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

• Course Objective
• “Enable Participants to Confidently Perform and
Interprets VFSS”
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?
