WHAT IS SUDDEN SENSORINEURAL HEARING LOSS?
Sudden Sensorineural Hearing Loss (SSNHL) is a medical emergency defined as an individual experiencing at least 30 dB (decibels) of sensorineural hearing loss occurring over a time period of three days or less. Sensorineural hearing loss occurs when there is damage to the inner ear cochlea (the organ of hearing) or to the nerve pathways to the brain.
