It is well to review the anatomy of the eustachian tube from time to time and to tie it in with new concepts of its function, pathology, and methods of treating abnormal and diseased states.
The protympanum or bony portion of the eustachian tube is the site of some tubal occlusions and we are concerned with normal structures so that we can deal better with the abnormal and the diseased.
The structure of the mobile cartilaginous tube makes an interesting study particularly with the play of adjacent muscles and supporting structures. To know anatomy is basic to understanding function and both are necessary to interpret and to treat the diseases of the eustachian tube.
