Sound localization was measured by asking patients to point as quickly and accurately as possible with a head-mounted LED in the perceived sound direction. Loudspeakers, positioned around the listener within a range of +73\u00b0\/\u221273\u00b0 in the horizontal plane, were not visible to the patients. Broadband (500 Hz\u201320 kHz) noise bursts (150 ms), roved over a 20-dB range in 10 dB steps was presented. MEIs stimulate the ipsilateral cochlea only and therefore the localization response was not affected by crosstalk. Sound localization was better with bilateral MEIs compared with the unilateral left and unilateral right conditions. Good sound localization performance was found in the bilaterally aided hearing condition in four patients. In two patients, localization abilities equaled normal hearing performance. Interestingly, in the unaided condition, when both devices were turned off, subjects could still localize the stimuli presented at the highest sound level. Comparison with data of patients implanted bilaterally with bone-conduction devices, demonstrated that localization abilities with MEIs were superior. The measurements demonstrate that patients with BCHL, using remnant binaural cues in the unaided condition, are able to process binaural cues when listening with bilateral MEIs. We conclude that implantation with two MEIs, each stimulating only the ipsilateral cochlea, without crosstalk to the contralateral cochlea, can result in good sound localization abilities, and that this topic needs further investigation.<\/jats:p>","DOI":"10.1177\/23312165241264466","type":"journal-article","created":{"date-parts":[[2024,8,6]],"date-time":"2024-08-06T15:48:00Z","timestamp":1722959280000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["The Merits of Bilateral Application of Middle Ear Implants in Patients With Bilateral Conductive and\/or Mixed Hearing Loss"],"prefix":"10.1177","volume":"28","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7933-6962","authenticated-orcid":false,"given":"Martijn J.H.","family":"Agterberg","sequence":"first","affiliation":[{"name":"Department Otorhinolaryngology, Utrecht Department of Otorhinolaryngology, Head and Neck Surgery, University Medical Center Utrecht, Utrecht, the Netherlands"},{"name":"Department of Otorhinolaryngology, Donders Institute for Brain, Cognition and Behaviour, Radboud University Medical Centre Nijmegen, Nijmegen, the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Louise","family":"Straatman","sequence":"additional","affiliation":[{"name":"Department Otorhinolaryngology, Utrecht Department of Otorhinolaryngology, Head and Neck Surgery, University Medical Center Utrecht, Utrecht, the Netherlands"},{"name":"Department Otorhinolaryngology, University Medical Center (UMC) Utrecht Brain Center, Utrecht, the Netherlands"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Karl-Ludwig","family":"Bruchhage","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital Schleswig-Holstein, L\u00fcbeck, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1481-6997","authenticated-orcid":false,"given":"Tim","family":"J\u00fcrgens","sequence":"additional","affiliation":[{"name":"Institute of Acoustics, University of Applied Sciences L\u00fcbeck, L\u00fcbeck, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniela","family":"Hollfelder","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital Schleswig-Holstein, L\u00fcbeck, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anke","family":"Leichtle","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital Schleswig-Holstein, L\u00fcbeck, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2024,8,6]]},"reference":[{"key":"bibr1-23312165241264466","doi-asserted-by":"publisher","DOI":"10.1159\/000323587"},{"key":"bibr2-23312165241264466","doi-asserted-by":"publisher","DOI":"10.1007\/s10162-010-0235-2"},{"key":"bibr3-23312165241264466","doi-asserted-by":"publisher","DOI":"10.1016\/j.heares.2018.04.007"},{"key":"bibr4-23312165241264466","doi-asserted-by":"publisher","DOI":"10.1007\/s00221-022-06333-7"},{"key":"bibr5-23312165241264466","volume-title":"Spatial hearing.
