The cohort included 353 males (58.6%) and 249 females (41.4%). Revision surgery was required in 28 cases (4.7%), primarily due to device failure (17\/28, 60.7%), including 14 hard and 3 soft failures. Kaplan-Meier analysis showed CI survival rates of 99.1%, 98.1%, 96.7%, 96.4%, and 96.4% at 1, 2, 3, 5, and 10\u2009years post-surgery, respectively. The log-rank test identified sex, age, and history of head trauma as significant factors affecting device survival (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u2009.05).

Male children who undergo cochlear implantation at \u22643\u2009years of age or have a history of postoperative head trauma require enhanced postoperative care. This includes avoiding vigorous head impacts and increasing follow-up visits to monitor device function and speech recovery. Manufacturers should prioritize developing more durable, impact-resistant cochlear implants to reduce failure rates and improve long-term device survival.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/00034894251325955","type":"journal-article","created":{"date-parts":[[2025,3,12]],"date-time":"2025-03-12T07:42:53Z","timestamp":1741765373000},"page":"511-517","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Device Survival After Pediatric Cochlear Implant Surgery: A 15-Year Single-Center Retrospective Analysis"],"prefix":"10.1177","volume":"134","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5517-0718","authenticated-orcid":false,"given":"Bin","family":"Xu","sequence":"first","affiliation":[{"name":"Department of ENT and Head and Neck Surgery, Children\u2019s Hospital, Zhejiang University School of Medicine, National Clinical Research Center for Child Health, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4570-2973","authenticated-orcid":false,"given":"Yong","family":"Fu","sequence":"additional","affiliation":[{"name":"Department of ENT and Head and Neck Surgery, Children\u2019s Hospital, Zhejiang University School of Medicine, National Clinical Research Center for Child Health, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Bi","sequence":"additional","affiliation":[{"name":"Department of ENT and Head and Neck Surgery, Children\u2019s Hospital, Zhejiang University School of Medicine, National Clinical Research Center for Child Health, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenxin","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of ENT and Head and Neck Surgery, Children\u2019s Hospital, Zhejiang University School of Medicine, National Clinical Research Center for Child Health, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lulu","family":"Yu","sequence":"additional","affiliation":[{"name":"Department of ENT and Head and Neck Surgery, Children\u2019s Hospital, Zhejiang University School of Medicine, National Clinical Research Center for Child Health, Hangzhou, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,3,12]]},"reference":[{"key":"e_1_3_2_2_2","volume-title":"World Report on Hearing","author":"World Health Organization","year":"2021","unstructured":"World Health Organization.
