Vestibular Migraine and Tinnitus: A Challenging Narrative.

Vestibular migraine (VM) is one of the most common types of episodic vertigo. Over the last 11 years, this disorder has been studied by both neurologists and otolaryngologists. Based on the clinical symptoms and previous migraine history, the Barany Society and the International Classification of Headache Disorders have created the diagnostic criteria for VM. Unilateral and pulsatile headache, phonophobia, photophobia, auras, and a previous history of migraine have been included in these criteria. Although these symptoms are common and widely known, other symptoms not included in the Barany Society criteria are emerging and have been described in some clinical studies. These emerging criteria include audio-vestibular symptoms such as hearing loss, ear fullness, and tinnitus. Ringing ears could be associated with other vestibular disorders such as superior canal dehiscence and Ménière's disease, but not in VM. The frequency, pathophysiological contributors, and clinical characteristics of this symptom in individuals with VM will be explored in this review.
