The diagnosis of sessile polypus requires a careful use of all the aids of rhinoscopy. They can be distinguished from hyperplasia of the mucous membrane by their lobulated form, and from the fact that the probe can move them slightly from their base. They can be distinguished from adenoid growths at the root of the pharynx by the fact that they remain unmoved during the act of swallowing. The disease is not apt to recur if the treatment is thoroughly carried out. The treatment of soft polypus consists in their removal. All observers are now agreed on this point. Injection by astringents and acetic acid--a process that at one time held out much promise--has been generally abandoned. In removal of the polypus one of two methods may be resorted to: that by avulsion, and that by the use of the snare. Avulsion is effected by forceps adapted for this special use. With such an instrument the polyps can readily be seized and removed. The rule that nothing should be seized which is not seen is subject to no exception. In no other way can the operator be secure against accidents. Incautious operators have frequently torn away strips of mucous membrane or portions of the turbinated bones in their crude attempts to remove these growths. Severe hemorrhage and death through violent lacerations of the ethmoid bone near the cribriform plate, and subsequent extension of the inflammation thereby excited to the membranes of the brain, have been known to follow these crude surgical procedures.
