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.

Claim (Index 1):
A method for regenerating the tympanic membrane or ear canal of a subject having a cholesteatoma, ear canal tumor or an ear canal that is narrow in shape, comprising:\n (a) removing a cholesteatoma or tumor from the ear canal of a subject or wounding a narrow ear canal, thereby generating a wound; (b) contacting the wound with a gelatin sponge that carries a therapeutically effective amount of basic fibroblast growth factor (bFGF); and (c) applying fibrin glue to the gelatin sponge as a covering material, thereby regenerating the tympanic membrane or ear canal of a subject having a cholesteatoma.
