Periorbital Emphysema as a Complication of Functional Endoscopic Sinus Surgery

Abstract

Clinically significant periorbital emphysema is an unusual complication of functional endoscopic sinus surgery (FESS). In most instances, it resolves spontaneously without any serious sequelae. Rarely, it can progress rapidly and become severe enough to cause irreversible blindness. We present and discuss the management of 2 cases of periorbital emphysema after FESS.
