突發性耳聾預後因素之臨床分析

突發性耳聾的預後可能和初診時純音聽力圖型、初診時聽力閾值損失、延遲治療時間、耳鳴、眩暈症狀、上呼吸道感染等因素有關，但時有爭論。本文的目的是在回顧性分析突發性耳聾的預後因素，以便於臨床人員參考。個案收集自中山醫學大學附設醫院耳鼻喉科從89年12月到91年7月間突發性耳聾患者共77例，每個個案都有完整的病歷記載及純音聽力檢查。結果所有患者聽力損失之平均恢復率為56.21%，影響突發性耳聾恢復的預後因素只有初診純音聽力圖上4000Hz聽力閾值損失達到統計上顯著差異。至於年齡、性別、患側、發病季節、耳鳴、眩暈症狀、初診純音聽力圖型、初診聽力閾值損失；有無糖尿病、高血壓、上呼吸道感染及不同治療方式等因素均無統計學意義。
Prognosis of idiopathic sudden sensorineural hearing loss is related to various factors, such as types of initial audiogram, severity of pre-treatment hearing loss, time interval between onset of hearing loss to the start of treatment, simultaneous existence of tinnitus and vertigo. A retrospective study was performed by reviewing of a total of 77 patients who have been treated in the Department of Otolaryngology, Chung Shan Medical University Hospital, from December 1, 2000 to July 31, 2001. The overall recovery rate of hearing loss was 56.21%. It was found that pre-treatment hearing loss at 4000 Hz appeared to be a significant factor for a positive prognosis. However, there was no association between significant improvement of hearing loss and other factors evaluated in this study.
