Abstract
Background: Orbital floor fractures 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 to restore both the function and aesthetic aspect. Reconstruction of orbital floor can be performed using various types of materials, either autologous as cartilage grafts or alloplastic as titanium mesh.
Aim of the Study: the aim of this retrospective study is to compare the results of using autologous cartilage grafts with those of synthetic titanium mesh in posttraumatic orbital floor defects reconstruction & finding the most suitable implant for different sizes of defect.
Patients and Methods: 40 patients were selected from the database of Ain shams University Hospitals with orbital floor fractures that were surgically treated at the Plastic & Reconstructive Surgery Department over past 5 years. Cases were retrospectively reviewed by preoperative clinical findings, management, surgical approaches, and sequelae. The study evaluated timing, surgical outcomes and complications of materials used for orbital reconstruction & their effect on the choice of the appropriate method used for reconstruction.
Results: In total, there were (40) cases of orbital fractures surgically treated with average age of (29.2) years. Pure blow-out fractures represent 30% of cases while fractures of inferior orbital rim associated with orbital fractures were 70%. Cartilage graft was used in 16 cases for floor reconstruction while 24 cases were managed by titanium mesh. In the follow-up, 2 patients still complain of enophthalmos, while 6 patients still complain of diplopia.
Conclusion: Reconstruction of orbital floor fractures using cartilage grafts represents a safe and reliable method of reconstruction with less complication in small sized fractures measuring less than 50% of orbital volume, while titanium mesh is the best for fractures measuring more than 50% of orbital volume
