The term polypus includes two forms of diseased growths. The first is extremely rare; it is nearly colorless, fleshy in appearance, and attached by a stalk to the middle of the external ear. Its surface is smooth; it is devoid of sensibility, and often unattended by any discharge. This form of polypus is the result of Inflammatory changes which usually subside before the growth appears.

The second form is not uncommon; it is the immediate consequence of inflammation and is invariably attended by a discharge. By some it is called the bleeding polypus or haematoid; it varies in size and may become sufficiently large to appear at the outer opening of the ear. Its surface is rough and glistening, and deep red in color. It is almost gelatinous in substance, is exceedingly sensitive, and bleeds easily. This form of growth has usually a deeper origin near the drum of the ear, and is more commonly a consequence of otitis, media or interna.

Symptoms

Constitutional symptoms are present in certain cases of polypus; in others none appear. If they are large growths and attended with pain, the animal by his manner indicates the seat of the disease as in canker. The local symptoms are profuse, offensive discharges, tinged with blood.

If a dog has experienced an attack of otitis, media or interna, and four or Ave weeks later,notwithstanding treatment,a discharge persists, purulent, bloody, and of very offensive odor, it is strongly indicative of the existence of a polypus of the second form. An examination with a specnlum renders a diagnosis easy, even when the polypus is forming and very small.

Treatment

Efforts should be made to improve the general health, and relieve the local condition which first induced the formation of the polypus. Perfect cleanliness by injections, the use of powdered alum, or boracic acid dropped into the ear, may cause the growth to waste and become detached. If this treatment is unsuccessful a skilled aurist should be consulted.
