Thyroplasty type I for unilateral vocal cord paralysis

Area of Science:

• Otolaryngology
• Laryngology
• Surgical Innovation

Background:

• Unilateral vocal cord paralysis stems from various causes including trauma, neoplasms, neurological issues, and post-surgical complications.
• This condition significantly impacts voice quality and can affect airway patency.
• Existing treatments aim to restore vocal fold function and closure.

Purpose of the Study:

• To describe Thyroplasty type I, a laryngeal framework surgery for unilateral vocal cord paralysis.
• To detail the surgical technique involving silicone implant placement.
• To highlight the intraoperative phonation and potential complications.

Main Methods:

• Thyroplasty type I involves creating a window in the thyroid cartilage.
• A silicone implant is precisely positioned to medialize the paralyzed vocal cord.
• The procedure is conducted under monitored local anesthesia with conscious sedation, allowing patient phonation.

Main Results:

• The technique successfully medializes the paralyzed vocal cord.
• Intraoperative phonation confirms the implant's effect on vocal cord approximation.
• The primary complication identified is potential airway compromise.

Conclusions:

• Thyroplasty type I is an effective phonosurgical option for unilateral vocal cord paralysis.
• The procedure facilitates vocal cord closure by repositioning the paralyzed cord.
• Careful monitoring for airway compromise is essential during and after the surgery.
