Extraction is indicated only in the case of those polypi whoseorigin in the external meatus has been ascertained without doubt. 536 OPERATIVE TREATMENT OF POLYPI. It is much surer and quicker than the other methods of operation bywhich the polypus is cut off or ligatured. In the latter case thedestruction of the remaining fibrous roots requires a space of severalweeks or months, while by extraction the root is removed with thegrowth, and cure follows after a few days. Moreover, after extrac-tion recurrences are not so often observed as after excision of thepolypus with subsequent cauterization of the root. Before a polypus is removed from the ear the meatus should becleaned by syringing and filled with a 10 per cent, solution of cocaineby which the operation is made nearly painless. Extraction of a polypus of the meatus is best effected with Wildessnare (Fig. 280), it being pushed over the polypus near the root, and

This procedure is to be preferred to extraction by dressing-forceps, as with the latter the polypus is easily crushed, and only fragments of it are removed. In the case of polypi soft throughout, extraction with the snare is seldom complete, as the soft tissue is easily cut through. b. Ligature.—When a fibrous polypus is so closely connected with the osseous wall that considerable resistance is shown on strong traction, it is proper to use Wildes snare to constrict the polypus, the instrument after its loop is tightened being turned on its long axis till a greater resistance is felt. Then the wire fastened to the cross-bar is cut through with scissors, and the instrument removed from the ear. By the twisted wire loop left in the ear the passage of blood to the polypus is stopped, a, Root; b, Place of thereby causing its rapid mortificatio
