HC 3: Assessment: non-instrumental CSE Flashcards
Out of which components does the CSE exist?
- (Head/neck) physical examination
- clinical observation
- direct physical evaluation of motor and sensory function -> cranial nerves
- Functional observation swallow
- instrumental evaluation
What is a successful swallow? What does it require?
= safe transport from mouth to stomach (nothing enters the airway)
- > head & neck structurs
- > coordination (sequence of events)
What are head & neck examination’s limitations?
- does not provide enough information to gain a complete understanding of the pathophysiology -> usually FEES or a dynamic videofluoroscopic swallow study required
- subtle abnormalities of sensation & motor functions: not noticeable
- complex coordination: not all of it is examined
What does the head/neck physical examination consist of?
- face: asymmetries, signs of trauma, facial musculatore & sensation
- nose
- lips (as it is the 1st valve): saliva leakage? complete closure at rest? evaluate sensation & competence
- 2/3 chambers of the swallowing mechanism: oral cavity & oropharynx
- neck: palpation (for abnormal masses, large thyroid goiters, adenopathy)
- larynx: palpation (normal laryngeal structure, tethering?)
What do we examine in the oral cavity?
- interincisal distance (trismus?)
- move and look at the structures
- dentition (caries, broken, missing teeth? -> difficulty with bolus preparation)
- mucosal surfaces: no irregularities or lesions, moisture?
- saliva quantity & quality? Lack of saliva: no adequate bolus lubrication + oral/pharyngeal residue
- tongue: mobility & strength, surface irregularities, fasciculations, atrophy, tethering, palpation for masses
- cheeks: pocketing if weak
- hard palate: defects causes escape of air/bolus
- floor of mouth: lingual sulci -> tethering tongue?
What’s the role of the tongue in effective swallowing?
- during bolus preparation:
- base of tongue contact soft palate => prevents premature movement of the bolus to the pharynx
- moves the bolus between the teeth during mastication
- moves bolus into the pharynx
What’s the role of the soft palate in swallowing?
- prevents premature movement of the bolus into the pharynx (together with tongue base)
- aids in pressure generation to start bolus movement into the pharynx
- closes off the nasopharynx during the pharyngeal phase of swallowing
What do we examine in the oropharynx?
- visual inspection of:
- mucosal surfaces (masses, ulceration?)
- tonsils (enlarged?)
- symmetrical elevation of soft palate
- hypopharynx inspection by indirect or flexible laryngoscopy
What does the head and neck physical examination gives you information about?
- Obvious tumor, surgical changes, anatomic abnormalities
- Abnormalities of tongue, palatal and vocal fold mobility
- Inadequate sphincteric functions (oral, velopharyngeal and laryngeal)
- Loss of sensation
- Pooling of secretions
What will we be observing during the CSE? Why?
Because this information is needed for instrumental evaluation:
- overall condition & cognition
- level of awareness, alertness and cooperation, accept food voluntarily -> ready for instrumental study?
- apparent strength and potential for fatigue
- Body tone, oral tone, sitting position (postural support required? -> important for radiography)
- airway status: tracheostomy tube? breathing audible?
- ability to follow instructions
- self feeding potential: independently? special utensils needed?
What will we evaluate directly in the oral phase?
- structures
- sensation
- reflexes and responses/nonvolitional movements
- volitional movement
- oral sensorimotor integrity
- secretions
- articulation
- resonance
Explain direct physical evalution of the structure in the oral phase?
−Jaw, dentition (!molars), lips, tongue, buccal cavity, gum, faucial pillars, palate and velum à observe carefully
−Tissue condition: color, configuration, shape, size, symmetry, scarring or tethering
−Tonsils: presence/absence, size, placement and condition
Explain direct physical evalution of the sensation in the oral phase?
- assessing by applying light touch to lips, tongue, buccal cavity, gums,…
- hypersensitivity?
- reduced sensitivity?
- unilateral differences?
=> consequences for bolus management and trigger for swallow
Which nerves are involved for the taste and sensation in the oral phase?
- anterior 2/3 tongue:
- taste: VII
- sensation: V
- posterior 1/3 tongue: taste + sensation: IX
- facial sensation: V
- pharynx: IX (glossopharyngeus)
Explain direct physical evalution of the reflexes and nonvolitional movements/responses in the oral phase?
- gag reflex = normal oral reflex
- > check presence
- > check symmetry
- suggestion for neurological problems if
- impairment of reflexes
- presence of primitive reflexes
