Project Summary: Early identification of surgical indication is critical to optimizing outcomes in orbital floor fracture management. Delay of repair in this cohort risks persistent diplopia, persistent facial deformity, and infraorbital nerve injury. While muscle entrapment and acute globe malposition are widely accepted as absolute indications for repair, it has remained a challenge to identify those patients at risk for developing delayed enophthalmos and requiring subsequent surgery. The long term objective of this project is thus to validate a novel comprehensive quantitative clinically applicable prediction tool that guides orbital floor fracture management by stratifying risk for enophthalmos and establishing a threshold value for surgical intervention. The Orbital Index is a scoring system based on CT data that incorporates information on fracture size, fracture location, and the presence of inferior rectus muscle rounding. Each of the three components are scored from 0-2 and the aggregate Index score can thus range from 0-6. Firstly, we aim to demonstrate reproducibility and inter-observer scoring fidelity of the Orbital Index as well as its utility to aid clinical understanding and communication through use of the oribtal index by providers of differing levels of training and by surveying providers pre-and post- intervention. Secondly, we aim to correlate scores with development of enophthalmos with clinical measurements on untreated patients to identify a threshold score for surgical intervention.
Impact Statement: By validating the Orbital Index the proposed project will enable clinically applicable comprehensive stratification of risk of delayed enopthalmos following orbital floor fracture that can be easily understood and communicated. This will allow for early and accurate identification of patients that require surgery, decreasing unnecessary operations as well as delays in care, and therefore improving patient outcomes.
Edward H. Davidson received his medical education at the University of Cambridge and Imperial College London. He spearheads the New York University Institute of Reconstructive Plastic Surgery Laboratories’ division of bone biology research with interests including craniofacial surgery, bone tissue engineering, and the role of lacunocanalicular flow in distraction osteogenesis.
