ENT · Hearing rehabilitation: CROS aid

Sample item

A patient has a profound unilateral sensorineural loss with normal hearing in the other ear. Which aid picks up sound on the deaf side and transmits it to the good ear?

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

The answer and the reasoning

A. CROS hearing aid

A CROS (contralateral routing of signals) system places a microphone on the deaf ear and sends the signal to a receiver on the better ear, helping with the head shadow effect. Bone conduction devices are an alternative.

Option by option

  • A. CROS hearing aid (correct)

    Correct. CROS reroutes sound to the better ear.

  • B. Hearing loop alone

    A hearing loop does not address single-sided deafness.

  • C. Conventional bilateral aid

    A conventional aid on a dead ear gives no benefit.

  • D. Brainstem implant

    A brainstem implant is for absent cochlear nerves.
