Ultrasound provides direct visualization and imaging of various soft tissues without radiation exposure. Thus, it is a very appealing modality in neck injections, with the magnitude of critical soft-tissue structures compacted in a very vascular area. Moreover, ultrasound imaging allows real-time needle advancement and monitoring the spread of injectate, which improves the accuracy of the block and minimizes the risk of intravascular injection. This chapter reviews the feasibility and safety of the ultrasound-guided approach. It also provides a new insight into the technique and why some practitioners prefer an “extraforaminal” nerve root approach rather than the traditional “transforaminal” epidural approach.
