[Evaluation of airway protection against aspiration of gastric contents in patients after partial laryngectomy using the laryngographic closure effectiveness coefficient of the glottis/neoglottis].

Laryngographic examinations were conducted on 97 patients who had undergone partial laryngectomy and on 35 subjects being a control group. 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 a mechanism based on an efficient glottis or neoglottis occlusion alone.
