The Ostmann fat pads (also known as Ostmann fatty bodies) are located inferolateral to the cartilaginous Eustachian tubes and are thought to be important in normal closure of eustachian tube, preventing transmission of nasopharyngeal pressure to the middle ear 5. Failure to visualize this thin triangular fat pad on MRI is a feature of patulous tube syndrome.
History and etymology
Named after (Friedrich Wilhelm) Paul Ostmann, German otologist (1859-1945) 4 who described his eponymous fat pads in 1893 3.
