The strict, formal definition of labirinthitis is a single, disabling attack of vertigo lsting 1 to 5 days accomapnie by sudden, permanent hearing loss in the affected ear. Using the strict definition, less than 5% of labyrinthitis patients ever experience a second attack, usually within 4 weeks of the first. Many doctors use a less-strict definition that sometimes seems to include any and all spontaneous vertigo with positive vestibular test results. the problem is that other disorders can "hide" within this less-strict definition, most commonly migraine and Meniere's.
