A novel audiogram model for predicting the prognosis of sudden sensorineural hearing loss.

ABSTRACT:

Background

Sudden sensorineural hearing loss (SSNHL) is an otological emergency involving hearing loss greater than 30 dB across three consecutive frequencies within 72 hours. Prognosis is influenced by the initial pure-tone audiogram (PTA), with ascending and U-shaped patterns showing better outcomes and descending patterns linked to poorer outcomes. Traditional audiograms are classified into four to seven types based on hearing thresholds at four to six frequencies, such as flat, ascending, or descending types. However, the definitions of these patterns are often ambiguous and not easy to apply in clinical practice. This study aimed to compare the prognostic value of the traditional seven-type audiogram model with a novel three-type audiogram model.
