The performed analysis covers the physiology of the pharyngeal phase of deglutition in 11 patients aged 45-65 years. The studies were carried out with the aid of roentgenocinematographic examinations (RTGC) and after preparing an adequate computer program, a computer topokinetic analysis was accomplished (CTA). The measurement of parameters established in CTA make it possible to obtain the image of the pathway passed by the anatomical structures, the dynamics, the shape and the relative distances of two anatomical structures, with the duration of the deglutition act being taken into consideration. The use of RTGC images in CTA allows for better understanding of the mechanism acting in the pharyngeal phase of deglutition act in physiological conditions.
