It may lead to recurrent sinus infections and difficulty with chewing or speaking. \u003c/p\u003e\u003cp\u003eCSF leak occurs in 0.2%. The risk of meningitis with a persistent CSF leak is 19%. Thus recognizing an injury to the skull base quickly is imperative, as the risk of meningitis decreases after repair of the skull base defect\u003c/p\u003e\u003cp\u003eOrbital penetration occurs in about 0.3%. This may result in injury to the medial rectus muscle leading to strabismus and diplopia.\u003c/p\u003e\u003cp\u003eAnterior ethmoidal artery injury has an incidence of 0.3%. This may cause the anterior ethmoidal artery to retract into the orbital cavity, orbital hematoma and severe, rapid proptosis.\u003c/p\u003e","id":3058,"imageUrl":null,"imageAttribution":null,"imageAttributionCaseInfo":null,"firstQuestionPath":"/questions/3059","nextQuestionPath":"/articles/functional-endoscopic-sinus-surgery-fess/questions/3057","relatedArticles":[],"alsoUsedIn":[{"id":2161,"kind":"Course","title":"Radiopaedia 2024 - Virtual Conference - page 2161","link":"https://radiopaedia.org/courses/radiopaedia-2024-virtual-conference/pages/2161"},{"id":2161,"kind":"Course","title":"2024 Virtual Conference Private Use - page 2161","link":"https://radiopaedia.org/courses/2024-virtual-conference-private-use/pages/2161"},{"id":2501,"kind":"Course","title":"2024 Virtual Conference Private Use - page 2501","link":"https://radiopaedia.org/courses/2024-virtual-conference-private-use/pages/2501"},{"id":2501,"kind":"Course","title":"Radiopaedia 2024 - Virtual Conference - page 2501","link":"https://radiopaedia.org/courses/radiopaedia-2024-virtual-conference/pages/2501"},{"id":2014,"kind":"Course","title":"2024 Virtual Conference Private Use - page 2014","link":"https://radiopaedia.org/courses/2024-virtual-conference-private-use/pages/2014"},{"id":406,"kind":"LiveSchedule","title":"406","link":"https://radiopaedia.org/admin/live_schedules/406"},{"id":374,"kind":"LiveSchedule","title":"374","link":"https://radiopaedia.org/admin/live_schedules/374"}],"stem":"\u003cp\u003eWhich \u003cstrong\u003eIS NOT\u003c/strong\u003e a major complication of functional endoscopic sinus surgery (FESS)? \u003c/p\u003e","menuLinks":[{"text":"Report problem with question","url":"https://docs.google.com/forms/d/e/1FAIpQLSfO3soWYhOjJ7yErSysyCe5V4A1CqW7WK3rDA7MtAkecMGqNw/viewform?entry.1624461248\u0026entry.553583435=https://radiopaedia.org/questions/3058"}],"attemptsPercentages":[{"alternativeId":"14852","percentage":84},{"alternativeId":"14850","percentage":3},{"alternativeId":"14851","percentage":8},{"alternativeId":"14849","percentage":5}],"promptToLogin":false,"questionManager":false,"articleId":"functional-endoscopic-sinus-surgery-fess"}
