Both patients presented to the ENT clinic, and both underwent the BrainLab protocol to generate computed tomography images for navigational reconstruction. Transnasal endoscopy was carried out with this guidance, and the implants were removed successfully in both cases. Previously used surgical techniques such as the Caldwell-Luc procedure or extraction through the tooth socket have higher rates of conversion to open procedures, more damage to the nasal sinuses and higher post-operative complication rates compared with the transnasal endoscopic approach.<\/jats:p><\/jats:sec><jats:sec id=\"S0022215109990958_sec4\"><jats:title>Conclusion:<\/jats:title><jats:p>Both patients underwent successful removal of their migrated dental implants with no complications, and neither required any follow-up intervention.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215109990958","type":"journal-article","created":{"date-parts":[[2009,9,1]],"date-time":"2009-09-01T04:42:58Z","timestamp":1251780178000},"page":"433-436","source":"Crossref","is-referenced-by-count":22,"title":["Image-guided, endoscopic removal of migrated titanium dental implants from maxillary sinus: two cases"],"prefix":"10.1017","volume":"124","author":[{"given":"H","family":"Ramotar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M-C","family":"Jaberoo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N K F","family":"Koo Ng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M A","family":"Pulido","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"H A","family":"Saleh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"56","published-online":{"date-parts":[[2009,9,1]]},"reference":[{"key":"S0022215109990958_ref7","first-page":"27","article-title":"Comparison of complications between endoscopic sinus surgery and Caldwell-Luc operation","volume":"180","author":"Ideka","year":"1996","journal-title":"J Exp Med"},{"key":"S0022215109990958_ref4","doi-asserted-by":"publisher","DOI":"10.1097\/01.id.0000156385.50768.cf"},{"key":"S0022215109990958_ref6","doi-asserted-by":"publisher","DOI":"10.1038\/sj.bdj.2008.293"},{"key":"S0022215109990958_ref2","doi-asserted-by":"publisher","DOI":"10.1016\/j.bjoms.2005.12.007"},{"key":"S0022215109990958_ref1","first-page":"291","article-title":"Migration of implants into the maxillary sinus: two clinical cases","volume":"20","author":"Galindo","year":"2005","journal-title":"Int J Oral Maxillofac Implants"},{"key":"S0022215109990958_ref8","first-page":"801","article-title":"Endoscopic retrieval of dental implants from the maxillary sinus","volume":"21","author":"Varol","year":"1996","journal-title":"Int J Oral Maxillofac Implants"},{"key":"S0022215109990958_ref5","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2007.01409.x"},{"key":"S0022215109990958_ref3","doi-asserted-by":"publisher","DOI":"10.1054\/ijom.2003.0470"}],"container-title":["The Journal of Laryngology &amp; Otology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022215109990958","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,4,28]],"date-time":"2019-04-28T16:22:43Z","timestamp":1556468563000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215109990958\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,9,1]]},"references-count":8,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2010,4]]}},"alternative-id":["S0022215109990958"],"URL":"https:\/\/doi.org\/10.1017\/s0022215109990958","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,9,1]]}}}
