A rare complication of endoscopic sinus surgery: necrotizing fasciitis of the eyelid.

Necrotizing fasciitis is a soft tissue infection characterized by necrosis of fascia and subcutaneous tissue. It frequently involves the groin, abdomen and lower extremities, but rarely involves the head and neck region. An unusual occurrence of periorbital necrotizing fasciitis after a routine endoscopic sinus surgery in a 57-year-old woman with a history of type II diabetes mellitus is presented. Although the disease is very rare, all the physicians should be aware of the manifestations of this disorder and its treatment. Early recognition and prompt intervention plays an important role in minimizing the morbidity and mortality rates.
