Abstract

Abstract Introduction: Dentofacial deformity (DFD) and the breathing mode can change the head posture. However, head posture changes after orthognathic surgery are controversial, and no studies were found on the relationship between the head posture and breathing mode in adults with DFD. Objective: To identify the main head posture changes in young adults affected by DFD, to verify if orthognathic surgery modifies the breathing mode and head posture, and if the breathing mode is associated with the head posture. Methods: Twenty-five young adults were assessed and divided in dentofacial deformity group (DFD; n = 15; x̅ = 28 years) and control group with dentofacial harmony (CG; n = 10; balanced by gender and age with the study group). Breathing mode was evaluated according to the orofacial myofunctional evaluation protocol, and biophotogrammetry was used in the head posture analyses. For the DFD group, the evaluations were performed pre and post the orthognathic surgery (pre- and post-DFD). Results: For the DFD group, the breathing mode modified after orthognathic surgery (p = 0.003), but with difference from GC (p = 0.027). No changes were found in head posture after orthognathic surgery, but significant difference was seen between post-DFD and GC for head inclination (p = 0.017). No relationship was observed between breathing mode and head posture (p > 0.05). Conclusion: After orthognathic surgery, a spontaneous improvement of breathing was seen in the sample. It was not possible to verify changes in head posture and association with breathing mode and head posture.
