Subjects comprised 17 patients diagnosed as skeletal mandibular prognathism with deviation. Volume rendering technic facilitated extraction of masseter muscle from the three-dimensional image with CT, and enabled us to perform volume measurement of masseter muscle precisely. There was no significant correlation between three-dimensional ratio of mandibular deviation and volume difference of masseter muscle in deviated and the opposite side (r=-0.35). In addition, volume of masseter muscles in the deviated side might not necessarily be larger than that in the contralateral side. This finding suggests that morphological difference of masseter muscles in between deviated side and the opposite side is not necessarily observed in the jaw deformity patients with facial asymmetry.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "150629", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Wakamatsu, Takanori"}]}, {"nameIdentifiers": [{"nameIdentifier": "150630", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hanada, Kooji"}]}, {"nameIdentifiers": [{"nameIdentifier": "150631", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Hayashi, Takafumi"}]}, {"nameIdentifiers": [{"nameIdentifier": "150632", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Saito, Isao"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟歯学会"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN0018300X", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03850153", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "若松, 孝典"}], "nameIdentifiers": [{"nameIdentifier": "150625", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "花田, 晃治"}], "nameIdentifiers": [{"nameIdentifier": "150626", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "林, 孝文"}], "nameIdentifiers": [{"nameIdentifier": "150627", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "齋藤, 功"}], "nameIdentifiers": [{"nameIdentifier": "150628", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "ファイル情報", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-08-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "8_0003.pdf", "filesize": [{"value": "705.8 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 705800.0, "url": {"label": "8_0003.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/25550/files/8_0003.pdf"}, "version_id": "958045f6-5342-408e-a2b8-a102c016dbbd"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Volume rendering 法", "subitem_subject_scheme": "Other"}, {"subitem_subject": "下顎偏位率", "subitem_subject_scheme": "Other"}, {"subitem_subject": "咬筋体積", "subitem_subject_scheme": "Other"}, {"subitem_subject": "volume rendering technic", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "three-dimensional ratio of mandibular deviation", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}, {"subitem_subject": "volume of masseter muscle", "subitem_subject_language": "en", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "言語", "attribute_value_mlt": [{"subitem_language": "jpn"}]}, "item_resource_type": {"attribute_name": "資源タイプ", "attribute_value_mlt": [{"resourcetype": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Volume rendering法を用いた偏位を伴う顎変形症患者における咬筋の体積計測", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Volume rendering法を用いた偏位を伴う顎変形症患者における咬筋の体積計測"}, {"subitem_title": "Volume rendering法を用いた偏位を伴う顎変形症患者における咬筋の体積計測", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1305"], "permalink_uri": "http://hdl.handle.net/10191/1332", "pubdate": {"attribute_name": "公開日", "attribute_value": "2007-04-23"}, "publish_date": "2007-04-23", "publish_status": "0", "recid": "25550", "relation": {}, "relation_version_is_last": true, "title": ["Volume rendering法を用いた偏位を伴う顎変形症患者における咬筋の体積計測"], "weko_shared_id": null}
