Stability after Mandibular Setback with Bilateral Saggital Split Osteotomy

Shihiji Srivastava, Mukul Padhye

Introduction bilateral sagittal split osteotomy (bsso) is the most commonly performed jaw surgery. Bsso of mandible is a surgical method used to correct the sagittal, transverse and vertical position of the lower jaw. Aim The aim of this study was to assess the stability of bsso for setback of mandible and its relationship to intra-operative positioning of the proximal segment during fixation. Methodology of the 25 bsso patients whose records were originally identified, 5 subjects were dropped because of loss of follow up. Lateral cephalograms were taken at time points t1, t2, t3, and t4. These cephalograms were traced and superimposed using burr stones analysis for the assessment of amount of setback needed. Results our study shows that its a general tendency for the recovery in the position of the posterior border of the ascending ramus in the postsurgical phase to be greater in cases in which its posterior displacement during surgery was greater. Conclusion mandibular retropositioning for correction of mandibular prognathism results in significant soft and hard tissue changes in the lower face. If the position of the proximal segment of the mandible is changed during the fixation procedure during mandibular setback surgery, the proximal segment has a tendency to move back toward its presurgical position in the period following surgery.
