Where the granula-tions are of larger size they should be removed by means of thecold wire snare (Fig. 112). the loop being carried upward tothe base and made to surround it, when by drawing the wireinto the tube of the snare the growth is cut off close to its at-tachment. I much prefer this method to evulsing the growthafter it has been surrounded by the loop. A practice which Ioften employ in these cases is removal of the tissue by meansof the sharp curette (Fig. 113). Instruments of various sizesare necessary in order to perform the operation effectively inthis manner. The curette is carried into the canal, passed. Fig. 112.—Removal of aural polyp with the snare.
