Color Atlas of the Anatomy and Pathology of the Epitympanum

Edition: 1st., 2001
This atlas gives a detailed documentation of the superior compartments of the middle ear. New microdissection approaches have been developed, most importantly anterior microdissection. In addition to the tympanic cavity, this approach allows a direct view into the anterior membrane of Prussak's space, the anterior surface of the tensor fold, and the supratubal recess, areas not explored earlier. The regular and hitherto unknown auxiliary aeration and drainage pathways are shown in detail. Aeration of Prussak's space is documented using both microdissection and serial sections; these pathways from the mesotympanum or from the lower lateral attic are independent of the tympanic isthmus. The pathology caused by chronic inflammation on the aeration and drainage routes is also documented, and new surgical microdissection methods for removal of the tensor fold are described.
