Acoustic Reflexes: Diagnostically Valuable but Clinically Under-utilized

---

1.  Which one of the following structures is NOT part of the acoustic stapedius reflex pathway? Cochlea 8th cranial (auditory) nerve 7th cranial (facial) nerve 5th cranial (trigeminal) nerve

2.  Measurement of acoustic reflexes can include up to how many stimulus conditions? 1 2 3 4

3.  Which one of the following is not an acoustic reflex measure with modern equipment? Threshold Amplitude Latency Phase

4.  Differentiation of normal hearing versus sensory (cochlear) hearing loss is most likely with acoustic reflex threshold measurement using which one of the following stimuli? Speech Broadband noise (BBN) Pure tones Electrical pulse

5.  Absence of ipsilateral and contralateral acoustic reflexes whenever the probe is in one ear and there is an abnormal tympanogram in the same ear is most consistent with: Middle ear dysfunction Severe cochlear hearing loss 8th nerve dysfunction Brainstem auditory dysfunction

6.  Absence of ipsilateral and contralateral acoustic reflexes whenever the stimulus sound is in one ear and there is a normal tympanogram in both ears is most consistent with: Middle ear dysfunction Severe cochlear hearing loss 7th nerve dysfunction Brainstem auditory dysfunction

7.  Absence of ipsilateral and contralateral acoustic reflexes in an infant with normal OAE findings is most consistent with: Otitis media Profound cochlear hearing loss Brainstem auditory dysfunction Auditory neuropathy spectrum disorder (ANSD)

8.  Which one of the following is NOT an evidence-based clinical application of acoustic reflexes? Detection of any degree middle ear dysfunction (along with tympanometry) Identification of 8th nerve dysfunction Validation of benefit from amplification Identification of possible brainstem auditory dysfunction

9.  Which one of the following is NOT a true statement about acoustic reflexes? Objective auditory measure Pathways include structures from middle ear to auditory brainstem Can be recorded with clinical instrumentation Requires patient attention and motivation

10.  Acoustic reflex measurement is not recommended for which one of the following patient populations? Hyperacusis Newborn infants Patients with possible false hearing loss Young children
