It is generally detected with magnetic resonance imaging (MRI), which is associated with higher cost, less availability, and possible need for sedation. Therefore, identifying computed tomography (CT) findings, such as cochlear aperture stenosis (CAS), that can reliably predict CND is valuable. Our study aimed to determine the prevalence of CND in pediatric patients with CT\u2010diagnosed CAS.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Retrospective study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Setting<\/jats:title><jats:p>Tertiary care center.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We included pediatric patients diagnosed with CAS on temporal bone CT and with available temporal bone MRI. For each patient, an otolaryngologist and a pediatric neuroradiologist measured the cochlear aperture width on CT to confirm CAS (cochlear aperture\u2009&lt;\u20091.4\u2009mm) and assessed the status of the cochlear nerve on MRI.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Fifty\u2010five patients, representing 65 ears, had CAS on CT measurement. Median cochlear aperture width in CAS ears was 0.70\u2009mm (interquartile\u00a0range [IQR]: 0.40\u20101.05\u2009mm) versus 2.00\u2009mm in non\u2010CAS ears (IQR: 1.80\u20102.30\u2009mm, <jats:italic>P<\/jats:italic>\u2009&lt;\u2009.001). CND was found in 98.5% (n\u2009=\u200964\/65) of CAS ears, while a normal cochlear nerve was found in 1.5% (n\u2009=\u20091\/65) of CAS ears.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>CND is highly prevalent among pediatric patients with CAS. This suggests that MRI may not be needed to assess for CND in USNHL patients with CAS, as initial CT may provide sufficient information to determine cochlear implant candidacy. We recommend thoughtful shared decision\u2010making with parents of USNHL patients when determining whether to pursue MRI in the setting of a CAS diagnosis.<\/jats:p><\/jats:sec>","DOI":"10.1002\/ohn.774","type":"journal-article","created":{"date-parts":[[2024,4,12]],"date-time":"2024-04-12T05:59:15Z","timestamp":1712901555000},"page":"872-877","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["High Prevalence of Cochlear Nerve Deficiency in Pediatric Patients With Cochlear Aperture Stenosis"],"prefix":"10.1002","volume":"171","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4333-9763","authenticated-orcid":false,"given":"Christina","family":"Dorismond","sequence":"first","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Vanderbilt University Medical Center Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8361-1143","authenticated-orcid":false,"given":"Miriam R.","family":"Smetak","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Washington University School of Medicine in St Louis St Louis Missouri USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth L.","family":"Perkins","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Vanderbilt University Medical Center Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5927-9734","authenticated-orcid":false,"given":"Alexandra M.","family":"Foust","sequence":"additional","affiliation":[{"name":"Department of Radiology, Monroe Carell Jr. Children's Hospital Vanderbilt University Medical Center Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Asha","family":"Sarma","sequence":"additional","affiliation":[{"name":"Department of Radiology, Monroe Carell Jr. Children's Hospital Vanderbilt University Medical Center Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3746-0820","authenticated-orcid":false,"suffix":"Jr","given":"Frank W.","family":"Virgin","sequence":"additional","affiliation":[{"name":"Department of Otolaryngology\u2013Head and Neck Surgery Vanderbilt University Medical Center Nashville Tennessee USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2024,4,12]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003446-200004000-00005"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1044\/1059-0889(2011\/10-0049)"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016489.2011.554440"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.3109\/14992027.2012.673237"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003446-198602000-00007"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2013.01.014"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.23454"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1542\/peds.2009-2448"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1177\/00034894211019519"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1002\/lary.28095"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1177\/0194599813487681"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1097\/AUD.0000000000001204"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1097\/01.mao.0000281804.36574.72"},{"key":"e_1_2_8_15_1","article-title":"Imaging and audiological features of children with cochlear nerve deficiency","author":"Chen W","year":"2022","journal-title":"Ear Nose Throat J"},{"key":"e_1_2_8_16_1","doi-asserted-by":"publisher","DOI":"10.1002\/ohn.255"},{"key":"e_1_2_8_17_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2016.07.023"},{"key":"e_1_2_8_18_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11940-018-0536-z"},{"key":"e_1_2_8_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijporl.2012.12.031"},{"key":"e_1_2_8_20_1","doi-asserted-by":"publisher","DOI":"10.1080\/00016480252775724"},{"issue":"10","key":"e_1_2_8_21_1","doi-asserted-by":"crossref","first-page":"776","DOI":"10.1177\/000348949510401005","article-title":"Surface\u2010coil magnetic resonance imaging of the internal auditory canal and the inner ear.
