The objective of this study is to show the feasibility of detecting the specific activity of 2 muscles during swallowing using invasive sensors in healthy volunteers.
Total laryngectomy, which involves removing the larynx and performing a tracheostomy, is the standard method of surgical treatment for advanced laryngeal cancer.
It changes the patient's life and has an significant impact on his overall quality of life.
Over the last 10 years, numerous trials of artificial larynx implantation have been tested, but currently there is no method of implanting a system that detects the onset of a swallow.
The DEGLUTITION study aims to show the feasibility of detecting the specific activity of 2 muscles in swallowing using intramuscular electromyograms in healthy volunteers.

Measure of TS time variable in milliseconds corresponding to passage of the food bolus through the upper esophageal sphincter. TS is assessed by signals acquired from the microphone.
| 2 hours |
| Measurement of the TD time variable | Measure of TD time variable in milliseconds corresponding to start of swallowing by activation of the submandibular area.TD is assessed by signals acquired from the microphone. | 2 hours |
Measure of integral of signals for each type of swallowing tasks (of different types of food bowls) and non-swallowing tasks (turning the head, opening the mouth, talking, smiling) |
| 2 hours |
| Measurement of Root Mean Square of signals for each type of swallowing and non-swallowing tasks | Measure of Root Mean Square of signals for each type of swallowing tasks (of different types of food bowls) and non-swallowing tasks (turning the head, opening the mouth, talking, smiling) | 2 hours |
