Background and Aims : There are many known prognostic factors such as patients's age, treatment onset, initial hearing threshold, and dizziness. This study was aimed to collect the clinical features and the prognostic factors of sudden
sensorineural
hearing loss with or without dizziness. Materials and Methods : We reviewed the chart of 246 patients who were diagnosed as idiopathic sudden sensorineural hearing loss and treated from October 1995 through December 1999. Results : The number of
patients who had complaint of dizziness was 105 out of 253. Among many factors, age, treatment onset, initial hearing threshold, and dizziness showed statistically significant correlation with the final result of hearing recovery. We analyzed the
correlation between improved and no improved group, dizziness had no meaning as a prognostic factor any more without initial hearing threshold. Conclusion : We can predict hearing outcome of sudden sensorineural hearing loss more accurately on
the
basis
of age, delayed time before treatment, initial hearing level, dizziness. But dizziness may not be an independent prognostic factor without considering initial hearing level.
