Reconstruction of Orbital Defects

Abstract

Traumatic injuries and oncologic defects of the orbit can present several challenges to the reconstructive surgeon. Fracture care has evolved over the past 20 years, and emphasis is placed on both rigid fixation and minimizing postoperative complications related to surgical exposure. Computed tomography data can now be reformatted to create three-dimensional representations that improve our diagnosis and interpretation of common fracture patterns. In cases of tumor invasion, a multidisciplinary approach will optimize outcomes for the patient. The primary objective after enucleation is to maintain soft tissue and bony orbital volume, which will facilitate use of a prosthesis. Exenteration requires circumferential orbit resurfacing, especially in cases of concomitant craniotomy and partial maxillectomy. The ultimate priority in orbit reconstruction, regardless of etiology, is to provide aesthetic and functional reconstruction.
