摘要

背景：一側突發性耳聾發作數年後，對側又再次發作者，謂之異側再發之突發性耳聾，在文獻報告上罕見。
方法：自1991年5月至1997年5月，6年間計7名病人，男女比例5:2。於住院期間每日予以聽力檢查，以評估病患改善之程度，並於門診追蹤聽力之變化。
結果：兩次發作之間隔平均為5年，有5/7的病人具有其他疾病之既往歷。發作時之聽力圖型不一，且預後不佳，八成以上之病耳聽力無變化。
結論：兩耳交替發作的突發性耳聾患者，多有既往歷。由於罕見，因此臨床表徵至為重要，有助於闡明本症的病態生理學，俾能給予有效的治療。

Background: Recurrent episode of sudden deafness over the opposite side after several years of the previous attack were noted and coined as ”contralateral recurrent sudden deafness”.
Methods: There were 7 cases experienced from May, 1991 to May, 1997. Five were men and two were women. Audiometry and nystagmography were performed everyday while admissions, and every 2 weeks for 3 months after discharge.
Results: The mean interval between two episodes were 5 years. Five of the 7 cases had systemic diseases in the past history. Poor prognosis was noted despite treatment.
Conclusions: Since contralateral recurrent sudden deafness is rare, detailed recording of clinical features become very much important, in order to elucidate its pathophysiology in the future.
