Comparative analysis of the nasal effects of two alar cinch suture techniques in LeFort I osteotomy. A retrospective longitudinal study

Orthognathic surgery produces significant changes in nasal morphology. However, only the interalar width showed differences between sling techniques, with a greater increase in the group using the sling that passes through the anterior nasal spine. These findings indicate that the choice of sling affects control of the nasal base, while projection and the nasolabial angle depend on maxillary movement.
