This case report is focused on the possibility of treating such a rare complication by means of endoscopic treatment through the nasal cavity.<\/jats:p><jats:p><jats:bold>Material and methods: <\/jats:bold> A 45\u2010year\u2010old female patient received one oral implant for the substitution of the left first upper molar, but during the surgical procedure the implant was displaced in the maxillary sinus. Owing to a delay in treatment, a spontaneous migration of the implant in the sphenoid sinus occurred.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> The implant was removed endoscopically through the nasal cavity: postoperative recovery was uneventful.<\/jats:p><jats:p><jats:bold>Conclusion: <\/jats:bold> To the authors' knowledge, this case represents the first report concerning migration of an oral implant into the sphenoid sinus and demonstrates the reliability and safety of an endoscopically driven surgical removal of the foreign body, thus preventing potential complications with extremely low postoperative morbidity.<\/jats:p>","DOI":"10.1111\/j.1600-0501.2007.01409.x","type":"journal-article","created":{"date-parts":[[2007,9,17]],"date-time":"2007-09-17T05:35:54Z","timestamp":1190007354000},"page":"776-780","source":"Crossref","is-referenced-by-count":72,"title":["Endoscopic removal of an unusual foreign body in the sphenoid sinus: an oral implant"],"prefix":"10.1111","volume":"18","author":[{"given":"Giovanni","family":"Felisati","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paolo","family":"Lozza","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Matteo","family":"Chiapasco","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Borloni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2007,9,14]]},"reference":[{"key":"e_1_2_4_2_1","first-page":"1","article-title":"The long\u2010term efficacy of currently used oral implants","volume":"1","author":"Albrektsson T.","year":"1986","journal-title":"The International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1998.090403.x"},{"key":"e_1_2_4_4_1","first-page":"157","article-title":"The endoscopic management of sphenoid and ethmoid mucoceles with orbital and intranasal extension","volume":"33","author":"Benninger M.S.","year":"1995","journal-title":"Rhinology"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1054\/jcms.2002.0279"},{"key":"e_1_2_4_6_1","first-page":"778","article-title":"On late sequelae of metallic foreign bodies in the region.
