(a)

Lateral viewConsistency of food
Preparation to swallowAmount of bolusPossible swallowing disorders

Cannot hold food in mouth anteriorlyReduced lip closure
Cannot form bolusReduced tongue movement rage or coordination
Cannot hold bolus—premature bolus loss
Aspiration (%) before swallow
Reduced tongue shaping/coordination; reduced velar movements
Material falls into anterior sulcusReduced labial tension
Materials falls into lateral sulcusReduced buccal tension
Abnormal hold positionTongue thrust; reduced tongue control
Posture introduced

(b)

Lateral viewConsistency of food
Oral phaseAmount of bolusPossible swallowing disorders

Delayed oral onset of swallowApraxia of swallow; reduced oral sensation
Searching tongue movementsApraxia of swallow
Tongues moves forward to start to swallowTongue thrust
Residue in anterior sulcusReduced labial tension; reduced lingual control
Residue in lateral sulcusReduced buccal tension
Residue on floor of mouth sulcusReduced tongue shaping or coordination
Residue in midtongue depressionTongue scarring
Residue on tongueReduced tongue movement and strength
Disturbed lingual contractionDisorganized A-P tongue
Incomplete tongue-palate contactReduced tongue elevation
Residue on hard palateReduced tongue elevation and strength
Reduced A-P tongue movementReduced A-P lingual coordination
Uncontrolled bolus/premature swallowReduced tongue control; reduced linguavelar seal
