title: Endoscopic transnasal approach for treatment of the medial orbital blowout fracture using nasal septum graft.
abstract: We present the experience of the Ear, Nose, and Throat Department of Santa Casa de Misericórdia de Curitiba and Hospital Universitário Cajuru PUC-PR in the transnasal endoscopic approach to medial orbital blowout fractures using nasal septum grafts. Seventeen patients have undergone endoscopic repair since June 2005, and septum grafts were used to maintain the orbital contents in position. All 17 patients were treated with this method. Two patients had diplopia on immediate postoperative evaluation. This symptom was corrected with orthoptic exercises in one patient, and the other had a little residual diplopia. Postoperative computed tomography scans showed anatomic reduction in 14 of 17 cases. There were no complications in these surgeries. The transnasal endoscopic approach is a reasonable method for the treatment of medial orbital blowout fractures. Use of septum graft is another surgical alternative for this technique.
