Endoscopic intranasal reduction of the orbit in isolated blowout fractures

Abstract

We have experienced 40 cases of endoscopic intranasal reduction of the orbit in blowout fractures. CT scan confirmed isolated orbital floor fracture in 11 patients, isolated medial wall fracture in 17 patients, and combined fractures of the orbital floor and the medial wall in 12 patients. Twenty five patients had diplopia, 20 patients had limitation of eye movement, and 14 patients developed enophthalmos. Thirty three of the 40 patients recovered completely without any residual eye symptoms or complications.
