Postoperative Changes in Isolated Medial Orbital Wall Fractures Based on Computed Tomography

Area of Science:

• Ophthalmology
• Plastic Surgery
• Medical Imaging

Background:

• Accurate reduction of blow-out fractures remains a challenge with conventional surgical techniques.
• Complete bone reduction is often limited, even with established methods like open reduction and mesh insertion.

Purpose of the Study:

• To analyze postoperative outcomes using computed tomography (CT) scans after conventional open reduction of isolated medial wall orbital fractures.
• To evaluate changes in orbital volume and distance following surgery and assess bone remodeling over time.

Main Methods:

• Review of 37 patients with isolated medial wall fractures undergoing conventional open reduction with transcaruncular approach and absorbable mesh.
• Preoperative, immediate postoperative, and 6-month postoperative CT scans were analyzed.
• Orbital volume and distance measurements were compared, with statistical evaluation of differences.

Main Results:

• Significant differences were observed in orbital volume (P < 0.05) and distance (P < 0.01) between immediate and 6-month postoperative CT scans.
• The study suggests that decreased measurements at 6 months may be attributed to scar contracture and fibrosis.
• Bone remodeling processes following incomplete reduction were analyzed.

Conclusions:

• Conventional open reduction for orbital wall fractures may lead to incomplete reduction and subsequent changes due to scar contracture.
• The bone remodeling process after incomplete reduction requires further investigation.
• Additional research is necessary to fully understand the changes occurring during bone remodeling in these cases.
