Summary
Transcutaneous Teflon augmentation effectively improved voice quality in patients with unilateral vocal cord paralysis. This minimally invasive procedure significantly reduced breathiness, offering a safe and effective vocal cord medialization solution.
Area of Science:
- Otolaryngology
- Speech Pathology
Background:
- Unilateral vocal cord paralysis often results in voice breathiness and reduced quality.
- Vocal cord medialization aims to restore voice function by repositioning the paralyzed cord.
Purpose of the Study:
- To evaluate the efficacy and safety of transcutaneous Teflon augmentation for unilateral vocal cord paralysis.
Main Methods:
- Flexible fiberoptic video-endoscopy guided the procedure.
- Teflon was injected transcutaneously via an 18-gauge needle into the paralyzed vocal cord under local anesthesia.
- Vocal cord position and voice quality were monitored during the procedure.
Main Results:
- All 19 patients experienced reduced voice breathiness, rated as significant improvement.
- The procedure was performed 21 times with no reported complications.
- Two patients required Teflon reinjection for optimal voice results.
Conclusions:
- Transcutaneous Teflon augmentation is a safe and effective method for treating unilateral vocal cord paralysis.
- The procedure leads to significant voice quality improvement by medializing the vocal cord.
