ENT · Ear and audiology: Bekesy audiometry

Sample item

On Bekesy automatic audiometry, the continuous tone tracing drops away sharply from the interrupted tone tracing within a short time and reaches the limit of the scale. Which Jerger type is this and what does it indicate?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Type III, retrocochlear lesion

In Bekesy audiometry, type I tracings overlap and are normal or conductive, while type II shows continuous tracing below the interrupted one at higher frequencies and indicates cochlear loss. Type III shows a rapid wide separation, indicating retrocochlear pathology such as vestibular schwannoma. Type IV is also seen in retrocochlear disease.

Option by option

  • A. Type I, normal hearing

    Type I shows overlapping tracings.

  • B. Type III, retrocochlear lesion (correct)

    Correct. Type III is characteristic of retrocochlear lesions.

  • C. Type IV, conductive loss

    Type IV is also a retrocochlear pattern, not conductive.

  • D. Type II, cochlear lesion

    Type II is cochlear, with a modest separation.
