Pre-surgery anxiety and its effects on heart rate, blood pressure, pain, swelling, and mouth opening after orthognathic (jaw) surgery

Official title: The Effect of Preoperative Anxiety Levels on Intraoperative Hemodynamic Parameters and Postoperative Edema, Pain, and Trismus in Patients Undergoing Bimaxillary Orthognathic Surgery: A Prospective Observational Study

Run by Istanbul Medipol University Hospital · NCT07439679 · Data updated 2026-11-12

This will see if higher anxiety before bimaxillary orthognathic surgery leads to bigger changes in heart rate and blood pressure during the operation and to more pain, facial swelling, or limited mouth opening afterward.

Is this trial a fit for you?

Likely a good fit

Adults with dentofacial deformities scheduled for bimaxillary orthognathic surgery who are ASA I or II, able to complete the STAI questionnaire, non-pregnant, non-smokers, and without major systemic or psychiatric conditions are ideal candidates.

Probably not a fit

Patients with prior orthognathic surgery, head/neck radiation, active smoking or substance abuse, chronic systemic diseases affecting healing, psychiatric disorders, pregnancy, or inability to attend follow-up visits are excluded and unlikely to benefit from these findings.

What this trial studies

This is a prospective, single-center observational study at Istanbul Medipol University including patients undergoing bimaxillary orthognathic surgery (Le Fort I plus bilateral sagittal split osteotomy). Preoperative anxiety is measured with the State-Trait Anxiety Inventory (STAI-I and STAI-II) and patients are grouped by STAI-I score. Intraoperative hemodynamic parameters (systolic, diastolic, mean arterial pressure, heart rate, and SpO2) are recorded at predefined time points. Postoperative outcomes—three-dimensional facial edema measurements, pain via Visual Analog Scale (VAS), and maximum mouth opening—are collected at 1 hour, 1 day, 2 days, 5 days, 10 days, and 1 month after surgery.

Why it matters

Potential benefit: If a clear link is found, clinicians could identify anxious patients before surgery and offer targeted interventions to reduce intraoperative instability and improve postoperative pain, swelling, and jaw opening.

How similar studies have gone: Previous work in other surgical fields has linked higher preoperative anxiety to intraoperative hemodynamic changes and worse postoperative pain or swelling, though focused data in bimaxillary orthognathic surgery are limited.
