Summary
Hyaluronic acid injection laryngoplasty for vocal fold paralysis may promote neural plasticity. This early intervention shows potential for improving motor pathway integrity and supporting vocal fold recovery.
Area of Science:
- Neuroscience
- Otolaryngology
- Speech and Language Pathology
Background:
- Unilateral vocal fold paralysis (UVFP) impacts vocal fold mobility and phonation.
- Previous research suggests brainstem activation during phonation tasks before vocal fold recovery.
- The potential for peripheral interventions to influence neural plasticity in UVFP is an area of active investigation.
