Laryngoscopic Observations Flashcards
1
Q
Vocal Fold Egde
A
- inspect the medial (free) edge of vfs. Make judgments about: smoothness, straightness, presence of mass/pathologies
- does NOT require stroboscopy; can be done with regular light
2
Q
Glottic Closure
A
- how do vf approximate during closed phase of vibration
- rated during normal pitch/loudness
- NEED stroboscopy
3
Q
Amplitude of Vibration
A
- how far do the vfs move laterally from midline during phonation
- can be affected by fundamental frequency and intensity
- NEED stroboscopy
4
Q
Mucosal Wave
A
- ripple like movements of the mucosa over the vfs
- assessed during normal pitch and loudness
- does NOT need stroboscopy; can be assessed using normal light
5
Q
Vertical Level Approximation
A
- do the vfs meet on the same vertical plane
- does NOT need stroboscopy
6
Q
Supraglottic Activity
A
- look for medio-lateral and antero-posteior involvement of supraglottic structures
- rated during normal pitch and loudness
- does NOT need stroboscopy
7
Q
Vocal Fold Mobility
A
- vd adduction/abduction assessed for paralysis/paresis of 1 or both vocal folds
- does NOT need stroboscopy
8
Q
Phase Closure
A
- observe amount of time vocal folds begin to part from midline, until lower lips of vfs approximate
- hypofunction = open
- hyperfunction = closed
- NEED stroboscopy
9
Q
Phase Symmetry
A
- refers to the degree to which the vfs appear to mirror images of each other while in motion
- NEED stroboscopy
10
Q
Non-Vibrating Portion
A
- immobility of any part of the membranous vf
- NEED stroboscopy
11
Q
Regularity
A
- refers to the consistency of the duration of successive cycles of vf vibration
12
Q
Overall Laryngeal Function
A
- refers to whether vibratory patterns are: normal, hypo-functional, hyper-functional, tremulous, spasmodic
13
Q
Observations that NEED Stroboscopy
A
- Glottic Closure
- Amplitude of Vibration
- Phase Closure
- Phase Symmetry
- Non-Vibrating Portion
