Brain Stem Response

Persons with cerebellopontine angle tumors often have an increase in the latency of the acoustic reflex response that is comparable to the auditory brain stem response (ABR) in its sensitivity. However, reflex latency is less specific, since it may be prolonged in patients with Meniere's disease.

Brain Stem Response

Idiopathic facial nerve paralysis is believed by some to represent one aspect of a polyneuropathy. Conventional audiologic tests have not demonstrated involvement of the auditory portion of the eighth cranial nerve in this disorder. A case history is given of a patient with this disorder and an associated abnormal auditory brain stem response (ABR). Our study involved onetime evaluations of 17 patients with idiopathic facial nerve paralysis of varying durations. Each examination included clinical presentation and history, an audiogram, acoustic reflex, and ABR. Another patient had abnormal acoustic reflex test results (“unibox” pattern) suggestive of a brain stem lesion. On reexamination concurrent recovery of the paralysis and acoustic reflex was demonstrated. No auditory system disturbances secondary to the paralysis were detectable by ABR in this survey. The concurrent recovery of the “unibox” acoustic reflex and the facial paralysis suggests the association of a brain stem lesion with idiopathic facial nerve paralysis in this case.

Compound Action

Auditory brain stem response (ABR) is more commonly used to evaluate cochlear lesions than cochlear compound action potential (CAP). In a noise-induced cochlear damage model, we found that the reduced CAP and enhanced ABR caused the threshold difference. In a unilateral cochlear destruction model, a shadow curve of the ABR from the contralateral healthy ear masked the hearing loss in the destroyed ear.
