Preclinical evaluation of thermoreversible triamcinolone acetonide hydrogels for drug delivery to the inner ear.Intratympanic glucocorticoid therapy aims to reduce the side effects associated with systemic long-time therapy of inner ear diseases or traumata after cochlear implantation.  For that purpose, thermoreversible hydrogels being fluid at room temperature but solid at body temperature are known to be appropriate drug delivery systems.
