Methods A total of 106 cases of low-frequency descending sudden hearing loss meeting the inclusion criteria were collected. The correlation between gender, age, side, course of the disease, concomitant symptoms, degree of hearing loss and therapeutic effect were analyzed. Results The total effective rate of low-frequency descending sudden hearing loss was 79%. The total effective rate was higher in patients aged ≤30 years old(91%, 31/34), compared to patients between 31 and 45 years old(80%, 37/46)and between 46 and 68 years old(61%, 16/26). The difference was statistically significant(p<0.05). Patients with a course ≤7 days(95%, 52/55)had a better prognosis than those with a course > 7 days(63%, 32/51), with this having a statistically significant difference(p<0.001). The therapeutic effect of patients with ear fullness(88%, 53/60)was better than those without ear fullness(37%, 31/46), and this difference was statistically significant(p<0.05).There was no statistically significant difference in the total effective rate between genders, incidence sides, whether they had tinnitus, or mild or moderate hearing loss(p>0.05). Conclusion The prognosis of low-frequency descending sudden hearing loss without vertigo is related to age, course of the disease, ear fullness, and initial hearing levels. Young age, a short course of the disease and ear fullness are positive factors for a good prognosis of low-frequency descending sudden hearing loss without vertigo.
