Psychological evaluation of patients scheduled for orthognathic surgery.
MetadataShow full item record
Using a questionnaire, 41 patients scheduled for orthognathic surgery were evaluated pre- and postoperatively to determine some of their psychological characteristics and treatment outcome from the patient's standpoint. Among other conclusions, the results showed that some patients may not fully understand the details of their deformity, despite a full explanation by the orthodontist and surgeon. Expectations regarding treatment outcome may be unrealistic even in patients with valid self-motivation for surgery. Social adjustment usually improves after treatment. Functional changes were noticed by over 80% of the patients and esthetic changes in over 90%.
