Methods: Two-stage tympanoplasty with mastoidectomy was performed in four cases of unilateral cholesteatoma with sclerotic mastoid. During the first-stage operation, small fragments of autologous cortical bone were inserted into the cavity after mastoidectomy to form a honeycomb-like structure. Reconstruction of the lateral wall of the mastoid cavity was performed using the mastoid cortical bony plate. Pre- and postoperative mastoid volume was evaluated by three-dimensional reconstruction based on high-resolution computed tomography (HR-CT) images. Results: HR-CT images after the first-stage operation showed that mastoid volume had increased in all subjects. Macroscopic inspection during the second-stage operation revealed that the honeycomb-like structure made of bony fragments and covered by thin mucosa in the mastoid cavity was stable, with no evidence of effusion or granulation tissue. No retraction of the eardrum, middle ear effusion or recurrence of cholesteatoma was observed, and the hearing level on a pure-tone audiogram was improved in any subject 60 - 94 months after the second-stage operation. Conclusion: Surgical construction and regeneration of mastoid air cells using autologous cortical bone can be useful in treatment of cholesteatoma with arrested mastoid pneumatization.","subitem_description_type":"Abstract"}]},"item_2_description_63":{"attribute_name":"引用","attribute_value_mlt":[{"subitem_description":"Surgical Science, 3(11), pp.514-517; 2012","subitem_description_type":"Other"}]},"item_2_publisher_33":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Scientific Research Publishing Inc."}]},"item_2_relation_12":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.4236/ss.2012.311102","subitem_relation_type_select":"DOI"}}]},"item_2_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"c 2015 by authors and Scientific Research Publishing Inc."},{"subitem_rights":"This work and the related PDF file are licensed under a Creative Commons Attribution 4.0 International License."}]},"item_2_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21579407","subitem_source_identifier_type":"ISSN"}]},"item_2_source_id_8":{"attribute_name":"EISSN","attribute_value_mlt":[{"subitem_source_identifier":"21579415","subitem_source_identifier_type":"ISSN"}]},"item_2_version_type_16":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kaneko, Kenichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanemaru, Shin-ichi"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Kanai, Rie"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"Atsushi, Yamada"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2020-12-21"}],"displaytype":"detail","filename":"SS3_514.pdf","filesize":[{"value":"718.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"SS3_514.pdf","url":"https://nagasaki-u.repo.nii.ac.jp/record/4153/files/SS3_514.pdf"},"version_id":"96b591e1-6598-4c20-91af-f7922c081b7f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Regeneration","subitem_subject_scheme":"Other"},{"subitem_subject":"Mastoid Air Cells","subitem_subject_scheme":"Other"},{"subitem_subject":"Mastoid Cortex Plasty","subitem_subject_scheme":"Other"},{"subitem_subject":"Tissue Engineering","subitem_subject_scheme":"Other"},{"subitem_subject":"Cholesteatoma","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Regeneration of Mastoid Air Cells in Vivo Using Autologous Cortical Bone","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Regeneration of Mastoid Air Cells in Vivo Using Autologous Cortical Bone"}]},"item_type_id":"2","owner":"2","path":["30"],"pubdate":{"attribute_name":"公開日","attribute_value":"2015-05-01"},"publish_date":"2015-05-01","publish_status":"0","recid":"4153","relation_version_is_last":true,"title":["Regeneration of Mastoid Air Cells in Vivo Using Autologous Cortical Bone"],"weko_creator_id":"2","weko_shared_id":-1},"updated":"2023-05-16T03:25:24.667467+00:00"}
