The result of such an injection is seen inthe anesthetic area, as indicated in Fig. 58 (ten or fifteen minutes delayis necessary for the full effect to be shown). The anesthesia of thesuperficial parts is complete almost to the midline of the neck; herethe nerves from the opposite side lap over; it will consequently be.

The depth of the anesthesia will depend upon the depth of theinjection; however, in making the injection into the deep parts,care should be taken not to pass the needle too far forward underthe sternomastoid, for fear of injuring the deep vessels in thisposition. Some of the deep branches will be found, upon deep dissections,to have escaped the effect of the injection; these deep branches arefor the anterior parts, communicating branches to the pneumogastric,hypoglossal, and sympathetic nerves, communicans hypoglossi andmuscular branches; posteri
