Abstract:
The results of above 30 year research of pharyngeal phase of deglutition act in patients after classical and extended supraglottic laryngectomies and supracricoid laryngectomies are presented and compared with physiologic data. Initially roentgenocinematographic method has been used, computerized topokinetic analysis of acquired images was introduced later. With the latter method visualization of the deglutition act was better and the analysis more objective. The main purpose of the study was to find which functions and structures were spared after operations, that were necessary to facilitate pharyngeal phase of deglutition act and make it similar to physiologic act of deglutition.
