Reconstruction orbitaire post-traumatique par grilles en titane préformées versus non préformées

Abstract

We compared, clinically and radiologically, the accuracy and reliability of two types of titanium mesh plates used for orbital reconstruction. The first were non-preshaped mesh plates (NPMP) and the second were three-dimensionally preformed mesh plates (PMP). Two groups were created, each including 15 patients treated with NPMP and the second formed by 15 patients treated with PMP. The volume of each orbit was computed from coronal CT-scans using the OsiriX medical imaging software (version 3.3.2, www.osirix-viewer.com). Measurements were done for both, healthy and reconstructed sides. The other studied parameters were: sex, age, fracture distribution, and complications (diplopia and enophthalmia). The orbital volume difference between the reconstructed and the healthy contralateral side was not statistically significant in either group (NPMP: p=0.991 PMP: p=0.200). The mean orbital volume of reconstructed orbits was not statistically significant in either group (NPMP: 21.76 cm(3) and PMP: 20.28 cm(3), p=0.441). There is no difference in orbital volume reconstructions measured by the OsiriX software between non-preshaped and three-dimensionally preformed titanium mesh plates.
