A text-book on diseases of the ear, nose and throat . sed through the naris,endeavoring to carry one on each side of the growth and to bring themout of the mouth. Into the ends that are brought out of the mouththe ends of a piece of No. 20 platinum wire about three feet in lengthare introduced and pushed on until they come out of the nostril. Athread is attached to the wire loop to enable the operator to draw itbackward in case of failure in the first attempt to place it about thetumor. The catheters with the wires i)rotruding from the nostril are nowdrawn upon, and the loop, passing back into the mouth, is carried withthe finger, or with the aid of a postnasal snare applicator (Fig. 169), upabout the tumor, where it is drawn firmly into place. The cathetersare then withdrawn and the wires intrusted to an assistant, who holdsthem carefully to iDrevent their becoming crossed in the naris. The endsof the wire are then slipped through the tubes of the galvano-cauteryecraseur and fastened to the ratchet on the handle. It is desirable to have. 452 DISEASES OF THE NOSE AND NASOPHARYNX. the distal ends of this electrode separated about a quarter of an inch, oreven more, so that it may be the more readily passed upon either side ofthe tumor. As the instrument is pushed into the nose the ratchet isturned to tighten the loop, which is drawn tight upon the pedicle of thetumor before the electric current is turned on. As it is very difficult to adjust the platinum loop i)roperly with thepatient under ether or chloroform, it is better to rely on the anaestheticeffect of cocaine 5 but its benumbing quality in this locality is not suffi-cient to prevent considerable pain during the burning off of the growth ;therefore, when everything is in readiness, the iDatient should be told tobear the burning as long as possible, and that the current will be stoppedas soon as he requests it. The current is then turned on and the ratchettightened at the same time. The patient will endure the p
