title: [Apraxia of the larynx].
abstract: Disturbances of vocal function in patients with apraxia of speech are well known in the literature and have often been described. Although apraxia of phonation is presumed, only 1 case is mentioned in the literature. We present a 51-year-old man (with missing signs of dysarthria and aphasia after spontaneous right temproparietal hemorrhagia) who had aphonia and missing respiration during speaking, whereas articulation was nearly undisturbed. After differential diagnostic exclusion of other central disorders of phonation we classify this patient as having apraxia of phonation or laryngeal apraxia.
