local.description.resumoObjectives: The purpose of this study was to evaluate post treatment skeletal stability of a sequence of eleven nonsyndromic patients who underwent subcranial Le Fort III and Le Fort I osteotomy. Methods: To test if the long-term stability was satisfactory, the authors compared cephalometric changes from immediately after surgery to 18 months follow-up taken from multislice computed tomography using two different software. Findings: All patients were submitted to a final advancement of upper incisor of at least 10mm. There was no statistical difference between the measures taken from the two different software and interclass correlation was at least good for each cephalometric variable. The advancement of the upper incisor, A-point, posterior nasal spine and nasion was highly stable, presenting less than 01mm of relapse after 18 months in vertical and horizontal analysis. No statistical difference was seen between short- and long-term follow-up. Infraorbital also showed a highly stable result, without significant differences after 18 months. Conclusion: Subcranial Le Fort III midface advancement combined with Le Fort I is an effective surgical technique to correct malocclusion and midface hypoplasia with excellent postsurgical stability. Both software showed similar results and proved to be an efficient clinical tool to study stability.
