Fig. 183.—Front view of position of syringe in mandibular anesthesia: 1, Internaloblique line; 2, external oblique line; 3, insertion of needle about 1 cm. above masticatingsurface of molars. (After Fischer.) The foramen itself, in adults, is always situated above the alveolarridge and in a horizontal plane, about cm. from the anterior ridgeof the jaw (the external oblique line) (Figs. 182-184).. Fig. 1S4.—Position of needle in mandibular anesthesia: 1, External oblique line; 2,internal oblique line; 3, position of needle at superior margin of lingula; 4, most suitablelength of needle behind lingula (a further advancement would result in failure); 6, positionof needle, 1 cm. above level of masticating surfaces of molars; 7, lingula; 8, inferior dentalforamen. (After Fischer.) The two halves of the mandible, when viewed from in front, grad-ually diverge toward the angle, so that the inner surface of the anglewith the mandibular foramen is inclined posteriorly and pharyngeally, THE HEAD, SCALP, CRANIUM, BRAIN, AND FACE 519 and appears to be entirely covered by the internal oblique line. (SeeFigs. 181, 182, 185, 186). Position of Syringe.—The line of the body of the mandible is nothorizontally continuous in a straight line to the ascending ramus,but presents a lateral bulging at the angle, so that the internal surfaceof the ascending ramus is not parallel with the lingual sur
