Test 3 Flashcards
(42 cards)
Strengths of MBS
- “Gold standard”
- Most comprehensive view available
- Follow bolus from oral cavity to esophagus
- Non-invasive
- Vallecula and pyriform sinuses (%) “guess”
- Widely practiced and accepted
Limitations of MBS
- Radiation exposure
- Unnatural replication of eating (taste & viscosity)
- Positioning may be difficult (e.g. obese; movement disorders, agitation ataxia)
- Staffing and scheduling requirements (Varies by facility: Physician; radiologist; SLP)
Strengths of FEES
- Objective info when MBS is unavailable
- View mucosal surface
- View post-surgical changes
- Observe laryngeal function/airway protection
- Observe available secretions and dryness
- View events before & after swallow
Limitations of FEES
- Invasive, uncomfortable/painful
- No set criteria for “mastering” procedure (but MUST have physician on site
- Need to infer disordered physiology of swallow (Epiglottis gets in the way of seeing the actual swallow)
- Can’t see UES/PES function during swallow
- Can’t see esophagus
- White out: epiglottis comes over
- Gunking: secretions on camera
- Anatomy variation can limit view
- Allergy to blue dye (Use green now)
List 6 structures you could see during an MBS.
Hyoid bone, Epiglottis, Valleculae, True vocal folds, Pyriform sinuses, UES/PES

- head rotation and chin tuck
- lie down
List sensory techniques used in dysphagia therapy.
- carbonated bolus
- sour bolus
- textured bolus
- thermal-tactile stimulation
List voluntary controls used in dysphagia therapy.
- super supraglottic swallow

- Effortful swallow
- Mendelsohn maneuver
List strengthening exercises used in dysphagia therapy.
- Masake’s technique
- Showa maneuver
- Shaker exercise
- Tongue strengthening
- Range of motion
Postural change- Chin tuck:
- Decreases distance between tongue base and pharynx
- Narrows airway entrance
- Widens vallecula
- Directions: Tuck your chin as close to your chest as possible and swallow
Postural change- Head rotation:
- Usually used for stroke patients
- Closes weaker side of pyriform sinuses
- Directs food to stronger side
- Pushes VFs together (for extra protection)
- Directions: Chew up your food and when you’re ready to swallow, turn to [weaker side] and swallow
Postural change- Head rotation and chin tuck:
- For weakness and penetration
- Directions: Chew up your food and when you’re ready to swallow, turn to [weaker side], tuck your chin as close to your chest as possible, and swallow
Postural change- Chin elevation:
- Uses gravity
- Requires rapid triggering of pharyngeal phase
- Need good airway protection
- Directions: Lift chin up and swallow
Postural change- Lying down:
- Gravity affects residue
- Consider if residue is in pharynx after swallow
- Due to poor laryngeal elevation
- Poor B/L pharyngeal contraction
- Must cough before sitting up (to clear)
- Ex: MS
Sensory techniques- Carbonated bolus:
- alka-seltzer or other
- Increases speed of swallow
- Alternate between carbonated and regular liquid
Sensory techniques- Sour bolus:
- ½ lemon juice, ½ water/barium
- Increases speed of swallow
- Alternate sour and regular liquids
Sensory techniques- Textured bolus:
- Add solids to puree or liquids
- Put solids in gauze with floss attached
- Chewing practice
- Taste stimulation
- Nerves in mouth are stimulated to various textures
Sensory techniques- thermal-tactile stimulation:
- Evidence questionable
- cold Laryngeal mirror against anterior faucial arches
- Swallow
- Increases rate of pharyngeal phase
- Caution if hyper gag reflex
Voluntary control- super supraglottic swallow:
-Closes airway before and during swallow
-Speeds onset of laryngeal elevation
-Take breath, hold it, and bear down (like going to the bathroom) and swallow… cough to clear any residue
E.g. vocalize and stop vocalizing - hold it to feel (“bearing down”)
Voluntary control- supraglottic swallow:
- Closes airway at VFs before and during swallow
- Take breath, hold, and swallow… cough to clear any residue
Voluntary control- effortful swallow:
- Increases pressure by tongue and tongue base during swallow
- Reduces residue in pharynx (practice contraction)
- Squeeze hard with tongue as you swallow; exaggerate your swallow
Voluntary control- Mendelsohn maneuver:
- Increase laryngeal elevation
- Increase width of cricopharyngeal opening
- I’m going to have you swallow but catch it (hold breath) halfway through, hold it for 3 seconds then relax. Swallow and feel your voice box lift. When it reaches its highest point, hold it for 3 seconds, then relax
Strengthening exercises- Masake’s technique
- Works glossopharyngeal muscles
- Hold front of tongue between teeth and swallow hard
- Feel muscles of pharynx and slight pharyngeal delay
- DO NOT use food or liquids
Voluntary control- Showa maneuver:
-Targets base of tongue and larynx
Pull tongue straight up and back in mouth
Yawn and hold when tongue is farthest back
Pretend to gargle and hold tongue when farthest back
