Abstract
Provided is a tympanic membrane or ear canal regeneration agent comprising a combination of a gelatin sponge that carries basic fibroblast growth factor (bFGF) and a covering material. The covering material is used not only to fix the gelatin sponge to the affected portion, but also for the purpose of preventing drying and infections to provide a culturing environment that is favorable for regenerating tissue isolated from the outside. To promote tissue regeneration, the margin of the tympanic membrane or ear canal defect is preferably freshened in advance.
