Original publication title: Repair of Orbital Floor Fractures Using Maxillary Bone Grafts.
Plain-English summary
This study looked at using pieces of bone from the upper jaw (maxillary bone grafts) to fix fractures in the floor of the eye socket caused by trauma. The researchers compared the results of surgeries using these bone grafts to those using titanium mesh in 389 patients over 15 years. They found that while the bone grafts took a little longer to use during surgery, they had fewer complications compared to the titanium mesh. Overall, the study suggests that maxillary bone grafts are a good option for repairing these types of fractures.
Abstract
<h4>Background</h4>This study aimed to present maxillary bone grafts as a favorable option for the reconstruction of traumatic orbital floor (TOF) defects.<h4>Methods</h4>The senior author's preferred surgical technique using a transconjunctival incision is described. Patients undergoing TOF repair using maxillary bone grafts versus titanium mesh were then assessed retrospectively, with a focus on the size of the TOF defect, operative time, and complications.<h4>Results</h4>A total of 389 patients presented with 426 TOF defects to a single surgeon between 2006 and 2021. Maxillary bone grafts were used to repair the orbital floor fracture in 304 patients (332 fractures), whereas the remaining 85 patients (94 fractures) were repaired using titanium mesh. There were no significant differences in age or sex. Orbital defect size was slightly higher in the titanium mesh group (bone graft group: mean 1.58 cm<sup>2</sup>, range 0.29-2.91 cm<sup>2</sup>; titanium mesh group: mean 1.74 cm<sup>2</sup>, range 0.38-2.98 cm<sup>2</sup>). There were fewer complications observed when using the autogenous bone graft substrate (10%) versus titanium mesh (18%). No major donor-site complications were documented in the bone graft group. Operative time was marginally higher in the bone graft group than in the titanium mesh group (35.9 versus 29.2 min).<h4>Conclusions</h4>This study serves as the largest clinical series to date examining indications, surgical technique, safety, and efficacy of maxillary bone grafts in TOF repairs. Maxillary bone grafts represent a viable option to be considered in the armamentarium of the craniofacial surgeon for the treatment of TOFs.
