Microendoscopy of Reinke

Area of Science:

  • Laryngology and Voice Restoration
  • Minimally Invasive Surgical Techniques
  • Biomaterials in Voice Surgery

Background:

  • Vocal fold scarring impacts voice quality.
  • Current treatments for vocal fold scarring have limitations.
  • Novel minimally invasive approaches are needed for vocal fold repair.

Purpose of the Study:

  • To evaluate Microendoscopy of Reinke's space (MERS)-guided minithyrotomy for vocal fold scarring.
  • To assess the histologic and rheologic outcomes of MERS-guided procedures.
  • To evaluate the instrumentation used in MERS-guided surgery.

Main Methods:

  • Preclinical study using human cadaveric and porcine larynges.
  • MERS-guided injection of biomaterials (Radiesse VoiceGel, HyStem-VF).

  • Histologic evaluation of biomaterial placement and rheologic assessment of vocal fold properties.

    • Main Results:

    • MERS provided real-time visualization and accurate biomaterial positioning.
    • Histology confirmed desirable subepithelial placement of biomaterials.
    • Rheologic analysis showed no significant difference in vocal fold viscoelasticity post-treatment.

    Conclusions:

    • MERS-guided laryngoplasty demonstrates potential for treating vocal fold scarring.
    • The technique allows for precise biomaterial delivery while preserving epithelium.
    • Further research is warranted to explore MERS for intracordal pathologies.
