electronystagmogram

electronystagmogram

 [e-lek″tro-nis-tag´mo-gram]
1. the record obtained by electronystagmography.
2. a test done using electronystagmography, assessing the balance mechanism of the inner ear. It involves running a cool liquid and then a warm liquid through a tube within the ear canal; the change in temperature stimulates the inner ear, which in turn causes rapid reflex eye movements. The movements are recorded, yielding information about the functioning of the balance mechanism.

There was no significant effect on parameters of rotatory movement-induced electronystagmogram in rabbits after intravenous injection of ginger juice (Qian and Liu, 1992).
Some examples of diagnostic tests the otolaryngologist may request are a hearing examination, blood tests, an electronystagmogram (ENG--a test of the vestibular system), or imaging studies of the head and brain.
Finally, we rarely have a pre-event audiogram or electronystagmogram that serves as a baseline, and most of our offices are not equipped for air caloric, closed-loop caloric, or rotational-chair testing.
We obtained baseline audiograms and electronystagmograms. To simulate the conditions under which our patients had experienced inadvertent ototoxicity, our patients with Meniere's disease had ventilation tubes inserted that were placed into the posteroinferior quadrant of the tympanic membrane in the affected ear.
As to caloric test-induced electronystagmograms, there were 30 bilaterally normal cases (75.0%), one case of left-side semicircular canal paresis (25%) and nine cases of bilateral semicircular canal paresis (22.5%).
