Prognostic CT Findings of Diplopia after Surgical Repair of Pure Orbital Blowout Fracture

Summary Orbital blowout fracture (BOF), a subtype of orbital fracture, refers to a fracture involving only the orbital inferior and/or medial wall, with an intact orbital rim. The fracture typically occurs after blunt trauma to the orbit. Sequelae of BOF include enophthalmos, diplopia from extraocul...

Description
Summary:Summary Orbital blowout fracture (BOF), a subtype of orbital fracture, refers to a fracture involving only the orbital inferior and/or medial wall, with an intact orbital rim. The fracture typically occurs after blunt trauma to the orbit. Sequelae of BOF include enophthalmos, diplopia from extraocular muscle dysfunction, infraorbital nerve anesthesia, disfiguring facial contours, and tearing from obstruction of the nasolacrimal duct. The goal with orbital wall reconstruction is to improve visual function and orbital appearance. However, even after proper surgical management, ocular motility disturbance and diplopia persists. Many prognostic factors have been implicated. Several studies have analyzed computed tomography (CT) findings associated with diplopia after surgical management. However, these studies evaluated the relationship between only one or two CT findings and postoperative diplopia, their populations were relatively small. Therefore, the aim of this study was to evaluate CT findings and determine possible prognostic factors leading to new or persistent diplopia after surgical repair of pure BOF.
