45 True/False questions

  1. Purpose of the Visual Otoscopic Inspection?NOT to diagnose a disorder, but to assess the outer ear and TM and middle ear for something obviously atypical
    (can assist in interpreting other audiological evaluation results)

          

  2. Type C Tymp. reflects...eustachian tube dysfunction.
    -non-specific finding
    -may reflect oncoming of otitis media

          

  3. The Tympanic Membrane vibrates most easily when air pressure is...the probe tone is constantly on and the Microphone can measure how much sound is absorbed/admitted, and how much is reflected into the ear canal

          

  4. To interpret Type B tympanogram...flat. no peak (abnormal shape)
    very low admittance; so little or no mobility

          

  5. Type C Tympanogramflat. no peak (abnormal shape)
    very low admittance; so little or no mobility

          

  6. Ear Canal Volume.6 to 2.5 ml
    -depends on age, gender, body size, etc

          

  7. Negative Peak Pressureless than -150 daPa

          

  8. Type Asnormal middle ear function
    normal shape, peak pressure and peak admittance

          

  9. Immittance Testing-Purposesthis term reflects what the test measures; combination of the words "impedance" and "admittance"

          

  10. Tympanometry determines the...peak admittance (sometimes static compliance)
    physical volume (aka ear canal volume)
    peak pressure

          

  11. Normal tympanometry indicates normal...indicates normal middle ear function, NOT normal hearing

          

  12. when there is negative peak pressure, this means...less than -150 daPa

          

  13. A type B tymp with a physical volume that is too small means...the TM is not intact

          

  14. Tympanometry may not be accurate with children younger than...7 months

          

  15. Type Adnormal middle ear function
    normal shape, peak pressure and peak admittance

          

  16. Admittancethis term reflects what the test measures; combination of the words "impedance" and "admittance"

          

  17. Obviously atypical things to look for in the Otoscopic Inspectionstructural defect of the ear, head or neck
    ear canal abnormalities
    tympanic membrane abnormalities

          

  18. when is the visual otoscopic inspection performed?before tympanometry

          

  19. Peak pressure is shown by...relative to the air pressure in the middle ear

          

  20. Describing tympanic membrane abnormalities for results of the Otoscopic InspectionBlood or effusion (drainage)
    inflammation
    excessive cerumen or foreign object

          

  21. A too large ear canal volume usually means...the tympanic membrane is not intact (so it picks up the volume of the middle ear too)

          

  22. normal peak admittanceless than 0.3 ml
    -reflects stiffness of the middle ear system.

          

  23. Impedance:opposition to flow of acoustic energy at the middle ear

          

  24. **need to know Peak Admittance ranges0.3 ml - 2.0 ml

          

  25. A type B tymp with Normal physical volume often reflects...the TM is not intact

          

  26. In tympanometry, the microphone can measure...the probe tone is constantly on and the Microphone can measure how much sound is absorbed/admitted, and how much is reflected into the ear canal

          

  27. Immitanceacoustic energy passed by the tympanic membrane into the middle ear

          

  28. Type Aexcessively middle ear system
    normal shape, peak pressure, HIGH peak admittance: >2.5 ml
    d: deep

          

  29. Normal Peak Pressureless than -150 daPa

          

  30. In a normal middle ear, the greatest admittance is at ____, and declines as the air pressure0 daPa.
    admittance (passing of acoustic energy) declines as the air pressure moves away from 0, either positively or negatively.

          

  31. A type B tymp with a physical volume that is too large means...the TM is not intact
