Figure 6

Sonoanatomy and ultrasound-guided injection technique for the auriculotemporal nerve: (a) the transducer position (yellow rectangle), (b) ultrasound imaging of the auriculotemporal nerve (white solid arrow), (c) introducing the needle in the posterior-to-anterior direction using the in-plane approach to target the auriculotemporal nerve, and (d) the power Doppler image of the superficial temporal artery. The empty white arrows denote the zygomatic arch. The yellow dashed arrow indicates the needle trajectory. MCFC: middle cheek fat compartment and LTCF: lateral temporal cheek fat. All the pictures were obtained from the face of the first author.
