Depression is a relatively common finding following any surgical procedure, and it has also been reported after orthognathic surgery. It is most evident immediately after surgery and usually gradually declines after that. During this time, additional support is needed from the family and the medical personnel. (Cunningham et al. 1995). Infection, use of sedatives, low-calorie diet associated with an increased corticotropin release factor concentration and insufficient preoperative information about the immediate consequences of the operation have been presented as predisposing factors (Stewart & Sexton 1987).
A cornerstone for successful outcome is a thorough evaluation of the patient`s expectations and careful preoperative information of the surgical process. Functional improvement from the treatment should be emphasized in consultations rather than the need to make esthetic improvements as the only reason for treatment. A good functional outcome may help the patient to accept possible adverse consequences. If the patient mostly focuses on esthetics, the chances of dissatisfaction are greater
