A close case history determined that the dizziness was evoked by loud sounds (Tullio phenomenon) and the oscillopsia was related to intense exertion.
The investigated parameters included spontaneous nystagmus, head-shaking nystagmus, positional nystagmus during the Dix-Hallpike and head-roll maneuvers, nystagmus with the Valsalva maneuver, the Tullio phenomenon after hyperventilation and exposure to 3 kHz at 110 dB, and eye movements after mastoid vibration at 100 Hz.
The physiologic underpinnings of the Tullio phenomenon were first described in 1929, when Tullio noted that experimentally induced fenestrations in the bony capsule of the lateral semicircular canals of pigeons caused the canals to be sound-responsive, inducing vestibular activation (11,12).
The Tullio phenomenon is seen in a range of clinical contexts, including congenital deafness, Meniere disease, suppurative middle ear disease, and spirochetal infections, such as syphilis or Lyme disease.
An otic capsule dehiscence opens up a third window into the inner ear, and clinical findings such as a low-frequency bone conduction hearing loss, dizziness, vertigo, or Tullio phenomenon have been reported [2,7].
