Abstract

The air in the middle ear cleft serves as an air cushion with its tympano-ossicular system serving to match the impedance of the inner ear fluids and thus compensate for the loss of sound energy during transmission in media of different densities. The tympanic membrane on one side and the pressure equalizing eustachian tube on the other are the vital constituents of this cleft. The embryology and components developing from the ecto, meso and endoderm layers are elaborated upon.
