A Case Report on the Application of a 3D Printed Patient-specific Zygomatic Implant for a Post-traumatic Facial Deformity.

Abstract

We present the case of a 47-year-old male with a post-traumatic facial deformity after electrocution injury and a fall that occurred two years prior to consultation. The patient presented with ectropion on the left, hypoglobus, and step-off deformities on the left malar area owing to the loss of a large portion of the inferior orbital rim, orbital floor, and the zygomatic bone. House-Brackmann IV facial palsy was also present on the left hemiface since the injury. A 3D-printed biocompatible zygomatic implant was fabricated using Polyetheretherketone (PEEK). This case highlights the versatility of PEEK for facial implants and the importance of virtual surgical planning and 3-D printing in the management of post-traumatic facial defects.
