Polycaprolactone Resorbable Mesh versus Titanium Mesh for the Management of Orbital Floor Fracture: A Comparative Study.

Abstract

<h4>Background</h4>Orbital floor fractures are among the most common craniofacial injuries, often resulting from high-impact trauma such as motor vehicle accidents. Orbital floor fractures comprise 4%-16% of facial fractures and are of particular interest due to their unique anatomy and proximity to the eye. Treatment typically involves reconstruction with various materials as described in the literature.<h4>Aim</h4>The aim of the study was to evaluate the effectiveness of polycaprolactone (PCL) mesh in comparison to titanium mesh in the management of orbital floor fractures.<h4>Methods</h4>Twenty patients with clinically and radiographically confirmed orbital floor fractures were assigned to two groups: Group A (PCL mesh) and Group B (titanium mesh). Pre- and postoperative assessments included ocular motility, diplopia, dystopia, enophthalmos, infection, and implant stability. Follow-up evaluations were conducted on postoperative day 1, at 1 week, 1 month, and 3 months.<h4>Results</h4>PCL mesh demonstrated superior intraoperative handling, whereas adaptability and stability were similar between groups. Postoperatively, diplopia occurred in one patient (5%), dystopia in three patients (15%), and enophthalmos in five patients (25%), with no cases of infection, inflammatory response, implant migration, or hardware failure. All fractures achieved successful defect closure.<h4>Conclusion</h4>Both PCL and titanium meshes are effective for moderately sized orbital floor reconstructions. PCL mesh offers easier handling and is a viable alternative to titanium, though larger studies with longer follow-up are needed to confirm these findings.
