Abstract

OBJECTIVE:

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.

STUDY DESIGN:

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.

RESULTS:

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.

CONCLUSIONS:

We hypothesize that ultrasound-guided IAN block may be feasible in humans using our technique.
