what the risks are eng, electronystagmography records involuntary eye movements, test is used, whether ear nerve damage, cause of dizziness, vertigo, nerve, the inner ear is one, the more common causes, vertigo, metal electrodes, similar to those used, ecg, smaller, side, below each eye, attached by adhesive, by a band around the head, a "ground" electrode is attached, forehead, electrodes record eye movements relative, position, the ground electrode, a standard caloric stimulation test is performed, cold, hot water instilled, ear canal, each ear is tested separately, duration, velocity, speed, eye movements that occur, the inner ear is stimulated, recorded by the electrodes, test takes, 90 minutes, audiologist, interpreted, ent specialist, no preparation, check, taking any medications, infants, children, test depends on child's age, prepare child, infant test, procedure preparation, birth to 1 year, toddler test, procedure preparation, 1 to 3 years, preschooler test, procedure preparation, 3 to 6 years, schoolage test, procedure preparation, 6 to 12 years, adolescent test, procedure preparation, 12 to 18 years, there is minimal discomfort, find cold water, in the ear uncomfortable, brief vertigo, this test is used, ear nerve damage, cause of dizziness, vertigo, vestibular portion, the acoustic nerve, nerve, the inner ear, the more common causes, vertigo, electronystagmography is performed to evaluate the acoustic nerve, provides hearing, helps, balance, test recommended, the person is experiencing dizziness, vertigo, impaired hearing, suspected toxicity from certain antibiotics, psychologic causes, vertigo, suspected, electronystagmography provides exact measurements of eye movements rather than the objective observation of standard caloric stimulation, record behind closed eyelids, the head, variety of positions, distinct involuntary eye movements should occur after instillation of cold, hot water, ear canal, expected eye movements, not occur, some damage, nerve, the inner ear, injury that damages the acoustic nerve, cause vertigo, congenital disorders, trauma, rubella, blood vessel disorders, hemorrhage, bleeding, clots, atherosclerosis, the blood supply, the ear, cholesteatoma, ear tumors, poisons, medications, toxic, ear nerves, aminoglycoside antibiotics, antimalarial drugs, loop diuretics, salicylates, additional conditions under which the test performed, acoustic neuroma, benign positional vertigo, labyrinthitis, meniere's disease a risk is associated, the caloric stimulation part, excessive water pressure, injure a previously damaged eardrum, rarely occurs, caloric stimulation should not be performed, eardrum has been perforated, the risk of causing ear infection this test, adjunct to a caloric stimulation test.
