A review of the literature clearly shows that dental and facial disfigurements have significant effects and can be an important social disadvantage. The motivational patterns of patients requesting orthognathic surgery are many and varied, but a desire for improvement in esthetics and alleviation of functional problems are the two most commonly cited reasons. The careful assessment of patients requesting orthognathic surgery is imperative, because the success of surgery may well depend on careful patient selection. Care must be taken with those patients suspected of exhibiting dysmorphophobic tendencies and, if there is any doubt, psychiatric referral should be undertaken. Patient satisfaction following orthognathic surgery has been reported as high overall, as has been the number of patients who have said they would re-elect to have surgery. Many of the studies found that patients had improved self-confidence and social skills after treatment.
