What this Trial Is About
Orthognathic surgery leads to changes in the three-dimensional position of the jaws, which may result in alterations in head and neck posture as well as overall body posture. These postural changes are also expected to influence plantar pressure distribution. This study aims to evaluate the direction and magnitude of these changes by assessing posture and plantar pressure measurements before and after orthognathic surgery. Postural analysis and plantar pressure measurements will be performed preoperatively and at the 6-month postoperative follow-up in patients undergoing orthognathic surgery. In order to allow a reliable comparison, a control group consisting of non-operated individuals will also be included. The range of natural changes observed in the control group will be determined, and the outcomes will be compared between the surgical and control groups. By comparing preoperative and postoperative measurements, this study aims to evaluate the effects of orthognathic surgery on body posture and plantar pressure distribution. The findings are expected to contribute to the identification of parameters that should be considered in postoperative evaluation and rehabilitation. Furthermore, the results will provide valuable information regarding the postural and plantar pressure changes observed in patients following orthognathic surgery.
