Oral Surgery, Oral Medicine, and Oral Pathology 1979, 47 (2): 109-13
The second division of the trigeminal nerve can be easily blocked by the intraoral route. The technique presented involves entering the greater palatine foramen, traversing the pterygopalatine canal with a needle, and depositing the local anesthetic solution into the superior aspect of the pterygopalatine fossa, where the trunk of the second division lies after the nerve exits the foramen rotundum. The indications, contraindications, technique, and anatomic considerations are presented. This is followed by a discussion of the possible complications as well as their prevention and remedy should they occur. While this is not a new technique, it as been a forgotten one.
