SFS Freevoice

A novel fixation system to facilitate hands-free speech in laryngectomised patients: (SFS-FreeVoice)

As part of our ongoing research, we have successfully analyzed and reconstructed 50 CT scans to better understand the manubrium sterni bone (a part of the chest), which plays a key role in our work. Using this data, we developed a tool to help us identify the most suitable areas for medical implants. Feedback from over 30 patients at a symposium last autumn was essential in improving our initial prototype, which has been well-received by participants. 

Building on this progress, we have now developed and 3D-printed a prototype design, complete with all necessary files and specifications for production. This marks an important step toward creating a usable medical solution. 

The next phase involves finalizing a tested procedure for implanting the prototype. To achieve this, we are conducting detailed micro-CT scans of the manubrium sterni bone in collaboration with the Amsterdam University Medical Center (AMC). Several bone samples have already been scanned and reconstructed, and we are using both new and existing data to develop the final implantation protocol. Once this is completed, we will move forward with our clinical trial, which is currently being prepared. 

Throughout the project, we have shared our findings at various conferences and engaged closely with the patient community. A survey completed by over 50 laryngectomy patients, along with feedback from a symposium attended by around 120 head and neck cancer patients, has been invaluable. Many patients have expressed interest in participating in our clinical trial, further supporting the development of our prototype.

Summary
After removal of the voice box due to cancer, patients often need to occupy one hand to speak, which is a handicap. The current methods facilitate hands-free speech for 20% of patients. The goal of this project is to facilitate this for 80% of all patients by producing a novel fixation method.
