Technic of Injection.—With the left index-finger the anteriorportion of the base of the ascending ramus is palpated, the patientsmouth being opened widely. Two very marked bony ridges are felthere, one anterior external, the external oblique line, and one pos-terior internal, the internal oblique line (Figs. 183, 184, 187, 188). THE HEAD, SCALP, CRANIUM, BRAIN, AND FACE ;2i Between these two lines at the root of the ascending ramus a shallow-bony grove is situated, which might be properly called the retro-malar fossa, into which the palpating finger-tip sinks (Figs. 183, 187,188, 189.) The mucous membrane is caved in over this fossa in some-what triangular shape; Braun, therefore, calls it the retromolar internal oblique line is fixed with the finger-nail, and theneedle inserted close to the nail into the mucosa near to, yet not im-mediately at, the edge of the bone (Figs. 183, 187, 188).. Fig. 187.—Position of syringe for injection at mandibular foramen: ix, External obliqueline; 2x, retromolar fossa; , internal oblique line; 4, mandibular foramen behind lingula;S, incorrect position of syringe, parallel to teeth. (After Fischer.) The syringe is pushed forward horizontally and posteriorly fromthe canine, on the opposite side along the internal surface of the man-dibular half to be anesthetized (Figs. 183, 184, 187, 188, 189). The needle should be introduced to a depth of not more thanfrom to 2 cm. under the mucosa, lest it advance too far beyond theforamen and the correct point for the disposition of the solution bemissed. 522 LOCAL ANESTHESIA The injecting solution is then deposited, beginning to inject soonafter insertio
