In the _______ pattern, lateral pharyngeal walls close in and velum may not move much. Rare. (5%)

The _______ pattern is true ________ _______ where velum lifts up and _______ pharybgeal walls close in. Rare. (4%)

In ________ w/_______ _______, the velum moves, _______ pharyngeal wall moves and _______ pharyngeal wall moves. Creates a bunched up _______ appearance. Very rare.

A

The velopharyngeal port closes in a reflexive, specific pattern, everytime that cannot be changed. Coronalpattern (A-P closure) is the most common of all velar movement (80-90%) and the most problematic for children w/cleft palate?

In the sagittal pattern, lateral pharyngeal walls close in and velum may not move much. Rare. (5%)

The circular pattern is true sphincteric closure where velum lifts up and lateral pharybgeal walls close in. Rare. (4%)

In circular w/passavant’s ridge, the velum moves, lateral pharyngeal wall moves and posterior pharyngeal wall moves. Creates a bunched up muscle appearance. Very rare.
