Oral Prep Stage
CN V, VII, X, XII
VOLUNTARY
Oral Stage
CN XII
VOLUNTARY
Pharyngeal Stage
CN IX, XI, X
VOLUNTARY & INVOLUNTARY
Esophageal Stage
CN X
INVOLUNTARY
Lower Brainstem Stroke
difficulty, delayed, or absent pharyngeal swallow, reduced laryngeal elevation, reduced UES opening, info regarding taste, cough, & gag reflex so can GROSSLY aspirate (can have absent cough reflex)
Upper Brainstem Stroke
delayed swallow, not absent
Total Laryngectomy
backflow of material into pharynx, poor pharyngeal pressure, nasal regurgitation, fistula can cause retrograde aspiration, reduced UES or PES opening, reduced pharyngeal stripping wave, complaints of food “sticking”
oral cancer
everything reduced, slowed or delayed in oral and pharyngeal stages
laryngeal cancer
reduced laryngeal elevation, glottal & laryngeal closure, UES/PES opening, & pharyngeal wall contraction
UES
upper esophageal sphincter-located at lower end of pharynx. guards entrance to esophagus. pressure driven, larynx elevates and UES opens to let bolus into esophagus. prevents reflux of esophageal contents into pharynx.
floor of mouth
elevates hyoid and larynx
when to introduce infant to food
4-6 months. based on when reflexive responses have diminished along with motor development (sitting up, holding cup, etc)
signs of reflux in infants
gagging, choking, apnea, halitosis, burping, frequent swallowing, emesis (vomiting)
Pierre Robin Sequence
u-shaped cleft, glossotopsis (tongue held back), micrognathia (small jaw), retrognathia (retraction of jaw-obstructs airway, respiratory distress with feeding because tongue constantly moving back, *grunting, coughing, sputtering,
eosinophilic esophagitis
allergic inflammation of the esophagus. causes food impaction, poor appetite, and reflux
