A series of 238 patients with laryngeal paralysis seen during a six-year period (1976-1982) were studied with serial 16-mm motion picture filmstrips. There were 39 cases in which no etiological disease process could be found responsible for the paralysis; these were called "idiopathic." In all 39 cases, both the superior and recurrent laryngeal nerves were paralyzed indicating that the lesion involved the central (nuclear) lower motor neurons of the dorsal and ventral nucleus ambiguus. The high incidence of upper respiratory infections suggests a viral etiology in many cases. The ability to separate a pure recurrent from a combined superior and recurrent laryngeal paralysis on morphological indirect endoscopic appearance has significant diagnostic and therapeutic implications.
在六年期间（1976 - 1982年）对238例喉麻痹患者进行了研究，采用连续的16毫米电影胶片。有39例未发现可导致麻痹的病因性疾病过程；这些被称为“特发性”。在所有39例中，喉上神经和喉返神经均麻痹，表明病变累及疑核背核和腹核的中枢（核）下运动神经元。上呼吸道感染的高发病率提示在许多病例中病因是病毒。在形态学间接内镜表现上区分单纯喉返神经麻痹与喉上神经和喉返神经联合麻痹的能力具有重要的诊断和治疗意义。
