    Area of Science:

    • Biomedical Engineering
    • Otolaryngology
    • Speech Therapy

    Background:

    • Laryngectomized cancer patients often require speech rehabilitation.
    • Esophageal speech is a common but not universally suitable method.

    Purpose of the Study:

    • To develop an alternative speech rehabilitation method for laryngectomized patients.
    • To create an implantable electromagnetic sound source for voice production.

    Main Methods:

    • Collaborative effort between otolaryngologists, biomedical engineers, and speech therapists.
    • Development of a biocompatible and durable implantable device.
    • Testing in animal models to assess functionality.

    Main Results:

    • Successful production of an implantable electromagnetic sound source.
    • Demonstrated biocompatibility and durability in animal experiments.
    • Device is functional for voice production.

    Conclusions:

    • The developed device shows promise as a viable alternative for speech rehabilitation.
    • The technology is ready for a small, carefully selected clinical trial.
