Patients with patulous Eustachian tube (ET) are bothered by the typical symptoms of severe fullness of the ear, autophony, respiratory tinnitus, etc. But the diagnosis was often regarded as stenosis of ET, and the symptoms were regarded as psychosomatic disorders due to the difficulty of diagnosis. Patulous ET was diagnosed by endoscopic video-monitor examination of the tympanic membrane and the pharyngeal orifice, sonotubometry, and the original questionnaire of the characteristic anamnesis. Among 224 patients with patulous ET, 208 patients were treated by therapeutic diagnosis of patulous ET; the cotton-tipped swab soaked in xylocain was inserted into the patulous pharyngeal orifice of the ET under the endoscopic technique. Closing the patulous ET, the bothersome symptoms such as severe fullness of the ear, autophony, and respiratory tinnitus dramatically disappeared and/or decreased, along with the additional symptoms such as stiffness of the neck and shoulder and many other equivocal complaints. It helps to relieve the anxiety troubling the minds of the patients. Furthermore, it is possible that a patient's patulous ET symptoms may be concealed by the retracted tympanic membrane and sensorineural hearing loss.<BR>The therapeutic diagnosis of patulous ET through review of the clinicai cases clarified the clinical evidence of patulous ET, and the results were discussed.
