Body postural realignment in the first 2 months after orthognathic surgery

Area of Science:

• Orthodontics and Maxillofacial Surgery
• Biomechanical Analysis
• Skeletal Malocclusion Correction

Background:

• Static posture assessment is crucial for patients undergoing orthognathic surgery.
• Understanding postural adaptations in Angle Class II and III malocclusions post-surgery is key.

Purpose of the Study:

• To evaluate static posture changes in patients with Angle Class II and III malocclusions during the initial two months after orthognathic surgery.
• To compare postoperative posture with preoperative and control group data.

Main Methods:

• Longitudinal observational study involving 35 adult patients (orthognathic surgery group and control group).
• Static posture analyzed using PostureScreen Mobile application in four views at preoperative, 1-month, and 2-month postoperative time points.
• Surgical procedures included bilateral sagittal split osteotomy and optional genioplasty.

Main Results:

• Angle Class II patients showed a tendency for left hip translation (anterior view) and significant anterior shoulder translation (right lateral view) at 1 month post-surgery.
• Significant anterior knee translation was observed in Angle Class II patients at 1 month compared to other groups.
• Angle Class III patients exhibited posterior head translation at 1 month, contrasting with the preoperative anterior translation.

Conclusions:

• Static posture undergoes significant realignment in the first two months following orthognathic surgery.
• Postural adaptations vary between Angle Class II and III malocclusions after surgical correction.
