Q

Requirements for Oral Prep / Oral Stage

A

Lip Seal: prevents anterior leakage / spillage
Buccal tension: keeps food from lower buccal cavities
Lingual ROM: keeps food from slipping out of control – holds bolus against hard palate; prevents posterior spillage; aids in mastication
Hard Palate: provides roof to control and manipulate bolus
Soft Palate Seal: prevents nasal regurg and posterior spillage

Residue on tongue due to reduced tongue ROM or strength or poor sensation
Adherence of food to hard palate due to reduced tongue elevation or poor strength
Poor bolus movement anterior to posterior due to reduced lingual coordination

Q

Pharyngeal paresis/paralysis

A

Look for movement of the PPW, lateral pharyngeal walls
Asymmetry of bolus movement
Strong side pushes the bolus across midline to the weaker side, so the bolus passes down the weak side
Usually due too neurogenic issues

18
Q

Hyoid Elevation and Laryngeal Movement

A

Abnormal elevation:
No elevation
Poor elevation
Elevation occurs, but unable to be sustained

19
Q

Epiglottic Inversion

A

Normal epiglottic tilt is a 2 step process

  1. Passively moves horizontally by hyoid elevation and posterior movement of the tongue
  2. Contraction of the thyroepiglottic muscle further inverts the epiglottis
20
Q

Delay

A 
Sensation issue
Swallow triggers “lower down” than typically noted
Mild:  Vallecula
Moderate:  Vallecula / Pyriforms
Severe:  Pyriforms
Prolonged pooling in these areas = delay
21
Q

Premature spillage =

A

Incompetence of the palatoglossal seal and is characterized by movement of the bolus posteriorly, without cohesive organized intent, prior to the onset of a swallow reflex.
Premature spillage is attributed to weakness and / or poor coordination of the posterior tongue or the soft palate or both

22
Q

Delay =

A 
Typically sensation related
“hold the food in your mouth until I say swallow”
Residue
Mild, moderate, or severe amounts (SLP subjective) of the bolus can retained in the vallecula or pyriforms after the swallow, or posterior pharyngeal wall
Can be due to: Weakness
Poor base of tongue retraction
Reduced pharyngeal constriction
Poor pharyngeal coordination
Poor UES opening
Penetration
Entry of the bolus into the laryngeal vestibule above or to the level of the vocal folds
DOES NOT pass through the vocal folds
23
Q

Levels of Penetration

Highest to lowest

A

Epiglottic
Tip of the epiglottis, inferior surface
Aryepiglottic folds, False vocal folds
True Vocal Folds

24
Q

Penetration Can Occur:

A 
Before the Swallow:
----Due to premature spillage or delay
During the Swallow:
----Due to poor coordination, laryngeal closure issues
After the Swallow:
----Due to residue
25
Q

Aspiration

A

Entry of the bolus BELOW the level of the vocal folds- into the airway
Occurs if there is failure of the laryngeal protective mechanisms
Hyolaryngeal elevation, epiglottic inversion, laryngeal closure

26
Q

Aspiration Can Occur:

A

efore the Swallow
—–Due to premature spillage or delay
During the Swallow
—-Due to laryngeal incompetency and closure issues
i.e. TVC issues, poor epiglottic inversion
After the Swallow
—–Due to residue or reflux

27
Q

How is Aspiration Normally Prevented?

A

Prevention of premature spill
Prompt and organized transfer of food through the oral cavity and pharynx owing to timely and forceful contraction of the posterior tongue and the sequential contraction of the pharyngeal muscles and prompt opening of the UES as part of the sequential swallow

28
Q

Coordination of swallowing with respiration

Protective reflexes against aspiration including:

A

Laryngeal elevation, lifting up and forward movement of the larynx so as to move out of the way and “hide” under the epiglottis and the tongue during a swallow
Reflexive closure of the larynx true and false vocal cords along with the AE folds
Epiglottic inversion helps direct bolus around the airway during swallowing

29
Q

If these fail and the bolus enters the trachea, a strong cough reflex is normally triggered.

