Although the maxillary nerve block is an important procedure in the operation of the maxillary sinus, it is not commonly used because of its complexity and uncertainty. The author developed a new, simple and certain technique of the maxillary nerve block Sixty-seven skulls were examined for this study. The principle of the new technique is as follow: With infiltration anesthesia the tissue on the anterior surface of the maxilla is anesthetized.The usual skin incision in the canine fossa is made. This in extended laterally toward the tuberosity and the infratemporal surface of the maxilla is exposed at the area where this surface and the antherior wall of the si- nus conjoin to form a crest.The periosteum is incised and separated to expose the pterygopalatine fossa. Using a curved or an angled needle, the maxillary nerve is easily anesthetized without any danger.
