Question 20

overbite vs overjet

Answer 20

overbite is vertical (whole lower teeth is covered)
overjet is horizontal (there’s a wide gap only)

-furlow palatoplasty -pharyngeal flap -pharyngeal wall augmentation -sphincter pharyngoplasty

Question 27

furlow palatoplasty

Answer 27

- double opposing z plasty - lengthens the velar tissue so it can make contact with the posterior pharyngeal wall

pharyngeal wall augmentation

Answer 29

-bulge in the pharyngeal wall

physiological, function! muscle too weak etc

Question 36

Velopharyngeal mislearning

Answer 36

how theyre using is wrong
