    Area of Science:

    • Speech-Language Pathology
    • Medical Devices
    • Rehabilitation Medicine

    Background:

    • Laryngectomized patients often face communication challenges post-surgery.
    • Pneumatic artificial larynx devices are used to restore vocal function.
    • The Tokyo (Japanese) artificial larynx is known for its sound production quality.

    Purpose of the Study:

    • To evaluate the effectiveness of the Tokyo artificial larynx in laryngectomized patients.
    • To highlight modifications that overcome the device's limitations.
    • To demonstrate successful patient rehabilitation using this speech aid.

    Main Methods:

    • Review of the Tokyo artificial larynx's design and function.
    • Analysis of modifications addressing usability issues.
    • Presentation of three case reports detailing patient outcomes.

    Main Results:

    • The Tokyo artificial larynx provides high-quality sound production.
    • Developed modifications effectively resolve major usage difficulties.
    • Proper prescription leads to successful speech rehabilitation in case studies.

    Conclusions:

    • The Tokyo artificial larynx is an effective speech aid for laryngectomized individuals.
    • Modifications enhance patient usability and device performance.
    • This device, when appropriately prescribed, significantly aids in vocal rehabilitation.
