Background: To evaluate the results of the reconstruction of orbital floor defects by using autogenous bone graft or titanium mesh implant. Patients and method: The study was conducted on the 43 patients including 32 males and 11 females, aged from 16 to 56, who suffered from !arge orbital floor defects in the midface traumatic fractures. The treatment procedures contained fracments reduction, bone fixation and autogenous bone graft or titanium mesh implant in reconstruction of the fractured orbital floor.

Results: At 6 months postoperatively, the authors got 31 patients (72.1 percent) with good result; 12 patients (27.9 percent) were fair in functions. In Anatomical aspect: 36 patients (83.7 percent) were good; meanwhile, 6 patients (14 percent) with fair result and 1 patient (2.3 percent) got poor result. Aesthetic result: 37 patients (86 percent) were with good result; 3 patients (7 percent) with fair result and 3 patients (7 percent) with poor result. As for the long-time follow-up: In function: The good result rose to 41 patients (95.3 percent); 2 patients (4.7 percent) remained fair. The same outcome in Anatomy: 36 patients (83.7 percent) were with good result; 6 patients (14 percent) with fair result and 1 patient (2.3 percent) with poor result. Good result reduced a little bit in asthetic with 33 patients (76.7 percent); 7 patients (16.3 percent) were with fair result and 3 patients (7 percent) with poor result. Conclusion: The results of the recontruction of orbital floor defects by using autogenous bone graft or titanium mesh implant are good.
