We here describe a case of bilateral progressive sensorineural hearing loss (SNHL) due to intracranial hypotension caused by an undiagnosed spontaneous CSF leak from a skull base defect in a middle-aged woman. To the best of our knowledge, this is the first report describing a SNHL in a patient affected by SIH secondary to sphenoidal CSF leak.<\/jats:p>","DOI":"10.1177\/01455613231191372","type":"journal-article","created":{"date-parts":[[2023,8,8]],"date-time":"2023-08-08T06:28:08Z","timestamp":1691476088000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Bilateral Sensorineural Hearing Loss Related to a Skull Base Spontaneous Cerebrospinal Fluid Leak: A Case Report and Literature Review"],"prefix":"10.1177","volume":"104","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0882-8892","authenticated-orcid":false,"given":"Lorenzo Maria","family":"Gaini","sequence":"first","affiliation":[{"name":"Fondazione IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico, Department of Otolaryngology and Head and Neck Surgery, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ludovica","family":"Battilocchi","sequence":"additional","affiliation":[{"name":"Fondazione IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico, Department of Otolaryngology and Head and Neck Surgery, Milan, Italy"},{"name":"Department of Clinical Sciences and Community Health, University of Milan, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Giorgio","family":"Conte","sequence":"additional","affiliation":[{"name":"Fondazione IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico, Neuroradiology Unit, Milan, Italy"},{"name":"University of Milan, Department of Medical-Surgical Physiopathology and Transplantation, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michele","family":"Gaffuri","sequence":"additional","affiliation":[{"name":"Fondazione IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico, Department of Otolaryngology and Head and Neck Surgery, Milan, Italy"},{"name":"Department of Clinical Sciences and Community Health, University of Milan, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Diego","family":"Zanetti","sequence":"additional","affiliation":[{"name":"Department of Clinical Sciences and Community Health, University of Milan, Milan, Italy"},{"name":"Fondazione IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico, Audiology Unit, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lorenzo","family":"Pignataro","sequence":"additional","affiliation":[{"name":"Fondazione IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico, Department of Otolaryngology and Head and Neck Surgery, Milan, Italy"},{"name":"Department of Clinical Sciences and Community Health, University of Milan, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8461-6042","authenticated-orcid":false,"given":"Sara","family":"Torretta","sequence":"additional","affiliation":[{"name":"Fondazione IRCCS Ca\u2019 Granda Ospedale Maggiore Policlinico, Department of Otolaryngology and Head and Neck Surgery, Milan, Italy"},{"name":"Department of Clinical Sciences and Community Health, University of Milan, Milan, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2023,8,8]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF00453677"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/000348940211100910"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1159\/000500658"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2010.05.007"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000001377"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000002665"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0196-0709(83)80071-4"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.otohns.2005.03.087"},{"key":"e_1_3_2_10_2","first-page":"31","article-title":"A thin line between Meniere\u2019s disease and spontaneous intracranial hypotension syndrome","volume":"13","author":"Botica I","year":"2016","unstructured":"Botica I, Vrca A, \u0160pero M, et al.
