She had a history of dental implantation for an unerupted tooth on the right side 3 years ago. Physical examination including flexible nasendoscopy demonstrated yellow debris in the right middle meatus. CT paranasal sinuses demonstrated a radiopaque lesion in the right anterior ethmoid sinus and resembled the unerupted tooth. The tooth was removed endoscopically from the right nasal cavity without complications. This case highlights the importance of eliciting an accurate dental history and considering ectopic dentition as a differential diagnosis in a patient with unilateral symptoms of sinusitis.<\/jats:p>","DOI":"10.1136\/bcr-2020-237858","type":"journal-article","created":{"date-parts":[[2021,2,22]],"date-time":"2021-02-22T11:35:39Z","timestamp":1613993739000},"page":"e237858","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":1,"title":["Endoscopic removal of ectopic dentition in ethmoid sinus"],"prefix":"10.1136","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8983-0075","authenticated-orcid":false,"given":"Amy SM","family":"Wong","sequence":"first","affiliation":[{"name":"Otolaryngology, Epworth Healthcare Richmond, Melbourne, Victoria, Australia"},{"name":"Otolaryngology, Northern Health, Melbourne, VIC, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9065-8962","authenticated-orcid":false,"given":"Jagdeep S","family":"Virk","sequence":"additional","affiliation":[{"name":"Head and Neck, Peter MacCallum Cancer Centre, Melbourne, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0296-4060","authenticated-orcid":false,"given":"Matthew J R","family":"Magarey","sequence":"additional","affiliation":[{"name":"Otolaryngology, Epworth Healthcare Richmond, Melbourne, Victoria, Australia"},{"name":"Head and Neck, Peter MacCallum Cancer Centre, Melbourne, Victoria, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,2,22]]},"reference":[{"key":"2025082710413802000_14.2.e237858.1","doi-asserted-by":"crossref","first-page":"30","DOI":"10.1186\/s40463-019-0353-8","article-title":"Endoscopic removal of ectopic sinonasal teeth: a systematic review","volume":"48","author":"Levin","year":"2019","journal-title":"J Otolaryngol Head Neck Surg"},{"key":"2025082710413802000_14.2.e237858.2","doi-asserted-by":"crossref","first-page":"360","DOI":"10.1111\/cid.12099","article-title":"Accidental migration of a dental implant into the ethmoid sinus following a transalveolar sinus elevation procedure","volume":"17","author":"Bakhshalian","year":"2015","journal-title":"Clin Implant Dent Relat Res"},{"key":"2025082710413802000_14.2.e237858.3","doi-asserted-by":"crossref","first-page":"1594","DOI":"10.1016\/j.ijom.2019.07.013","article-title":"Dental implant and fungus ball in the ethmoid sinus","volume":"48","author":"Lee","year":"2019","journal-title":"Int J Oral Maxillofac Surg"},{"key":"2025082710413802000_14.2.e237858.4","doi-asserted-by":"crossref","first-page":"667","DOI":"10.1177\/014556130108000912","article-title":"Endoscopic removal of an ectopic third molar obstructing the osteomeatal complex","volume":"80","author":"Hasbini","year":"2001","journal-title":"Ear Nose Throat J"},{"key":"2025082710413802000_14.2.e237858.5","first-page":"220","article-title":"Tooth in ethmoid sinus: a case report","volume":"34","author":"Shishegar","year":"2009","journal-title":"Iran J Med Sci"},{"key":"2025082710413802000_14.2.e237858.6","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijom.2009.06.013"},{"key":"2025082710413802000_14.2.e237858.7","doi-asserted-by":"crossref","first-page":"S234","DOI":"10.4103\/0975-7406.100216","article-title":"Impacted canines: etiology, diagnosis, and orthodontic management","volume":"4","author":"Manne","year":"2012","journal-title":"J Pharm Bioallied Sci"},{"key":"2025082710413802000_14.2.e237858.8","doi-asserted-by":"crossref","DOI":"10.1186\/1752-1947-8-334","article-title":"The retrieval of unerupted teeth in pedodontics: two case reports","volume":"8","author":"Tecco","year":"2014","journal-title":"J Med Case Rep"},{"key":"2025082710413802000_14.2.e237858.9","doi-asserted-by":"publisher","DOI":"10.14219\/jada.archive.2000.0236"},{"key":"2025082710413802000_14.2.e237858.10","doi-asserted-by":"crossref","first-page":"642","DOI":"10.1055\/s-0039-1697213","article-title":"Implants placement in contact with dental tissue: a potential paradigm shift?
