[Objective evaluation of the influence of the hyoid bone resection on the disorders in the act of swallowing].
Laryngographic, manometric and videorentgenocinematographic examinations of swallowing were conducted on 49 patients after partial laryngectomy and on 35 subjects being a control group. The results of examinations indicate that the mobility of remaining after the surgery parts of the larynx have the great influence on the efficient swallowing. The larynx mobility is closely related to the remaining of the hyoid bone. Resection of the hyoid bone or its part is the factor that causes intensified difficulty during swallowing and increase in the frequency of the occurrence of aspiration. The study of effectiveness of glottis or neoglottis performed with the use of laryngograph showed no relation between glottis/neoglottis occlusion effectiveness index and intensified swallowing disorders. This shows the lack of compensating option in swallowing disorders with the help of an mechanism based on an efficient glottis or neoglottis occlusion alone.
