The purpose of this study was to develop a methodological technique for the ultrasonographic visualization of the inferior alveolar nerve (IAN) using a novel hockey stick-shaped 8- to 15-MHz transducer in volunteers, followed by simulated IAN scanning and injection in cadavers.
In 20 volunteers, bilateral scans of the IAN nerve were performed with a systematic technique. We recorded times to scan each side and sonographic visibility of the IAN. In 3 cadavers, bilateral scans of the IAN were performed, followed by simulated injection with dye.
The IAN was visible in all 40 scans. Mean scanning times were 19.6 seconds (range: 4-54 seconds) for the left side and 30.5 seconds (range: 6-116 seconds) for the right side. In 5 cadaver injections, dye was correctly deposited onto the IAN with the ultrasound technique.
We hypothesize that ultrasound-guided IAN block may be feasible in humans using our technique.
本研究旨在开发一种使用新型 hockey stick 形 8-15MHz 换能器对志愿者下颌神经（IAN）进行超声可视化的方法技术，随后对尸体进行模拟 IAN 扫描和注射。
在 20 名志愿者中，采用系统技术对 IAN 神经进行双侧扫描。我们记录了扫描每侧的时间和 IAN 的超声可见度。在 3 具尸体中，对 IAN 进行双侧扫描，然后用染料进行模拟注射。
40 次扫描中均可观察到 IAN。左侧扫描的平均扫描时间为 19.6 秒（范围：4-54 秒），右侧为 30.5 秒（范围：6-116 秒）。在 5 例尸体注射中，超声技术可将染料正确沉积到 IAN 上。
我们假设使用我们的技术，超声引导下的 IAN 阻滞在人体中可能是可行的。
