The left tympanic membrane was swollen with a pulsatile tumor. Radiological investigations revealed a multilocular tumor in the inner ear extending into the middle ear and internal auditory canal (IAC). We performed a partial resection of the tumor by transmastoid approach to preserve the anatomical structure of the facial nerve. The tumor was pathologically diagnosed as SGCh. Two years after surgery, her facial function recovered to House-Brackmann Grade II and the residual tumor did not show regrowth on MRI. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> Although the natural course of this rare tumor is unknown, a partial resection is an acceptable treatment procedure when functional recovery of the facial nerve is anticipated. <\/jats:p><\/jats:sec><jats:sec><jats:title>Graphical abstract<\/jats:title><jats:p> <\/jats:p><\/jats:sec>","DOI":"10.1186\/s40463-021-00511-3","type":"journal-article","created":{"date-parts":[[2021,4,15]],"date-time":"2021-04-15T12:04:26Z","timestamp":1618488266000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Inner ear salivary gland choristoma extending to the middle ear with congenital profound hearing loss and facial palsy: A case report"],"prefix":"10.1177","volume":"50","author":[{"given":"Yoshiharu","family":"Yamanobe","sequence":"first","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, 160-8582, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8204-9518","authenticated-orcid":false,"given":"Naoki","family":"Oishi","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, 160-8582, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takanori","family":"Nishiyama","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, 160-8582, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Makoto","family":"Hosoya","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, 160-8582, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaoru","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology-Head and Neck Surgery, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, 160-8582, Tokyo, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,1,1]]},"reference":[{"key":"bibr1-s40463-021-00511-3","doi-asserted-by":"publisher","DOI":"10.1177\/019459989310800410"},{"key":"bibr2-s40463-021-00511-3","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215100082475"},{"key":"bibr3-s40463-021-00511-3","doi-asserted-by":"publisher","DOI":"10.1159\/000342793"},{"key":"bibr4-s40463-021-00511-3","doi-asserted-by":"publisher","DOI":"10.1080\/08820530500354052"},{"key":"bibr5-s40463-021-00511-3","doi-asserted-by":"publisher","DOI":"10.1288\/00005537-198402000-00017"},{"key":"bibr6-s40463-021-00511-3","doi-asserted-by":"publisher","DOI":"10.1177\/014556131509400211"},{"key":"bibr7-s40463-021-00511-3","doi-asserted-by":"publisher","DOI":"10.1016\/j.anl.2009.09.003"},{"key":"bibr8-s40463-021-00511-3","doi-asserted-by":"publisher","DOI":"10.1016\/j.wneu.2013.01.094"},{"issue":"2","key":"bibr9-s40463-021-00511-3","first-page":"93","volume":"258","author":"Dadas B","year":"2016","journal-title":"Eur Arch Otorhinolaryngol"},{"issue":"5","key":"bibr10-s40463-021-00511-3","first-page":"461","volume":"11","author":"Ziari K","year":"2016","journal-title":"Iran J Pathol"},{"key":"bibr11-s40463-021-00511-3","first-page":"47","volume":"3","author":"Nassar MN","year":"2007","journal-title":"Mediterr J Otol"}],"container-title":["Journal of Otolaryngology - Head &amp;
