quiz 3 Flashcards
voice evaluation part 2
1
Q
laryngoscopic observations
A
- VF edges
- glottic closure
- amplitude of VF vibration
- mucosal wave
- vertical level approximation
- supraglottic activity
- VF mobility
- phase closure
- phase symmetry
- non-vibrating phonation
- regularity
2
Q
vocal fold edges
A
- inspect free edge of VF for smoothness, straightness, or presence of lesions
- can be seen by telling someone to sniff 3x
- does not require stroboscopy
3
Q
glottic closure
A
- how do VF approximate during closed phase of vibration
- observe glottis at point of maximum closure
- rated at normal pitch and loudness
- closure configurations: complete, hourglass, spindle-shaped, incomplete, irregular
- requires stroboscopy
4
Q
amplitude of vibration
A
- how far do VF move laterally from midline during phonation
- should travel 1/2 visible width
- can be affected by fundamental frequency
- requires stroboscopy
5
Q
mucosal wave
A
- how far do VF move laterally from midline during phonation
- VF should travel 1/2 visible width in medial to lateral direction
- can be affected by fundamental frequency and intensity
- requires stroboscopy
6
Q
vertical level approximation
A
- do VF meet on same vertical plane
- one may overlap another
- does not require stroboscopy
7
Q
supraglottic activity
A
- look for lateral, medial, anterior, posterior involvement of supraglottic structures
- rated at normal pitch and loudness
- does not require stroboscopy
8
Q
vocal fold mobility
A
- VF abduction and adduction is assessed for paralysis/paresis
- mobility may be described as normal, limited abduction, limited adduction, fixed
- if fixed, may be described as in midline, paramedian, or lateral position
- does not require stroboscopy
9
Q
phase closure
A
- observe if VF are open and closed the same about
- should be equal
- requires stroboscopy
9
Q
non-vibrating portion
A
- immobility of any part of membranous VF
- estimate is made about % of VF not vibrating
- requires stroboscopy
9
Q
regularity of VF
A
- consistency of duration of successive cycles of VF vibration
- inconsistency = aperiodicity, VF will look blurry
- requires stroboscopy
10
Q
phase symmetry
A
- degree which VF appear to be mirror images of each other
- usually seen on onset or offset of phonation
- requires stroboscopy
11
Q
auditory-perceptual assessment and it’s challenges
A
- define presence of voice disorder clinically
- super subjective
- vocal parameters to be rated must be defined
- rater agreement, reliability, and validity must be determined
- rating method or scales must be created
12
Q
breathy voice quality
A
- whispery or airy
- hypoadduction
- periodic vibration
- incomplete closure
13
Q
harsh-rough voice quality
A
- raspy
- hyperadduction
- aperiodic vibration
- complete closure
