Only cases with available computed tomography prior to second stage cochlear or middle ear implantation were included. The occlusive material was either muscle tissue or oxidized regenerated cellulose in combination with bone wax. On 3D multiplanar image reconstruction, the varying topographic interrelation of the cochlea and the petrous carotid artery was measured and categorized into two groups: detachment or overlapping.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>In 9 (31%) of the 29 included cases there was insufficient occlusion of the ET. In none of these cases was an infection of the fat filling in the obliterated cavity observed during the implantation procedure on second stage (average 10 months interval). The failure rate of both occlusion materials was almost the same (using muscle tissue, in 4 (33.3%) of 12 or oxidized regenerated cellulose, in 5 (29.4%) of 17 cases). It was also similar for both materials in each of the anatomic variation groups.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>An incomplete occlusion of the ET alone does not appear to lead to an infection of the obliterated cavity. Autologous muscle tissue and oxidized regenerated cellulose had similar rates of ET occlusion failure. The topographical variance of the protympanum appears to have no direct influence on the success of the ET occlusion.<\/jats:p><\/jats:sec>","DOI":"10.1002\/lio2.478","type":"journal-article","created":{"date-parts":[[2020,10,21]],"date-time":"2020-10-21T13:11:12Z","timestamp":1603285872000},"page":"1140-1146","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Impact of occlusive material and cochlea\u2010carotid artery relation on eustachian tube occlusion in subtotal petrosectomy"],"prefix":"10.1002","volume":"5","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6399-2081","authenticated-orcid":false,"given":"Stefan","family":"Lyutenski","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology Hannover Medical School  Hannover Germany"},{"name":"Department of Otorhinolaryngology Helios Hospital Berlin\u2010Buch  Berlin Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sabri","family":"El\u2010Saied","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Hannover Medical School  Hannover Germany"},{"name":"Department of Otolaryngology \u2010 Head and Neck Surgery Soroka University Medical Center  Be'er Sheva Israel"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Burkard","family":"Schwab","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology Hannover Medical School  Hannover Germany"},{"name":"Department of Otorhinolaryngology Helios Hospital Hildesheim  Hildesheim Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2020,10,21]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.26533"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e318289841b"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-016-4005-6"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1055\/s-2008-1058571"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0000000000000702"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.mao.0000265187.45216.71"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/000348948409300620"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1177\/000348948609500102"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1097\/00129492-200309000-00003"},{"key":"e_1_2_8_11_1","doi-asserted-by":"crossref","DOI":"10.1007\/978-3-642-73061-0","volume-title":"Surgery of the Skull Base: An Interdisciplinary Approach","author":"Samii M","year":"1989"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-199610000-00014"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-012-2113-5"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1080\/14670100.2019.1667068"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jot.2019.03.005"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200210000-00013"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200404000-00011"},{"key":"e_1_2_8_18_1","first-page":"335","article-title":"Tubal and tympanic openings of the peritubal cells: implications for cerebrospinal fluid otorhinorrhea","volume":"17","author":"Saim L","year":"1996","journal-title":"Am J Otol"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1808-8694(15)31191-5"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005537-200305000-00007"},{"key":"e_1_2_8_21_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.5541040515"},{"key":"e_1_2_8_22_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016488509182260"},{"key":"e_1_2_8_23_1","doi-asserted-by":"publisher","DOI":"10.1111\/coa.12712"},{"key":"e_1_2_8_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2010.03.005"},{"volume-title":"Anatomy of the Temporal Bone with Surgical Implications","year":"1986","author":"Schuknecht HF","key":"e_1_2_8_25_1"},{"key":"e_1_2_8_26_1","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215118001172"},{"volume-title":"Microsurgery of the Skull Base","year":"1988","author":"Fisch U","key":"e_1_2_8_27_1"},{"key":"e_1_2_8_28_1","doi-asserted-by":"crossref","first-page":"193","DOI":"10.1177\/15910199060120S134","article-title":"Yamada net al.
