[The impact of vibratory stimulation therapy on voice quality in hyperfunctional occupational dysphonia].
UNLABELLED Hyperfunctional dysphonia is the most frequent type of occupational functional dysphonia. Pharmacotherapy, physiotherapy and psychotherapy are used in the treatment of occupational dysphonia. Vibratory massages of the regions of the larynx relax the external muscles of neck, which have an indirect impact on the tension of the vocal folds. PURPOSE The aim of the study is to assess t...
متن کاملVideostroboscopic and morphological aspects of voice disturbances in patients with larynx atrophy and coexisting hypopharynx cancer.
Vocal folds play a crucial role in voice production. The physiological vibrations of vocal folds depend on the unchanged multilayered structure of the vocal folds mucosa. Morphological changes of mucosa are the cause of voice quality disorders - dysphonia. The aim of this study was to determine the morphological base of dysphonia in patients with vocal folds atrophy. A group of 24 patients with...
متن کاملEpithelial Cell Detection in Endomicroscopy Images of the Vocal Folds
The reasons for a hoarse voice are manifold. Besides structural changes such as additional masses on the vocal folds, changes in the layers of the vocal fold mucus influence the acoustic properties of the voice signal [3]. In our research, we aim to examine this in vivo. One suitable technique for this purpose is the use of micro endoscopes. In contrast to traditional microscopes, the micro end...
متن کاملDynamic digital image correlation of a dynamic physical model of the vocal folds
An experimental study of the vibratory deformation of the human vocal folds was conducted. Experiments were performed using model vocal folds made of soft silicone rubber, and an air supply system. The model self-oscillated at fundamental frequencies and flow rates typical of the human folds. Time-averaged mass flow rates and transglottal pressures were measured along with the sound pressure up...
متن کاملEffects of RLN and SLN stimulation on glottal area.
In vivo canine experiments have demonstrated that vocal fold stiffness varies proportionately with changing levels of recurrent laryngeal nerve (RLN) and superior laryngeal nerve (SLN) stimulation. This study evaluated the morphologic changes in the glottis at varying levels of nerve stimulation and the presumed effects on laryngeal air particle velocity. Stroboscopic data from the in vivo cani...
