AbstractSkeletal Class III malocclusion can significantly impact psychological well-being. Although bimaxillary surgery is a well-established corrective intervention, its psychological effects are not fully understood. This study aims to investigate changes in self-esteem, sensitivity to criticism, and social appearance anxiety following surgery to inform targeted nursing interventions for psychological adaptation. This comparative study included 205 participants: 150 patients with skeletal Class III malocclusion who underwent bimaxillary surgery, and a control group of 55 individuals without malocclusion. The malocclusion group had a mean age of 21.99 ± 2.28 years (96 males, 109 females). The control group consisted of department interns with Class I occlusion, normal overjet and overbite, and typical facial appearance, with a mean age of 21.61 ± 2.40 years (26 males, 29 females). Psychological assessments, validated for reliability, measured self-esteem, sensitivity to criticism, and social appearance anxiety before and after surgery. Statistical analyses, including independent sample t tests and one-way ANOVA, were performed to compare outcomes between the groups, with a significance level set at P < .05. Preoperative assessments revealed that patients with skeletal Class III malocclusion had significantly lower self-esteem and higher sensitivity to criticism and social appearance anxiety compared to the control group (P < .05). Postoperatively, there were modest improvements in self-esteem and significant reductions in sensitivity to criticism and social appearance anxiety, though levels of social appearance anxiety remained higher than those in the control group (P < .05). No significant differences in self-esteem and sensitivity to criticism were observed between the surgical and control groups postoperatively (P > .05). Within-group comparisons showed significant improvements in all measures after surgery (P < .05). Bimaxillary surgery positively affects the psychological well-being of patients with skeletal Class III malocclusion, enhancing self-esteem and reducing sensitivity to criticism and social appearance anxiety. However, some psychological concerns persist, indicating a need for targeted nursing interventions to further support these patients' psychological well-being.Copyright © 2024 the Author(s).
