Abnormal Vs Normal Swallowing Flashcards
Normal swallow
Oral propulsion of bolus into pharynx
Airway closure
UES opening
Tongue base and pharyngeal wall contact
Propel bolus through pharynx into esophagus
Stages of swallowing
Oral prepatory
Oral
Pharyngeal
Esophageal
Actions to analyze during a swallow
Oral phase Tongue palatal seal Nasopharyngeal seal Compression/propulsion of bolus Hyoid/laryngeal elevation Epiglottic tilt Cricopharyngeal opening Esophageal peristalsis
Normal oral phase
Lips engulf bolus
Bolus held at rest in front of mouth
Mastication
Tongue transfers bolus into pharynx
Abnormal oral phase
Drooling Poor bolus formation Prolonged oral stage Difficulty initiating a swallow Loss of bolus Oral residue
Normal tongue palate seal
Soft palate rests against posterior tongue blade w out kinking
Abnormal tongue palatal seal
Kinking of soft palate
Loss of bolus over base of tongue
Premature leaking
Normal soft palate-pharyngeal seal
Soft palate elevates to appose passavants cushion
Abnormal soft palate-pharyngeal seal
Sluggish elevation of palate
Nasopharyngeal regurgitation
Normal bolus compression/propulsion
Retraction of BOT
Contraction of constrictors
Abnormal bolus compression/propulsion
Diminished constriction
Failure of lateral pharyngeal walls to come midline
Normal hyoid elevation, laryngeal closure and epiglottic tilt
Larynx moves up and forward
Epiglottis moves horizontally
Epiglottis inverts
Abnormal hyoid elevation, laryngeal closure and epiglottic tilt
Absent hyoid to mandible
Incomplete epiglottic tilt
Vallecular retention
VF open during swallowing
Normal cricopharyngeal opening
Closed between swallows
Relaxes and opens completely to allow bolus flow
Abnormal cricopharyngeal opening
Opens late/incomplete
Closes early
Trapping of bolus