A

Airway clearance can also be achieved later by the mucociliary elevator (cillia)!
Laryngeal Adduction Reflex

30
Q

Audible Aspiration

A

Both penetration and aspiration are “audible” in the normal population
Clinically indicated by a reflexive cough or throat clear

31
Q

Silent aspiration

A

Not all penetration and aspiration is audible, voice, neurogenic, ventilator, teach
Typically, do not know they are aspirating because they do not cough or clear their throat
Clinical prediction of silent penetration/aspiration is notoriously inaccurate!
voice quality, breathing, caught

32
Q

Factors to Consider about aspiration 
 Quantity

Larger quantities of material is riskier than aspiration of smaller, more minute quantities

A

Depth
How far does aspiration travel down trachea?
Just below vocal folds? Into distal airways?
Further down aspiration = more dangerous
Physical Properties of the Aspirate
Thin liquids easier to clear
Solids can obstruct airway and be fatal
Acidic material from reflux is dangerous (lungs highly sensitive to caustic acid=pnemonia)
Aspiration of saliva from oral cavity can be dangerous if saliva contaminated with infectious organisms (poor oral care)
Lungs can tolerate aspiration of water much better than anything else

33
Q

Pulmonary Clearance Mechanism

A

Strong and productive cough?
Other pulmonary issues?
Bed bound? Walkie-talkie?
Smoker?

34
Q

Penetration / Aspiration Scale

A

Score Description of Events 

 1 Material does not enter airway
2Material enters the airway, remains above the vocal folds, and is ejected from the airway.
3 Material enters the airway, remains above the vocal folds, and is not ejected from the airway.
4Material enters the airway, contacts the vocal folds, and is ejected from the airway.
5Material enters the airway, contacts the vocal folds, and is not ejected from the airway.
6Material enters the ariway, passes below the vocal folds, and is ejected into the larynx or out of the airway.
7Material enters the airway, passes below the vocal folds, and is not ejected from the trachea despite effort.
8 Material enters the airway, passes below the vocal folds, and no effort is made to eject.

35
Q

Esophageal Stage Impairments
Can result in retention of the bolus in the pharynx or esophagus
May be a result of:

A 
Mechanical obstruction
CP bar, stricture, osteophyte
Weakness
Motility Disorder
Impairments of the UES or LES
36
Q

S/sx Esophageal Dysphagia

A 
Globus sensation
Change in dietary habits
Reflux
Coughing up particles of undigested food
Pyriform sinus pooling
Diverticulum
Unexpected weight loss
Recurrent pna
Difficulties with pills 
increased mucus production
trachesophageal
37
Q

CP Bar

A

The UES is an area that is longer than the cricopharyngeus and consists of a zone of high pressure consisting of some fibers of the inferior constrictor muscle, the cricopharyngeal muscle, and some circular fibers of the proximal cervical esophagus.
fails to relax and open, the bolus may have difficulties passaging from the pharynx to the cervical esophagus
Opening is the physical separation of the walls (of the sphincter), whereas relaxation is loss of tension or loosening

38
Q

CP Bar

A

UES is seen videofluoroscopially as “sticking out” posteriorly – known as a CP bar
Thumb-like indentation
Can be obstructive or nonobstructive

39
Q

Diverticulum

A

An “outpouching” of the tissue forming an opening for material to gather in the esophagus
Usually forms in an area of weakness
Zenker’s most common

40
Q

Zenker’s most common

Manifests itself as:

A

Dysphagia
Globus sensation
—–May fill up with food, causing the person to cough up partially ingested food into the mouth
Halitosis
—-Potential infection of the pharyngeal areas due to food stuck
Involuntary gurgling noises when swallowing
Rarely causes any pain

41
Q

Cervical Osteophyte

A

More than half of the people over the age of 60 have osteophytes, or bone spurs
Osteophytes in the spine are a normal sign of aging and are not a cause for concern unless they result in pain or neurological symptoms

42
Q

Cervical osteophytes

A

are bone spurs that grow on any of the seven vertebrae in the cervical spine
Cervical Osteophyte formation
Typically occurs when ligaments and tendons around the bones and joints in the cervical spine are damaged or inflamed.
The inflamed or damaged tissue abnormally influences surrounding bone growth (though hard, bones are constantly renewing, like fingernails and hair).
As a result, new bone cells are deposited where they would not normally grow.

43
Q

Frequently Used Terms

A 
Retrograde bolus movement
Slowing of the bolus
Posterior prominence (CP bar)
Obstructive in nature
Congruent with (osteophyte, narrowing of the esophagus, etc.)
Backflow
Reduced clearance
Stasis
Outpouching
