1
Q

Dysphonia

A

Voice disorder characterized by auditory perceptual symptoms

2
Q

Organic Voice Disorders

A

Can be structural or neurogenic

3
Q

Structural Voice Disorder (Organic)

A

Physical changes of the vocal mechanism

Cysts, growths, trauma to larynx, contact ulcers, nodules, edema, lesions, laryngitis, hemorrhage, glottal stenosis, sarcopenia

4
Q

Neurogenic Voice Disorder (Organic)

A

Innervation to structures is impaired/damage

Spasmodic dysphonia, Parkinson’s disease, Myasthenia gravis, ALS, essential/vocal tremor, paralysis/paresis of vocal folds

5
Q

Functional Voice Disorders

A

Can be misuse or psychogenic

6
Q

Misuse Voice Disorder (Functional)

A

Normal structure, improper use/misuse

Muscle tension dysphonia, vocal fatigue, diplophonia, hypofunctional (incomplete VF closure), hyperfunctional (overuse)

7
Q

Psychogenic

A

Normal structure, psychological cause

Conversion dysphonia, conversion aphonia, puberphonia (i.e., mutational falsetto), depression, anxiety, stress disorders

8
Q

Voice Disorder Assessment

A

Case history, auditory evaluation, perceptual evaluation, oral motor exam, respiration, articulation, resonance, instrumental imaging

9
Q

Informal Assessments

A
  1. Characteristics of voice (acoustic/perceptual)
  2. Resonance
  3. Respiration
  4. Intelligibility
10
Q

Hypernasal Resonance

A

Excess air through nasal cavity, during production of all sounds besides nasals /m, n, ng/

11
Q

Hyponasal Resonance

A

Note enough air through nasal cavity during production of nasal consonants; blocked air

12
Q

Cul-de-sac Resonance

A

Sound is trapped in oral, nasal, or pharyngeal cavity; muffled/low voice

13
Q

Mixed Resonance

A

Co-occurrence of hypernasality, hyponasality, and/or cul-de-sac resonance

14
Q

VP Dysfunction

A

VP valve does not close completely during the production of oral sounds

15
Q

VP Insufficiency

A

VP dysfunction due to anatomical/structural defect

16
Q

VP Incompetence

A

Poor movement of structures

17
Q

VP mislearning

A

Poor closure due to mislearning

18
Q

Pitch

A

Acoustic Evaluation: pitch determination (fundamental frequency)

Perceptual Evaluation: pitch characteristics; perceived high/low tone, pitch level, pitch variations, pitch breaks, tremor

19
Q

Loudness

A

Acoustic Evaluation: Measures intensity level; sound level meter or computer program (PRAAT)

Perceptual Characteristics: loudness characteristics; loudness level and variation in loudness

20
Q

Quality

A

Acoustic Evaluation: jitter (frequency perturbation), shimmer (amplitude perturbation), s/z ration

Perceptual Evaluation: percieved pleasantness; breathy (air escaping between vocal folds), harsh (hard, glottal attacks, low pitch, hypo/hyper loduness), hoarse (combo of breathy and harsh qualities), rough; strained and strangled gurgly and wet, phonation breaks, glottal fry etc.
