Abstract

As the use computed tomographic (CT) scanning spread, the diagnosis of blowout fractures of the medial orbital wall increased. Now, the diagnosis of blowout fracture in the medial wall are not uncommon. Conventionally, the surgery of blowout fractures in medial orbital wall was performed by the various approach with external incision. The conventional method had seveal possible disadvantages, including an external scar, incomplete reduction, increased mobidity rate and general anesthesia. Recently, endoscopic reconstruction of the medial orbital wall has provided good functional and cosmetic results. We performed endoscopic transnasal reduction surgery without external incision in 12 cases of medial blowout fracture under local anesthesia. The fractured bony fragments were removed after the intranasal ethmoidectomy and the entrapped medial rectus was released. And then a sheet of silicone late or uncinate process were placed on the fracture site. For the maintain of the position of fractured wall, Merocel packing or urinary ballon catheter were used in orbital fracture site for 1-3 weeks. There were no specific complications related to this procedure. Result of the surgery in all cases were satisfactory. In this article, we discussed the surgical procedure, the benifit of the transnasal endoscopic approach, the indications for surgery, and possible comlications.
