Anesthesia · single question
An injection is placed into the incisive foramen (nasopalatine block). Which structure is NOT anesthetized by this injection?
Show answer and explanation
Correct answer: A. Greater palatine nerve distribution
- A. The GREATER PALATINE nerve is anesthetized by the greater palatine block (at the greater palatine foramen), NOT the nasopalatine/incisive block. The nasopalatine block covers only the anterior hard palate (anterior to canines).
- B. The pterygopalatine ganglion is associated with this nerve pathway.
- C. The nasopalatine nerve supplies the anterior nasal septum; the incisive foramen block can anesthetize this area.
- D. The sphenopalatine ganglion connects with the nasopalatine pathway and may be partially affected.
