Q

what can voice quality tell you in clinical beside eval?

A
  • dysphonia (breathiness, hoarseness, harshness) is predictive of aspiration
  • wet vocal quality (hard to perceive)
  • reduced pitch elevation is predictive of higher penetration-aspiration scale scores

Q

what do you hear with cervical auscultation?

A

(hearing sounds of swallow with stethoscope)

should hear 2 bursts (bolus entrance into pharynx, leaving pharynx) ; 3rd small burst in some (glottal release)

delay in hearing these sounds could signify swallow abnormality

Q

why do pulse oximetry w clinical bedside?

A
  • measure oxygenation of peripheral blood flow (measures amount of light absorbed by blood in tissue, which varies w/ oxygen content)

95-100% normal rance, <90% suggests problems

some studies suggest 2% drop in SPO2 are not related to aspiration events but are more likely to be found in Pts symptomatic for dysphagia

Q

can clinical swallow tell us who aspirates?

A

no. clinical swallow gives us information on Pts who are at risk for aspiration and/or dysphagia. no info on bolus flow or swallow physiology (always remember natural variation).

Q

importance of cranial nerve XII (hypoglossal)

A

motor for all extrinsic and intrinsic muscles of tongue, except for the palatoglossus (X vagus)

18
Q

what could involuntary movements of structures during clinical swallow be a sign of?

A

hyperkinesia

19
Q

what signs of parkinsons would be observable in OME of face?

A
  • “mask” face

- lips tremor

20
Q

why make raise eyebrows during OME?

A

bc absence of forehead wrinkling = can differenciate UMN (bilat) vs LMN damage (unilat)

21
Q

what’s the name of restriction in opening of the jaw

A

trismus

22
Q

role of changes in pressure within oro-pharyngeal structures in a normal swallow?

A

allows the bolus to move rapidly from zones of high pressure to zones of low pressure.

(for example, laryngeal elevation creates negative zone of pressure in pharynx in region of PES)

23
Q

cranial nerves responsible for salivation?

A

VII - submandibular and submaxillary glands (autonomic aspect of nerve)

IX - parotid gland (autonomic aspect of nerve)

24
Q

which cranial nerve would be most important for swallow initiation and sensory protective mechanisms of upper airway?

A

superior laryngeal nerve (CN X vagus)

25
Q

description of events of oral stage of normal swallow (10)

A
  • tongue tip occludes at alveolar ridge (holding bolus on palate)
  • edges of tongue dorsum contain bolus laterally.
  • respiration ceases, arytenoids approximate
  • retraction of tongue (mainly by extrinsic tongue muscles - digastric + mylohyoid (V), geniohyoid (XII)
  • positive pressure to bolus tail by tongue base against velum/posterior pharyngeal wall
  • velum sealed by levator veli palatini
  • palatopharyngeal folds pulled medially to allow bolus passage
  • larynx pulled up and forward
  • epiglottis descends over airway
  • bolus deflects through valleculae at tongue case, away from airway
26
Q

which muscles responsible for hyoid movement?

2

A

geniohyoid - most responsible for anterior displacement of hyoid (CN XII)

mylohyoid - most responsible for superior movement of hyoid (CN V)

(Pearson, 2011)

27
Q

when does pharyngeal stage of swallow begin?

A

when bolus is at level of valleculae. ends when PES closes.

28
Q

role of CN IX in PES opening?

A

parasympathetic signals from CN IX to brainstem relax PES muscles, to allow for hyolaryngeal movements to open them

29
Q

other name for PES/UES (muscle)

A

cricopharyngeal muscle (part of lower pharyngeal constrictor)

30
Q

innervation inside the mouth?

A

V - mucosa of cheeks, nasopharynx, soft palate, hard palate, buccal floor + gen sensory for anterior 2/3rd of tongue

VII - taste for anterior 2/3rds of tongue

IX - taste and gen sensory for posterior 1/3rd of tongue + gen sensory for oropharyngeal mucosa (tongue base, palatine tonsils - swallow initiation)

X - mucosa of pharynx, epiglottis, larynx, oesophagus

31
Q

height of UES compared to C?

A

C5-C6

32
Q

dysphagia symptoms reported by Pt
(11)

H = hidden/subtle symptomes (5)

A
  • difficulty chewing (decreased mastication efficiency - slowed down chewing) H
  • drooling (lip/tongue weakness)
  • nasal regurgitation
  • difficulty initiating swallow (dry mouth, lip/tongue weakness)
  • blockage (food doesn’t pass through)
  • frequent cough/choke (laryngeal penetration)

  • lack of swallow initiation
  • cough
  • throat clear
  • residue
  • delayed cough
  • delayed swallow initiation w/o cough (potential silent aspiration)
  • sign hidden by Pt

A
  • drooling
    (drooling saliva/bolus ; weakness in labial closure ; infrequent saliva swallows)
  • xerostomy
    (dry lips/tongue/palate)
  • difficulty chewing and/or changing diet to softer foods
    (drooling food ; slow chewing even for soft foods ; teeth decay ; misadjusted dentures ; weakness of tongue/jaw/lips ; lack of coordination of tongue/jaw/lips)
35
Q

pharyngeal phase symptoms (5) and related signs

A
  • effort during swallow/difficulty initiating swallow
    (delayed laryngeal elevation ; penetration/aspiration of bolus before swallow initiation on VFSS)
  • blockage/globus (sensation of ball)
    (residue on VFSS - sometimes oesophageal)
  • cough/choking
    (penetration/aspiration on VFSS)
  • wet cough
    (aspiration of saliva during VFSS)
  • regurgitation in oral cavity/pharynx
    (bolus not swallowed)
36
Q

causes of oesophageal dysphagia
(4 categories | 4 + 2 + 2 + 2)
+2

A

structural disorders, motility disorders, LES abnormalities, PES abnormalities

structural

  • esophageal stenosis (narrowing of lumen - can be peptic from GERD)
  • esophageal rings/webs (Schatzki’s rings)
  • tumors
  • esophageal diverticulum (bulge in weak spot on esophagus)

motility

  • nutcracker oesophagus (increased esophageal pressure - spasms)
  • diffuse esophageal spasm

LES abnormalities
- achalasia (mega-oesophagus)
(non relaxing of LES preventing passage to stomach)
- Barrett’s esophagus
(stomach cells replacing esophageal mucosa)

UES abnormalities
- Zenker's diverticulum
(posterior pharyngeal wall at Killian's dehiscence)
- cricopharyngeal bar 
(UES muscle not distending)
  • esophagitis
  • GERD / LPR
37
Q

if bad breath constant… sign of?

A

residue somewhere, for example zenker’s diverticulum.

38
Q

difference between bulbar and spinal ALS presentation?

A

Bulbar (25%) –
speech and swallow first. AAC early. Other motor later. Rapid deterioration.

Spinal (75%) –
motor limbs first. Dysarthria later. AAC later. Slow progression. (Can have total paralysis, but ability for speech/swallow)

39
Q

potential quality of life impacts of dyphagia

5

A
  • reduced enjoyment of eating/drinking from fear of doing so safely (anxiety) or increased effort
  • embarrassment may change the places in which a person is willing to eat and
    limit social activities
  • slow and fatigue in eating may impact effectiveness of eating
  • diet changes/restrictions may decrease satisfaction of eating
  • time and expense of special diets
40
Q

4 general quality of life impacts of dysphagia

A
  • fear of choking (anxiety)
  • discomfort/pain while eating
  • social insecurity
  • less enjoyment eating
