The following patients were excluded from the study: those who (1) complained of bilateral acute hearing loss; (2) did not complain of dizziness or ipsilateral tinnitus as an accompanying symptom; (3) refused to answer the questionnaires; (4) had a history of trauma in the ipsilateral temporal area; (5) had abnormal physical findings in the ipsilateral ear (otitis media, otitis externa, or perforation of the tympanic membrane); (6) had a retrolabyrinthine lesion detected by radiological evaluation (vestibular schwannoma, etc.
To detect retrolabyrinthine lesions, subjects who complained of dizziness underwent auditory brainstem response measurement, video nystagmography, smooth pursuit test, optokinetic nystagmus, and optokinetic after-nystagmus tests at the Hearing and Balance Center of Korea University Ansan Hospital.
