AbstractDentofacial deformities have an adverse impact on functional as well as psychological wellbeing. Being highly visible, they may lead to a host of psychological problems particularly in youths and young adults as concerns about bodily identity and integrity are likely to be most prominent. Body image and self-esteem have been noted to play an important role in adjusting to disfigurement. Those who opted for corrective orthognatic surgery with realistic expectations were found to have a higher level of satisfaction with the outcome of the surgery. In contrast, undue and unrealistically positive aspirations towards the surgery are implicated in increased post-operative psychological difficulties. This study aimed to systematically document the variability of psychological adjustment and study the predictors of well-being in individuals with dentofacial deformity after orthognathic surgery. Seventy patients pending to go through orthognathic surgery were recruited from a university based dental hospital. Assessments of the patients’ overall psychological condition and adjustment towards their dentofacial deformity were conducted with standardized questionnaires and compared with similar assessment conducted with control subjects. The patients’ motivations for orthognathic surgery, psychological well-being, as well as expectations on the outcomes of surgery were studied through individually conducted psychological assessment interviews. Patients were re-assessed at 6 and 12 months after surgery on their level of satisfaction toward the outcome of surgery as well as to gauge possible changes in their psychological condition. There was no excess of significant psychopathology in patients with dentofacial deformity compared to the normal control group. However, as predicted, people with dentofacial deformity were more dissatisfied with their facial attractiveness. They also have more problems in interpersonal sensitivity. In the patient group, functional impairment or disability was a lesser concern compared to body image and presentation. Improvement of physical attractiveness was a strong underlying motivation for treatment. Longitudinal data on patients’ level of satisfaction with the treatment outcomes and perceived benefits associated with the improved facial esthetics will be further analyzed in the light of their underlying psychological vulnerabilities or resilience. The results are expected to cast light on factors that may affect patients’ satisfaction with the treatment. The results of the study confirmed that dissatisfaction with facial appearance prompted acceptance of surgery despite its associated discomfort and hazards. The findings of the study are expected to be useful in better informing clinical psychological interventions with aims of enhancing adjustment and forestalling psychological morbidity through early intervention with individuals coping with facial disfigurement.
