What Is an Auditory Brainstem Response (ABR) Test?
An ABR is a test which measures the speed of electrical impulses along the acoustic nerve from the inner ear to the brainstem. Frequently Asked Questions What is Electrocochleography (EcoG)? EcoG is a measure of the electrical potentials within the auditory system. As the auditory system is stimulated by an acoustic signal, it causes a change in the electrical potentials of the sensorineural mechanism that can be monitored through electrodes placed on the head and in the ears. This test is used to identify cochlear/endolymphatic hydrops for patients with dizziness. Frequently Asked Questions What is an Epley maneuver? An Epley maneuver, also known as canalith repositioning, is a therapeutic procedure which relieves symptoms for patients who have periods of brief spinning dizziness associated with position changes. These patients are identified as having benign paroxysmal positional vertigo (on the ENG) before this procedure is performed. Frequently Asked Questions What is a tympanogram
