Impact of Preoperative Anxiety on Heart and Blood Pressure Changes During Surgery and on Pain, Swelling, and Jaw Movement After Bimaxillary Orthognathic Surgery

What this Trial Is About

Researchers are investigating how preoperative anxiety affects patients undergoing bimaxillary orthognathic surgery, a corrective jaw surgery for dentofacial deformities. The study aims to understand if anxiety before surgery influences changes in heart rate and blood pressure during the operation, as well as pain, facial swelling, and limited mouth opening after surgery. This observational study is conducted at Istanbul Medipol University Hospital and focuses on patients classified as ASA I or II. Participants are evaluated for anxiety using the State-Trait Anxiety Inventory before surgery and grouped into low or high anxiety categories based on their scores. During surgery, vital signs such as systolic and diastolic blood pressure, mean arterial pressure, heart rate, and oxygen saturation are closely monitored. After surgery, follow-up assessments take place at several time points from 1 hour to 1 month, measuring facial swelling with 3D scanning, pain levels using a visual scale, and mouth opening to assess trismus. Throughout the study, patients complete anxiety questionnaires and attend multiple postoperative visits for detailed evaluations. Researchers analyze the collected data to find connections between anxiety levels and physiological changes during and after surgery. The main outcome is the measurement of facial swelling after surgery, with additional focus on pain, mouth opening, and intraoperative vital signs. The study helps improve understanding of how anxiety may affect recovery and care in orthognathic surgery.
