A 47-year-old patient reported, “I have been able to hear my eye movements in my left ear for 3 years. When I sneeze I get a short attack of vertigo.” When vibration sense was tested by tuning fork (placing it on the sternum and medial malleolus), the patient heard the sound in his left ear indicative of autophony, typical for superior canal dehiscence syndrome. Diagnosis was proven by fistula tests, vestibular evoked myogenic potentials,1 and CT scan2 (supplementary material). Testing vibration sense can contribute to the diagnosis of vertigo and detection of the affected ear.
