The clinical characteristics of orbital complications of sinusitis and paranasal cyst

Abstract

　We treated 20 patients with acute sinusitis or paranasal cysts accompanied by orbital complications between January 2007 and September 2017. This retrospective study of these patients analyzed age, sex, location of sinus lesions, visual disturbance, and the relationship between the outcome and the interval between the onset of the visual disorder and the surgical procedure. Visual outcomes were poor for patients with sinusitis when the interval between the onset of the visual disturbance and surgery was＞48 hours. On the other hand, visual disturbances resulting from paranasal cysts were potentially reversible. However, visual outcomes were poor for patients with rapid deterioration of visual acuity. Many complications due to cysts required more time to diagnose. Therefore, cysts in the posterior ethmoid sinus should be suspected when patients with visual impairment have a history of transantral sinus surgery.
