The definition, evaluation and assurance of quality of health care are becoming increasingly important with health care moving into purchaser/provider mode, This questionnaire based study investigated patient satisfaction and changes in their quality of life following joint orthodontic/surgical treatment for the correction of facial deformity. Questionnaires were distributed to 83 pre-operative and a separate group of 100 postoperative patients with data analysis involving comparison of pre- and postoperative mood states and opinions about various aspects of appearance and personality, The results indicated that the majority of respondents were happy with the outcome of treatment, There was significant improvement in appearance, as well as in self-confidence, overall mood states and the ability to mix socially. The majority of respondents felt that the technical aspects of the operation had been well explained but almost a quarter felt that the effects following surgery were badly explained, Pre-operative counselling, therefore, needs to be improved.
