Lateral view	Consistency of food
Oral phase	Amount of bolus	Possible swallowing disorders
Delayed oral onset of swallow		Apraxia of swallow; reduced oral sensation
Searching tongue movements		Apraxia of swallow
Tongues moves forward to start to swallow		Tongue thrust
Residue in anterior sulcus		Reduced labial tension; reduced lingual control
Residue in lateral sulcus		Reduced buccal tension
Residue on floor of mouth sulcus		Reduced tongue shaping or coordination
Residue in midtongue depression		Tongue scarring
Residue on tongue		Reduced tongue movement and strength
Disturbed lingual contraction		Disorganized A-P tongue
Incomplete tongue-palate contact		Reduced tongue elevation
Residue on hard palate		Reduced tongue elevation and strength
Reduced A-P tongue movement		Reduced A-P lingual coordination
Uncontrolled bolus/premature swallow		Reduced tongue control; reduced linguavelar seal
Aspiration (%) before swallow		Reduced tongue control
