For example, Muscle Tension Dysphonia (MTD) has been found to be a result of many different causes including the following: MTD in the presence of an organic pathology (i.e. organic type), MTD stemming from vocal use (i.e. functional type), and MTD as a result of personality and/or psychological factors (i.e. psychogenic type). (wikipedia.org)
[ 4 ] As a result, the term muscle tension dysphonia (MTD) has become the preferred term for functional dysphonia. (medscape.com)
A hoarse voice, also known as dysphonia or hoarseness, is when the voice involuntarily sounds breathy, raspy, or strained, or is softer in volume or lower in pitch. (wikipedia.org)
Studies suggest that dysphonia is a partial loss of the voice that manifests itself in a weak, hoarse, raspy or breathy voice. (muysalud.com)
Laryngeal3
The distinction between these broad classes stems from their cause, whereby organic dysphonia results from some sort of physiological change in one of the subsystems of speech (for voice, usually respiration, laryngeal anatomy, and/or other parts of the vocal tract are affected). (wikipedia.org)
Factors that influence either the aerodynamic configuration (ie, vocal fold paralysis) or the vibratory property of the glottis (ie, laryngeal cyst) may result in dysphonia. (medscape.com)
Notice how the breathy, strained quality sounds similar to nodules or some other lesion of the vocal folds, reminding us that it is imperative to have a laryngeal examination before trying to treat, or work with, a voice that is obviously disorderd. (vocapedia.info)
Psychogenic1
Notably, an additional subcategory of functional dysphonia recognized by professionals is psychogenic dysphonia, which can be defined as a type of voice disorder that has no known cause and can be presumed to be a product of some sort of psychological stressors in one's environment. (wikipedia.org)
Lesion3
in contrast, structural dysphonia is defined as impaired functioning of the vocal mechanism that is caused by some sort of physical change (e.g. a lesion on the vocal folds). (wikipedia.org)
An Italian study found that approximately 90% of children with dysphonia from a vocal fold lesion had an underlying functional dysphonia. (medscape.com)
Notice how the breathy, strained quality sounds similar to nodules or some other lesion of the vocal folds, especially with the loss of higher pitches. (vocapedia.info)
Phonation1
The term dysphonia describes a qualitative or quantitative phonation disorder characterized by a difficulty in producing sounds when speaking. (muysalud.com)
Multidisciplinary2
The assessment and diagnosis of dysphonia is done by a multidisciplinary team, and involves the use of a variety of subjective and objective measures, which look at both the quality of the voice as well as the physical state of the larynx. (wikipedia.org)
While the causes of dysphonia can be divided into five basic categories, all of them result in an interruption of the ability of the vocal folds to vibrate normally during exhalation, which affects the voice. (wikipedia.org)
However, when vocal quality deteriorates in the absence of anatomic and neurologic factors, a functional voice disorder should be suspected. (medscape.com)
Aphonia and dysphonia are the result of changes in the structure or functioning of the vocal cords , with some differences in the severity of presentation. (muysalud.com)
Organic4
Dysphonia can be categorized into two broad main types: organic and functional, and classification is based on the underlying pathology. (wikipedia.org)
citation needed] Multiple treatments have been developed to address organic and functional causes of dysphonia. (wikipedia.org)
Functional dysphonias may be treated through direct and indirect voice therapies, whereas surgeries are recommended for chronic, organic dysphonias. (wikipedia.org)
Voice disorders can be divided into 2 broad categories: organic and functional. (wikipedia.org)

Voice disorders such as aphonia and dysphonia are very similar to each other, so they tend to be confused very often. (muysalud.com)
In most cases, aphonia and dysphonia are benign disorders associated with inadequate coordination of the elements that participate in the production of the voice. (muysalud.com)
Pitch1
After an intensive 2-month voice therapy program, habitual pitch was reduced to 220 Hz and voice was functional. (medscape.com)
Sounds1
It describes the total inability to emit words or sounds , which can evolve from dysphonia or appear suddenly. (muysalud.com)
