Site Introduction

This site presents case studies in audiology, organized by the tabs to the right. They were obtained at another medical facility in the late 1990s. All air-conduction testing was conducted with TDH earphones rather than insert earphones.

The cases use problem-based learning strategies. Students are encouraged to research questions if the material has not yet been included in coursework.

The goals for this case study series are as follows:

* To reinforce masking concepts
* To provide experience at using immittance to identify middle ear pathology
* To allow students to classify multifrequency/multicomponent tympanograms using Vanhuyse classifications, determine abnormality
* To permit students to determine from the results if middle ear resonant frequency is raised or lowered, and if so, because of lack of/ additional stiffness and/or lack of and/or additional mass.

Cases were submitted by faculty, alumni and friends of the university. We thank all those who submitted the cases.

Use of these cases in other formats is permitted for teaching purposes; however, electronic posting of any cases to to publicly available sites is not allowed. Please give appropriate credit if utilizing cases in lecture materials, e.g.
