The tympanic duct, also known as the tympanic canal or tympanic space, is a structure in the inner ear, specifically in the cochlea. The cochlea is a spiral-shaped organ responsible for hearing, and it contains three fluid-filled chambers: the scala vestibuli, scala tympani, and scala media (cochlear duct). The tympanic duct typically refers to the scala tympani, which is the lower chamber of the cochlea.
