Effect of Vocal Fold Medialization on Dysphagia in Patients with Unilateral Vocal Fold Immobility.
OBJECTIVE The effect of vocal fold medialization (VFM) on vocal improvement in persons with unilateral vocal fold immobility (UVFI) is well established. The effect of VFM on the symptom of dysphagia is uncertain. The purpose of this study is to evaluate dysphagia symptoms in patients with UVFI pre- and post-VFM.

متن کاملA fluid-structure interaction model of vocal fold oscillation
Since fluid-structure interaction within the finite-element method is state of the art in many engineering fields, this method is used in voice analysis. A quasi two-dimensional model of the vocal folds including the ventricular folds is presented. First results of self-sustained vocal fold oscillation are presented and possibilities as well as limitations are discussed.
متن کاملMarathon despite unilateral vocal fold paralysis.
The principal symptoms of unilateral vocal fold paralysis are hoarseness and difficulty in swallowing. Dyspnea is comparatively rare (Laccourreye et al., 2003). The extent to which unilateral vocal fold paralysis may lead to respiratory problems at all – in contrast to bilateral vocal fold paralysishas not yet well been determined. On the one hand, inspiration is impaired with unilateral vocal ...
متن کاملVocal improvement after voice therapy in unilateral vocal fold paralysis.
Unilateral vocal fold paralysis (UVFP) is associated with changes in acoustic and aerodynamic voice measurements and can have a significant impact on a patient's quality of life. Few objective data regarding the efficacy of voice therapy for UVFP exist. The aim of this study was to retrospectively analyze voice modifications in a group of patients with UVFP before and after voice therapy. Forty...
