title: Orbital complications of paranasal sinus surgery.
abstract: Despite the low complication rate from surgery of the paranasal sinuses, orbital injury may be seen in up to 3% of all procedures. These complications include orbital edema, orbital hemorrhage, enophthalmos, extraocular muscle injury, and nasolacrimal duct obstruction. The most devastating complication is blindness, usually resulting from optic nerve compression with central retinal artery occlusion, or direct injury to the nerve itself. Early recognition of orbital injury during sinus surgery and appropriate intervention may prevent later, more serious ophthalmic complications.
