Abstract
Statement of the Problem: Approximately 25-40% of cleft patients develop maxillary hypoplasia requiring Le Fort I osteotomy. Maxillary advancement brings the soft palate forward and can lead to velopharyngeal insufficiency (VPI) and hypernasal speech. The goal of this study was to identify predictors that place cleft patients at risk of developing velopharyngeal incompetence after LeFort I maxillary advancement.
