Devices and methods for anterior arytenoid adduction

摘要

Provided herein are devices and methods for anterior arytenoid adduction. The device may comprise a wire having a first end and a second end at opposite ends of a longitudinal axis, the wire forming a spiral along the longitudinal axis and having a double hook at the first end, a suture threaded through the spiral of the wire from the second end to the first end, the suture forming a turn at the first end and passing exterior to the spiral to the second end. The method may comprise advancing a suture and hook from the subject's anterior thyroid cartilage or cricothyroid membrane to the muscular process of the subject's arytenoid, attaching the hook to the muscular process, and applying tension to the suture to rotate the muscular process and adduct the arytenoid.

主权项

1. A method for anterior arytenoid adduction in a subject in need thereof, the subject having a larynx having an arytenoid with a muscular process, vocal folds, and a glottal gap between the vocal folds, the method comprising:
advancing a suture wire complex from the subject's anterior thyroid cartilage to the muscular process of the subject's arytenoid, the suture wire complex comprising a wire hook complex connected to a suture, attaching a hook from the wire hook complex to the muscular process; and applying tension to the suture to rotate the muscular process and adduct the arytenoid.
