Abstract

The patients with patulous Eustachian tube presented with aural fullness, autophonia and audition of breathing sound in the ear, mainly due to the direct entry of sound created within the body to the ear through a patent Eustachian tube. In this study, we studied the patients visited our hospital during April 2004 to March 2010, according to the followings, age at first visit, symptoms, the cause of patulous Eustachian tube, auditory condition, and treatments.<br>A total of 41 patients visited and treated in our hospital and their ages ranged from 16 to 83 years (mean ± SD, 49.0 ± 20.2 years). They complained with aural fullness and autophonia in 76 % and 73 % of the patients, respectively. In contrast, 51% of the patients suffered from breathing sound in the ear. The causes of patulous Eustachian tube were as follows: weight loss in 14 patients, pregnancy in 2 patients and mixed connective tissue diseases in 2 patients. Fifteen patients were diagnosed with hearing loss including 6 patients with deterioration of hearing level in low frequencies. Regarding to the treatments, medication and nasal instillation of physiological saline were less effective than insufflation of the Lugol's solution or infusion of absorbable gelatin sponge solution into the pharyngeal orifice of the Eustachian tube. However the duration of effectiveness on the symptoms were short in the last 2 methods.<br>Four patients treated with conservative treatments described above were eventually underwent the insertion of a silicone plug in the patulous Eustachian tube. In three out of the four patients, their symptoms were remarkably reduced after this treatment, indicating insertion of the silicone plug was very effective for the patients with severe symptoms.
