Predicting the outcome of unilateral vocal fold paralysis: A multivariate discriminating model including grade of dysphonia, jitter, shimmer, and Voice Handicap Index-10
Annals of Otology, Rhinology & Laryngology Apr 19, 2019
Lovato A, et al. - Using laryngostroboscopy, the GIRBAS (grade, instability, roughness, breathiness, asthenia, and strain) scale, acoustic analysis, and the Voice Handicap Index-10 (VHI-10) questionnaire, 46 individuals were analyzed to estimate whether any clinical and phoniatric characteristics or quality-of-life measures could predict the outcome of unilateral vocal fold paralysis (UVFP) initially managed with speech therapy. An association of time to diagnosis (0.01), the global grade of dysphonia (0.018), jitter (0.01), shimmer (0.012), and VHI-10 score (0.006) was noted with the outcome of vocal fold paralysis. They also found a relationship between delayed diagnosis as well as speech therapy and negative outcomes. Higher grade of dysphonia, jitter, shimmer, and VHI-10 score on initial phoniatric assessment seemed to support the clinicians in predicting the consequences of UVFP cases.
