PRACTICAL APPLICATION OF LOCAL ANAESTHESIA 133 For more extensive operations itCleft Palate, Hare Lip, is usually necessary to anaestliet-Amputation ot the ize the whole division of the fifth Alviolar Process, nerve, supplying the region in Resection of Jaws question. For cleft palate we an- aesthetize the second division \\itlithe sphenomaxillary injection. Injections into the incisive,posterior and accessory palatine foramina are also amputation of the superior alviolar process, the zygomatic,infra-orl)ital, incisor and post palatine injections are sufficientFor amputations of the lower alviolar process, use the pterygo-mandibular injection, and in both cases combine the conductivewith the infiltration method. For larger operations, as ampu-tations of the upper or lower jaw, Haertel* (clinic of theUniversity of Berlin) recommends the Gan
