“A 38-year-old male clerk saw his doctor because of sudden episodes of nausea and dizziness. These attacks had started 3 weeks earlier and seemed to be getting worse. The abnormal episodes at first lasted only a few minutes, during which “the room seemed to spin.” Lately, they had been lasting for many hours. A severe attack caused the patient to vomit and to hear abnormal sounds (ringing, buzzing, paper-rolling sounds) in the left ear. He thought that he was becoming deaf on that side.

The neurologic examination was within normal limits except for a slight sensorineural hearing loss in the left ear. Computed tomography (CT) examination of the head was unremarkable.”4



  • Chronic disorder of the peripheral vestibular and auditory systems (inner ear).

  • Auditory systems description

    • Complex series of interconnected tubes that are fluid-filled (fluid called endolymph) and form a labyrinth.

    • Peripheral vestibular sensory organs of each ear detect head position and head motion to provide input for gaze stability, orientation, and balance.

    • Peripheral auditory sensory organs of each ear convert sound vibration into a neural impulse to provide input for hearing.

    • Each system sends its respective sensory information, via the vestibulocochlear nerve (cranial nerve VIII), to the central nervous system for processing.

  • The pathophysiology of Ménière disease is not completely understood, however it is theorized that it is due to aberrant fluid homeostasis, which leads to overproduction of endolymph and distention of the membranous labyrinth.

  • Results in reports of severe relapsing and remitting episodes of rotary vertigo (illusion of spinning motion of the room or self) that can occur for minutes to hours.

  • Associated symptoms of fluctuating low-frequency sensory neural hearing loss, ear fullness, and tinnitus (ringing in the ear).
