摘要

背景：突發性耳聾目前尚無一特定有效的治療方式。本研究即針對類固醇和血管擴張劑的療效，以及一些可能影響預後的因素，作統計分析。
方法：經回溯性檢閱病歷，自1994年3月至1998年2月，搜集121例接受高劑量類固醇以及血管擴張劑治療之單側突發性耳聾患者。並以聽力進步程度（Recovery Magnitude）和聽力恢復率（Recov-ery rate）作為評估聽力恢復的指標。
結果：聽力進步平均為21.9 ± 21.7 dB，聽力恢復率平均為44.0% ± 62.6%。其中34名（28.1%）完全恢復，22名（18.2%）顯著改善，21名（17.4%）稍有改善，44名（36.4%）無反應。
結論：延遲治療時間愈短、初診聽障程度愈小、聽力圖上高頻率較低頻率損失程度小、及接受類固醇治療之患者，預後較佳。而其他因子，如血管擴張劑的治療、年齡、是否合併眩暈等，對聽力的恢復並無顯著影響。

BACKGROUND: The study aims at making an epidemiological survey of sudden deaf-ness to define the clinical characteristics of this disease. We focused on the treatment effect of steroid and vasodilator and some possible prognostic factors.
METHODS: 121 patients with unilateral sudden deafness who received high dose steroid and/or vasodilator-from Mar. 1994 to Feb. 1998 were reviewed retrospectively. Recovery magnitude and recovery rate were adopted as indexes of hearing recovery.
RESULTS: The average recovery magnitude and recovery rate were 21.9 ± 21.7 dB and 44.0% ± 62.6% respectively. There were 34 patients (28.1%) recovered completely, 22 (18.2%) with marked recovery, 21 (17.4%) with moderate recovery and 44 (36.4%) with-out significant improvement.
CONCLUSIONS: Good prognostic factors included: the shorter of the time elapsed from the onset of the symptom to the initiation of the treatment, less hearing impairment at the first visit, low-tone hearing loss on the audiogram and treatment with steroid. Other factors, however, didn’t influence the outcome significantly.
