Abstract:
Voice is a work tool for many professional groups. Currently, cases of dysphonia of multiple origin consist a growing issue. Voice disorders may result from disturbed voice production process, congenital defects, post-traumatic conditions, chronic diseases or hormonal disorders. Chronic diseases causing voice disorders include laryngopharyngeal reflux disease and esophageal reflux disease.The chronic character of reflux causes the formation of numerous morphological changes of the larynx, including: hyperemia of the mucosa limited to arytenoid and intraarytenoid area, edema of the vocal folds, edema of the larynx mucosa. These changes contribute to voice disorders. Among the pathological changes of voice organ etiologically associated with reflux, the following disease units may be distinguished: reflux laryngitis, subglottic edema, contact ulceration, larynx granuloma, larynx and pharynx cancer. Many of disorders in the upper respiratory tract are etiologically related to reflux, e.g. dysphonia, grunting, coughing and dyspnoea.
