Schmidt syndrome due to idiopathic accessory nerve paralysis.
A patient with Schmidt syndrome due to idiopathic accessory neuropathy has had paralysis of soft palate and larynx as well as trapezius and sternocleidomastoid muscles, reflecting involvement of cranial and spinal roots, respectively. In addition to vocal cord paralysis on the laryngoscopy, videofluoroscopy confirmed diminished mobility of the soft palate. Electrodiagnosis showed accessory neuropathy at the proximal segment. Furthermore, the accessory nerve innervated not only upper but also middle and lower portions of the trapezius muscles.
