The radiological demonstration of the malleus and incus should be possible in most technically satisfactory films of the mastoid process.The authors have not been able to demonstrate the stapes with any degree of consistency.The submento-vertical and the Towne's position are the most useful positions for the examination of the ossicles although the handle of the malleus can be readily seen in the lateral view.Anatomical features likely to be mistaken for the shadows of the ossicles are discussed.Pathological changes involving the ossicles, developmental absence, destruction by infection and growths and displacement by trauma are discussed.
