Abstract

Differential superior reposition of maxilla following LeFort I osteotomy in the correction of maxillary cant poses a greater challenge especially when associated with the pathology like fibrous dysplasia which completely obliterates the antrum. Purpose of this paper is to highlight the modification of LeFort I osteotomy and hypothesis is to assess its difficulty index in modifying the standard steps, in executing the maxillary separation at various to correct the gross facial asymmetry to achieve a favorable outcome. Multiphased management involved scrupulous clinical planning, advanced imaging by computed tomgraphy scans, stereolithographic models to debulk the lesion. The second phase included pre surgical orthodontic evaluation along with correction of severe maxillary cant adopting a modified LeFort 1 osteotomy technique and standard bilateral sagittal split osteotomy, thereby simultaneously attaining functional stability and esthetic harmony.
