Factors affecting satisfaction of patients after orthognathic surgery at a University Hospital.

OBJECTIVES: To analyze factors that influence patient's satisfaction with orthognathic treatment and evaluate patient's perception of changes in physical and psychosocial aspects.

METHODS: In a retrospective clinical study conducted at Jordan University Hospital, Amman, Jordan between December 2006 and December 2007, we examined 38 patients who had orthognathic surgery after an average follow-up of 20 months. Examination included evaluation of nerve function and temporomandibular function with Helkimo index. Patients filled out a questionnaire on treatment satisfaction, and perception of physical and psychosocial changes after treatment.

RESULTS: Patients were generally satisfied with the result, 82% agreed they would undergo treatment again. They were divided into very satisfied n=25 and less satisfied n=13 groups according to satisfaction score, with statistically significant differences found between them concerning diagnosis, and follow-up period, with all vertical maxillary excess patients very satisfied and 75% of asymmetrical deformities patients less satisfied, and less satisfaction by patients more than one year postoperatively p=0.006. Patients perceived improvement in oral function, general health, appearance and interpersonal skills. Lower rates of joint and muscular pain, and increased mobility of lower jaw correlated with better patients' perception of health and appearance.

CONCLUSIONS: Although patients' report high satisfaction levels, several factors such as the temporomandibular joint function could affect patients' psychosocial adjustment after treatment. Sufficient information for patients on the treatment course is required to improve satisfaction. Controlling these factors could improve patients' quality of life.
