Abstract

A numerous materials have been used for reestablishing continuity of the orbital floor in orbital floor fracture. Traditionally autogeneous bone has been utilized for reconstructing orbital floor defect but autogeneous bone has been criticized for unpredictable resorption, donor site morbidity and difficulty in shaping & fixation. Alloplastic materials have gained some popularity because of their availability and ease of use but they have disadvantages like infection, extrusion and implant displacement. There is an alternative to bone grafts and inorganic implants for reconstruction of orbital floor defect ; auricular conchal cartilage. The auricular conchal cartilage, however, has convolution so the authors have made the conchal cartilage flat and malleable by crusher. Crushed autogeneous conchal cartilage has proved to be a material that is easy to obtain and shape and can reliably support the orbit without evidence of resorption. Crushed autogeneous conchal cartilage offers an attractive alternative to inorganic implants and bone grafts in properly selected patient for orbital floor reconstruction.
