This study aims to investigate the relationship between preoperative anxiety and intraoperative hemodynamic changes, as well as postoperative pain and facial edema, in patients undergoing orthognathic surgery.
Orthognathic surgery is a corrective jaw surgery performed to treat dentofacial deformities. Although the procedure improves functional and aesthetic outcomes, patients may experience significant anxiety before surgery. Elevated anxiety levels may influence physiological responses during the operation and may affect postoperative recovery.
In this study, preoperative anxiety levels will be evaluated using validated assessment scales prior to surgery. During the intraoperative period, hemodynamic parameters such as heart rate and blood pressure will be recorded. After surgery, postoperative pain and facial edema will be assessed using standardized clinical evaluation methods.
The objective of this research is to determine whether higher levels of preoperative anxiety are associated with changes in intraoperative hemodynamic stability and increased postoperative discomfort. The findings may contribute to improved perioperative management strategies and enhanced patient care in orthognathic surgery.
