ENT · Vestibular disorders: ototoxicity monitoring

Sample item

A patient is starting cisplatin chemotherapy. Which audiometric test is most sensitive for detecting early ototoxic damage?

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

The answer and the reasoning

B. Extended high-frequency audiometry above 8 kHz

Cisplatin and aminoglycosides first damage the outer hair cells at the base of the cochlea, which affects the highest frequencies before the conventional speech range. Extended high-frequency audiometry detects this early. Speech tests in quiet and tuning forks are insensitive.

Option by option

  • A. Weber test

    The Weber test is a crude screening test.

  • B. Extended high-frequency audiometry above 8 kHz (correct)

    Correct. The basal turn is affected first, so high frequencies drop first.

  • C. Speech reception threshold in quiet

    Speech thresholds in quiet are normal until late.

  • D. Impedance audiometry

    Impedance audiometry assesses middle ear function.
