Assessing the Viability of Polycaprolactone Mesh in Bilateral Orbital Floor Reconstruction: Insights From Le Fort II
1Department of Plastic and Reconstructive Surgery, Ajou University School of Medicine, Suwon, Korea.
Objective:
This study aims to evaluate the effectiveness of pure polycaprolactone (PCL) mesh in reconstructing complex bilateral orbital floor fractures associated with Le Fort II fractures. PCL mesh is traditionally viewed as less suitable for severe fractures due to its perceived weakness. This study challenges that perception by demonstrating the utility of PCL mesh in high-severity cases.
Materials And Methods:
Two patients with Le Fort II fractures and bilateral orbital floor fractures underwent orbital reconstruction using a 3D-printed PCL mesh. The mesh was molded and inserted through subciliary or transconjunctival incisions. Orbital volumes were analyzed preoperatively and postoperatively using CT scans and a 3D Analysis program.
Results:
Both cases demonstrated significant correction of orbital volume differences postoperatively, leading to improved symmetry and successful reconstruction. For case 1, the preoperative orbital volume difference of 3.2 cc was reduced to 1.1 cc postoperatively. For case 2, the preoperative orbital volume difference of 1.18 cc was reduced to 0.4 cc postoperatively. The PCL mesh provided adequate structural support and facilitated effective tissue integration. Despite the radiolucency of the PCL mesh on CT scans, volumetric analysis confirmed stable and balanced orbital volumes.
Conclusions:
Pure PCL mesh is a viable alternative for orbital floor reconstruction in severe craniofacial fractures, offering a balance of structural support and biocompatibility. To validate these findings, further research with larger samples and long-term follow-up is recommended.
