Data Sources: Systematic searches were conducted in PubMed, Web of Science, Scopus, and Embase from inception through to June 2025. Review Methods: A systematic review adhering to PRISMA guidelines was performed. Included studies reported CI outcomes in DS patients receiving otolaryngologic care for SNHL. Extracted data included findings on ear anatomy, auditory performance, speech\/language development, intelligibility, and duration of CI use. Results: A total of 149 abstracts were screened, yielding six studies with 26 patients that met the inclusion criteria. The review included pediatric DS patients with documented ages at implantation spanning from 11 months to 17.9 years. CI provided significant benefits for DS patients, including improved audiometric results, enhanced environmental awareness, and psychosocial gains. Optimal outcomes were associated with early implantation, thorough preoperative imaging (CT\/MRI), and management of middle ear disease. Variability in outcomes often reflected cognitive limitations and anatomical challenges such as cochlear nerve hypoplasia and Eustachian tube dysfunction. Conclusions: CI can significantly improve quality of life and communication in children with DS when tailored to their unique needs. Preoperative imaging is essential to assess candidacy, and middle ear disease should be addressed prior to surgery. Clinicians should counsel families with individualized goals that emphasize functional hearing gains over normative speech benchmarks. Broader adoption of CI in this population may be supported by standardized, population-sensitive outcome measures and future prospective studies.<\/jats:p>","DOI":"10.3390\/audiolres16020044","type":"journal-article","created":{"date-parts":[[2026,3,9]],"date-time":"2026-03-09T11:06:52Z","timestamp":1773054412000},"page":"44","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cochlear Implantation in Down Syndrome: Functional Outcomes, Challenges, and Management Strategies"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-7603-5574","authenticated-orcid":false,"given":"David H.","family":"Elisha","sequence":"first","affiliation":[{"name":"Hearing Research and Cochlear Implant Laboratory, Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, FL 33136, USA"},{"name":"Faculty of Medicine, Tel Aviv University, Tel Aviv 6997801, Israel"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David H.","family":"Cohen","sequence":"additional","affiliation":[{"name":"Hearing Research and Cochlear Implant Laboratory, Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrea","family":"Monterrubio","sequence":"additional","affiliation":[{"name":"Hearing Research and Cochlear Implant Laboratory, Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan","family":"Hossain","sequence":"additional","affiliation":[{"name":"Hearing Research and Cochlear Implant Laboratory, Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, FL 33136, USA"},{"name":"Herbert Wertheim College of Medicine, Florida International University, Miami, FL 33199, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9423-8823","authenticated-orcid":false,"given":"Nicholas","family":"DiStefano","sequence":"additional","affiliation":[{"name":"Hearing Research and Cochlear Implant Laboratory, Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rahul","family":"Mittal","sequence":"additional","affiliation":[{"name":"Hearing Research and Cochlear Implant Laboratory, Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, FL 33136, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adrien A.","family":"Eshraghi","sequence":"additional","affiliation":[{"name":"Hearing Research and Cochlear Implant Laboratory, Department of Otolaryngology, University of Miami Miller School of Medicine, Miami, FL 33136, USA"},{"name":"Department of Neurological Surgery, University of Miami Miller School of Medicine, Miami, FL 33136, USA"},{"name":"Department of Biomedical Engineering, University of Miami, Coral Gables, Miami, FL 33146, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,3,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"182","DOI":"10.1016\/j.ijporl.2018.07.007","article-title":"Down Syndrome as an indicator for pediatric otolaryngologic procedures","volume":"112","author":"Patel","year":"2018","journal-title":"Int.
