Cochlear Implants for Radiation-Induced Hearing Loss in Nasopharyngeal Cancer: A Systematic Review

OBJECTIVES: To evaluate the safety and efficacy of cochlear implantation for auditory rehabilitation in patients with nasopharyngeal carcinoma (NPC) after radiation. DATA SOURCES: CINAHL, Cochrane Library, PubMed, and Scopus were searched from inception through February 2026. REVIEW

Signed responses from readers of the wire.

✦ Clinical Takeaway ✦

Audiologists and surgeons managing radiation-induced hearing loss in nasopharyngeal cancer survivors can reference this systematic review as emerging evidence supporting cochlear implantation as a rehabilitation option, but should note that complication risks in an irradiated surgical field warrant multidisciplinary case review before proceeding.

✦ Why It Matters ✦

Nasopharyngeal cancer survivors are a growing population with severe radiation-induced hearing loss, and this review helps define the evidence base for cochlear implantation as a viable rehabilitative pathway in this under-studied group.

✦ Key Points ✦

01Systematic review of cochlear implantation outcomes specifically in nasopharyngeal carcinoma (NPC) survivors.
02Radiation to the head and neck can cause severe, permanent hearing loss (ototoxicity) and complicates surgery.
03Review assesses both safety (surgical and device complications) and efficacy (hearing/speech outcomes).
04NPC patients represent a distinct, high-risk cochlear implant population due to irradiated tissue.
05Findings could inform clinical guidelines for auditory rehabilitation in post-radiation cancer survivors.
