 Saito describes a new approach to establish a complete anethesia of the maxillary nerve in order to alleviate the source of pain altogether in the operation of the maxillary sinus. Heretofore the procedure by which induction anethesia may be established within the pterygopalatine fossa required much practice and experience on the part of the surgeon and yet, resulted with a margin of uncertainty. The present method eliminates all of these troubles. With infiltration anesthesia the tissues on the anterior surface of the maxilla are anethesized even towards the maxillary tuberosity posteriorly and beneath the zygomatic arch superiorly. The usual incision in the canine fossa is carried further posteriorly towards the tuberosity. The infratratemporal surface of the maxilla is exposed: at the region where this surface and the anterior wall of the sinus cavity conjoin to form a raised area the periosteum is incised and separated to expose the pterygopalatine fossa. By use of a curved or an angled needle maxillary nerve may be reached with ease for a complete anesthesia.
