5.1 Functional Voice Disorders Flashcards
(33 cards)
Functional Voice Disorder
-Primarily related to the way the voice is used
-Phonotraumatic Behaviors
Phonotraumatic Behaviors
Vocal Misuse and abuse
Phonotraumatic Behavior Examples
- Hard Glottal Attack
- Laryngeal Squeezing
- Persistent Glottal Fry
- Excessive Talking/Talking too loudly
- Excessive Coughing/Throat Clearing
- Yelling/Screaming/Making Unusual Sounds
Functional Voice Disorders Predisposing Factors
- Vocal Demands
- Allergies, GERD (LPR)
Are structural changes secondary to phonotraumatic behaviors?
Yes
Muscle Tension Dysphonia Definition
1.Excessive laryngeal musculoskeletal tension of extrinsic or intrinsic muscles
- Hyperfunctional disorder
MTD Contributing Factors
- Anxiety
- GERD
- Infection
- Edema
Primary MTD vs. Secondary
Primary has no other underlying cause, Secondary has an organic underlying cause
MTD Auditory-perceptual & acoustic characteristics
- Strained Voice
- Decreased loudness level and range
- Pitch variable but decreased range (High pitch has an elevated laryngeal position and increased VF tension)
MTD Aerodynamic characteristics
Increased laryngeal resistance
MTD Laryngeal Imaging Characteristics
- Supraglottic hyperfunction
*Increased medial compression of true and false VFs
*Anterior-posterior compression
MTD Management
- Behavioral Voice Therapy
- Voice Hygiene
Vocal Nodules
-Most common benign VF lesion (adults and kids)
-Callous-like swellings on inner margin of VFs
-Inflammatory degeneration of superficial layer of LP
-Basement membrane zone
-Usually bilateral and symmetrical
-Caused by phonotraumatic behaviors
Vocal Nodules Auditory-perceptual & acoustic characteristics
- Roughness & Breathiness
- Difficulty producing high pitched sounds & reduced pitch range
- Reduced pitch: Increased mass -> slower vibration -> decrease in F0
- Vocal Fatigue
a. increased voice use
b. Associated tension as compensation → strained voice quality
Vocal Nodules:
Laryngeal imaging characteristics
- Early or acute nodules: soft, pliable, reddish
- Chronic nodules: hard, white, thick, fibrotic
3.vLaryngeal and VF edema
- Hourglass closure patterns
- Decreased vibratory amplitude
- *Asymmetrical vibration
Vocal Nodules:
Aerodynamic characteristics
- Increased airflow
- Decreased subglottal pressure
Vocal Nodules: Management
- Behavioral voice therapy
- Vocal hygiene
- *Surgery
Vocal Polyp
- Small to large fluid-filled sacks
- Usually unilateral
- May create contralateral reaction
- Anterior 1/3 of VFs
Vocal Polyp Etiology
- phonotrauma
a. Gradual course
b. Can result from single event: yelling
c. Highly associated with smoking
Vocal Polyp
Auditory-perceptual & acoustic characteristics
- Roughness and breathiness
- Decreased pitch and pitch range
a.Diplophonia
3.Decreased loudness
a.Strained voice quality
- Vocal fatigue
a.Increased voice use
Vocal Polyp
Laryngeal imaging characteristics
- Sessile: closely adhering to mucosa, broad base
- Pedunculated: attached by a slim stalk
- Vascular, edematous, inflamed
- Hourglass closure pattern
- Aperiodic vibration and asymmetry
- Reduced vibratory amplitude and mucosal wave
Vocal Polyp:
Aerodynamic characteristics
- Increased Airflow
- Decreased subglottal pressure
Vocal Polyp Management
- Behavioral Voice Therapy
- Vocal Hygiene
- Surgery
Reinke’s Edema
- Buildup of fluids in Reinke’s space
a.Generalized edema - Highly associated with smoking (90% of cases)
a.Chronic mucosal irritation - Other terms: polypoid degeneration, chronic polypoid corditis
