Integrated study of respiration and deglutition includes 48 healthy examinees and 22 patients after laryngectomy. Laryngectomy changes the relationship between breathing and swallowing. In healthy subjects 70.68 per cent of swallows occurs during the expiratory phase and more than 80 per cent are followed by expiration. In the patients after laryngectomy 58.01 per cent of swallows coincide with the end of the expiration end the beginning of the inspiration and near 80 per cent of swallows are followed by inspiration. Laryngectomy eliminates necessity for specific coordination of breathing and swallowing and makes possible manifestation of the central neural control.
