Case Report of Late Post-Traumatic Orbital Wall Reconstruction with Individual 3D Printed Titanium Implant

Abstract

Aim. Purpose of these case report is to highlight the precision and accuracy obtained with patientspecific implants for orbital reconstruction designed on the basis of 3d analysis of orbital computed tomographic scan (CT) using virtual planning, computerised designing, 3d printed stereolithographic models and 3d printed titanium orbita implants to correct late post traumatic orbital deformities which causes enophthalmos, diplopia and facial deformity. Material and methods. These 2 cases report describes a patients who came to our clinic for correction of enophthalmos, persistent diplopia in upward gaze and facial deformities, more than twelve months post trauma. Three dimensional (3D) virtual treatment planning was carried out by using the 3D CT data. The unaffected orbit of the contralateral side was superimposed on the deformed orbit to highlight the defect and a customized implant was designed in the desired size and shape on 3d planning program and they were printed with 3d printer for precise anatomic orbital reconstruction. Results. There was a marked improvement in the diplopia, in upward gaze, enophthalmos and facial deformities post surgery when the individual orbital implants printed with 3d technology was used. Conclusion. The concept of 3D virtual treatment planning, 3D stereolithographic models, individual printed with 3d printer titanium mesh implants, greatly improves the correction of extremely difficult late post- traumatic orbital deformities.
