Written Exam Flashcards
Advantages of FEES
- Unlimited time
- Can repeat as often as needed
- Portable exam; more accessible to patients
- Don’t need to put patient at risk for aspirating food/liquid
- Direct view; easier to localize spillage, residue
- Better understanding of some abnormal patterns
Disadvantages of FEES
- More limited view
- Technically more difficult to learn
- Some patients find it uncomfortable
- Cannot adequately assess oral phase of swallow
When is FEES exam indicated? (practical/easier to do)
- Patient is bedridden; weak
- Patient has contractures; in pain
- Patient is a quadriplegic, has neck halo
- Patient on cardiac monitors; in ICU
- Patient is on a ventilator
- Need exam that day
- Need repeat exam
- Concern about excess radiation exposure
- Corns about cost of fluoroscopy
Clinical findings better revealed endoscopically
- Incomplete TVD adduction, immobile vocal cord; reduced mobility of arytenoids
- Excess secretions; aspiration of secretions
- Residue building up over several swallows
- Impaired ability to adduct TVF
Advantages of fluoroscopy
- more comprehensive view
- easier to learn; administer
- better understanding of some abnormal patterns
Disadvantages of fluoroscopy
- radiation exposure
- time-limited exam
- inaccessible to some/many patients
- frightening, fatiguing, uncomfortable for some patients
- uses non-physiologic medium
- need to present food/liquid to assess
- more difficult to localize material; identify structures
- more costly
Clinical findings better revealed with fluoroscopy
- impaired tongue control and manipulation of the bolus
- impaired tongue force for bolus thrust
- impaired laryngeal elevation
- reduced cricopharyngeal opening
- reduced airway closure at level of arytenoid to epiglottal contact
- reduced esophageal motility
- aspiration during the swallow
Ability to assess therapeutic maneuvers: head turn/chin tuck
Fluoroscopy = good
FEES = excellent
Ability to assess therapeutic maneuvers: other body position-side lying
Fluoroscopy = fair
FEES = excellent
Ability to assess therapeutic maneuvers: alteration in bolus size, consistency
Fluoroscopy = excellent
FEES = excellent
Ability to assess therapeutic maneuvers: alteration in food delivery
Fluoroscopy = good
FEES = good
Ability to assess therapeutic maneuvers: effortful swallow
Fluoroscopy = excellent
FEES = fair
Ability to assess therapeutic maneuvers: supraglottic swallow
Fluoroscopy = good
FEES = excellent
Ability to assess therapeutic maneuvers: Mendelsohn maneuver
Fluoroscopy = excellent
FEES = good
Ability to assess therapeutic maneuvers: time to try all of these
Fluoroscopy = poor
FEES = excellent
Typical diameter of flexible scope
3-4 mm
Flexible endoscope allows for as much as a __ degree field of view
90
Distance distortion
if you get too close to a structure you are going to lose resolution, if you move further away you will get a crisper image but you wont see every detail
Radial distortion
because of the parallax effect – the center of the image will be the most accurate or symmetrical, and as you move away the angle of the scope the angle may make it look a little distorted
Transnasal placement of the laryngoscope will prevent visualization of the _____ stage of the swallow
oral
Major elements affecting optimum visualization
velar elevation
base of tongue contraction
clouding if the distal lens with bolus residue or oropharyngeal secretions
The velum contributes to both the oral and ________ swallow
pharyngeal
When the distal tip of the endoscope is placed within the hypopharynx, the velum will/will not be in view
will not
Movement of the velum contributes to changes in the visualizations of events _____, _____, and ______ the swallow.
before, during, and after
Scope position to maximize observation of velar function…
- Scope position should allow for a view of the mucosa covering the vomer bone at the left or right periphery
- You should see the superior surface of velum, contact of the velum with the posterior pharyngeal wall, and. the extent of elevation of the velum
