Document Summary
Overuse of one"s voice can cause permanent tissue change. Voice disorder: quality of communication function1 is impacted by unreliable, attention-getting absent vocalization due to (loudness, pitch, qualify). Alterations: too little/too much tension; too little/too much. Loudness: result primarily of expiratory force but also varies with muscle tension of vocal fold. Quality: vocal traits are as distinctive as our faces and as difficult to describe. unremarkable when both vocal cords are working well together. The dynamic of speech requires that we open/close the velopharyngeal port many times in a short period of time. Hyperfunctional: spasticity, chronic shouting - too much movement. Alaryngeal: speech in the absence of the larynx. Descriptive: with or without reference to etiology o. Focuses on dominant characteristics of vocal behaviors that is/are problematic. Never ever treat voice disorder until patient has been seen. Etiology: neurogenic vs functional vs psychogenic o o o. Functional: structural deviation or change in phonatory mechanism due to misuse or abuse of voice.
