Exam 2 Flashcards
What are functional voice disorders the result of?
Incorrect use of some aspect of the phonatory system.
What are two types of functional voice disorders?
Muscle tension dysphonia and psychogenic voice disorders
What are muscle tension dysphonias?
Voice disorders related to misusing the vocal mechanisms
What are the two types of muscle tension dysphonia?
Primary and secondary
What do primary muscle tension dysphonias result from?
Incorrectly using the voice due to some type of hyperfunction/too much muscle tension
What do secondary tissue changes result from?
Develop related to the vocal hyperfunction (vocal nodules or polyps occurring because of vocal abuse)
What are psychogenic voice disorders?
Disorders resulting from emotional trauma or conflict that manifests itself in voice (aka conversion aphonia)
What are organic voice disorders?
Voice disorders due to a physiological abnormality in structure or function at various sites along the vocal tract.
What are neurological voice disorders?
Voice disorders due to problems with muscle control and innervation of the muscles of respiration, phonation, and resonance, which may be impaired from birth or secondary to injury or disease of the peripheral or central nervous system
What are some voice problems with a psychogenic cause?
Functional dysphonia, conversion aphonia, and mutational falsetto
What are the 3 categories of classification by perceptual problems?
Pitch, intensity, and quality
What are pitch changes due to?
Mass changes of the vocal folds
What are some things that might indicate a person is having a pitch problem?
Modal frequency that’s too high or too low, a narrow pitch range, excessive pitch breaks, or a pitch that is inappropriate to the situation
When is intensity considered a problem?
If the voice is too loud or too soft for the demands of a situation.
Vocal quality depends on the condition of what?
The vibratory source
What are quality disorders?
Disturbances in laryngeal tone, usually associated with sound generated at the level of the VF
For a NORMAL VOICE, the condition of the vibratory source depends on what four factors?
- Normal structure
- Normal physiology
- Emotional state does not affect quality
- Good vocal habits
If a voice has a rough, unmusical sound due to excessive laryngeal tension, what quality disorder might we classify that as?
Harsh
If a voice has a rough, unmusical quality with diplophonia or voice breaks, what quality disorder?
Hoarse
What is a resonance quality problem which occurs in the pharynx and results in a tight, hard sound?
Strident
What is a small, childish voice caused by tension in the oral cavity? Usually has a forward tongue carriage.
Thinness
How would we describe a person’s voice is their VF do not have good closure, and a lot of air escapes during phonation?
Breathy
What is a general term that describes any alteration in normal phonation?
Dysphonia
What is it called when a voice has excessive nasality?
Hypernasality
What is it called when the nasal cavities are congested and there is a reduction in nasal resonance?
Hyponasality
What is it called when there is a pharyngeal focus of voice due a posterior tongue carriage and the voice is very “hollow sounding”
Cul-de-sac
A thorough voice evaluation should include what four things?
- Medical examination
- Case history
- Observations of the client
- Testing and evaluation of the client
Who does the medical examination of your voice client?
The ENT!
What four things will the ENT assess the VF for?
- Color
- Position
- Shape
- Movement
What are some of the key components of the case history?
Description of the problem and causal factors, onset and duration of the problem, variability of the problem, and description of vocal use
Why is it important for us to know the onset and duration of the problem?
It might give us an indication of the etiology
When observing the client, what are 3 important things to consider?
Their social history, motivation, and general mental status
What is one of the first informal evaluations we may do to our patients?
Oral peripheral examination, especially looking for any asymmetry, neck tension, or unusual movements of the larynx.
What 4 types of information are we looking for during respiration testing?
- Lung volume
- Air pressure
- Airflow
- Measures of motions of the torso
What do we measure lung volume with?
A dry (or wet) spirometer
What is vital capacity?
The maximum amount of air that can be expelled from the lungs following a maximum inspiration
