ABSTRACT
BACKGROUND:
Le Fort I maxillary movements affect nasal width, but nasal width changes with specific movement types have not been formally addressed to date.OBJECTIVES:
The purpose of this study was to analyze and compare the changes in nasal width with different maxillary movements.METHODS:
A retrospective study was performed among consecutive patients who underwent bimaxillary orthognathic surgery (n = 138) and who were grouped based on the type of maxillary movement (ie, maxillary advancement with intrusion [MAI], maxillary advancement with extrusion [MAE], and maxillary setback with intrusion [MSI]). Preoperative and 12-month postoperative nasal widths were analyzed photogrammetrically by 2 blinded evaluators.RESULTS:
Maxillary advancement with intrusion and MAE presented a significantly (P < 0.05) higher alar base widening than MSI did, with no significant (P > 0.05) differences between MAI and MAE. Maxillary advancement movements (MAI and MAE) showed significantly (P < 0.05) higher alar base widening than maxillary setback movement (MSI). However, no significant (P > 0.05) difference was observed between maxillary intrusion (MAI and MSI) and maxillary extrusion (MAE) movements.CONCLUSIONS:
This study shows that the nasal width varies distinctly depending on the type of Le Fort I maxillary surgical movement.
