True or False, the ventricular or false vocal folds lie below the true vocal folds.
|
False
|
|
Damage to which nerve leads to difficulty adducting the vocal folds?
|
Recurrent laryngeal nerve of cranial nerve X
|
|
What is the difference between jitter and shimmer?
|
Jitter or frequency perturbation refers to the variation of vocal frequency, while shimmer or amplitude perturbation refers to the cycle to cycle variation of vocal intensity.
|
|
List the perceptual qualities a clinician uses in evaluating a patient's voice.
|
Pitch, volume, vocal quality, resonance, respiration and ability to sustain phonation.
|
|
What is a localized inflammation that is composed of granular tissue in a firm rounded sac is called what?
|
Granuloma.
|
|
What instrument uses a pulsating light for perceived slow motion in viewing the vocal folds?
|
Stroboscopy
|
|
What does the Blom-Singer device do?
|
The Blom-Singer device shunts air from the trachea to the esophagus so the patient can speak on that air.
|
|
What is diplophonia?
|
Diplophonia is a term that refers to double voice.
|
|
Which muscle is a chief vocal fold tensor?
|
Posterior cricothyroid muscle
|
|
List the vocal fold adductors.
|
1. Thyroarytenoid muscles
2. Lateral cricoarytenoid muscles 3. Transverse and oblique interarytenoid muscles |
|
What is the function of the extrinsic muscles of the larynx?
|
They help stabilize and alter the position of the laryngeal skeleton during respiration, deglutition and swallowing.
|
|
Where do most benign laryngeal pathologies such as vocal fold polyps, nodules and cysts develop?
|
They develop in the superficial layer of the lamina propria.
|
|
What is the aging of the laryngeal structures is called?
|
Presbylaryngis
|
|
What can mucosal irregularities caused by scarring, atrophy secondary to vocal fold paralysis be treated with.
|
Bovine collagen injections.
|
|
What are the benefits of the Visi-Pitch device?
|
Visi-Pitch device is helpful in providing biofeedback of nonvocal airflow control and various sound parameters.
|
|
Which instrument uses surface electrodes placed on the thyroid cartilage and high frequency electric current while the patient phonates?
|
Electroglottography
|
|
In accessing the respiratory status of a patient for voice, what types of breathing does the clinician analyze?
|
1. Clavicular breathing: patient inhales and shoulders elevate.
2. Diaphragmatic-abdominal breathing - using the abdominal region and lower thoracic cavity - used by professional singers 3. Thoracic breathing |
|
True or False. Hypernasality is when nasal resonance is absent on nasal sounds.
|
False
|
|
What is the purpose of the s/z ratio phonation time?
|
The s/z ratio determines whether there is a laryngeal pathology present.
|
|
List the vascular supply of the larynx.
|
Superior laryngeal, cricothyroid and inferior laryngeal arteries.
