Gliederung

Text

Introduction: To study pathways of aeration to different compartments of the new- borne middle ear related with the presence of amniotic fluid.

Methods: 65 new-borne temporal bones were dissected end sectioned with surgical otomicroscope. The epitympanic compartments and the anatomy of the atticotympanic diaphragm were studied. The presence of amniotic fluid was noted. The most important details were photographed.

Results: According to Palva, the most important folds in the middle ear were tensor fold and lateral incudomalleal fold. In the ear with fluid content, it was granulation tissue blocking the tympanic isthmus. In those ears, there were other duplicate folds well represented.

Conclusion: The presence of amniotic fluid in tympanic isthmus and posterior pouch may lead to formation of granulation tissue and blockage of the aeration pathways to epitympanic compartments and to Prussak's space.

Blockage of the aeration pathways to the attic may cause the conditions for chronic media ottitis .
