When a blowout fracture with a clinically significant orbital floor defect is repaired, autologous material is preferable for the orbital floor graft.
A clinically significant orbital floor defect will be defined as a gap remaining after reduction or elevation of orbital floor fracture fragments that requires a semirigid implant to avoid postoperative enophthalmos or orbital dystopia. Therefore, this definition excludes small defects (<5 mm in width) where Gelfilm (Pharmacia and Upjohn Inc, Kalamazoo, Mich) or fascia could be used without the need for rigid or semirigid support of the orbital contents.
