The Normal

Swallowing

(brief review)

Normal sequence of actions

Bolus control : glossopalatal seal

Begin of oral transition : tongue tip elevation to alveolar ridge

Tongue propulsion : food bolus move toward tongue base

Nasopharyngeal seal : velum elevation

Pharynx constricts & Tongue base move backwards

Laryngeal elevation

Epiglottis inverts

Larynx closes

Upper Esophageal Spincter open

Less than one second !

Overview of Lecture

• Normal Swallowing (brief

review)

• Instrumentation for VFSS

• Indications & Contraindications

• VFSS versus FESS & Clinical

Assessment

• Principles & Protocol

• Normal VFSS

• Pathological VFSS & reporting

Indications

• Find safe eating condition

• Identify aspiration risk

Contraindications

• Medically unstable

• Cannot position

• Poor cooperation

Instrumentation for

VFSS

• Same as Fluoroscopic

Examinaitons

• Additional Items

• Video Recorder

• Bare minimum 10 fps

• VHS & DVD(25-29fps)

• Freeze-Frame playback

• Timer (milliseconds)

Principles & Protocol

• Instrument check

• Patient instruction & consent

• Baseline anatomy review

• Lateral

• 3 ml liquid x2

• 5 ml liquid

• Cup drink

• 5 ml nectar

• 5 ml pureed

• Cookie

• Addition repeated swallowing as needed

• Special maneuvers as appropriate

Normal Video

Fluoroscope study

• No penetration

• No aspiration

• Fast and complete laryngeal

movement

• No retention

What to look for

Abnormal Video

Fluoroscope study

• penetration

• Aspiration

• Nasal regurgitation

• Delayed triggering or decreased

laryngeal excursion

• Decreased or ineffective cough

when aspirate

• retention

Common positive findings

in patients with

neurogenic dysphagia

• Delayed swallowing reflex

triggering 88%

• Dysfunction CP 75%

• Decreased tongue movement

74%

• Drooling related problems 60%

• Abnormal (hypo/hyper) gag

reflex 42/10% Posiegel M. Nervenarzt 2002

A 63 year-old male, DM,HT,DLP

- Lt MCA infarction 10 years ago, presented with loss of

consciousness and fully recovery

- Rt MCA infarction 8 months ago, presented with loss of

consciousness and mild weakness of Lt side

Now clinical was improved, but still has swallowing problem

Clinical assessment at first time(Jan 2011) showed drooling,

impaired lip and tongue movement and cannot trigger his

larynx and cannot clear his secretion. NG tube was inserted.

He also developed aspiration pneumonia 3 times and wt

loss.

Now showed normal lip and tongue movement, mildly apraxia,

normal laryngeal triggering, 2 FB-excurtion, can clear secretion

usually.

Currently he can eat banana via oral tract.

: Can he progress to more “advanced” feeding?
