Breathing pattern, orthognathic surgery and head posture in dentofacial deformity

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