Question

Can one have Tullio phenomenon without having hearing loss?

Answer

Absolutely, and there's a good study that has been published in 2002 by Russolo, who described a sort of "normal" Tullio, and how you can induce a sort of sway in normal subjects based on stimulus amplitude you deliver to an ear. This shows that Tullio can indeed occur independent of hearing loss as well. (Russolo, M. (2002). Sound-evoked postural responses in normal subjects. Acta Otolaryngology,122(1), 21-7.)

He had an electrophysiological assessment private practice in Colorado from 1987-2000, and he currently directs the Gallaudet Electrophysiology and Balance Center. He has done extensive research on vestibular evoked myogenic potential (VEMP) assessment of Deaf and hard-of-hearing subjects during his tenure at Gallaudet.

Menière Disease (MD) and Vestibular Migraine (VM) are the 2 most common causes of episodic vertigo. Diagnosis of both disorders is based on clinical history and on audiometric exam showing, in Menière Disease, sensorineural low-frequency hearing loss. At onset, differential diagnosis is often a puzzling dilemma, considering that around 50% of MD subjects also experience migraine, and VM patients, in many cases, report cochlear symptoms during attacks. Recent works propose that according to phenotypes and comorbidities, MD could be differentiated into subgroups, each presenting peculiarities for onset and evolution, MD with migraine among them. Other authors proposed a similar work for VM patients. In this webinar, Dr. R. Teggi examines clinical and etiological conditions commonly shared.
