RESUMEN
We carried out an investigation on 92 patients having benefited from an orthognathic surgery, in order to demonstrate the effects of the dento-facial deformations on the patients' everyday life and the psychological impact of the multidisciplinary treatment. Questionnaires were drawn up and sent to the residence of the patients: one preoperative, transmitted 15 days before the intervention and one postoperative, addressed 6 months afterwards. Our results revealed that all the patients of our study were satisfied and that this treatment eliminated the complex of 90% of the patients. We could highlight that the more surprising part of the treatment for the patients is the postoperative facial deformation generated by the important postoperative oedema. We concluded that the information of the patient and the communication patient-expert have a preponderant role in the therapeutic caring. .
