Oesophageal speech were described for the first time by Gutzmann in 1909. The diagnostic method based upon checking the pressure causing opening of oesophagus mouth was developed by Seeman and Van Den Bergh. In the initial stage, the method was meant to determine the level, to which the patient can master oesophageal speech. In the course of further investigations, an additional element of diagnostics was noted, which enabled early detection of recurrence of the neoplastic process in the oesopagus mouth area.


The material includes 96 patients treated in 2008-2010 at the Department of Otolaryngology, Medical University in Katowice. All patients were classified on the basis of CT of the larynx and the result of histopathological examination to the total laryngectomy. All the patients were subjected to examination by device to visualize the process of opening pressure of the sphincter of the esophagus paragraph.


During two years of observation in 28 cases (29%), oesophageal pressure was open his mouth more than 80 mmHg. When performed CT of the neck and histopathology examination recurrence of laryngeal cancer was confirmed in 23 cases (82%).


This device is used to determine the best method of voice and speech rehabilitation in patients after total laryngectomy and early diagnosis of laryngeal and/or hypopharynx cancer recurrence.
