Outcomes included the ability to perform a Valsalva maneuver, audiometry results, tympanometry results, ETD Questionnaire (ETDQ-7) score, and TM status. <\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p> Eighteen patients (18 ears) were included in this study. There were statistically and clinically significant improvements in the mean ETDQ-7 score at 6\u2009months postoperatively (change in mean score of 16.7\u2009\u00b1\u20093.6, P\u2009&lt;\u20090.001) and at 30\u2009months postoperatively (change in mean score of 18.9\u2009\u00b1\u20092.9, P\u2009&lt;\u20090.001). Type A tympanogram was obtained in 27.8% of patients (5\/18) at 6\u2009months postoperatively, and in 77.7% at 30\u2009months postoperatively. A Valsalva maneuver was possible in 72.2% of patients at 6\u2009months postoperatively and in 88.9% of patients at 30\u2009months postoperatively. In addition, the ears of 13 patients (72.2%) showed both normal tympanograms and TM at 30\u2009months postoperatively. Interestingly, 38.5% of patients (5\/13) exhibited complete sclerosis of the pars tensa. None of the patients experienced severe MWA-related complications during follow-up. <\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p> MWA eustachian tuboplasty is a feasible alternative to conventional tuboplasty, and can improve subjective and objective outcomes in patients with ETD for up to 30\u2009months following treatment. In addition, this study showed that the extent of sclerotic plaque increased over time, whereas the extents of atrophy and tensa retraction decreased following tuboplasty in most patients.
