Endoscopic sinus surgery for the treatment of frontoethmoidal mucocele complicated with orbital abscess: a case...

Mucoceles may develop after several decades following sinus surgery. They can progressively expand over many years and destroy the surrounding bones, which may result in severe complications such as orbital infection or intracranial lesions. A 68-year-old woman was hospitalized with the chief complaints of exacerbated right orbital swelling and progressive visual loss for one week in May 1995. Under the impression of the right frontoethmoidal mucocele complicated with orbital abscess, she underwent endoscopic sinus surgery for marsupialization and wide drainage of the mucocele. The symptoms subsided one week post-operatively without ophthalmological sequelae. There has been no recurrence one-year post-operatively. Endoscopic sinus surgery is an effective treatment for frontoethmoidal mucocele.
