About this trial
Ultrasound-guided maxillary nerve block is mandatory for perioperative pain management of surgeries involving the middle third of the face. The suprazygomatic approach to the maxillary nerve has proven to be the safest and most effective. The volume used for maxillary nerve block remains a matter of debate; and this study aims to compare and study the dispersion of 2 - 5ml injected into the ptergopalatine fossa, and to know the reach of the mandibular nerve with this block.

Trial outcomes
Primary outcomes
1
Spread of contrast to mandibular nerve branches
To analyze the spread of 2 and 5 ml of injected contrast to branches of the mandibular nerve after suprazygomatic ultrasound-guided single injection into the pterigopalatina fossa.
Time frame
0 hours (After performing the maxillary nerve block)Secondary outcomes
1
Spread of contrast to other locations
To analyze the spread of 2 and 5 ml of injected contrast to other locations after suprazygomatic ultrasound-guided single injection into the pterigopalatina fossa. Compare different volumes (2 and 5ml) of contrast injected into the pterygopalatine fossa to investigate the location of its dispersion away from the maxillary nerve.
