Complication rates in this case series were significantly lower with increasing experience of the surgeon. Active middle-ear implants should be considered in appropriate patients with moderate-to-severe sensorineural hearing loss who have struggled with conventional amplification and are good surgical candidates.<\/jats:p><\/jats:sec>","DOI":"10.1017\/s0022215121000335","type":"journal-article","created":{"date-parts":[[2021,3,22]],"date-time":"2021-03-22T07:01:25Z","timestamp":1616396485000},"page":"304-309","source":"Crossref","is-referenced-by-count":2,"title":["Totally implantable active middle-ear implants: a large, single-surgeon cohort"],"prefix":"10.1017","volume":"135","author":[{"given":"E","family":"McCarty Walsh","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D R","family":"Morrison","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"W J","family":"McFeely","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2021,3,22]]},"reference":[{"key":"S0022215121000335_ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2018.11.011"},{"key":"S0022215121000335_ref14","doi-asserted-by":"publisher","DOI":"10.1001\/archotol.132.11.1210"},{"key":"S0022215121000335_ref4","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e3181cabd42"},{"key":"S0022215121000335_ref12","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-016-4361-2"},{"key":"S0022215121000335_ref8","doi-asserted-by":"publisher","DOI":"10.1002\/lary.26602"},{"key":"S0022215121000335_ref10","doi-asserted-by":"publisher","DOI":"10.1007\/s00405-013-2811-7"},{"key":"S0022215121000335_ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2018.11.002"},{"key":"S0022215121000335_ref5","doi-asserted-by":"crossref","first-page":"303","DOI":"10.1055\/s-0033-1363463","article-title":"Implantable and semi-implantable hearing AIDS: a review of history, indications, and surgery","volume":"18","author":"Bittencourt","year":"2014","journal-title":"Int Arch Otorhinolaryngol"},{"key":"S0022215121000335_ref15","doi-asserted-by":"publisher","DOI":"10.1097\/MAO.0b013e31825f230d"},{"key":"S0022215121000335_ref18","doi-asserted-by":"publisher","DOI":"10.1159\/000338689"},{"key":"S0022215121000335_ref9","doi-asserted-by":"publisher","DOI":"10.14639\/0392-100X-1146"},{"key":"S0022215121000335_ref13","doi-asserted-by":"publisher","DOI":"10.1179\/1467010014Z.000000000163"},{"key":"S0022215121000335_ref7","doi-asserted-by":"publisher","DOI":"10.1080\/00016489.2018.1472807"},{"key":"S0022215121000335_ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.otc.2014.08.006"},{"key":"S0022215121000335_ref1","doi-asserted-by":"publisher","DOI":"10.1001\/archinternmed.2011.506"},{"key":"S0022215121000335_ref2","doi-asserted-by":"publisher","DOI":"10.1097\/01.AUD.0000069226.22983.80"},{"key":"S0022215121000335_ref19","doi-asserted-by":"publisher","DOI":"10.3109\/00016489.2013.868602"},{"key":"S0022215121000335_ref16","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0110636"},{"key":"S0022215121000335_ref6","doi-asserted-by":"publisher","DOI":"10.1002\/lary.27246"},{"key":"S0022215121000335_ref11","doi-asserted-by":"publisher","DOI":"10.1017\/S0022215113001151"}],"container-title":["The Journal of Laryngology &amp; Otology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.cambridge.org\/core\/services\/aop-cambridge-core\/content\/view\/S0022215121000335","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2021,5,26]],"date-time":"2021-05-26T13:14:00Z","timestamp":1622034840000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.cambridge.org\/core\/product\/identifier\/S0022215121000335\/type\/journal_article"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2021,3,22]]},"references-count":20,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2021,4]]}},"alternative-id":["S0022215121000335"],"URL":"https:\/\/doi.org\/10.1017\/s0022215121000335","relation":{},"ISSN":["0022-2151","1748-5460"],"issn-type":[{"value":"0022-2151","type":"print"},{"value":"1748-5460","type":"electronic"}],"subject":[],"published":{"date-parts":[[2021,3,22]]}}}
