Reconstruction of the Orbit
Orbital defects require careful consideration due to the need to protect globe position and visual function. The orbit’s unique geometry requires working within a confined space. When indicated, orbital rim fractures or segmental defects can be reconstructed using low-profile, titanium mini-plates. Multiple implant options are available to support the globe when defects involve the orbital floor or medial wall. These materials should be able to contour to match the concavity of the orbit, thereby avoiding changes in orbital volume. For complex defects, virtual surgical planning strategies, including intra-operative navigation or the use of anatomic models for pre-operative plate bending or cutting guides for secondary osteotomies, can improve precision and reduce operative time. This chapter will describe operative indications and practical management options for orbital defects. This review contains 7 figures, 1 video, 2 tables, and 38 references.
