1969/70冬作者在维也纳医院见到不少喉返神经轻瘫患者,原因不明,曾诊断为特发性或隐原性麻痹。其发病率在9.77％至50％间(文献报告最低者仅1.32％)。作者认为应长期追随观察及查找病因,特发性喉返神经麻痹的发病率不会太高。作者探讨流感和喉返神经麻痹的关系,发现有些患者在声哑数周前确患流感。Zippel(1961)报告一例流感后4天出现Wallenberg氏综合征(一侧偏瘫),在血清内分离出流感病毒A_2型。但Tello和Tsetsaroky报告403例流感患者无一例声带麻痹。
In the winter of 1969/70, the author saw many patients with recurrent laryngeal nerve palsy in the Vienna Hospital. For unknown reasons, idiopathic or cryptogenic paralysis was diagnosed. The incidence rate of 9.77% to 50% (the lowest reported only 1.32%). The author believes that should be followed for a long time to observe and find the cause, the incidence of idiopathic recurrent laryngeal nerve paralysis will not be too high. The authors explored the relationship between flu and recurrent laryngeal nerve paralysis and found that some patients had a flu some weeks ago. Zippel (1961) reported Wallenberg’s syndrome (hemiparesis on one side) four days after the flu was reported, and influenza A 2 was isolated in the serum. But Tello and Tsetsaroky reported 403 cases of influenza patients without vocal cord paralysis.
