Traditionally, orbital floor fractures are repaired with standard transcutaneous or transconjunctival approaches. Complications such as external scarring, eyelid edema, ectropion, entropion, and granuloma formation have been associated with these open lid techniques. The endoscope has been used to assist in orbital floor exploration, to reduce entrapped orbital tissue, and to identify the posterior shelf for implant placement. However, an open lid incision is inevitable when implant placement is necessary. We present our experiences in repairing orbital floor fractures using transantral endoscopy without open lid incision. A 0°, 4-mm endoscope was placed through a 2 x 1.5-cm² maxillary antrostomy to dissect the sinus roof. The endoscope was used to assist in the reduction of the floor fractures and prolapsed orbital tissue into the orbital cavity, if present. The orbital floor defect was reconstructed with titanium mesh or Medpor through the antrostomy under endoscopic control. . . . [Full Text of this Article]
