Chapter 23 – Distal Trigeminal Block


The distal trigeminal block can be used for the diagnosis of facial neuralgia; more frequently, however, it is utilized for superficial surgical procedures that require more than simple infiltration for anesthesia.

Patient Selection.

Pharmacologic Choice.

Owing to the small volumes of local anesthetic necessary for this block, almost any local anesthetic agent may be chosen.
