A profile curve (Hounsfield units) was used to measure stapes footplate thickness along a perpendicular line across the stapes footplate in a plane parallel to the lateral semicircular canal.\nResults: Footplate thickness was smaller at the midpoint than just before the anterior crus and just\nafter the posterior crus. Interobserver variability was lowest at the midpoint, where foot plate thickness was significantly greater in the affected ear in otosclerosis patients compared with controls (0.60 ± 0.09 mm vs 0.46 ± 0.04 mm; p \u003c .001). Otosclerosis patients were detected using U-HRCT with a high area under the curve. Difficulty in the stapes opening procedure correlated with stapes footplate thickness.\nConclusions: Footplate thickness on U-HRCT correlated with temporal bone anatomy and corresponded to surgical difficulty.\nSignificance: U-HRCT-derived anatomic data is useful for evaluating the stapes.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "琉球大学"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "University of the Ryukyus"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "eng"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "1651-2251"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "en", "subitem_1522650091861": "Acta Oto-Laryngologica"}]}, "item_1617187056579": {"attribute_name": "Bibliographic Information", "attribute_value_mlt": [{"bibliographicIssueNumber": "11", "bibliographicPageEnd": "903", "bibliographicPageStart": "899", "bibliographicVolumeNumber": "140"}]}, "item_1617187087799": {"attribute_name": "Dissertation Number", "attribute_value_mlt": [{"subitem_1551256171004": "甲第516号"}]}, "item_1617187112279": {"attribute_name": "Degree Name", "attribute_value_mlt": [{"subitem_1551256126428": "博士(医学)", "subitem_1551256129013": "ja"}]}, "item_1617187136212": {"attribute_name": "Date Granted", "attribute_value_mlt": [{"subitem_1551256096004": "2020-12-18"}]}, "item_1617258105262": {"attribute_name": "Resource Type", "attribute_value_mlt": [{"resourcetype": "doctoral thesis", "resourceuri": "http://purl.org/coar/resource_type/c_db06"}]}, "item_1617265215918": {"attribute_name": "Version Type", "attribute_value_mlt": [{"subitem_1522305645492": "VoR", "subitem_1600292170262": "http://purl.org/coar/version/c_970fb48d4fbd8a85"}]}, "item_1617353299429": {"attribute_name": "Relation", "attribute_value_mlt": [{"subitem_1522306287251": {"subitem_1522306382014": "DOI", "subitem_1522306436033": "https://doi.org/10.1080/00016489.2020.1788225"}}]}, "item_1617605131499": {"attribute_name": "File", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2022-06-03"}], "download_preview_message": "", "file_order": 0, "filename": "iken516abstract.pdf", "filesize": [{"value": "1003 KB"}], "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 1003000.0, "url": {"objectType": "abstract", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2018007/files/iken516abstract.pdf"}, "version_id": "84296197-a6af-43f1-b07b-908956c9e0f3"}, {"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2022-06-03"}], "download_preview_message": "", "file_order": 1, "filename": "iken516review.pdf", "filesize": [{"value": "864 KB"}], "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 864000.0, "url": {"objectType": "other", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2018007/files/iken516review.pdf"}, "version_id": "9f6ab442-9fd5-4212-bcca-bbb581f27b9e"}, {"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2022-06-03"}], "download_preview_message": "", "file_order": 2, "filename": "iken516text.pdf", "filesize": [{"value": "1.2 MB"}], "future_date_message": "", "is_thumbnail": false, "mimetype": "", "size": 1200000.0, "url": {"objectType": "fulltext", "url": "https://u-ryukyu.repo.nii.ac.jp/record/2018007/files/iken516text.pdf"}, "version_id": "ea1b2cce-6abe-430d-bbc2-a54356b6195a"}]}, "item_1617944105607": {"attribute_name": "Degree Grantor", "attribute_value_mlt": [{"subitem_1551256015892": [{"subitem_1551256027296": "18001", "subitem_1551256029891": "kakenhi"}], "subitem_1551256037922": [{"subitem_1551256042287": "琉球大学", "subitem_1551256047619": "ja"}]}]}, "item_title": "Measurement of stapes footplate thickness in otosclerosis using ultra-high-resolution computed tomography", "item_type_id": "59", "owner": "8", "path": ["1642838159351", "1642838409905"], "permalink_uri": "http://hdl.handle.net/20.500.12000/0002018007", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2022-06-03"}, "publish_date": "2022-06-03", "publish_status": "0", "recid": "2018007", "relation": {}, "relation_version_is_last": true, "title": ["Measurement of stapes footplate thickness in otosclerosis using ultra-high-resolution computed tomography"], "weko_shared_id": -1}
