Официальное название

Long-term Follow-up of a Cohort of Adult CI632D and CI632 Participants in the CLTD5759 CI-DEX Study

Обзор

A long-term follow-up of Cochlear's cochlear implant electrode array which passively elutes dexamethasone for a defined period of time to help reduce inflammatory responses.
