Exam 2 Part 12 Flashcards
The sharper and and steeper the maximum flow declination rate, what will happen?
Brighter and louder the sound is going to be, more vocal fold collision forces
Provides more information about the severity and nature (possible etiology) of a voice disorder than other instrumental measures.
Laryngeal imaging
What 3 things do we look at during laryngeal imaging?
Structure, movement, function
What are the 3 types of laryngeal imaging?
Stroboscopy (most common clinically), kymography, high speed
What are the 2 types of laryngeal endoscopes?
Flexible, rigid
Goes through the oral cavity and oropharynx
Rigid
Goes through the nasopharynx
Flexible
What are the 2 flexible/rigid scopes?
Stroboscopy
What are the 2 rigid scopes?
Kymography, high speed
What are the benefits of rigid endoscopy?
Close view and better lighting to the image due to fiberoptic bundles, avoids optical artifacts due to larger magnification
What are the disadvantages of rigid endoscopy?
Can only say /i/, unnatural positioning for speech
What are the benefits of flexible endoscopy?
Can view the larynx during connected speech tasks and allows a broader view of vocal tract and supraglottic region, visual biofeedback during treatment
What are the disadvantages of flexible endoscopy?
Darker image due to diameter of fiber optic lights, difficult to achieve a stable image during connected speech, risk of nosebleeds
What changes in larynx are typically seen secondary to presbylarynx?
Vocal atrophy or thinning of vocal folds (loss of tissue bulk), prominent appearance of vocal processes are seen, degeneration of the TA muscle, decreased elasticity and increased stiffness
Degeneration of the vocal folds is seen especially in the _____ layer of lamina propria.
Intermediate
What is the shape of glottic configuration typically seen in presbylaryneus?
Spindle and vocal fold bowing
“Structural pathologies such as vocal nodules change the biomechanical properties of vocal folds, and therefore their function”. Explain this statement.
Structural pathologies add mass to the tissue and also unwanted/additional tension to the tissue. Changes in tissue’s biomechanical properties leads to physiological changes such as voice quality, loudness, and pitch.
Fundamental frequency and its harmonics depend on _____, ______, and ______ of the tissue.
Length, mass tension
Vocal tract tuning to improve the brightness of the sound, instead of increasing the vocal effort and tension is an example of ________ type of compensatory adjustment (productive / maladaptive).
Productive
Assume that you are a voice pathologist working in an outpatient voice clinic with an otolaryngologist. He sent you a patient for a laryngeal endoscopy. After performing the procedure, you clearly know that the patient has bilateral vocal fold nodules. How do you write the diagnosis in the report?
Bilateral (gelatinous if acute or fibrous if chronic) masses seen on the medial edge between the anterior 1/3rds and posterior 2/3rds of true vocal folds.
