Background: Orbital floor fractures always represent a challenge for reconstruction. Various techniques for treatment had evolved over the past years, each with their strengths and weaknesses. The main aim of surgical repair is to relocate herniated orbital tissue and fat back into the orbit restoring both the function and aesthetic aspect. Reconstruction of orbital floor can be performed using various types of materials, either autologous as rib grafts or cartilage grafts or alloplastic as titanium mesh. Aim of the Study: The aim of this study is to compare the results of using autologous cartilage grafts with those of split rib graft in small posttraumatic orbital floor defects reconstruction. Patients and Methods: 30 patients with orbital floor defects due to maxillofacial trauma. They were divided into 2 groups according to the technique of reconstruction: Group 1: 15 patients who had reconstruction by onlay split rib grafts Group 2: 15 patients who had reconstruction by conchal cartilage grafts, using either unilateral or sutured bilateral conchal cartilage grafts in large defects. Both methods were analyzed clinically and radiologically and were compared as regards, their advantages and disadvantages Postoperative assessment using CT scan were used. Results: With the conchal cartilage grafts, the results were more favorable with statistically significant decrease in complications. Conclusion: Reconstruction of orbital floor fractures using conchal cartilage grafts represents a safe and reliable method of reconstruction with less complications.

Comparative Study between Conchal Cartilage Grafts and Split Rib Grafts in the Reconstruction of Orbital Floor Fractures
