To report a novel technique in Balloon Dilation of Eustachian Tube (BDET) using an endovascular balloon (EVB), in a prospective cohort. The results are compared with reported outcomes using standard balloons.
Demographic information and clinical parameters were collected prospectively fora series of patients with obstructive eustachian tube dysfunction (OETD). 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 "PubMed", "Embase", and "Web of Science".
Eight OETD candidates (12 ears) were enrolled; 5 males and 3 females. Average age was 48 (range -23 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-Sade 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 ≤3) in 11/12 ears ( = 0.0014). The systematic literature review included 6 papers (193 patients, 262 ETs) with comparable results, most also with little adverse effects.
BDET using an EVB is a safe and effective option for OETD. It is well tolerated under local anesthesia in properly selected individuals. The reduced procedural cost may be an important factor in certain healthcare jurisdictions.
在一个前瞻性队列中报告一种使用血管内球囊（EVB）进行咽鼓管球囊扩张术（BDET）的新技术。将结果与使用标准球囊报告的结果进行比较。
前瞻性收集一系列咽鼓管阻塞性功能障碍（OETD）患者的人口统计学信息和临床参数。在一家三级转诊中心，使用EVB在局部麻醉下进行球囊扩张咽鼓管成形术。通过“PubMed”“Embase”和“Web of Science”使用Medline进行系统文献综述以作比较。
纳入了8名OETD患者（12只耳）；5名男性和3名女性。平均年龄为48岁（范围23至63岁）。最常见的症状是耳闷（9/12），其次是耳内压迫感（7/12）、听力损失（5/12）和耳鸣（4/12）。耳镜检查显示，10/12只耳有鼓膜内陷，其中大多数为II级 - 萨德分类。术前鼓室图分别在7只耳和5只耳中为B型和C型。所有BDET手术均无并发症。术后鼓室图在8/12只耳中为A型。术后，11/12只耳的咽鼓管功能障碍问卷 - 7结果降至正常范围内（平均得分≤3）（P = 0.0014）。系统文献综述纳入了6篇论文（193例患者，262只咽鼓管），结果相似，大多数也几乎没有不良反应。
使用EVB的BDET是治疗OETD的一种安全有效的选择。在适当选择的个体中，局部麻醉下耐受性良好。在某些医疗辖区，降低的手术成本可能是一个重要因素。
