  Purpose

The benefits of this new material, as demonstrated in animal studies and preliminary studies in man, could provide the answer to problems encountered by surgeons in the field of phonatory implants. This novel application is a step towards resolving the very real problems which still exist in the field today. The functional concept, which will allow better control over integrating implants in tissue, should also, it is hoped, favour cellular colonization, thereby fulfilling a currently unmet medical need. The aim is to avoid well-identified potential complications linked to the use of silicone-only implants (with or without a surface coating), like leakage around the prosthesis (by cellular colonization), and so reduce the risk of protrusion/extrusion of the prosthesis as far as possible, and to avoid trauma to the peri-prosthetic tissues by repeated interventions

Secondary Outcome Measures:
  • Phonology's measures [ Time Frame: months 1, 3,12 ] [ Designated as safety issue: No ]

Estimated Enrollment: 14
Study Start Date: December 2007
Estimated Study Completion Date: March 2014
Estimated Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: prothesis voice
    The device may be used for patient using another type of voice prosthesis, of for patient undergoing total laryngectomy. This device is definitively placed in two parts:The first one is introduced in the puncture (TEP) through the esophagus (retrograde way). The second part is then clipped on the first one through the tracheotomy orifice (anterograde way).A third part containing the valve can then be clipped in the prosthesis and easily removed in order to change it as often as necessary.
    Procedure: total laryngectomy
    The second part is then clipped on the first one through the tracheotomy orifice (anterograde way).A third part containing the valve can then be clipped in the prosthesis and easily removed in order to change it as often as necessary.
