Abstract:CBCT is a viable alternative to CT in the routine postoperative evaluation of orbital fracture reconstruction. However, in the patient who develops gaze restriction postoperatively, conventional CT is preferred over CBCT for its superior soft tissue resolution to exclude extraocular muscle entrapment.
“…We obtained results similar to those of Tsao et al [7] in the appreciation of the soft tissue migration. They included in the study only four patients, that were examined with CBCT after surgical treatment for orbital fractures.…”

Background and aimThis study aims at evaluating the reliability on specific multi-planar cone beam computer tomography (CBCT) reconstruction in the orbital floor fractures.MethodsCBCT examination of the mid-face fractures area involving the floor of the orbit was performed in a number of 93 trauma patients by two independent radiologists. Both radiologists assessed the axial, coronal and sagittal sections and also the oblique coronal and sagittal extracted sections evaluating the location of the orbital fractures, its size and displacement, the involvement of the infra-orbital foramen, herniation of fat or muscle within the maxillary sinus, the overall type of the fracture and the implication of lateral or medial orbital wall. We also registered the section that provided better confidence of both examiners in visualizing the fracture of the orbit floor and the presence of herniated soft tissue, on different reformatted sectioning.ResultsThe presence of pure fracture of the orbital floor was detected in 11% of patients. The association of the orbital fractures with the zygomatic fractures was identified in the majority of the patients. In 86% of patients the displacement of the floor of the orbit was visualized, and in almost 30% of cases more than 50% of the orbital floor was involved in the fracture. Regarding the confidence between examiners, they were more confident using the oblique sagittal CBCT reformatted images for fracture detection and bone displacement evaluation, as for the soft tissue herniation the oblique coronal sections provided the highest level of confidence.ConclusionMid-face trauma involves the orbital floor in the majority of situations. CBCT allows to obtain oblique images extracted from the three dimensional (3D) data that provide high confidence level in assessing pure orbital floor fractures.

“…When indicated, surgical management involves reconstruction of the orbital wall fracture defect with either autogenous bone or alloplastic material. By re-establishing the continuity and contour of the orbital walls, this restores support for the globe and intraorbital soft tissue and treats/prevents sequelae like enophthalmos, dystopia, and diplopia [1][2][3][4][5][6][7][8][9][10][11].…”
Introduction: Our primary aims are to report on the demographics of orbital trauma in Adelaide, South Australia. Our secondary aims are to demonstrate the long-term (>12 months) clinical outcomes of orbital trauma patients. Materials and Methods: Forty patients agreed to participate in the study, including 20 surgical patients and 20 non-operative patients. Patients were assessed in the areas of demographics, sensory, visual and cosmetic outcomes. Results: In the surgical patient group, 13/20 (65%) patients suffered trauma from physical assault and 16/20 (80%) were males. In the non-surgical patient group, 17/20 (85%) suffered trauma from physical assault and 16/20 (80%) were males. In the surgical patient group, sensory deficit was reported in 8/20 patients (40%), visual deficit was reported in 8/20 patients (40%), and cosmetic deficit was reported in 6/20 (30%) patients. In the non-operative patient group, sensory deficit was reported in 7/20 patients (35%), visual deficit was reported in 8/20 patients (40%) and cosmetic deficit was reported in 6/20 patients (30%). Conclusion: Our clinical study of 40 patients showed no clear clinical or statistical difference between outcomes in the two groups. Impaired visual, sensory and cosmetic deficits were reported in the minority and did not impact on quality of life.
