title: Laterality of sudden sensorineural hearing loss.
abstract: It is known that sudden sensorineural hearing loss and other otoneurologic diseases, such as tinnitus or Ménière disease, occur more frequently in the left ear than in the right. We studied lateralization of sudden deafness in 489 patients treated at Radebeul Hospital from January 2004 to December 2009. The male-to-female ratio was 1:1.24; we found a predominance of the left side only in female patients. The cause for this predominance is unclear. The slight asymmetry might indicate a greater vulnerability of the left inner ear in women, suggesting hormonal factors in the genesis of sudden deafness.
