Reconstruction of orbital wall defects: Recommendations based on a mathematical model

Modeling enophthalmos in reconstructed orbital floor defect using a mathematical engineering model.293Highlights► (Early) onset of enophthalmos is related to change in orbital volume. ► We have developed a model in which materials for orbital floor reconstruction can be evaluated. ► Mechanical properties, deformation, orbital floor defect size and orbital volume are critical. ► The model is helpful in selecting reconstruction mate rials accounting for critical parameters. ► With the model, clinicians can preoperatively judge whether a selected material is suitable.
