Objective To investigate the association between initial audiogram patterns and prognosis in sudden deafness. Methods Clinical data of 339 patients with sudden deafness treated as in-patients were reviewed. The patients were divided into six groups based on their audiogram patterns: upward-sloping, downward-sloping, concave, flat, profound loss, and total deafness. Correlations between initial audiogram patterns and follow up outcomes were analyzed with rank sum tests, including Kruskal-Wallis Test and Mann-Whitney Test. Results Higher rates of hearing recovery was seen in patients with concave (83.8%) and upward-sloping (78.2%) audiogram patterns, compared to those with downward-sloping (46.2%) or flat (64.8%) audiogram patterns and those with profound hearing loss (57.1%). Patients with total deafness showed the worst hearing recovery rate (30.6%). Conclusion In patients with sudden hearing loss, total deafness at presentation indicates the worst prognosis, while upward-sloping and concave audiogram patterns suggest relatively favorable prognosis.%目的 探讨突发性聋患者治疗前听力图形状与预后的关系.方法 回顾性分析我科收治的339例突发性聋患者的临床资料.按患者治疗前听力图形状,分为上坡型,下坡型,凹陷型,平坦型,极重度聋型,全聋型六组.对突发性聋患者的治疗前听力图形状和预后的关系进行秩和检验分析,检验方法 有Kruskal-Wallis Test和Mann-Whitney Test.结果 经秩和检验分析,治疗前六组听力图形状和预后的差异有统计学意义.突发性聋患者听力图形状呈凹陷型和上坡型的预后较好,总有效率分别为83.8％和78.2％;听力图形状呈下坡型,平坦型,极重度聋型预后较差,总有效率分别为46.2％,64.8％和57.1％;全聋型预后最差,总有效率仅为30.6％.结论 突发性聋患者治疗前听力图形状为全聋型的预后最差,听力图形状为凹陷型和上坡型的预后较好.
