native american children
    -cleft palate (greater amount of fluid passes up into eustachian tube)
    -down syndrome
    -suppressed immune system
    -second-hand smoke
  13. -resolves naturally
    -antibiotics
    -pressure equalization/ventilation tubes
  14. 1. conductinve (combo of atresia and missing ossicles
    2. mild to moderate severe degree
    3.flat/rising configurtation
    3. inner ear structures typically normal; sensorineural present in rare cases
  15. surgical repair of TM
  16. surgical (stapedectomy) or hearing aids
  17. controlling otitis media, surgery for removal and middle-ear reconstruction
  18. benign 'pseudo tumor' arising from skin cells trapped in middle ear behind TM
    -can be acquired or congenital
  19. inflamation of the middle-ear space
    -secondary infection due to a cold
    -otitis media isn't contagious, but the cold is
  20. hardening of ear
    -formation of spongy bone deposits in middle ear
    -progressive, bilateral disease
    -produces impaired stapedial mobility and gradual conductive hearing loss
  21. -caused by trauma/ disease process
    -likely to cause hearing loss
    -most recover spontaneously w/in 2-3 months
    -surgical repair sometimes necessary
  22. genetic, sensorineural and otitis media
