大剂量全身类固醇治疗是突发感音神经性听力损失（SSNHL）的主要治疗方法。 SSNHL 范围的恢复率约为 47-63%，并受到各种预后因素的影响。为了评估特定临床参数的预后价值，我们通过临床和统计分析回顾了 289 例病例。本研究纳入了2005年1月至2012年12月就诊于顺天乡大学医院耳鼻喉科的289名SSNHL患者。根据临床图表对这些病例进行回顾性分析。根据纯音听力图结果、SSNHL 发病与初始治疗时间之间的持续时间、季节性发病率、头晕、患者年龄、听力损失程度、初始纯音听力图模式和潜在疾病的存在来评估听力改善情况。 289 名患者中有 196 名（67.8%）的听力得到改善；大多数患者的这种改善在 7 天内就开始出现，随后听力迅速恢复。 14天内未能出现改善的病例不太可能实现听力恢复。早期听力损失越严重，听力恢复率越低。与 60 岁以上的患者相比，60 岁以下的患者听力改善的预后似乎更好。 SSNHL 患者康复的重要预后因素包括症状出现后开始治疗的时间、早期听力损失的程度以及受影响患者的年龄。
High-dose systemic steroid therapy is the mainstay treatment for sudden sensorineural hearing loss (SSNHL). Recovery rates from SSNHL range are about 47-63% and are influenced by various prognostic factors. To evaluate the prognostic value of specific clinical parameters, we reviewed 289 cases by clinical and statistical analysis. This study included 289 patients with SSNHL who visited the Department of Otolaryngology at Soonchunhyang University Hospital from January 2005 to December 2012. The cases were reviewed retrospectively based on clinical charts. Hearing improvement was evaluated in relation to pure-tone audiogram results, duration between SSNHL onset and time of initial treatment, seasonal incidence, dizziness, patient age, degree of hearing loss, patterns of initial pure-tone audiogram and presence of underlying disease. Hearing improvement was observed in 196 of 289 (67.8%) patients; such improvement began within 7 days in most patients, followed by rapid hearing recovery. Cases that failed to show improvement within 14 days were unlikely to achieve hearing recovery. The more severe the hearing loss during the early stage, the lower the hearing recovery rates. Patients aged less than 60 years appear to have better prognosis of hearing improvement compared to those who are over 60 years. Important prognostic factors for recovery in patients with SSNHL include the time of initiating treatment after symptom onset, the degree of early-stage hearing loss, and the age of the affected patient.
