Timing of orthognathic surgery on the changes of oral health-related quality of life in Chinese orthognathic surgery patients

Although the association between orthognathic surgery and oral health-related quality of life (OHRQoL) has been explored, few studies have been carried out to describe the influence of surgery type on perceived OHRQoL. The aim of this study was to evaluate the difference of OHRQoL between a surgery-first approach and an orthodontics-first approach, using the 14-item Oral Health Impact Profile questionnaire (Chinese version).
