Summary
Autologous fat injection laryngoplasty showed better voice function improvements than framework surgery for unilateral vocal fold paralysis. Fat injection is a more effective therapy for vocal fold paralysis.
Area of Science:
- Otolaryngology
- Speech and Language Pathology
Background:
- Unilateral vocal fold paralysis can significantly impair voice function.
- Surgical interventions aim to restore vocal fold function and improve voice quality.
Purpose of the Study:
- To compare the functional outcomes of framework surgery and autologous fat injection laryngoplasty.
- To determine which procedure offers superior voice function improvement for unilateral vocal fold paralysis.
Main Methods:
- A comparative study involving 62 patients undergoing framework surgery and 64 patients receiving autologous fat injection laryngoplasty.
- Pre- and post-operative voice function assessment using aerodynamic and acoustic analysis.
- Statistical analysis using paired t-tests to evaluate differences within and between groups.
Main Results:
- Both framework surgery and fat injection laryngoplasty led to significant improvements in voice parameters post-operatively.
- Autologous fat injection laryngoplasty demonstrated significantly greater post-operative improvement across all assessed voice parameters compared to framework surgery.
Conclusions:
- Autologous fat injection laryngoplasty is a more effective and reliable treatment for improving voice function in patients with vocal fold paralysis.
- Fat injection laryngoplasty offers superior functional results compared to framework surgery for this patient population.
