La pathologie et le traitement chirurgical des tumeurs . du pharynx.Pendant les conditions humides, les tumeurs absorbent l'humidité, la houle et la production d'obstruction que pendant les temps secs. Si elles sont nombreuses et grandes, elles di.stend le nez, et lorsqu'elles sont situées dans le bulingat frontal des sinus l'angle intérieur de l'orbite a lieu, comme celui produit des byhydrops ou par empyema de cette cavité. Un myxome nasal apparaît comme une masse translucide et gelée qui se moule à la cavité du nez. Elle est couverte.par la mucomembrane pavée d'épithélium columnaire ou stratifié.

The pathology and surgical treatment of tumors . of the pharynx.During moist weather the tumors absorb moisture, swell, and producemore obstruction than during dry weather. If numerous and large, they di.stend the nose, and when located in the frontal sinus bulgingat the inner angle of the orbit takes place, like that produced byhydrops or by empyema of this cavity. A nasal myxoma appears as a jelly-like, translucent mass whichmoulds itself to the cavity of the nose. It is covered.by mucousmembrane paved with columnar or stratified epithelium. Under themicroscope the tumor-tissue appears like very oedematous connectivetissue. The great mass of the tumor is composed of myxomatoustissue in the meshes of the reticulum of connective tissue and paren-chyma-cells (Fig. 289). The blood-ves.sels traversing the connective-tissue .stroma are usually quite large with very thin vessel-walls. Nasalmyxoma occurs most frequently in persons from the age of puberty tothat of fifty years. The removal of nasal myxomata is by no means an easy operation..

In cases in which a permanent cure followedthese procedures, usually a part of the turbinated bone to which the Fig. 289.—Myxoma of nose (Surgical Clinic, Rush Medical College, Chicago) : a, delicate connective-tissuestroma; i5, granular amorphous myxomatous material, non-staining; c, nuclei; <;, blood-vessels. tumor was attached was removed with the tumor. Konigs operationshould be resorted to if snaring and avulsion have not resulted satis-factorily. This operation consists in cutting through the ala of thenose on the side of the septum from within outward as far as the bonyframe
