[Comparative intensity-pressure study of patients with a voice prosthesis].

We have studied the qualities of the voice of the laryngectomized patients and theirs possibilities to modify the intensity depending to the pressure. During the measurement, it was necessary to explain to the patient how to use the material and it was an opportunity to help him in the way to product a voice prosthesis. Most of the patients produced a higher intensity with a higher pressure. However, some of them obtained high pressures without producing a voice. These patients modified the use of the prosthesis or could have an oedema for example. In conclusion, these measurements show that there is a relation between intensity and pressure but not absolutely in relation with a better voice quality.
