Abstract

Objectives Research evidence has shown that neither traditional voice therapy nor surgery was efficacious in managing age-related dysphonia, specifically for more severe cases with pronounced fold atrophy or larger glottal gaps. The purpose of this study was to examine the efficacy of intensive respiratory-phonatory treatment (Lee Silverman voice treatment [LSVT]) for glottal incompetence associated with presbyphonia. Study Design Nonrandomized prospective study. Methods Two subjects with age-related vocal fold bowing received 4 weeks of the LSVT. Strobolaryngoscopic examination, phonatory function measurement, acoustical analyses, and perceptual judgments of voice were obtained at baseline and 2 weeks posttreatment. Additional acoustic measures of phonatory function, including vocal intensity, maximum phonation time, and pitch range, were also obtained during 16 treatment sessions. Results Both subjects exhibited significant improvements in glottal closure, phonatory function, acoustic features, and perceptual ratings of voice after treatment. Significant changes of phonatory function measures were noticed relatively early and remained steady throughout the course of treatment. Conclusions These findings provide solid evidence that speakers with age-related vocal fold bowing and dysphonia may improve glottal competence and related vocal function with neither laryngeal trauma nor maladaptive laryngeal hyperfunction after the LSVT.
