    entrance situated beneath the lower angle of the zygoma (Fig. 96). A wheal is made at this point and the needle inserted below the infraorbital foramen and pushed as far as the bone of the nose. At this point 5 cc of a 2 per cent novocaine-suprarenin solution are injected. The needle is now partially withdrawn and passed toward the posterior surface of the upper jaw, injecting at this point 5 cc of a 2 per cent or 10 cc of a 1 per cent novocaine-suprarenin solution. The introduction of the needle to the foramen rotundum is not necessary. The injection, as is frequently done by dentists, can be carried out from within the mouth (see page 263). The customary injection of the anterior surface of the upper jaw is not sufficient for complete anesthesia of an acutely inflamed sensitive mucosa of the antrum of Highmore, as can be readily under¬ stood from the innervation of the upper jaw.

The Resection of the Upper Jaw.—A resection of both halves of the upper jaw, including the hard palate, was performed by Matas in 1900 under local anesthesia. Fie proceeded as follows: A long needle was passed through the sphenomaxillary fissure to the sphenopalatine fossa of both sides and injection of 3 cc of a 0.2 per cent cocaine solution with 1.5 cc of a 1 per cent cocaine solution made in order to block the infra¬ orbital nerves. In about five minutes the skin of the cheek, upper lip and the alee of the nose became anesthetic. The septum and hard palate were infiltrated direct with Schleich’s solution. The operation was carried out, the only painful part being the cutting of the vomer. This operation was not again attempted; in fact, before the introduction of
