Exam Preview for 40725: Beyond Type A, B, and C: Normalizing Mass,

Beyond Type A, B, and C: Normalizing Mass, Friction, and Stiffness-Dominated Language in Wideband Tympanometry Middle Ear Assessment

Please note: exam questions are subject to change.

1. In a stiffness-dominated middle ear system, which frequency range typically shows reduced energy transmission? High frequencies Low frequencies Mid frequencies All frequencies equally
2. Which wideband tympanometry finding is most consistent with otosclerosis? High absorbance at low frequencies Reduced absorbance at low frequencies Flat absorbance across all frequencies Increased absorbance at high frequencies
3. A WBT absorbance curve shows reduced transmission at high frequencies with normal low-frequency absorbance. This pattern suggests what? Stiffness-dominated system Mass-dominated system Friction-dominated system Normal middle ear function
4. What is the primary benefit of using mass/stiffness-dominated language over traditional tympanogram classifications? Simplifies patient explanation Enhances communication and diagnosis accuracy with ENTs Replaces the need for tympanometry Requires less technical knowledge
5. A patient presents with cholesteatoma. What WBT pattern would likely be observed? Elevated absorbance at mid frequencies Reduced absorbance at high frequencies, indicating mass-dominated system Reduced absorbance at low frequencies, indicating stiffness-dominated system Normal absorbance across all frequencies
