    • Position
    • shape
    • size
    • symmetry
    • color
    • lesions
    • drainage
  2. What are normal findings when inspecting the external ear?
    • Ears are aligned with eyes
    • ears are symmetrical
    • no redness, no lesions, no drainage
  3. palpation assessment of external ear
    • Assess tenderness and lesions
    • palpate tragus & mastoid process
    • pull helix forward b4 inserting otoscope
    • proceed carefully
  4. how should the otoscope exam of external ear be completed?
    • have pt tilt head to opposite side
    • use largest shortest speculum that will fit
    • pull pinna up and back for adult
    • pull pinna down and back for child
    • always look into the ear canal b4 inserting the otoscope
    • insert .5 in adult .25inches child
  5. what to look for during the external ear canal exam
    • color
    • drainage-cerumen in normal
    • patency
    • edema
    • lesions
    • foreign body
  6. scientific name for ear drum
    Tympanic Membrane
  7. assessment of tympanic membrane
    • note position of landmarks (cone od light)
    • ears are mirror images cone of light should be at 7 o'clock in right, 5 o'clock left
    • note intactness, lesions
    • color, and exudates.
  8. what should a normal tympanic membrane look like
    • pearly gray
    • intact (no tears, holes)
    • no lesions, or exudates
    • no bulging or retraction
  9. how do you check gross hearing
    use whispered voice test to assess for low pitch deficits (1-2 feet from ear)
  10. what test is used to check for bone conduction hearing?
    • Weber Test Place tuning fork on top of head.
    • sound should be heard equally thru both ears.
    • if it lateralizes, sound is heard better in impaired ear thru bone
  11. What test check bone conduction and air conduction
    • Rinne Test
    • place the tuning fork on the mastoid bone behind until no longer heard, then move it in front of the ear to see if hey can hear it.
  12. weber test results
    normal- the tuning fork is heard the same bilaterally

    abnormal- the sound of the tuning fork lateralizes. Sound is heard better in the impaired ear.
  13. Rinne Test results
    • normal- sound transmission through air is twice as long as through bone
    •  AC>BC
  14. what does the Romberg test check
    Romberg Test checks balance
  15. how do you perform the Romberg test
    • walk straight line
    • touch finger to tip of nose
    • stand still with eyes closed
