In mapping, it is important to decide both the behavioral threshold levels (T level) and comfort levels (C level). Decisions about C levels are often difficult because they depend on the response of each subject, especially in prelmgual hearing-loss children who have never experienced any sense of sound. Measurement of the electrically evoked stapedius reflex (ESR) and ESR threshold (ESRT) has the potential for deciding the C level because of its involuntary nature, and hence could be of assistance to such children. Thus, intraoperative and postoperative electrically evoked stapedius reflex thresholds (IOESRTs and POESRTs) and initial behavioral comfortable levels (C level) were investigated. Twenty-one subjects who had undergone cochlear implantation under general anesthesia in our institute, were entered into the study. Nucleus【○!R】 (N22), Nucleus 【○!R】24 (N24) , and Clarion^TM 16 (CLN) systems were implanted in six, eight, and seven cases respectively. The selected volatile agents were sevoflurane (in 16 cases), and isoflurane in the remaining cases. In eleven of the subjects (52.4%), intraoperative ESR was recognized. In the N24 group six cases (75%) of the intraoperative ESR was determined however ESR rarely appeared in any of the CLN group (14.3%). There were higher IOESRTs than POESRTs. IOESRTs were mostly higher than POESRTs and this might have been caused by the volatile agent. The relationship between IOESRTs and POESRTs and initial C levels was shown to be an almost linear function in each individual. This tendency was remarkable in that electrodes were placed in median sides, whereas POESRTs and C levels did not differ obviously in its apical side. We suggest that estimated C levels in median sides obtained from IOESRTs and POESRTs in apical sides might be valuable as a mapping reference. In the case of N24, the relationship between the concentration of sevoflurane and ESRTs appeared to be linear. Furthermore, POESRTs were in accordance with the estimated ESRTs at 0% sevoflurane. Further study concerning ESRTs is needed for better cochlear implant use.","subitem_description_type":"Other"},{"subitem_description":"論文","subitem_description_type":"Other"}]},"item_1617186643794":{"attribute_name":"Publisher","attribute_value_mlt":[{"subitem_1522300295150":"ja","subitem_1522300316516":"琉球医学会"},{"subitem_1522300295150":"en","subitem_1522300316516":"Ryukyu Medical Association"}]},"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":"1346888X"},{"subitem_1522646500366":"ISSN","subitem_1522646572813":"0289-1530"},{"subitem_1522646500366":"NCID","subitem_1522646572813":"AN10369445"}]},"item_1617186941041":{"attribute_name":"Source Title","attribute_value_mlt":[{"subitem_1522650068558":"ja","subitem_1522650091861":"琉球医学会誌 = Ryukyu Medical Journal"}]},"item_1617187056579":{"attribute_name":"Bibliographic Information","attribute_value_mlt":[{"bibliographicIssueNumber":"3-4","bibliographicPageEnd":"141","bibliographicPageStart":"133","bibliographicVolumeNumber":"21"}]},"item_1617258105262":{"attribute_name":"Resource Type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_1617265215918":{"attribute_name":"Version Type","attribute_value_mlt":[{"subitem_1522305645492":"VoR","subitem_1600292170262":"http://purl.org/coar/version/c_970fb48d4fbd8a85"}]},"item_1617605131499":{"attribute_name":"File","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","filename":"v21p133.pdf","mimetype":"application/pdf","url":{"objectType":"fulltext","url":"https://u-ryukyu.repo.nii.ac.jp/record/2016174/files/v21p133.pdf"},"version_id":"0423cf80-9683-4dbf-bce8-b3c6c2619d76"}]},"item_title":"[原著］A Study of Electrically Evoked Stapedius Reflex Threshold and Comfort Level in Cochlear Implant Patients","item_type_id":"15","owner":"1","path":["1642838218204","1642838412624"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2010-07-02"},"publish_date":"2010-07-02","publish_status":"0","recid":"2016174","relation_version_is_last":true,"title":["[原著］A Study of Electrically Evoked Stapedius Reflex Threshold and Comfort Level in Cochlear Implant Patients"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2022-02-22T04:16:07.760019+00:00"}
