Early-stage postoperative depression and anxiety following orthognathic surgery: a cross-sectional study

Abstract Background The objective of this study was to observe the incidence and potential risk factors of postoperative depression and anxiety in patients during the early period after undergoing orthognathic surgery. Methods From March 7 to September 7, 2023, patients ≥ 18 years of age who were scheduled for elective orthognathic surgery under general anesthesia in Peking University School and Hospital of Stomatology were included in this study. We prospectively evaluated their degrees of pre- and postoperative depression and anxiety using the Patient Health Questionnaire-9 and the State Trait Anxiety Inventory. Associations between the perioperative factors and occurrences of postoperative anxiety and depression were evaluated using a multivariate logistic regression model. Results A total of 371 patients were included in the analysis. Within five days after surgery, we observed the occurrence of depression in 32% (116) of the patients and anxiety in 72.8% (270) of them. Their preoperative depression score on the Pain Catastrophizing Scale and intraoperative urine output were significantly associated with a higher risk of postoperative depression. The presence of preoperative anxiety, postoperative moderate-to-severe pain, postoperative nausea and vomiting and postoperative insomnia were significantly associated with a higher risk of postoperative anxiety. Furthermore, a monthly income ≥ ¥10000 was found to be significantly associated with a lower risk of postoperative anxiety. Conclusions Postoperative depression and anxiety are common among patients who undergo orthognathic surgery. Moreover, preoperative psychological status and incidence of postoperative adverse events were associated with an increased risk of depression and anxiety after surgery. The results of the present study suggest that careful psychological assessment and appropriate management are necessary to improve patients’ recovery following orthognathic surgery.
