title: Investigation of intra-esophageal air kinetics and esophageal sphincters in patients with total laryngectomy during esophageal speech.
abstract: The purpose of this study was to evaluate the air kinetics of well- and poor-speaking patients and their upper (UES) and lower (LES) esophageal sphincter pressures . The esophageal speech capability of 23 total laryngectomy patients was assessed with the Wepman scale. LES and UES points and pressures were measured, and air kinetics were compared. All patients were male, with an average age of 58 years. Both the LES and UES pressures were not statistically different between good-speaking and poor-speaking patients (p > 0.05). The ability to speak was estimated only by looking at tracings. Good speakers are able to retain air successfully and on a long-term basis between the upper and lower esophageal sphincters. During short and/or rapid speech, these patients are able to rapidly suck and then expel the air from their upper esophagus. During long speeches, after sucking the air into their distal esophagus, they used the air in the upper part of the esophagus during the speech, only later seeming to fill the lower esophagus with the air as a possible reserve in the stomach. It has been shown that the basic requirement for speaking is the capacity to suck and store the air within the esophagus. For successful speech, the air should be stored inside the esophagus. MII technology contributes to our understanding of speech kinetics and occupies an important place in patient training as a biofeedback technique.
