title: Maxillary bone grafts for the repair of traumatic orbital floor defects.
abstract: OBJECTIVE
  To present maxillary bone (MB) grafts as a viable option for repair of traumatic orbital floor (TOF) defects by comparing their use to titanium mesh (TM) looking at TOF defect size, operative time, and complication rate.
  
  
  METHODS
  The senior author's surgical technique is described. Patients undergoing TOF repair using MB versus TM were assessed retrospectively, focusing on TOF defect size, operative time, and follow-up results.
  
  
  RESULTS
  One hundred ninety-six patients with 212 TOF defects presented to a single surgeon between 2004 and 2008. One hundred sixty-five patients (178 TOF defects) were repaired with MB and 31 patients (34 TOF defects) with TM. The MB and TM groups were similar with respect to age, gender, time to repair, and other associated facial fractures. TOF defect size was similar between the two groups (MB: mean 1.7 cm2, range 0.32-2.82 cm2; TM: mean 1.9 cm2, range 0.5-2.83 cm2). Follow-up was slightly longer in the TM group; however, many patients were lost to follow-up. There were no donor-site complications in the MB group and no significant difference in postoperative complications in the MB group versus the TM group (11% vs 24%). The operative time in patients with TOF defects was slightly longer in the MB group versus the TM group (35 min vs 27 minutes, p = .02).
  
  
  CONCLUSIONS
  This series is the largest published series to date. MB was used successfully to repair TOF defects, with no increased risk of complications and only a slightly longer operative time compared to TM. MB offers an autogenous bone graft source that is technically easy to harvest and in the same surgical field, obviating many of the complications associated with alloplastic materials and traditional bone graft choices. MB grafts should be considered a viable option when choosing material to repair TOF defects.
