We evaluated the functional results and QoL after CI in a heterogeneous patient cohort with emphasis on patients with long-term deafness (&gt;10 years). Methods: Twenty-eight patients (n = 32 implanted ears, within n = 12 long-term deaf ears) implanted with a mid-scala electrode array were included in this retrospective mono-centric cohort study. Speech intelligibility for monosyllables (SIM), speech reception thresholds (SRT50) and QoL with Nijmegen Cochlear Implant Questionnaire (NCIQ) were registered. Correlation of SIM and QoL was analyzed. Results: SIM and SRT50 improved significantly 12 months postoperatively up to 54.8 \u00b1 29.1% and 49.3 \u00b1 9.6 dB SPL, respectively. SIM progressively improved up to 1 year, but some early-deafened, late implanted patients developed speech understanding several years after implantation. The global and all subdomain QoL scores increased significantly up to 12 months postoperatively and we found a correlation of SIM and global QoL score at 12 months postoperatively. Several patients of the \u201cpoor performer\u201d (SIM &lt; 40%) group reported high improvement of hearing-related QoL. Conclusions: Cochlear implantation provides a benefit in hearing-related QoL, even in some patients with low postoperative speech intelligibility results. Consequently, hearing-related QoL scores should be routinely used as outcome measure beside standard speech understanding tests, as well. Further studies with a prospective multi-centric design are needed to identify factors influencing post-implantation functional results and QoL in the patient group of long-term deafness.<\/jats:p>","DOI":"10.3390\/jcm11175156","type":"journal-article","created":{"date-parts":[[2022,9,1]],"date-time":"2022-09-01T01:50:51Z","timestamp":1661997051000},"page":"5156","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":19,"title":["Functional Outcomes and Quality of Life after Cochlear Implantation in Patients with Long-Term Deafness"],"prefix":"10.3390","volume":"11","author":[{"given":"Attila","family":"Ovari","sequence":"first","affiliation":[{"name":"Department of Oto-Rhino-Laryngology, Head and Neck Surgery, Plastic Surgery, Asklepios Klinik St. Georg, 20099 Hamburg, Germany"},{"name":"Asklepios Medical School, Semmelweis University, 20099 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lisa","family":"H\u00fchnlein","sequence":"additional","affiliation":[{"name":"Asklepios Medical School, Semmelweis University, 20099 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David","family":"Nguyen-Dalinger","sequence":"additional","affiliation":[{"name":"Asklepios Medical School, Semmelweis University, 20099 Hamburg, Germany"},{"name":"Hanseatisches Cochlea Implantat Zentrum (HCIZ), 22417 Hamburg, Germany"},{"name":"Department of Oto-Rhino-Laryngology, Head and Neck Surgery, Facial Plastic Surgery, Asklepios Klinik Nord-Heidberg, 22417 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel Fabian","family":"Str\u00fcder","sequence":"additional","affiliation":[{"name":"Department of Oto-Rhino-Laryngology, Head and Neck Surgery \u201cOtto Koerner\u201d, University Medical Center, 18057 Rostock, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christoph","family":"K\u00fclkens","sequence":"additional","affiliation":[{"name":"Asklepios Medical School, Semmelweis University, 20099 Hamburg, Germany"},{"name":"Hanseatisches Cochlea Implantat Zentrum (HCIZ), 22417 Hamburg, Germany"},{"name":"Department of Oto-Rhino-Laryngology, Head and Neck Surgery, Facial Plastic Surgery, Asklepios Klinik Nord-Heidberg, 22417 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oliver","family":"Niclaus","sequence":"additional","affiliation":[{"name":"Asklepios Medical School, Semmelweis University, 20099 Hamburg, Germany"},{"name":"Hanseatisches Cochlea Implantat Zentrum (HCIZ), 22417 Hamburg, Germany"},{"name":"Department of Oto-Rhino-Laryngology, Head and Neck Surgery, Facial Plastic Surgery, Asklepios Klinik Nord-Heidberg, 22417 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jens Eduard","family":"Meyer","sequence":"additional","affiliation":[{"name":"Department of Oto-Rhino-Laryngology, Head and Neck Surgery, Plastic Surgery, Asklepios Klinik St. Georg, 20099 Hamburg, Germany"},{"name":"Asklepios Medical School, Semmelweis University, 20099 Hamburg, Germany"},{"name":"Hanseatisches Cochlea Implantat Zentrum (HCIZ), 22417 Hamburg, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,8,31]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"698","DOI":"10.1097\/00129492-200209000-00016","article-title":"Cochlear implantation for adolescents and adults with prelinguistic deafness","volume":"23","author":"Schramm","year":"2002","journal-title":"Otol.
