    Summary
    This summary is machine-generated.

    Voice misuse causes vocal cord changes. Treatments like voice therapy, surgery, and injections can restore voice function, though reinnervation procedures are still developing.

    Area of Science:

    • Otolaryngology
    • Speech-Language Pathology

    Background:

    • Vocal cord misuse (loudness, duration, low pitch) causes chronic lamina propria changes.
    • Irritant inhalation affects the true vocal cord epithelium.
    • Voice therapy is crucial for surgical patient management.

    Purpose of the Study:

    • To review the pathological changes in vocal cords due to misuse and irritants.
    • To discuss various surgical and therapeutic interventions for voice restoration.

    Main Methods:

    • Review of pathological changes associated with vocal abuse and irritant exposure.
    • Discussion of surgical techniques including operative microscopy and nerve resection.
    • Evaluation of therapeutic interventions such as voice therapy and Teflon injection.

    Main Results:

    • Chronic lamina propria changes result from vocal misuse; epithelial changes from irritants.
    • Operative microscopy aids in preserving the external elastic lamina for voice range restoration.
    • Recurrent laryngeal nerve resection benefits spastic dysphonia; Teflon injection effective for unilateral paralysis.

    Conclusions:

    • Surgical and therapeutic interventions offer significant voice restoration.
    • Preservation of vocal cord structures and targeted treatments are key.
    • Reinnervation procedures for laryngeal nerve paralysis are currently experimental.
