A safety evaluation of dexamethasone-releasing cochlear implants: Comparative study on the risk of otogenic meningitis after implantation

Abstract

There was no significant difference in meningitis risk between the two groups. In the group with non-eluting implants, 3 of 15 animals developed meningitis, while in the group with dexamethasone-eluting implants 4 of 15 showed signs of meningitis. In this study dexamethasone-releasing implants did not significantly increase the risk of postoperative pneumococcal otogenic meningitis.
