CGs are slowly expanding, cystic lesions that are rarely observed in the frontal sinus. Frontal sinus CGs characteristically present with proptosis, diplopia, and a unilateral painless expanding mass above the orbit. Patients frequently report a history of chronic nasal obstruction or head trauma. Although the pathogenesis is unclear, it is likely multifactorial in etiology. Surgical resection via endoscopic sinus surgery has been gaining popularity because of the minimally invasive approach and lower rates of recurrence.<\/jats:p>","DOI":"10.2500\/ar.2014.5.0073","type":"journal-article","created":{"date-parts":[[2014,2,5]],"date-time":"2014-02-05T22:08:51Z","timestamp":1391638131000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":10,"title":["Frontal Sinus Cholesterol Granuloma: Case report"],"prefix":"10.1177","volume":"5","author":[{"given":"Nicholas L.","family":"Deep","sequence":"first","affiliation":[{"name":"Division of Otolaryngology\u2013Head and Neck Surgery, Department of Surgery, University of Alabama at Birmingham, Birmingham, Alabama"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohamad R.","family":"Chaaban","sequence":"additional","affiliation":[{"name":"Division of Otolaryngology\u2013Head and Neck Surgery, Department of Surgery, University of Alabama at Birmingham, Birmingham, Alabama"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ajaz L.","family":"Chaudhry","sequence":"additional","affiliation":[{"name":"Division of Otolaryngology\u2013Head and Neck Surgery, Department of Surgery, University of Alabama at Birmingham, Birmingham, Alabama"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bradford A.","family":"Woodworth","sequence":"additional","affiliation":[{"name":"Division of Otolaryngology\u2013Head and Neck Surgery, Department of Surgery, University of Alabama at Birmingham, Birmingham, Alabama"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2014,1,1]]},"reference":[{"key":"bibr1-ar.2014.5.0073","doi-asserted-by":"publisher","DOI":"10.1258\/002221502761698801"},{"key":"bibr2-ar.2014.5.0073","doi-asserted-by":"publisher","DOI":"10.1016\/S0165-5876(86)80031-3"},{"key":"bibr3-ar.2014.5.0073","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2273.1978.tb00678.x"},{"key":"bibr4-ar.2014.5.0073","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100110059"},{"key":"bibr5-ar.2014.5.0073","doi-asserted-by":"publisher","DOI":"10.1017\/S002221510013991X"},{"key":"bibr6-ar.2014.5.0073","doi-asserted-by":"publisher","DOI":"10.1177\/0194599811432423"},{"key":"bibr7-ar.2014.5.0073","doi-asserted-by":"publisher","DOI":"10.1001\/archoto.2011.218"},{"key":"bibr8-ar.2014.5.0073","doi-asserted-by":"crossref","unstructured":"DurgamA., and BatraP.S.
