Surgical voice restoration for vocal cord paralysis offers options like Teflon injection, thyroplasty, and reinnervation. While Teflon is fast and cheap, nerve transfer provides the best voice quality and preserves vocal cord integrity.

Area of Science:

  • Otolaryngology
  • Laryngeal Surgery
  • Voice Restoration

Background:

  • Surgical rehabilitation of vocal cord paralysis is crucial for restoring voice function.
  • Current techniques include Teflon injection, thyroplasty, and reinnervation.
  • Debate exists regarding the optimal technique for achieving superior phonatory quality.

Purpose of the Study:

  • To compare the efficacy of Teflon injection, thyroplasty, and reinnervation for vocal cord paralysis.
  • To evaluate phonatory outcomes and vocal cord preservation.
  • To determine the most effective surgical approach for voice restoration.

Main Methods:

  • Review of existing literature and clinical experience with Teflon injection, thyroplasty, and reinnervation.
  • Analysis of voice quality using stroboscopic and other voice analyses.

  • Assessment of vocal cord status and preservation.

    • Main Results:

    • Teflon injection is the quickest and least expensive procedure.
    • Thyroplasty and reinnervation demonstrate some superiority in phonatory quality over Teflon injection.
    • Nerve transfer (reinnervation) offers the best opportunity for achieving a normal phonatory voice and preserves vocal cord integrity.

    Conclusions:

    • While Teflon injection is a rapid and cost-effective option, newer techniques offer improved phonatory outcomes.
    • Nerve transfer presents the most promising approach for achieving natural voice quality and maintaining vocal cord health.
    • The nerve transfer technique is advantageous as it leaves the vocal cord undisturbed, allowing for future interventions if necessary.
