Classification of Voice Disorders Flashcards
What are the 3 physical classifications of voice disorders?
Functional, Organic, Neurogenic
What is a functional voice disorder?
A result of incorrect use of some aspect of the phonatory system
What are the two types of functional voice disorders?
- Muscle tension dysphonia
2. Pyschogenic voice disorder
What is muscle tension dysphonia?
Voice disorders related to the misuse of the vocal mechanisms, producing a hypertension type of dysphonia
Muscle tension dysphonia includes what two types?
Primary
Secondary
What is a primary muscle tension dysphonia?
Incorrectly using the voice (hyperfunction)
What is a secondary muscle tension dysphonia?
Occurs secondary to hypertension- Can often be classified as vocal nodules or polyps on the VF
What is a psychogenic voice disorder?
Results from emotional trauma or conflict that manifests itself in voice
What is a psychogenic voice disorder also known as?
conversion aphonia
Characteristics of a psychogenic voice disorder
- aphonia (lack of voice)
- generally normal VF
- not faking it
- often occurs secondary to an upper respiratory infection or laryngitis and persists past the illness
What is an organic voice disorder?
Due to a physiological abnormality in structure and/or function at various sites along the vocal tract
What is a neurogenic voice disorder?
Neurological voice disorders are 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 to the PNS or CNS
What is diplophonia?
- Caused by muscle tension
- production of a voice at two pitches
- Using the true folds and the false folds at the same time
What is Reinke’s edema?
- Caused by muscle tension
- accumulation of fluid under the VF cover in Reinke’s space- VF become rather thick and floppy
What is Traumatic Laryngitis?
- caused by excessive yelling
- Trauma to the VF
- results in hoarseness but often resolves in a few days
What is a phonation break?
voice cuts out during phonation
List at least 5 disorders that have a muscle tension problem as the cause
Ventricular Dysphonia Muscle Tension Dsyphonia Vocal Fold Thickening Diplophonia Reinke's edema Traumatic Laryngitis Vocal polyps Pitch and phonation breaks
3 types of voice problems that have a psychogenic cause?
- Functional dysphonia
- Conversion aphonia
- Mutational falsetto
What is functional dysphonia?
- A voice that sounds abnormal with a completely normal larynx
- adopted a dsyphonia
- can be remediated in a matter of one or two voice therapy
What is conversion aphonia?
- A type of psychogenic voice disorder
- Complete loss of voice (whisper voice)
What is mutational falsetto?
- A type of psychogenic voice disorder
- Normal larynx
- Individual holds onto their prepubescent voice
- typically occurs in males
Name 10 voice disorders with an organic cause
- sulcus vocalis
- cancer
- leukoplakia
4, hemangioma - hyperkeratosis
- laryngectomy
- Granuloma
- Webbing
- Infectious laryngitis
- hypothyroidism
What is sulcus vocalis?
- A congenital or acquired disorder
- unknown etiology
- Results in a long, oval shaped glottal opening during adduction or by a line running longitudinally parallel to the glottis down one or both vocal cords
When is a contact ulcer due to an organic cause?
In cases of GERD
What is leukoplakia?
- white patches
- due to some type of environmental irritation
- smoking or excessive alcohol use
- pre-cancerous
How do endocrine changes affect the voice?
- Endocrine changes can affect the larynx during development
- Larynx will not grow and the voice will be abnormally high
What is hypothyroidism?
-Improper secretion of hormones
What is a granuloma?
When there is a lesion of ulcer and the body tries to repair itself by growing granulation tissue over it
