摘要
Background Not many imaging techniques have been reported in Eustachian tube imaging. Purpose To investigate the role of selective Eustachian tubography (SET) and Valsalva computed tomography (CT) in patients who underwent Eustachian tube balloon dilation (ETBD). Material and Methods Eligible patients were aged 18 years and older with chronic Eustachian tube dysfunction who had failed medical treatment. On the day of the procedure, Valsalva CT and SET were performed. Participants underwent fluoroscopic ETBD with a 6x20-mm balloon catheter. Clinical examinations to check for the ability to perform the Valsalva maneuver and ETDQ-7 score change were conducted at one week and then at one, two, and six months. Follow-up Valsalva CT was performed in the one-month follow-up. Results A total of 30 ears in 23 patients (16 right ears, 14 left ears; 10 women, 13 men) underwent ETBD from August 2018 to November 2019. Positive CT patency was higher in follow-up Valsalva CT than baseline Valsalva CT (40% and 23.3%, respectively) (P = 0.006). In SET, positive patency was observed in 13 of 25 ears. Response to balloon dilation was observed in 18 of 25 patients. Clinical success was achieved in 16 of 27 ears. Response to balloon dilation was the only significant predictor of clinical success (P = 0.012). Conclusion SET depicted the lumen of the Eustachian tube; thereby, it could be a potentially valuable tool in ETBD. Valsalva CT provides additional information about the cartilaginous portion of the Eustachian tube.
