The following values was measured: angle of cusp line between the second and third molar, impact state and depth, distance from Rickett's Xi to distal cusp of third mandibular molar along the occlusal plane, anterior border of ramus to the third mandibular molar, distance from projection of distal contact point of maxillary third molar to intersection of pterygoid vertical on occlusal plane.The change between pre-and post-treatment was calculated and analyzed with SPSS10.0 software package.α angle, Xi-LTM, R-LTM, R-LTM were tested with independent-sample t test, impact state and depth was tested with Chi-square test. Influence of age on the values was also evaluated.

It is concluded:①The method does not traumatize the periosteum of the hard palate,thus alleviating postoperative maxillary deformity;②The buccal musculomucosal flap is generally long enough to reach across the incisive foramen and maintain good blood circulation;③The method benefits reconstruction of the levator sling and facilitates velopharyngeal closure.

该方法有以下优点：①手术不剥离硬腭区粘骨膜，对上颌骨的损伤很小，减轻了上颌骨的发育障碍；②采用两块带蒂颊粘膜肌瓣重建了腭帆提肌功能，促使异位的提肌悬吊再形成；③血运良好的颊粘膜肌瓣插入于软硬腭交界处，能使软腭充分后退，实现腭咽闭合，而且可有效地防止瘘孔的发生。
