module 8 Flashcards
What is velopharyngeal closure?
sphincteric activity that takes place in the nasopharynx and involves movements of soft palate and pharyngeal walls.
what happens to the soft palate in velopharyngeal closure?
elevated/retracted
VP closure- coronal
mainly the soft palate moving back
VP closure- saggital
mainly the lateral pharyngeal walls moving in
VP closure- circular
equal contribution from lateral pharyngeal walls and soft palate
VP closure- Circular with Passavant’s Ridge:
contribution from posterior wall makes for complete circular pressure.
Main muscles of velopharyngeal closure
(PULS) Palatopharyngeus Uvulus Levator veli palatinis Superior pharyngeal constrictor
Levator veli palatini
elevates and retracts soft palate.
Uvulus
bulk and changes palate shape.
Palatopharyngeus
narrows vp port; brings soft palate down during swallowing
Superior pharyngeal constrictor
affects inward movement of lateral pharyngeal walls
Stigmata for a submucous cleft palate
- Bifid uvula
- Midline lucency (soft palate, hard palate, or both)
- Notch in bony palate
- Levator insertion onto bony palate
The role of the adenoid pad in velopharyngeal closure in child vs adult
- Minimal adenoid in adult
- Adenoid present in children
- VP closure for adults; Veloadenoidal closure for children until puberty
Where is the adenoid pads?
• The adenoid pads (or tonsils) are above the level of the soft palate.
T/F the adenoid pad is visible intra-orally
