Overall Status
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
