Endonasal endoscopic reduction of blowout fractures of the medial orbital wall.
OBJECTIVE
This article describes the endonasal endoscopic reduction (EER) of blowout fractures (BOFs) of the medial orbital walls and reports the clinical results.


METHODS
Sixteen patients who underwent EER for a BOF of the medial orbital wall were analyzed. The surgical indications for treatment were diplopia, limitation of eye movements, and significant enophthalmos. They were followed-up for at least 3 months after the surgery. Surgical techniques, surgical results, and postoperative complications were reviewed.


RESULTS
There were no significant intraoperative or postoperative complications. Fourteen patients showed complete resolution of symptoms after the surgery. One patient, who had persistent diplopia and remaining enophthalmos, underwent medial wall reconstruction with a Medpor surgical implant (Porex Surgical Inc, College Park, GA) by a transorbital approach. Another patient, who had residual enophthalmos, had correction of enophthalmos after insertion of a Medpor implant. Both patients are now symptom-free.


CONCLUSIONS
The results indicate that EER is a safe and effective technique for the treatment of BOFs of the medial orbital wall.
