Delayed Repair of Lateral Orbital Wall and Orbital Floor Fracture

Abstract

Timing of surgical management of facial fractures may differ from the current standard when an associated severe ophthalmologic injury exists; this may necessitate a delay in repair to protect the patient's vision. We set out to demonstrate that good functional and aesthetic outcomes can be achieved in cases where zygoma bone fracture repair had to be delayed for more than 21 days after injury with a specific surgical plan.Using the electronic database from Montreal General Hospital, a level I trauma center, a retrospective review of all facial fractures occurring from 1994 to 2009 was performed. Our review returned a total of 22,727 trauma patients admitted to Montreal General Hospital. Of these, 2672 sustained 1 or more facial fractures. Among the facial trauma patients, 945 patients' injuries included a zygoma fracture, 324 (35.3%) of which were managed operatively. Seven cases had their surgery delayed for more than 21 days after injury, 2 of which were managed using simple osteotomies and plate fixations, without the need for bone grafts. Both patients demonstrated a satisfactory outcome with improvement relative to their preoperative status. We provide a detailed description of our most recent case of a 73-year-old woman in whom the surgical repair of the lateral orbital rim and orbital floor was delayed for 10 weeks to allow healing of her associated traumatic retinal detachment.For patients with associated ocular injuries who cannot undergo orbital fracture repair within 21 days of the trauma, delayed surgery may still result in an acceptable aesthetic result.
