Ophthalmic complications of endoscopic sinus surgery.
The intimate anatomical relationship between the orbit and the paranasal sinuses places the orbit and its contents at risk of harm from primary pathologic processes of the sinuses. In the absence of ophthalmic signs or symptoms, ophthalmologists are not routinely involved in the management of patients with sinus disease. Occasionally, some patients may develop ophthalmic complaints after surgical intervention. The orbit, optic nerve, extraocular muscles, and lacrimal drainage system are susceptible to injury during endoscopic sinus surgery. The risk of injury is related to the skill of the sinus surgeon, history of previous surgery, extent and severity of disease, and anatomic variation. Furthermore, recent advances in endoscopic sinus surgery, in particular the use of powered cutting instruments, has resulted in a novel mechanism of injury to the ocular structures.
