[Research on the prognosis and efficacy criteria of sudden sensorineural hearing loss].

Sudden sensorineural hearing loss is a common and frequently-occurring disease. Looking at the efficacy evaluation of the diagnosis and treatment of sudden sensorineural hearing loss at home and abroad, each country has its own characteristics in the indicators and criteria of the treatment efficacy evaluation, and the common indicators of efficacy evaluation include: average pure-tone hearing threshold, the absolute value of hearing improvement of impaired frequency, the percentage of average pure-tone hearing threshold increase, speech discrimination score, speech recognition threshold, etc. The evaluation criteria mostly take the efficacy grade or the improvement level of average hearing threshold as the criterion of effective treatment, and the lack of unified standards is not conducive to the homogenization of global research related to sudden sensorineural hearing loss.
