Assessing the Effect of Psychometric Properties on Patients' Postoperative Self-Esthetic Scores in Orthognathic Surgery Using the Chinese Version of the Depression Anxiety Stress Scale 21

This study aimed to evaluate the impact of psychometric properties on patients' postoperative self-esthetic scores following orthognathic surgery using the Chinese version of the Depression Anxiety Stress Scale 21 (DASS-21). The research involved patients diagnosed with dentofacial deformities who underwent orthognathic surgery. A comprehensive questionnaire was administered, covering 3 key areas: clinical characteristics, self-awareness of esthetics and expectations, and psychometric parameters assessed through the Chinese version of DASS-21. Patients completed the questionnaire both before and after surgery, and the data were analyzed using the R statistical package. The findings revealed that preoperative anxiety scores, anxiety grades, and changes in anxiety levels from presurgery to postsurgery were independent factors influencing the self-perceived outcomes postorthognathic surgery (SPOPO) score. In addition, patients with asymmetrical deformities reported lower SPOPO scores, while the discrepancy between preoperative expectations and self-cognition was positively associated with SPOPO. The study concluded that postoperative satisfaction in orthognathic surgery is influenced by multiple factors, including the type of deformity, patients' self-awareness and expectations, and their anxiety state. The Chinese version of DASS-21 emerged as a valuable tool for orthognathic surgeons in predicting patients' postoperative esthetic satisfaction.
