Maxillofacial trauma, a common injury in urban population following road traffic accident or act of interpersonal violence of which orbital floor fractures is common. It impairs the integrity of the extraocular muscles and may be accompanied by enophthalmos, orbital deformity and diplopia. Orbital reconstruction is essential to improve anatomical and visual deformity. Repair of orbital floor is done by autologous bone graft or synthetic implants. Compare outcome of orbital floor reconstruction in blow out orbital fracture using autogenous bone graft from iliac crest, outer table of mandible, alloplastic implant- silastic block and titanium mesh. 30 patients having orbital fractures were considered in study population. All the patients were treated by ORIF and repair of floor by subcilliary incision. Out of 30 patients, repair of orbital floor was done by autologous bone graft from iliac crest in 7 patients (Group A), bone graft from outer table of mandible in 5 patients (Group B), implant using silastic block in 8 patients (Group C) and titanium mesh in 10 patients (Group D). Factors analyzed were age, sex, cause of fracture and treatment outcome in terms of correction of pre operative diplopia and enophthalmos, rate of development of post operative infection, wound dehiscence and implant exposure. All patents were reviewed at 4 weeks and 12 weeks following operation. 71.42% of patients in Group A had early correction of diplopia and enophthalmos. This was 100% in rest of the groups. All patients had complete correction when assessed at 12 weeks post operatively. Post operative complication rate was 20% and 12.5% in Group B and C respectively. There were no complications in the rest of the groups within the follow up period. No statistically significant difference as to the chance of occurrence of complication could be found amongst the groups. Autologous bone graft has no immunological reaction but donor site morbidity. Silastic block may case immunological reaction, infection, poor drainage of orbital floor. But titanium mesh for orbital floor repair has excellent outcome and superior to other modality of treatment.
