Correlating voice handicap index and quantitative videostroboscopy following injection laryngoplasty for unilateral vocal paralysis

Voice handicap index correlates best with glottic closed phase, suggesting duration of vocal fold closure during the glottic cycle best represents patients’ subjective outcome post-procedure. Progressive improvement in voice handicap index beyond six months may relate to gradual reduction in compensatory supraglottic compression, with moderate correlation.
