Aim: The purpose of this study is to compare the success rate and possible complications when using calvarial bone and titanium mesh as a reconstruction material for orbital floor; assessing their reliability in that field.

Methods: 17 patients with impure orbital blowout fractures were classified into 2 groups; in group A; the orbital floor was reconstructed using autogenous calvarial bone graft, while in group B; titanium mesh was the material used in orbital floor reconstruction. The degree of success, persistence of symptoms and possible postoperative complications in term of diplopia, enophthalmos, ocular motility were recorded and compared in both groups.

Results: 14 of the 17 patients were males and 3 females. Road traffic accident was the most common cause of trauma. Both calvarial bone graft and titanium mesh succeeded in orbit floor reconstruction effectively in terms of function and esthetics with minor amount of complications; one patient in the calvarial bone graft group experienced wound dehiscence, another patient of the titanium mesh group acquired enophthalmos post operatively, also there was a patient from each group who experienced ectropion. All patients with other symptoms as diplopia, ocular motility disorders and numbness were improved.

Conclusion: Calvarial bone and titanium mesh are a very good orbital reconstruction material with good functional and esthetic outcomes and low rate of complications.
