Outline of Final Research Achievements

We tried animal explanation, however, did not acquire significant result. We next tried clinical evaluation of Patulous Eustachian tube patient and had good result as below. 1) Endoscope-assisted silicone plug insertion for patulous Eustachian tube patients. 2) Computed tomography findings of the bony portion of the Eustachian tube with or without patulous Eustachian tube patients. 3) Effectiveness of Kobayashi plug for 252 ears with chronic patulous Eustachian tube. 4) Tubal function tests with optional myringotomy detect Eustachian tube closing failure in acquired pars flaccida retraction cholesteatoma. 5) Relationship Between Clinical Test Results and Morphologic Severity Demonstrated by Sitting 3-D CT in Patients With Patulous Eustachian Tube.
