Some measure indices of velopharyngeal configuration were collected and analyzed.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n The average maxillary advancement distance was 4.08 \u00b1 1.58 mm. The velar length, velar angle, and nasopharyngeal depth increased, but velar thickness decreased. The motion of the soft palate had no significant change, but the motion of the posterior pharyngeal wall and the Passavant's ridge increased significantly. No significant linear correlation was found between maxillary advancement distance and velopharyngeal configuration changes.<\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n Correction of maxillary hypoplasia by Le Fort I osteotomy with maxillary advancement increases the velopharyngeal cavity depth, which may impair velopharyngeal competence. The compensatory effects of the velopharyngeal soft tissue and posterior pharyngeal wall may alleviate this impairment to a certain extent.<\/jats:p>\n
