## 5 Conclusions  
OFA and SFA showed QoL scores gradually improving in each domain until 6 months after surgery. The pattern of improvement in the SFA group was facial esthetics (E) at 1 month, followed by awareness of facial deformities (A) and social aspects of deformity (S) at 3 months, followed by oral function (F) at 6 months, respectively, after surgery. The pattern of improvement in the OFA group was facial esthetics (E) and social aspects of deformity (S) at 1 month, followed by oral function (F) at 3 months, followed by awareness of facial deformities (A) at 6 months, respectively, after surgery. The most concerning domain for Thai patients in our center's OQLQ was the facial esthetic domain. OQLQ is a useful questionnaire for follow up orthognathic surgery outcome.
