Assess the feasibility of the use of a life-size model for ESS to perform balloon catheter dilatation of the paranasal sinus ostia.
Four validated sinus models were enrolled in this study. One experienced endoscopic surgeon performed all the dilatations of the paranasal sinus ostia. We used the Relieva Sinus Balloon Catheter System (Acclarent, Inc, Menlo Park, CA), and its described technique for fluoroscopic guided sinuplasty.
Twenty-four ostia were available. All sinuses were successfully catheterized and dilated. The total fluoroscopic time was 18 minutes and 8 seconds (mean, 45.3 seconds per sinus) and the total procedure time was 50 minutes and 56 seconds (mean, 2 minutes and 7 seconds per sinus).
It was feasible to perform a successful dilatation of the 24 available sinus ostia of the models: 8 maxillary, frontal and sphenoid. No major technical difficulties were encountered.
This model could help surgeons in the training of sinus ostia balloon dilatation.
评估使用真人大小模型进行内镜鼻窦手术（ESS）以对鼻窦开口进行球囊导管扩张的可行性。
本研究纳入了四个经过验证的鼻窦模型。由一名经验丰富的内镜外科医生对所有鼻窦开口进行扩张。我们使用了Relieva鼻窦球囊导管系统（Acclarent公司，加利福尼亚州门洛帕克）及其所述的荧光透视引导下鼻窦成形术技术。
共有24个开口可供操作。所有鼻窦均成功插管并扩张。荧光透视总时间为18分08秒（平均每个鼻窦45.3秒），总手术时间为50分56秒（平均每个鼻窦2分07秒）。
对模型中24个可用鼻窦开口（8个上颌窦、额窦和蝶窦）进行成功扩张是可行的。未遇到重大技术困难。
该模型有助于外科医生进行鼻窦开口球囊扩张的培训。
