Psychosocial Variables Associated with Orthognathic Surgery: A Systematic Literature Review

Orthognathic surgery is a type of orthodontic treatment recommended for patients with dentofacial deformities. This issue has grown in the scientific community and, more recently, in the field of psychological science since there is an increasing number of people resorting to this type of treatment and psychologists are being hired to meet emotional needs of such patients. This paper focuses on a review of the literature from the last nine years and seeks to determine if some of the psychosocial characteristics of the patient contribute to the effectiveness of orthodontic-surgical treatment. Our research identified 14 studies and the results are presented according to the following: (a) pre-surgical phase; (b) short-term and mid-term post-surgical phases; and (c) long-term post-surgical phase. We observed that some of the patient's characteristics and a closer patient-caregiver relationship seem to contribute to the satisfaction of the treatment. However, it is the quality of preventive psychological support towards risk factors that seems to determine the success of this orthodontic treatment. Overvaluation of expectations towards psychological benefits, insecurity in the decision making, lack of knowledge about the emotional costs of the surgery, lack of social support (or family pressure) as well as psychopathological disorders justify the need of psychological support. Finally, some positive and negative patient characteristics have been pointed out in this paper, and suggestions for future investigations have been made.
