Five patients presented with infection and an exposed cochlear implant
and we decided to salvage them by attempting use of new antimicrobial
treatment for biofilms using betaine surfactant and polyhexanide along
with wound debridement and double layered vascularized flap. This is the
first study demonstrating the use of betaine surfactant and polyhexanide
in the management of biofilm in cochlear implants and we could salvage
four infected cochlear implants by the aforementioned method. Early
intervention can significantly improve salvage outcomes in cochlear
implants infected with biofilms.
