This study compared sudden deafness (SD) cases in 20-year age bands to investigate their causes and treatment outcome.
Retrospective study.
178 unilateral SD patients were divided into four 20-year age-groups, namely Groups I (aged 0-19 years, n = 6), II (aged 20-39 years, n = 33), III (aged 40-59 years, n = 63), and IV (aged 60-79 years, n = 76).
An inner ear test battery and/or serology assay were performed.
Incidence of SD in relation to overall neurotological cases did not significantly differ among the four groups. Groups I and II showed two or three audiographic patterns, while Groups III and IV had six audiographic patterns indicating that the aetiology of Groups I and II may be of the same origin, while Groups III and IV had multiple aetiologies. The hearing improvement rate was significantly higher in Groups III (62%) and IV (62%) than in Groups I (16%) and II (33%).
SD inevitably affects individuals of all ages. Significant differences in the audiographic patterns and speculative causes may account for various outcomes of treatment in each 20-year age band. Those SD patients aged 40-59 and 60-79 years showed significantly better treatment outcomes than those aged 0-19 and 20-39 years.
本研究比较了各 20 岁年龄组的突发性聋（SD）病例，以探讨其病因和治疗结果。
回顾性研究。
178 例单侧 SD 患者分为 4 个 20 岁年龄组，即 I 组（0-19 岁，n=6）、II 组（20-39 岁，n=33）、III 组（40-59 岁，n=63）和 IV 组（60-79 岁，n=76）。
进行内耳测试和/或血清学检测。
4 组中 SD 的发病率与所有神经耳科学病例相比无显著差异。I 组和 II 组显示出两种或三种听力图模式，而 III 组和 IV 组则显示出六种听力图模式，这表明 I 组和 II 组的病因可能具有相同的起源，而 III 组和 IV 组则具有多种病因。III 组（62%）和 IV 组（62%）的听力改善率明显高于 I 组（16%）和 II 组（33%）。
SD 不可避免地影响各个年龄段的个体。听力图模式和推测病因的显著差异可能导致每个 20 岁年龄组的治疗结果不同。40-59 岁和 60-79 岁的 SD 患者的治疗效果明显好于 0-19 岁和 20-39 岁的患者。
