Lesions of VC Flashcards
(56 cards)
3 classifications of voice disorders and pathologies
- functional
- neurological
- organic
Functional disorders
a. Types of functional disorders (6)
- Not organic or neurological
- Has to do with the way the VF move, but nerve function is intact
a. functional aphonia (loss of voice without organic cause, usually caused by emotional stress)
b. paradoxical vocal fold movement (PVFM)
c. muscle tension dysphonia (MTD)
d. ventricular phonation
e. traumatic laryngitis
f. puberphonia- voice changes in puberty
- Functional issue- do a videostroboscopy, look at movement of VF in slow motion- can see bowing (not neurological)
- Neurological disorders (2)
2. Neuro conditions
- vf paralysis
- spasmodic dysphonia

Lesions of VF
Produce pathological changes such as:
- Increasing Mass (alter shape)
- Altering Shape
- Restricting Mobility
- Increasing or Decreasing Tension
a. Can be unilateral or bilateral
b. Nodules usually bilateral
c. Polyps are usually unilateral
*** if gap, breathy escape

CRI du CHAT VOCAL CHARACTERISTICS
5
- High pitched, mewing cry
- Painful cry
- Flat or rising melody patterns
- Strained quality (larynx is abnormal)
- Crying on inhalation with inhalatory stridor (some type of obstruction or VF more in the midline)
Bacterial, Viral and Fungal Infections
A. Cause: (2)
B. Result from: (5)
A. Cause
- Respiratory Distress
- Airway Obstruction
B. Result from
- Result of herpes simplex virus
- Croup viral due to influenza virus affects children between 3 months and 3 years of age
- Inflammation and edema in the subglottal area
- Epiglottis bacterial
- Candidiasis fungal
Fungal laryngitis
There is a central white coating that can be quite thin with a surrounding erythema. It seems to be most frequently associated with ADVAIR HFA Inhalers (fluticasone propionate and salmeterol)
Candidiasis
Candidiasis or thrush is a fungal infection commonly referred to as a yeast infection
- fungal infection are more likely to occur when the immune system is suppressed like after chemo
- Coccidomycosis is from Cali’s central valley
Bacterial infection
1. Epiglottitis
A bacterial infection of the larynx is very serious as the swelling can nearly close off the airway in an adult and easily closes off the airway in a child. It is typically called epiglottitis or supraglottitis. The danger lies in the softness of the tissue which can easily expand, particularly the loose tissue of the arytenoids can be drawn in during inspiration. Here the arytenoids are very swollen and limiting the opening of the vocal cords. (closing off the airway)
- typically improves with antibiotics
Inflammation/Laryngitis
- Inflammation of the larynx
- Anterior is the apex
- Posterior is where the arytenoids are
- Vocal quality:
a. Drop the pitch
b. Deep pitch
c. Soft intensity
d. Vocal quality- breathy, hoarse, strained (loud, moderate, or severe)
e. Most lesions will occur on the edge of the VF
Viral Infections (4)
- common cold- makes VF pink and swollen, voice deep, and secretions thick
- Laryngitis sicca- laryngeal dryness, possibly related to autoimmune disease
- Herpes Simplex Virus- HSV1 produces most cold sores
- HSV2 produces most genital herpes
- Watery blisters in the skin or mucous membrane - Viral laryngitis- unilareral edema, diplophonia, hoaseness (breathy and harsh)
- plain harshness (no breathiness)
Viral Coup
- Viral Croup
- Most common form of airway obstruction in children 6 months to 6 years old
- Respiratory tract infection causes an upper airway obstruction causing:
a. Barking cough
b. Horse voice
c. Inspiratory stridor
d. Wheezing
e. Treated with epinephrine
Laryngeal Papilloma
- Location
- Size
- Etiology
- Vocal Symp.
- Managment
- on or around VF
- wart like
- thought to be viral, but uncertain
- a. Breathiness
b. tension
c. aphonia
d. hoarseness - Med surg. w/ Voice therapy (keep occuring)
Congenital Laryngomalacia
- Redundant arytenoid cartilage mucosa (too much)
- Epiglottis omega shaped
- Aryepiglottic folds sucked into glottis on inhalation
- Aryepiglottic folds blown out on exhalation
- Symptoms resolve spontaneously within 6 to 18 months
- Other Associated Problems
a. Gastroesophageal Reflux
CONGENITAL LARYNGOMALACIA VOICE CHARACTERISTICS
- Congenital laryngeal stridor described as high pitched harsh and fluttering
a. Becomes worse with crying and feeding - Swallow study needed to rule out aspiration pneumonia
- Can’t see VF, collapsing of epiglottis gives it a strange fluttering sound
***Can occur in peds and adults, can cause an arytenoid to be dislocated
Congenital Laryngeal Web
- Location
- Etiology
- Vocal Symptoms
- Managment
- General includes the anterior commisure and can extend the length of the VFs
- attachment can be infra and supra glottal as well as cordal - congenital or acquired
- a. elevated pitch
b. tension
c. diplophonia
d. hoarseness–> aphonia - stridor
- combination of surgery and voice therapy (web can be caused by anything that damages the larynx) (fumes, burn, or injury)
Congenital posterior glottic web
- can be anterior, middle or posterior
Congenital subglottal stenosis
- Below the glottis, below VF
- Respiratory problems- may need a trach immediately, kids may need to be on permanent trachs
- Arytenoids sit on the back of the cricoid cartilage
- Arrested embryonic development of conus elasticus
- Maldevelopment of the cricoid cartilage
- Obstructive narrowing of the airway
- Voice normal to impaired
- Stridor present from birth
- May require tracheostomy
* ** narrowing
- can also have congenital tracheal stenosis
Different types of breathiness (2)
- Hyperfunctional- harshness, straining (pushing too hard)
2. Hypofunctional- weakness, lethargic (try to see if they can get them together)
Congenital Laryngotracheal Cleft
- Embryonic failure of dorsal cricoid lamina fusion
- Results in an interarytenoid cleft and open larynx posteriorly
- Cry weak or aphonic due to cleft preventing apposition of the vocal folds
- Aspiration pneumonia
- Feeding problems
- VF are formed properly in the front, open in the back
Congenital Cysts
Cysts- congenital cysts- unilateral, midline of fold, embedded in the fold (within the body of the cord)
- Congenital saccular and ventricular cyst - make sure you can tell the difference between vibrato and tremor
- most likely causes hyperfunctional breathiness and deep pitch
