THE HEAD, SCALP, CRANIUM, BRAIN, AND FACE 477 Here the operative field is surrounded by an area of anesthesia,and at several points along this surrounding zone the long needle isentered and passed down to the bone through the points indicatedby the heavy dots, injecting the solution as the needle is advanced. However, it is to be recommended, as a general rule, that allextensive operations upon the soft parts or underlying bone in theregion supplied by the fifth nerve be operated by injections of gangliongasseri, or its nerves at their foramina of exit; the injection of the gan-glion has the advantage that it anesthetizes the dura through its men-ingeal branches as well as the overlying bone and soft Fig. 148.—Surrounding a compound fracture of skull with zone of anesthesia. (From Braun.) As the occipital nerves are several in number, and reach the scalpat different points, they may be dealt with collectively. If a line ofanesthesia (solution No. 2, with 5 drops adrenalin to the ounce) isproduced, extending from ear to ear across the base of the mastoidprocesses, and carried well down to the deep tissues, it will block allbranches of the occipital nerves, as well as branches from the auricularismagnus, and result in an anesthetic area, as indicated in Fig. 149 (thewhite line shows the fine of infiltration), or the nerves may be dealtwith more or less individually in the following way: The occipitalis major and minor and the auricularis magnu
