Thyroplasty type I can sometimes fail, requiring revision surgery. Modifications to the surgical technique, including cartilage cutting and silicone plug use, aim to improve vocal cord medialization and voice outcomes.

Area of Science:

  • Otolaryngology
  • Speech and Voice Science

Background:

  • Thyroplasty type I is a common surgical procedure for vocal cord medialization.
  • Post-operative voice reversion can occur, necessitating revision surgery.

Purpose of the Study:

  • To describe modifications to the thyroplasty type I technique to improve vocal cord medialization.
  • To define criteria for overmedialization during surgery.

Main Methods:

  • Modified thyroplasty type I technique involving precise cartilage cutting.
  • Use of a silicone plug for enhanced vocal cord fixation and medialization.
  • Development of intraoperative criteria for assessing vocal cord overmedialization.

Main Results:

  • Revision surgery in five cases led to voice improvement.

  • The modified technique aims to prevent voice reversion and enhance medialization outcomes.

    • Conclusions:

    • Modifications to thyroplasty type I can improve surgical outcomes.
    • Precise cartilage management and silicone plug fixation are key to successful vocal cord medialization.
