It is positioned anterior and inferior to the ear, seated superficially on the ramus of the mandible, wrapping posteriorly and deeply to it. It extends from the lower border of the mandible and up to the zygomatic arch. It is enclosed within the split investing layer of deep cervical fascia.

The incision for the electrode is carried down through the platysma muscle revealing the supraclavicular fat pad, which is bluntly dissected down to the investing layer of deep cervical fascia. Immediately deep to this fascia lies the phrenic nerve running in a lateral to medial direction and superficial to the anterior scalene muscle. Positive identification of the phrenic nerve is achieved with a disposable nerve stimulator revealing diaphragm movement.
