Delayed-onset facial paralysis following cochlear implantation: a case study and comprehensive analysis.

Objectives: Cochlear implantation (CI) is a surgical intervention used to rehabilitate hearing in individuals, both pediatric and adult, with severe hearing loss. It is generally a safe procedure with rare postoperative complications. Facial nerve paralysis following cochlear implant surgery poses challenges in diagnosis and treatment.

Methods: This case report details a 48-year-old male who experienced delayed facial paralysis after cochlear implantation, an uncommon occurrence with limited documentation.

Results: The facial nerve palsy of the patient resolved by the third week with combined therapy.

Discussion: The etiology of this complication is not fully understood, with latent virus reactivation, particularly HSV and VZV, hypothesized as a probable cause.

Conclusion: Successful management involves a combination of corticosteroids, antiviral therapy, and antibiotics, leading to a favorable outcome.
