Clinical outcomes of 3-dimensional printed custom porous polyethylene orbital implant for reconstruction.

Abstract

PurposeTo report the clinical outcomes with three-dimensional (3D)-printed custom orbital implants, designed using contralateral orbit mirroring techniques.MethodsCase series of 3D-printed custom orbital implants used for complex orbital reconstructions at University of Michigan Kellogg Eye Center is presented in this study. Data from 2020 to 2023 was collected.ResultsIn this case series of 8 patients, the surgical indications include diplopia, enophthalmos, hypoglobus either post-trauma or tumor removal. One patient had bilateral defects; others had unilateral defects. The mean follow-up time was 27.88 ± 9.66 months (Range: 7-38 months). Postoperative improvement was seen for enophthalmos in 7 of 8 cases, hypoglobus in 3 of 5 cases, and diplopia in 3 of 4 cases, and the average exophthalmometry asymmetry improved from 3.1 mm to 0.5 mm.Conclusions3D-printed orbital implants demonstrated effectiveness and safety in this diverse series of orbital reconstruction cases, yielding significant clinical improvements. Our findings support the use of these implants in a variety of complex orbital reconstructions.
