Clockwise and Counterclockwise Le Fort I Movements Influence Nasolabial Morphology Differently

摘要

Background: Le Fort I maxillary advancements affect nasal proportions. However, there are no data on the three-dimensional nasal changes that occur with differential lateral plane adjustment (clockwise and counterclockwise movements) during Le Fort I maxillary advancements. This study analyzes and compares nasolabial soft-tissue changes after Le Fort I clockwise and counterclockwise repositioning.
