Case 2 Immittance

1. What is the meaning of a high peak compliance value on a 226 Hz Y tympanogram?  What pathology or pathologies are associated with this tympanometric abnormality?

2. What is the Vanhuyse labeling for the right 226 Hz tympanogram?  Is this a normal variant or would it be considered abnormal?

3.  What is the Liden/Jerger tympanogram type for the left ear?

4. Why do you think the audiologist did not conduct multicomponent tympanometry on the left ear?

5. What is the Vanhuyse labeling for the right 678 Hz tympanogram?  Is this a normal variant or would it be considered abnormal.

6. What is the resonant frequency, and what mass/stiffness factor is responsible?
