To assess the feasibility, safety, and efficacy of transtympanic balloon catheter dilatation of the Eustachian tube (ET) in a cadaver model.
A cadaveric study of 10 cadaver heads, which underwent unilateral transtympanic dilatation of the ET with a 3 × 20 mm balloon catheter with full endoscopic guidance and visualization.
Procedural safety was demonstrated, with no damage to any essential structures found. Feasibility of the procedure was demonstrated in all cadavers with 100% success rate, despite a small number of encountered difficulties. Statistically significant efficacy was also demonstrated in both radiologic and manometric data.
With full endoscopic visualization, the transtympanic approach to balloon catheter dilatation of the ET seems to be a feasible and safe procedure in the cadaver model.
在尸体模型中评估经鼓膜气囊导管扩张咽鼓管（ET）的可行性、安全性和有效性。
对10个尸头进行尸体研究，在完全内镜引导和可视化下，使用3×20毫米气囊导管对ET进行单侧经鼓膜扩张。
证明了操作安全性，未发现对任何重要结构造成损伤。尽管遇到了一些小困难，但在所有尸体中均证明了该操作的可行性，成功率达100%。在放射学和测压数据方面也显示出统计学上的显著有效性。
在完全内镜可视化的情况下，经鼓膜途径进行ET气囊导管扩张在尸体模型中似乎是一种可行且安全的操作。
