Idiopathic sudden sensorineural hearing loss (ISSNHL) is an emergent disease in otologic field. Audiometric follow-up in patients with ISSNHL is important to assess the benefit of treatment and guide initiation of salvage treatment. However, there have been no report to guide the timing of follow-up. The objective of this study was to compare the recovery duration of patients who diagnosed as ISSNHL in each age group. A total of 150 subjects were included in this study and reviewed the medical and audiological records. According to ages, the subjects were classified into four groups; 0-19, 20-39, 40-59 years old and more than 60 years old. The period of time to final hearing levels was compared based on Siegel’s criteria. The period of time to final hearing levels was significantly different in patients with complete recovery based on Siegel’s criteria. 20-39 group (10.3 days) showed faster recovery than 0-19 (18 days), 40-59 (15 days) and ≥60 groups (23.4 days). The period of time to final hearing levels was not significantly different in patients with partial and slight recovery. Young adults with ISSNHL appear to recover faster than other age groups with ISSNHL. The result suggests that children and the elderly with ISSNHL need longer follow-up for hearing and young adults with refractory ISSNHL need earlier initiation of salvage treatment.
