Detailed Description

This prospective observational study aims to investigate changes in depressive symptoms and subjective esthetic perception in patients with different types of malocclusion undergoing bimaxillary orthognathic surgery. Participants will be evaluated before surgery and during the postoperative follow-up using validated assessment questionnaires.

The study will analyze anonymized data obtained from routine clinical records and patient-reported questionnaires. Variables to be collected include age, sex, occupation, educational level, social media use, and patients' subjective perceptions of esthetics and depressive symptoms. The findings will contribute to a better understanding of the psychological and esthetic outcomes associated with orthognathic surgery and may help optimize patient evaluation and treatment planning.
