Ultrasound-guided maxillary nerve block: an anatomical study using the suprazygomatic approach.

CONCLUSIONS: We showed that 5 mL of injectate far exceeds the capacity of the PPF, leading to drug spread outside of the PPF. Moreover, we found that 1 mL of injectate largely covered the nerve, suggesting a more efficacious and safer block procedure. This finding will need confirmation in future clinical studies.
