A Case Report of Blepharotosis as a Complication of Endoscopic Sinus Surgery / 대한이비인후과학회지

ABSTRACT

Endoscopic sinus surgery (ESS) is a common procedure performed in patients with chronic sinusitis. Although most of them result in excellent outcomes, some complications due to injury of nearby structures, such as the orbit or brain, may have serious consequences. Ophthalmic complications, occurring in less than 1% of all ESS cases, include orbital hematoma, diplopia, injury to the nasolacrimal duct, and in severe cases, even blindness. Here, we present a rare case in which a 49-year old female developed unilateral blepharoptosis after undergoing revision ESS.
