Objective: Posterior auricular muscle response (PAMR) is a myogenic potential recorded over PAM after auditory stimulation. Its circuit is formed by cochlear and facial nerves with the generator in the brainstem. Here, we investigated whether the addition of a PAMR examination would add additional use in determining or localizing isolated brainstem lesions given that the importance of blink reflex (BR) in determining or localizing brainstem lesions is known. Our hypothesis was that examination of both reflexes would increase clinical utility.
