Cost-effectiveness Analysis of Vocal Rehabilitation With Strengthened Tracheoesophageal Voice Implant Prosthesis Versus Standard Voice Prosthesis in Case of Repeated Intra-prosthetic Leakage After Total Laryngectomy

2019-09-27 06:30:40 | BioPortfolio


The purpose of this study is to determine the cost-effectiveness of vocal rehabilitation with reinforced inter-tracheoesophageal voice prosthesis versus standard voice prosthesis in case of repeated intra-prosthetic leakage in total laryngectomy patients.

This is a one year medico-economic study involving patients carrying a standard voice prosthesis implant and having undergone 2 successive prosthesis replacements within 3 months of interval and/or requiring at least 4 changes in the last 12 months, for intraprosthetic leakage.

Eligible subjects will be randomized in 2 groups: reinforced prosthesis with silver coating and double valve (Dual Valve) or standard prosthesis (single unreinforced valve), of the same model as the prosthesis previously implanted in the patient.


Prosthetic voice rehabilitation is a widespread practice that allows the patient to resume phonation quickly after total laryngectomy/total pharyngolaryngectomy/total circular pharyngolaryngectomy.

When the longevity of the implant is abnormally short (less than 3 months), the multiplication of changes is likely to increase the risk of overall morbidity related to maintaining the functionality of the voice prosthesis and to alter the patient's quality of life.

Reinforced innovative prostheses, currently not supported by the French Social Security, delay the occurrence of intraprosthetic leakage compared to standard prostheses.

This study assesses the economic efficiency from a societal perspective and a one-year time horizon, from vocal rehabilitation with reinforced inter-tracheoesophageal prosthesis versus standard voice prosthesis in case of intra-tracheal leakage in total laryngectomy patients.

Patients are randomized in 2 arms. Arm A usual care with reinforced prosthesis, or arm B usual care with standard prosthesis. Each patient is followed during 12 months.

Medical and Biotech [MESH] Definitions

A prosthetic appliance for the replacement of areas of the maxilla, mandible, and face, missing as a result of deformity, disease, injury, or surgery. When the prosthesis replaces portions of the mandible only, it is referred to as MANDIBULAR PROSTHESIS.

The plan and delineation of prostheses in general or a specific prosthesis.

Surgical insertion of a prosthesis.

Holding a PROSTHESIS in place.

The selected form given to a natural tooth when it is reduced by instrumentation to receive a prosthesis (e.g., artificial crown or a retainer for a fixed or removable prosthesis). The selection of the form is guided by clinical circumstances and physical properties of the materials that make up the prosthesis. (Boucher's Clinical Dental Terminology, 4th ed, p239)
