Which of the following is NOT listed as a complication of a V2 maxillary nerve block?

• A. Hematoma from puncture of the maxillary artery
• B. Penetration of the nasal cavity
• C. Penetration of the orbit
• D. The block is therefore rarely done

Answer: (D)

When assessing complications of a V2 maxillary nerve block, think about the anatomy the needle passes near. The infrazygomatic/pterygopalatine region sits close to the maxillary artery and pterygoid venous plexus, so accidental puncture can cause a hematoma. The nasal cavity and maxillary sinus are adjacent to the injection path, so misplacement can breach nasal structures. The orbit lies nearby via the inferior orbital fissure, so improper needle direction can lead to orbital penetration.

The statement about the block being rarely done is not a complication at all; it’s a note on how often the procedure is performed, not a adverse outcome of the injection. Therefore this option is not a listed complication, which is why it’s the correct choice.
