This approach becomes limited when access is required to the more proximal geniculate ganglion and labyrinthine portion of the facial nerve. The aim of this report was to determine the feasibility of a transmastoid endoscopically assisted approach to the geniculate ganglion and labyrinthine facial nerve.\u00a0This is an endoscopic cadaveric dissection and video review at a university anatomical laboratory. <\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p> A total of 12 endoscopic cadaveric dissections were performed. A cortical mastoidectomy and perilabyrinthine air cell removal was performed using an operating microscope. Beyond this, dissection was performed with an endoscope. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> In all dissections, an endoscopically assisted transmastoid approach allowed complete access to the geniculate ganglion, and at least 1.5\u00a0mm of the distal labyrinthine facial nerve. Further transcrusal drilling through the anterior crus of the superior semicircular canal allowed access to the entire labyrinthine facial nerve. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> The entire geniculate ganglion and labyrinthine facial nerve is difficult to access with microscopic techniques. Adding endoscopic visualization allows for complete visualization of the geniculate ganglion. Clinical reports will further strengthen these preliminary cadaveric results. <\/jats:p><\/jats:sec>","DOI":"10.1186\/s40463-017-0231-1","type":"journal-article","created":{"date-parts":[[2017,8,22]],"date-time":"2017-08-22T12:44:55Z","timestamp":1503405895000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":16,"title":["Endoscopically-assisted transmastoid approach to the geniculate ganglion and labyrinthine facial nerve"],"prefix":"10.1177","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3962-0819","authenticated-orcid":false,"given":"Nicholas","family":"Jufas","sequence":"first","affiliation":[{"name":"Division of Otolaryngology \u2013 Head and Neck Surgery, Dalhousie University, 3rd Floor Dickson Building, VG Site, QE II Health Sciences Centre, 5820 University Ave, B3H 2Y9, Halifax, NS, Canada"},{"name":"Kolling Deafness Research Centre, University of Sydney and Macquarie University, Sydney, Australia"},{"name":"Sydney Endoscopic Ear Surgery (SEES) Research Group, Sydney, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Manohar","family":"Bance","sequence":"additional","affiliation":[{"name":"Division of Otolaryngology \u2013 Head and Neck Surgery, Dalhousie University, 3rd Floor Dickson Building, VG Site, QE II Health Sciences Centre, 5820 University Ave, B3H 2Y9, Halifax, NS, Canada"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2017,1,1]]},"reference":[{"key":"bibr1-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1177\/014556130208100509"},{"key":"bibr2-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.25203"},{"key":"bibr3-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.21819"},{"key":"bibr4-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.3109\/00016489.2013.764468"},{"key":"bibr5-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000000988"},{"key":"bibr6-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.1972.00770080529008"},{"key":"bibr7-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.3109\/00016489109137396"},{"issue":"3","key":"bibr8-s40463-017-0231-1","first-page":"248039","volume":"2013","author":"Gupta S","year":"2013","journal-title":"Radiol Res Pract"},{"key":"bibr9-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1177\/000348940010900303"},{"key":"bibr10-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1227\/01.NEU.0000368102.22612.47"},{"key":"bibr11-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.3171\/jns.2001.94.4.0660"},{"key":"bibr12-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200407000-00029"},{"key":"bibr13-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.5005\/jp\/books\/11530"},{"key":"bibr14-s40463-017-0231-1","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198203000-00008"}],"container-title":["Journal of Otolaryngology - Head &amp; Neck Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1186\/s40463-017-0231-1","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1186\/s40463-017-0231-1","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/link.springer.com\/content\/pdf\/10.1186\/s40463-017-0231-1.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"similarity-checking"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1186\/s40463-017-0231-1","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,3,10]],"date-time":"2025-03-10T22:32:44Z","timestamp":1741645964000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1186\/s40463-017-0231-1"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2017,1]]},"references-count":14,"journal-issue":{"issue":"1","published-print":{"date-parts":[[2017,1]]}},"alternative-id":["10.1186\/s40463-017-0231-1"],"URL":"https:\/\/doi.org\/10.1186\/s40463-017-0231-1","relation":{},"ISSN":["1916-0216","1916-0216"],"issn-type":[{"value":"1916-0216","type":"print"},{"value":"1916-0216","type":"electronic"}],"subject":[],"published":{"date-parts":[[2017,1]]},"article-number":"53"}}
