However, radiological evaluation and intra-operative findings confirmed a stapes footplate fistula in the non-implanted ear. Surgical closure was achieved using temporal fascia and fibrin glue. In one case, subtotal petrosectomy was required because of persistent cerebrospinal fluid leakage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S0022215126104617_sec4d\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In patients with incomplete partition type I malformations undergoing cochlear implantation, contralateral cerebrospinal fluid fistula should be considered in the differential diagnosis of post-operative meningitis.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1017\/s0022215126104617","type":"journal-article","created":{"date-parts":[[2026,3,27]],"date-time":"2026-03-27T09:45:12Z","timestamp":1774604712000},"page":"622-625","source":"Crossref","is-referenced-by-count":0,"title":["Challenges in Cerebrospinal Fluid Fistula with Contralateral Cochlear Implant in Incomplete Partition Type I: A Case Series"],"prefix":"10.1017","volume":"140","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6846-4475","authenticated-orcid":false,"given":"Ergin","family":"Ero\u011flu","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04kwvgz42","id-type":"ROR","asserted-by":"publisher"}],"name":"Hacettepe University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Muhammed \u00c7a\u011fr\u0131","family":"K\u00fclek\u00e7i","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04kwvgz42","id-type":"ROR","asserted-by":"publisher"}],"name":"Hacettepe University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R\u0131dvan","family":"K\u0131l\u0131\u00e7","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/041jyzp61","id-type":"ROR","asserted-by":"publisher"}],"name":"Van Y\u00fcz\u00fcnc\u00fc Y\u0131l University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Levent","family":"Sennaro\u011flu","sequence":"additional","affiliation":[{"id":[{"id":"https:\/\/ror.org\/04kwvgz42","id-type":"ROR","asserted-by":"publisher"}],"name":"Hacettepe University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2026,3,27]]},"reference":[{"key":"S0022215126104617_ref11","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000004591"},{"key":"S0022215126104617_ref3","doi-asserted-by":"publisher","DOI":"10.4274\/tao.2021.6180"},{"key":"S0022215126104617_ref8","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2019.05.045"},{"key":"S0022215126104617_ref7","doi-asserted-by":"publisher","DOI":"10.1002\/cii.416"},{"key":"S0022215126104617_ref9","doi-asserted-by":"publisher","DOI":"10.1177\/0194599820934748"},{"key":"S0022215126104617_ref5","first-page":"56","article-title":"Cochlear implant in incomplete partition type I","volume":"33","author":"Berrettini","year":"2013","journal-title":"Acta Otorhinolaryngol Ital"},{"key":"S0022215126104617_ref10","doi-asserted-by":"publisher","DOI":"10.1179\/1754762815Y.0000000016"},{"key":"S0022215126104617_ref15","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-025-09431-8"},{"key":"S0022215126104617_ref1","doi-asserted-by":"publisher","DOI":"10.4274\/balkanmedj.2017.0367"},{"key":"S0022215126104617_ref14","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000000898"},{"key":"S0022215126104617_ref6","doi-asserted-by":"crossref","first-page":"e11","DOI":"10.1097\/MAO.0000000000000606","article-title":"Surgical outcomes after cochlear implantation in children with incomplete partition type I: comparison with deaf children with a normal inner ear structure","volume":"36","author":"Suk","year":"2015","journal-title":"Otol Neurotol"},{"key":"S0022215126104617_ref2","doi-asserted-by":"publisher","DOI":"10.1177\/0145561320920399"},{"key":"S0022215126104617_ref13","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2022.111215"},{"key":"S0022215126104617_ref4","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2020.110525"},{"key":"S0022215126104617_ref12","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-019-05534-1"}],"container-title":["The Journal of Laryngology &amp;
