    Summary

    This study presents a novel glottic reconstruction technique after vertical partial laryngectomy to improve voice function. The method utilizes a sternohyoid muscle flap to create an adequate bulge for better glottic closure.

    Area of Science:

    • Otolaryngology
    • Surgical Techniques
    • Voice Restoration

    Background:

    • Vertical partial laryngectomy can impair phonatory function due to inadequate glottic closure.
    • Reconstruction aims to restore vocal fold function by achieving adequate closure, proper bulge height, and a smooth surface.

    Purpose of the Study:

    • To describe a new glottic reconstruction technique following vertical partial laryngectomy.
    • To achieve optimal phonatory function by meeting key reconstructive requirements.

    Main Methods:

    • A sternohyoid muscle flap is created from the upper portion, dissected 5 cm below the vocal fold.
    • The flap is rotated 90 degrees and inserted into the laryngeal wound to form a bulge.
    • The muscle flap is covered with hypopharyngeal or lip mucosa.

    Main Results:

    • The described technique facilitates the creation of a bulge at the vocal fold level.
    • This method aims to ensure adequate glottic closure during phonation.
    • The technique promotes a smooth surface for the reconstructed bulge.

    Conclusions:

    • The described sternohyoid muscle flap technique offers a viable method for glottic reconstruction.
    • This approach addresses critical factors for successful voice restoration after vertical partial laryngectomy.
    • The technique aims to improve phonatory outcomes by optimizing glottic function.
