Quality of Life After Orthognathic Surgery in Swedish Patients: A Register‐Based Cohort

Abstract

ABSTRACT Objective This study aimed to evaluate the effect of orthognathic surgery on quality of life among Swedish patients. Materials and Methods Patients subjected to orthognathic surgery due to dentofacial deformity (DFD) and registered in the National Register of Orthognathic Surgery (NROK) in Sweden between 2017 and 2020 were eligible for inclusion in this study. The Swedish‐validated Orthognathic Quality of Life Questionnaire (S‐OQLQ) was used to evaluate patient quality of life before and after surgery. The S‐OQLQ measured each patient's subjective experience regarding social aspects. Results Eighty‐four participants were included in this cohort study, including 45 men (mean age 24.7 years), 48 women (mean age 23.4 years), and eight patients who stated no gender. Women generally graded several aspects of the S‐OQLQ higher than men, including facial aesthetics p = 0.029), oral function (p < 0.001), and awareness of facial deformity (p = 0.0054). For all domains of the questionnaire (social, facial aesthetics, function, and awareness), a significant improvement was seen 6–24 months after surgery (p < 0.001). Women rated improvement of function and awareness of facial deformity higher than men (p < 0.001 and p = 0.039, respectively). Conclusion Quality of life aspects of orthognathic surgery have a strong impact on the treatment outcome. Although functional impairment is often considered a major indication for surgery, the social and aesthetic influence of DFD is highly rated by patients, whereas pain is not an issue before or after treatment.
