Summary
Vocal cord medialization using Bioplastique (Vox-implant) injection is a safe and effective treatment for unilateral laryngeal paralysis. This minimally invasive procedure significantly improves voice quality and swallowing function, with high patient satisfaction.
Area of Science:
- Otolaryngology
- Speech and Hearing Science
Background:
- Unilateral laryngeal paralysis can lead to significant voice and swallowing impairments.
- Vocal fold medialization aims to restore glottic closure and improve vocal function.
Purpose of the Study:
- To evaluate the preliminary outcomes of endoscopic vocal fold medialization using Bioplastique (Vox-implant).
Main Methods:
- Retrospective study of 39 patients with unilateral laryngeal paralysis treated with Vox-implant injections.
- Swallowing function assessed by video fluoroscopy.
- Vocal function evaluated using the Voice Handicap Index 10 (VHI-10) questionnaire.
Main Results:
- 18 out of 19 patients with swallowing disorders showed normal video fluoroscopy post-treatment.
- Significant improvement in Voice Handicap Index 10 scores (p<0.001), indicating a 53% average reduction in voice handicap.
- 32 patients reported satisfaction with post-operative vocal results.
Conclusions:
- Endoscopic vocal fold medialization with Bioplastique (Vox-implant) is a simple, well-tolerated procedure.
- It effectively improves voice quality and resolves swallowing issues.
- The procedure is repeatable, with thyroplasty as a viable alternative in cases of failure.
