We administered the Chinese herbal medicine Hachimijiogan to 5 males, aged 60 years or older, who had grade2 or grade 3 idiopathic sudden sensorineural hearing loss without vertigo between 2019 and 2020. Three of thesefive cases healed or recovered. From 2015 to 2018, four males, aged 60 years or older, who had the same level ofidiopathic sensorineural hearing loss without dizziness visited. We did not administer Hachimijiogan to them. Oneof these four cases was cured.The thresholds observed while using the 5-frequency method at the first visit and the last visit of the Hachimijiogan-administered group were 58.2 ± 9.7 dB and 36.2 ± 14.2 dB, respectively, showing a significant improvement. On the other hand, the means of those thresholds observed in the nonadministered group were 49.2 ± 12.5dB and 50.2 ± 20.0 dB, respectively, and no significant improvement was observed.The degree of hearing improvement between the administered group and the nonadministered group was compared to the average threshold for hearing using the 5-frequency method at the first visit and the last visit. Thechange in the hearing threshold in the treated group was −22.0 (± 18.2) dB and the change in the nontreated groupwas 2.6 (± 13.3) dB. At P = 0.050044, there was no significant difference in the degree of improvement betweenthe two groups.
