Background & Objective : Sudden Sensorineural Hearing Loss(SSNHL) is a medical emergency defined as an individual experiencing at least 30 dB (decibels) of SSNHL occurring over a time period of three days or less.
Pure tone audiometry is by far the most widely used to diagnose SSNHL. Besides Auditory steady-state response(ASSR) is also generally accepted to predict hearing of SSNHL patients objectively & effectively.
In this study, we analyzed correlation between ASSR and PTA in SSNHL patients, comparison with non-SSNHL, and study clinical usefullness of correlation between ASSR and PTA to forecast prognosis of SSNHL.
Patients & Methods : We retrospectively analyzed chart of SSNHL patients who visited department of Otolaryngology at Chonnam National University Hospital from January 2011 to June 2013, and underwent ASSR and PTA. The whole patient group was comprised of 30 men and 32 women. The mean age was 43.1 years. A control groups consisted of non-SSNHL patients non-SSNHL who visited department of Otolaryngology at Chonnam National University Hospital in same periods.
Results : There was a very strong positive linear correlation between average hearing threshold of ASSR and PTA(correlation coefficient=0.865) among non-SSNHL patients. Furethermore there was relatively strong positive linear correlation between average hearing threshold of ASSR and PTA(correlation coefficient=0.576) among SSNHL patients. And there was nomal positve linear correlation between average hearing threshold of ABR and PTA(correlation coefficient=0.327) among SSNHL patients.
Average gap between ASSR and PTA among SSNHL was 4.19. it was statistically significant reduction compared with non-SSNHL (p=0.0097)
Conclusion : There was a strong correlation with average hearing threshold of ASSR and PTA among non-SSNHL & SSNHL patients. In comparison to ABR, ASSR was more correlate to PTA among SSNHL patients. So we concluded that ASSR can be a usefull diagnostic tool in SSNHL.
Average gap between ASSR and PTA had statistically significant difference between non-SSNHL and SSNHL patients. so we are required to study more in this gap.
