Summary
Orthognathic surgery minimally impacts body posture, with no significant spinal changes observed in skeletal class III and asymmetry cases. Skeletal class II patients showed minor postural shifts without orthopedic consequences.
Area of Science:
- Orthodontics and Maxillofacial Surgery
- Biomechanical Analysis
- Scoliosis and Postural Studies
Background:
- Orthognathic surgery corrects jaw discrepancies, potentially influencing spinal alignment.
- Assessing postoperative postural changes is crucial for patient outcomes.
- Video rasterstereography offers a non-invasive method for back surface analysis.
Purpose of the Study:
- To evaluate spinal posture using video rasterstereography before and after orthognathic surgery.
- To determine the effect of different skeletal classes (III, II) and mandibular asymmetry on body posture post-surgery.
Main Methods:
- Video rasterstereography, a moire topography-based technique, was employed for back surface measurement and shape analysis.
- Twenty-nine patients (17 skeletal class III, 7 skeletal class II, 5 with asymmetry) were assessed preoperatively and one year postoperatively.
Main Results:
- Orthognathic surgery in skeletal class III and asymmetry groups showed no significant changes in body posture.
- Skeletal class II patients exhibited minor postural alterations, deemed without significant orthopedic consequences.
Conclusions:
- Orthognathic surgery demonstrates minimal to no adverse effects on overall body posture.
- Postural stability is largely maintained following corrective jaw surgery across various skeletal discrepancies.
