If there is another polyp in the ear it will be revealed after theremoval of the first, and is to be treated in the same way. As it liesdeeper, it will require more care and skill to snare the inner one. Moreor less hemorrhage follows the removal of aural polypi. This is veryslight—a few drops—in the removal of small ones.

After the point of attachment of the polyp has been carefully touched with chromic acid,some antiseptic powder, preferably that composed of boric acid and calen-dula (page 182), should be blown into the fundus of the canal, and theear let alone for twenty-four hours. The next day the ear should beexamined, and, if the powder is found to be dry in the fundus of thecanal, it should be let alone until the next day, or unti
