One-piece Lefort osteotomy versus segmental procedure for maxillary skeletal deformities - A retrospective study
International Journal of Research in Pharmaceutical Sciences
Maxillary skeletal deformities can occur in all three planes and are corrected by orthognathic surgery. Osteotomies form the basis for orthognathic surgeries. One of the most commonly used osteotomy techniques for maxillary skeletal deformities is the LeFort osteotomy. The aim of this study was to compare the application of One Piece LeFort Osteotomy and Segmental Osteotomy procedures in the treatment of maxillary skeletal deformities. The institutional study involved analysis of case sheets of
... patients who underwent surgical correction of maxillary skeletal deformities in the stipulated time frame and assessment based on the parameters: Demographic data, type of cephalometric analysis, cephalometric values, type of skeletal deformity, and technique of Osteotomy. Statistical analysis was calculated by chi-square test. A p-value<0.05 was considered significant. Maxillary skeletal deformities were more prevalent among females (60%) than males (40%). Anterior maxillary segmental osteotomies were more commonly performed (60%), followed by LeFort 1 osteotomy (26.7%). The prevalence of posterior osteotomy technique was 13.3%. A statistically significant association was revealed between the type of skeletal malocclusion and technique of Osteotomy used, with a p-value of 0.008<0.05. The type of malocclusion dictates the technique of Osteotomy is used. In a skeletal Class II, segmental malocclusion procedure was more preferred for maxillary deformities.
