This study was conducted to clarify the influence of palatoplasty on maxillary growth.
Noncleft children (NC group) and patients treated with the push-back (PB group) method, the buccal musculomucosal flap (BF group) method, and two-stage palatoplasty combined with a Hötz plate (TS group) were compared in regard to maxillofacial growth by the use of a lateral cephalogram obtained before orthodontic treatment.
The results were as follows :
In comparison with the NC group, the PB group is short in height and depth of maxilla, and the points of the mandible are back and upward corresponding to the change of the maxilla.
In comparison with the NC group, the TS group at point U1 and the point of mandible is downward at every point except L1.
In comparison with the NC group, the BF group position of U1 and Mo is backward.
In comparison with the BF group, the PB group's significant difference is in the anteroposterior direction on the maxilla.
In comparison with the TS group, the BF group showed no significant difference. The entire balance on the maxillofacial shape of both the BF group and the TS group was similar.
From these results, the different palatoplasty brought on the different results in maxillofacial growth, and palatoplasty is considered a possible way to improve surgical methods.
