Chronic rhinophar-yngitis accompanying the latter affection is apt to end in atrophy of themucous membrane of the nasoi)harynx. The surface of the mucosa inthese cases of chronic rhinopharyngitis is usually reddened and vascular,but may in some cases be even paler than normal. The mucous mem-brane is thickened and boggy in appearance. Microscopically, the epi-thelium shows an extension uj)ward of the pavement epithelium of theoropharynx to a greater or less degree ; in other places the epithelialsurface is lost, or the ciliated cells are replaced by layers of cuboid children the ciliated epithelium normally extends downward on the Fig. 101.
