The wire loop of the snare should then be worked gradually inward over its surface until, if possible, the pedicle of the polypus is encircled. The wire loop should then be tightened and made to cut through the polypus. If the operator has not succeeded at the first attempt in removing the whole of the polypus, this manoeuvre may be repeated until the desired result has been Fig. 80. accomplished. Bleeding may be checked at any stage of the operation by means of a tampon of absorbent cotton, and by afterward cauterizing the stump of the polypus with nitrate of silver fused on the end of a probe. For the removal of polypi Blake's snare (Fig. 79) is perhaps the most convenient instrument, but Sexton's, Gruber's, or Wild's snare is almost equally efficient. Recently the author has had made an aural polypus-snare consisting of a needle and canula, so constructed as to be used as an auxiliary "tip" with Sexton's combination forceps, so that when the eye of the needle is threaded with wire the loop so formed can be enlarged or diminished at the pleasure of the operator--a matter of some importance in guiding it along the auditory canal over a large polypus. Other advantages of this instrument are the quickness ami ease with which it can be manipulated, and the fact that when the wire is in position around a small polypus the canula can be thrust forward over the wire loop, and thus prevent the wire slipping over the polypus instead of excising it (Fig. 81). What is the pathology of aural polypi? Aural polypi may be divided into four classes. About 50 per cent. of all aural polypi are granulation-tumor...
