[Changes of the motility of the pillar in case of intrathoracical affections (author's transl)].

It is shown that in the light of relevant cases the intensified movements of the pillar and the vocal cords during the respiration can indicate a pulmonary or cardiac respiratory insufficience. The increased appearance of respiratory movements of the pillar after the stress of motion goes to prove a reduced cardiorespiratory efficiency. The unilateral or bilateral reduction of motility, the ataxy and tremor of the pillar as well as disturbances of coordination of the automatically steered respiratory movements of the pillar may indicate lesions of the distal, thoracical and abdominal vagus trunk by neoplasms and operative traumas, even if this damage was done far below the offset of the Rr. pharyngici. An interpretation of these retrograde losses of motility of the pillar is given, which is also important for understanding the median and intermediary position of the paralysed vocal cord.
