Condition(s) studied

Investigational drug(s) / intervention(s)

Ultrasound-guided maxillary nerve block: Suprazygomatic approach, ultrasound-guided infrazygomatic window, maxillary nerve block for injection of 2 - 5 ml of contrast

Study summary

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.

Eligibility

Primary outcome measure(s)

• Spread of contrast to mandibular nerve branches — 0 hours (After performing the maxillary nerve block)
  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.
