Case 11 Immittance

  • It is often difficulty to count the extrema, and in this case opinions may vary. What is the right ear Vanhuyse type at 226 Hz?  At 678 Hz?
  • What is the Liden/Jerger tympanogram type of the left ear?
  • Look at the ENT evaluation notes.  Why are both tympanogram findings consistent with the additional mass (and stiffness) of the middle ear effusion?
