Balloon dilation Eustachian tuboplasty was performed under local anesthesia in a tertiary referral center, using the EVB. Systematic literature review was used for comparison, using Medline via \u201cPubMed\u201d, \u201cEmbase\u201d, and \u201cWeb of Science\u201d.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Eight OETD candidates (12 ears) were enrolled; 5 males and 3 females. Average age was 48 (range \u221223 to 63) years. The most common presenting symptom was aural fullness (9\/12), followed by ear pressure (7\/12), hearing loss (5\/12) and tinnitus (4\/12). Otoscopically, tympanic membrane retraction was evident in 10\/12 ears, the majority of which was class II\u2014Sade classification. Pre-operative tympanogram was type B and C in 7 and 5 ears, respectively. All BDETs were performed without complications. Post-operative tympanometry was A in 8\/12 ears. Post-operatively, Eustachian Tube Dysfunction Questionnaire-7 results reduced to within normal limits (average score \u22643) in 11\/12 ears (<jats:italic>p<\/jats:italic>\u2009=\u20090.0014). The systematic literature review included 6 papers (193 patients, 262 ETs) with comparable results, most also with little adverse effects.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>BDET using an EVB is a safe and effective option for OETD. It is well tolerated under local anesthesia in properly selected individuals.
