The therapeutic effects of neurotropin (NSP) on sudden deafness were compared with those of usual therapy (steroid) from January until December, 1987. We defined the improvement for patients over 50 years old and with a 20-50 dB hearing level on first medical examination in NSP. Of the 78 cases given this therapy complete recovery was seen in 40 cases, and marked recovery and mild recovery in 6 cases each. Improved rate was 78.0% in NSP therapy and 53.1% in steroid therapy.doi:10.5631/jibirinsuppl1986.1991.supplement48_34 fatcat:e3pnm2kufrgvxaxfqq6y4m77fi
