IVRO resulted in antero-inferior repositioning of the mandibular head with an increase in the joint space. Clinical signs and symptoms were improved in all cases, but disc position was unchanged. In five joints, a double contour line of the mandibular head was observed on CT. In conclusion, it was considered that this procedure was effective in alleviating signs and symptoms of patients with reducible disc displacement of the TMJ, and it was suggested that the condylar position to the articular fossa played a more important role in appearance of signs and symptoms than the disc position in these patients.", "subitem_description_type": "Abstract"}, {"subitem_description": "顎関節内障、復位を伴う関節円板前方転位症例に対する下顎枝垂直骨切り術(IVRO)の効果機序を明らかにすることを目的に、側斜位経頭蓋撮影法およびCTを用いて手術前後の顎関節部の骨形態変化や下顎頭･関節円板の位置変化について画像的に検討した｡対象は、顎関節症状を主訴に新潟大学歯学部附属病院第二口腔外科を受診し、復位を伴う関節円板前方転位の診断にて、IVROを施行した8名(男性1名、女性7名)9関節である。症例の手術時年齢は17～25歳(平均20.0歳)、術後の再調査までの期間は6～20か月(平均10.2か月)であった。その結果、術後患側下顎頭は前下方に移動し、関節隙の拡大が認められた｡術前に認められた顎関節症状は術後には完全に消失したが、全例関節円板は依然復位を伴う前方転位の状態を呈していた｡また、5関節で下顎頭後上方の骨添加像が観察された｡以上の結果から、復位を伴う関節円板前方転位症例にIVROを施行した際、関節円板の解剖学的な整位が得られなくとも、術後の下顎頭の位置変化に伴い関節隙が拡大することにより顎関節症状が改善されるものと考えられた｡", "subitem_description_type": "Abstract"}]}, "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": "Matsushita, Takeshi"}], "nameIdentifiers": [{"nameIdentifier": "153079", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Takagi, Ritsuo"}], "nameIdentifiers": [{"nameIdentifier": "153080", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Hayashi, Takafumi"}], "nameIdentifiers": [{"nameIdentifier": "153081", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ito, Jusuke"}], "nameIdentifiers": [{"nameIdentifier": "153082", "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": "NS_26(1)_13-20.pdf", "filesize": [{"value": "6.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 6700000.0, "url": {"label": "NS_26(1)_13-20.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/25931/files/NS_26(1)_13-20.pdf"}, "version_id": "0479d66f-8cc8-4ae2-9295-48a36e995c27"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "temporomandibular joint (TMJ)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "reducible disc displacement", "subitem_subject_scheme": "Other"}, {"subitem_subject": "intraoral vertical ramus osteotomy (IVRO)", "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": "departmental bulletin paper", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Imaging Analysis of the Temporomandibular Joint after Intraoral Vertical Ramus Osteotomy for Treatment of Patients with Reducible Disc Displacement", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "Imaging Analysis of the Temporomandibular Joint after Intraoral Vertical Ramus Osteotomy for Treatment of Patients with Reducible Disc Displacement"}, {"subitem_title": "Imaging Analysis of the Temporomandibular Joint after Intraoral Vertical Ramus Osteotomy for Treatment of Patients with Reducible Disc Displacement", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1326"], "permalink_uri": "http://hdl.handle.net/10191/22958", "pubdate": {"attribute_name": "公開日", "attribute_value": "2013-08-21"}, "publish_date": "2013-08-21", "publish_status": "0", "recid": "25931", "relation": {}, "relation_version_is_last": true, "title": ["Imaging Analysis of the Temporomandibular Joint after Intraoral Vertical Ramus Osteotomy for Treatment of Patients with Reducible Disc Displacement"], "weko_shared_id": null}
