Evaluation of bony changes observed in mandibular osteotomy lines and mandibular condyles following bilateral sagittal ramus osteotomy by fractal analysis

Evaluation of trabecular changes following advancement genioplasty combined with or without bilateral sagittal split osteotomy by fractal analysis: a retrospective cohort study

“…No difference was reported in patients undergoing genioplasty in this study. Moreover, the results of the present study are also consistent with the literature by Çolak et al, that bone healing in horizontal osteotomies at 6 months after orthognathic surgery was similar [ 29 ]. In contrast, it was concluded in the present study that genioplasty only and genioplasty combined with BSSO and mandibular advancement did not differ in radiographs taken at least 6 months later.…”

“…The measurements were obtained from the panoramic radiographs, a square of 50 × 50 pixels: two regions of interest (ROIs) were selected bilaterally on the mandibular angulus area, three ROIs were selected within the genial segment of the mandible, and one ROI was selected on the osteotomy healing area on both radiographs (Fig. 2 ) [ 29 ]. In the present study, the reason for evaluating the angulus regions (ROI 4 and 5) that will not be affected by occlusal forces and surgical procedures is that the regions that are not included in the osteotomy area were also examined for individual control in the literature [ 4 , 29 , 30 ].…”

In order to ensure the reproducibility of the measurements, except for the osteotomy line measurement, the other measurements were made to be at the same level of the teeth and just above the cortical bone border and at the same size as the first measurements.…”
