    Researchers developed an implantable electronic laryngeal prosthesis system. Early results show successful device fabrication and implantation, with potential for vocal rehabilitation after laryngectomy.

    Area of Science:

    • Biomedical Engineering
    • Otolaryngology
    • Prosthetics

    Background:

    • Total laryngectomy necessitates alternative methods for vocal rehabilitation.
    • Development of implantable electronic devices offers a promising avenue for restoring voice.
    • Previous research has explored various prosthetic solutions for post-laryngectomy speech.

    Purpose of the Study:

    • To report preliminary findings on the development of an implantable electronic laryngeal prosthesis system.
    • To evaluate the feasibility and initial outcomes of the retropharyngeal transducer and induction coil system.
    • To assess complications and acoustical performance of the device in preclinical studies.

    Main Methods:

    • Design and fabrication of an implantable, retropharyngeal transducer and secondary induction coil.
