Objectives: We report development of a device and technique to manage laryngeal paralysis through minimal-access arytenoid adduction (for unilateral paralysis) and arytenoid abduction (for bilateral paralysis).
Methods: A human cadaver study coupled with directed engineering was used to develop instrumentation designed to secure the muscular process of the arytenoid into favorable adducted or abducted positions. Digital video, photography, and 3-dimensional computed tomographic (CT) imaging of cadaveric larynges were done to evaluate the surgical technique.
