Comparison between Custom 3D-Printed Titanium Meshes and Stock Titanium Meshes in Orbital Floor Repair: A Retrospective Analysis
View through CrossRef
Purpose:
To compare the clinical outcomes of patient-specific customized 3D-printed titanium meshes (PSIs) and stock titanium meshes in orbital floor reconstruction.
Methods:
This retrospective case series included 48 patients undergoing orbital floor repair between June 2024 and March 2025. Patients were divided into Group 1 (
n
= 22) receiving custom 3D-printed titanium meshes and Group 2 (
n
= 26) receiving stock titanium meshes. Operative time, orbital volume restoration (via 3D volumetric analysis), resolution of enophthalmos, diplopia, and infraorbital paresthesia were assessed. Volumetric measurements were performed using semi-automatic segmentation based on CT scans.
Results:
The 3D-printed meshes achieved a better restoration of orbital volume, with a mean reduction in volumetric discrepancy of 89% (SD ± 28%), compared to 51% (SD ± 35%) in the standard mesh group (
P
= 0.036). No statistically significant differences were observed in operative time or in the resolution of paresthesia. However, a statistically significant difference between the two groups was found in the resolution of both enophthalmos and diplopia (
P
= 0.025 and
P
= 0.028).
Conclusion:
Custom 3D-printed titanium meshes showed improved anatomical accuracy and volumetric outcomes compared to stock meshes. Further prospective studies with long-term follow-up are necessary to confirm these findings and assess cost-effectiveness.
