PURPOSE: One of the etiologies for idiopathic sudden deafness is considered to be ischemia of the inner ear. Cryptogenic stroke is caused by a right-to-left shunt (RLS). The present study investigated whether RLS is associated with the occurrence of sudden deafness. METHODS: Contrast saline transcranial Doppler ultrasonography was performed to detect RLS. Subjects comprised 23 consecutive sudden deafness patients and 46 age- and gender-matched controls. Clinical characteristics, including vascular risk factors, were compared between sudden deafness and control groups. RESULTS: RLS was more frequent in the sudden deafness group than in controls (48 vs. 17%, p = 0.011). No significant differences in other clinical characteristics were seen between groups. CONCLUSION: RLS may be a potential cause of sudden deafness. Copyright 2008 S. Karger AG, Basel.
