IHS Auditory Assessment 5

Question 1

A patient presents with normal hearing thresholds but reports difficulty understanding speech in noise. Which test battery is most appropriate to investigate auditory processing?

Accepted Answer

Dichotic listening, temporal processing, and binaural interaction tests

Answer

Central auditory processing disorders (CAPD) are evaluated with dichotic listening tasks, temporal processing measures (e.g., gaps-in-noise), and binaural interaction tests, as peripheral hearing is typically normal.

Question 2

Which condition is characterized by a low-frequency sensorineural hearing loss that fluctuates, accompanied by aural fullness, tinnitus, and vertigo?

Accepted Answer

Ménière's disease

Answer

Ménière's disease presents with the classic tetrad of fluctuating low-frequency SNHL, episodic vertigo, tinnitus, and aural fullness due to endolymphatic hydrops.

Question 3

The 'shadow curve' during pure-tone audiometry occurs when:

Accepted Answer

The test signal crosses over to the non-test ear and produces a response

Answer

A shadow curve appears when sound from the test ear crosses over (via bone conduction) to the better non-test ear, creating the false impression that the poorer ear has some residual hearing.

Question 4

In the modified Hughson-Westlake procedure, a threshold is defined as the lowest level at which a patient correctly responds in:

Accepted Answer

2 out of 3 ascending presentations at the same level

Answer

Using the modified Hughson-Westlake method, threshold is the lowest hearing level at which the patient responds correctly to at least 2 out of 3 ascending presentations.

Question 5

Absent distortion product OAEs (DPOAEs) with normal ABR thresholds most likely suggests:

Accepted Answer

Outer hair cell dysfunction with intact auditory nerve function

Answer

Absent DPOAEs indicate outer hair cell dysfunction, while a normal ABR confirms that the auditory nerve and brainstem pathways are intact, suggesting isolated OHC damage.
