This form of siderosis is caused by chronic cerebral hemorrhages, especially subarachnoid hemorrhages. The diversity of symptoms depends on the respective damage to the brain, but in most of the cases it shows up as incipient unilateral or bilateral hearing loss, ataxia and signs of pyramidal tracts. We are investigating the question of whether cochlear implantation is a treatment option for patients with superficial hemosiderosis and which strategy of diagnostic procedure has to be ruled out preoperatively.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Materials and methods<\/jats:title>\n                <jats:p>In a tertiary hospital between 2009 and 2018, we examined (<jats:italic>N<\/jats:italic>\u2009=\u20095) patients with radiologically confirmed central hemosiderosis who suffered from profound hearing loss to deafness were treated with a cochlear implant (CI).

The results are below the average for all postlingual deaf CI patients. Superficial siderosis causes neural damages, which explains the reduced speech understanding based on central hearing loss. It is important to correctly weigh the patient's expectations preoperatively and to include neurologists within the therapy procedure.<\/jats:p>\n              <\/jats:sec>","DOI":"10.1007\/s00405-021-07198-2","type":"journal-article","created":{"date-parts":[[2021,12,20]],"date-time":"2021-12-20T18:02:49Z","timestamp":1640023369000},"page":"4363-4370","update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Cochlea implantation in patients with superficial hemosiderosis"],"prefix":"10.1007","volume":"279","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5742-6825","authenticated-orcid":false,"given":"E.","family":"Artukarslan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3953-112X","authenticated-orcid":false,"given":"F.","family":"Matin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F.","family":"Donnerstag","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.","family":"G\u00e4rtner","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9307-5989","authenticated-orcid":false,"given":"T.","family":"Lenarz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1057-0245","authenticated-orcid":false,"given":"A.","family":"Lesinski-Schiedat","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"297","published-online":{"date-parts":[[2021,12,20]]},"reference":[{"issue":"3","key":"7198_CR1","doi-asserted-by":"publisher","first-page":"249","DOI":"10.1097\/00005072-198805000-00005","volume":"47","author":"AH Koeppen","year":"1988","unstructured":"Koeppen AH, Dentinger MP (1988) Brain hemosiderin and superficial siderosis of the central nervous system.
