Quiz: Immittance & OAE Flashcards
What could cause the ear canal of a young infant to collapse?
negative pressure
Why is wideband tympanometry often considered easier for children than traditional 226 Hz tympanometry?
Because it measures different frequencies simultaneously
Because it uses quieter probe tone which is less startling for them
What differences exist in OAE levels between newborns and adults?
DPOAEs are higher in newborns compared to adults.
How does middle ear affect OAEs?
ME conditions can affect OAEs
How do shorter ear canals in young children affect the volume and resonance frequency compared to adults?
Smaller volume, higher resonance frequency
The pediatric ear canal is more ________ than the adult ear canal.
compliant
A healthy middle ear system of an infant (< 6 months old) is____________.
mass dominated
What ECV would you expect to find in a clogged PE tube?
normal ECV
What ECV would you expect to find in patent PE tube?
large ECV
You have an uncooperative child with bilateral middle ear dysfunction. How can you shorten the testing time without compromising the diagnostic value of acoustic reflex testing? What would be your first choice of stimulus to use?
BBN
Wideband tympanometry cannot be used with infants?
false
What should you consider when evaluating the quality of a WB measurement?
The 3D graph
The wideband average graph
The absorbance graph
Having a variety of toys and methods to distract or engage children is very useful. How can the Wideband Tympanometry system be utilized to help keep the child engaged during the test?
Drawing a “rainbow” by showing the child the 3D graph developing on screen
Wideband Tympanometry is particularly useful for children under 4-6 months old because ______________.
It takes measurements at multiple frequencies, avoiding the need to choose between 226Hz and 1000Hz probe tones
What does WB tympanometry absorbance measure?
The amount of energy that is absorbed by the middle ear
