It is far easier to make an accurate injection in THE HEAD, SCALP, CRANIUM, BRAIN, AND FACE 515 contact with the parent trunk (third division of the fifth) at the baseof the skull than to accurately inject this nerve here, both for purposesof anesthetization as well as alcoholization in cases of neuralgia. In the one case the end may be obtained by using a large amountof anesthetic fluid, but this as it diffuses in all directions producesa very unpleasant sense of paralysis of the throat, which is quite terri-fying to some patients, particularly if it occurs during the progressof an operation. An alcohol injection, if too liberally made at this point, may resultin a more or less prolonged trismus through the action of the alco-hol upon the masticatory muscles.

The long arrow indi-cates the direction in which the needle should be pushed forward over the lingula. Thedotted circle indicates the area of injection. (Fischer.) The inferior dental or oblique mandibular foramen in the internalsurface of the ascending ramus permits the passage of the inferiordental nerve, which, with the inferior dental artery, passes forwardin the dental canal of the mandible as far as the mental foramen, whereit divides into two terminal branches, incisor and mental. For thetechnic of injection in the oblique foramen the relationship of the bodyof the jaw to the ascending ramus and that of the muscles to
