A novel surgical technique implants a Hydron rod to correct glottic insufficiency, significantly improving voice quality and reducing vocal fatigue in patients. This minimally invasive procedure offers effective voice restoration.

Area of Science:

  • Otolaryngology
  • Speech Pathology
  • Biomaterials Science

Background:

  • Vocal fold insufficiency can lead to significant voice impairment and reduced quality of life.
  • Current treatment options for glottic insufficiency may have limitations or undesirable side effects.
  • A minimally invasive surgical approach is needed to effectively address vocal fold closure issues.

Purpose of the Study:

  • To describe a new surgical operation for correcting insufficient glottic closure.
  • To evaluate the efficacy of Hydron rod implantation for voice improvement.

Main Methods:

  • A submucosal tunnel was created in the vocal mucosa using specialized instruments.
  • A spindle-form Hydron gel rod was implanted via direct laryngoscopy under general anesthesia.

  • The operative microscope was utilized for enhanced visualization and illumination during the procedure.

    • Main Results:

    • The operation was successfully performed on 40 patients.
    • Sound analysis demonstrated a significant improvement in voice quality.
    • Patients reported a considerable subjective decrease in symptoms, particularly voice fatiguability.

    Conclusions:

    • Hydron rod implantation is an effective surgical treatment for glottic insufficiency.
    • The procedure leads to measurable improvements in voice quality and patient-reported outcomes.
    • This technique offers a promising solution for patients suffering from vocal fold closure deficits.
