A retrospective review to assess the performance and clinical predictive value of a novel software program (Maxillo) designed to perform complex volumetric analysis with application in the field of orbital trauma.

The concept of open reduction and internal fixation of large and complex traumatic orbital deformities is well established. It is known that successful orbital reconstruction hinges upon restoration of native orbital volume in order to establish pre-morbid function and avoid long-term complications. To date, a facile, reliable, and reproducible method to measure orbital volume has not been rendered, despite numerous approaches. The objective of this study is to assess the performance and clinical predictive value of a novel software program designed to perform complex volumetric analysis with application in the field of orbital trauma.

Inclusion Criteria:

• Chart reviews of patients at UCDMC with orbital trauma and having operative repair of the orbital fractures with post-reduction imaging included.

Exclusion Criteria:

• Absences of post-operative imaging

Patients with complex maxillofacial and orbital trauma that underwent operative repair of orbital fractures. Computer tomography scans from a cohort of patients with normal CT data sets will also be collected to assess "normative" orbital volumes.
