OBJECTIVE
To investigate the degree to which transnasal eustachian tube (ET) dilation balloon catheters are able to be passed through the ET in a cadaver model.
PATIENTS AND INTERVENTIONS
A cadaveric study of 8 cadaver heads (16 ears), which underwent transnasal ET insertion with a 3 × 20-mm balloon catheter with transtympanic endoscopic visualization and grading.
RESULTS
Catheter tip incursion into the protympanum or mesotympanum occurred in all ears. Radiological validation was obtained with correlation to published ET length data.
CONCLUSION
Middle ear incursion of balloon catheter tips can be demonstrated in a cadaver model and highlights the ongoing need for both caution in novel surgical techniques and evolution in device design.
目的
在尸体模型中研究经鼻咽鼓管（ET）扩张球囊导管通过 ET 的程度。
患者和干预措施
对 8 个头骨（16 只耳朵）进行了尸体研究，这些头骨通过经咽鼓管内镜可视化和分级进行了经鼻 ET 插入，并使用 3×20mm 的球囊导管。
结果
所有耳朵的导管尖端都进入了前鼓室或中鼓室。通过与已发表的 ET 长度数据的相关性获得了放射学验证。
结论
在尸体模型中可以证明球囊导管尖端进入中耳，这突出了在新的手术技术中需要谨慎，并需要在器械设计方面不断发展。
