Impact of orthognathic surgery on quality of life in patients with different dentofacial deformities1558Pain scoreThe pain score was measured on a scale from 0-10 from day 1 (T1) to at least 1 year (T10) after the operation. Because of the low response rate to the questionnaire, it was analyzed from day 1 to week 4 (Figure 2). The Friedman test was used to analyze the data, showing a significant decrease in the mean pain score from day 6 compared to day 1 (n = 46). Pain scores significantly positively correlated with OHIP scores for every time point except for 6 months (T9) (Table 8). No correlation was found between pain and age, gender, blood loss, time of surgery, indication for surgery, or type of surgery (P > .05).
