Summary In order to induce a serous otitis media in cats, the pharyngeal opening of the Eustachian tube was cauterized and obstructed on one side only through transpalatal approach; the other side remaind intact and served as control. On tympanic membrane examination and puncture 11 months later, there was fluid in the middle ear in three ears, no fluid in two ears, a tympanic membrane perforation in one ear and a red tympanic membrane in one ear. The middle ear was then ventilated through a plastic tube in two ears with and without fluid respectively. In all other ears, no tube was inserted. After another 7 months, the animals were intravitally perfused, and the middle ear mucosa biopsyed. The histological results of the light and electron microscopy showed chronic changes of the middle ear mucosa following experimental tubal obstruction.
