Navigation-guided surgery in orbital trauma

Abstract

There are times in an orbital surgeon's life when experience and instincts seem inadequate and there is a need for some extra guidance and technical support. High-velocity injuries with shattered orbits are one such instance. In these cases, the entire orbit is disrupted and there are no bony landmarks to guide placement of implants and restoration of volume. Orbital walls have complex curvatures and it is extremely difficult to reestablish and symmetrize this complex three-dimensional (3D) anatomy. Inadequate reductions and poor implant placements are common causes of postoperative persistent enophthalmos. Intraoperative navigation guidance has greatly aided in accurate localization of bony landmarks, in planning complex reconstructions and verifying adequate reconstruction and symmetry, and in planning patient-specific or customized 3D-printed implants. It has brought in a revolution in the treatment of orbital trauma in current times.
