Cephalometric variables measured:

1 = SNA (angle between sella, nasion and subspinale point A);

2 = SNB (angle between sella, nasion and supramentale point B);

3 = ANB (angle between the maxilla and the mandible);

4 = PAS (the narrowest distance between the base of the tongue and the posterior pharyngeal wall);

5 = MP-H (distance from the mandibular plane to the most anterior point of the hyoid bone);

6 = Co-A (amount of the maxillary advancement);

7 = Co-Pog (amount of mandibular advancement).
