Eustachian tube (ET) dysfunction can lead to otitis media. Multiple\ncauses of ET dysfunction exist; ET obstruction is one of them. Osseous obliteration of ET is quite\nrare. In the literature, there are two cases of solitary osteoma and a case of hamartoma with an osseous\ncontent in the ET. Herein, this report describes the case of a patient with multiple osseous lesions\nconsistent with osteomas in the ET, causing ipsilateral otitis media with CT findings.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Case Report:<\/jats:title>\n<jats:p>A 53-year-old woman presented with left-sided intermittent otalgia and otorrhea.\nTemporal bone computed tomography showed opacification of middle ear consistent with otitis media\nand nearly complete blockage of the left ET lumen with multiple osseous lesions wall probably\nconsistent with osteomas on the left side.<\/jats:p>\n<\/jats:sec>\n<jats:sec>\n<jats:title>Conclusion:<\/jats:title>\n<jats:p>There are limited data about the radiological features of ET osteoma due to its rare occurrence.\nRadiographically, external ear osteoma generally appears as a single pedunculated hyperdense\nmass on CT scan originating from the tympanosquamous or tympanomastoid suture line and\nextending into the auditory canal with otherwise preserved canal dimensions. Considering this information,\nosseous lesions arising from ET bone wall and extending into the lumen in the present\ncase were considered as osteomas. Especially in the case of unilateral chronic otitis media, ET\nshould not remain a neglected anatomical area.<\/jats:p>\n<\/jats:sec>","DOI":"10.2174\/1573405616666200606215737","type":"journal-article","created":{"date-parts":[[2020,6,6]],"date-time":"2020-06-06T19:37:37Z","timestamp":1591472257000},"page":"1052-1054","update-policy":"https:\/\/doi.org\/10.2174\/bsp_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Multiple Osteomas of Eustachian Tube Causing Ipsilateral Otitis Media"],"prefix":"10.2174","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1560-964X","authenticated-orcid":true,"given":"Suzan","family":"Saylisoy","sequence":"first","affiliation":[{"name":"Department of Radiology, Faculty of Medicine, Eskisehir Osmangazi University, Eskisehir, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"965","reference":[{"key":"ref=1","doi-asserted-by":"publisher","first-page":"493","DOI":"10.1007\/s12070-011-0372-x","volume":"65","author":"Sharma K.","year":"2013","unstructured":"Sharma K.; Manjari M.; Salaria N.; Middle ear cleft in chronic otitis media: a clinicohistopathological study.
