A largecrypt or lacuna in the midst of this bursa often ends in a dilatedextremity which sometimes becomes distended by accumulation ofsecretion owing to obstruction of its outlet, thus forming a cyst of.

(Grilnwald.) considerable dimensions which occasionally undergoes has been particularly studied by Tornwaldt and from him is knownas Tornwaldts disease, or cyst of the pharyngeal bursa. Thepharyngeal tonsil, or adenoid vegetations, becomes of interest andimportance in its enlarged condition from the obstruction it offersto nasal respiration, from disturbance it may excite in the ear bypressure in the region of the Eustachian tube or orifice, and from 2 24 DISEASES OF THE NOSE AND THROAT. the causative relation it bears to various other disorders, reflex de-rangements as well as infectious diseases (Fig. 80). Adenoids may be met with very early in life, if they are notactually congenital. They are always an impediment to health andin a nursing infant may be a serious obstacle to nutrition. They areseldom seen in adults, although several marked examples in veryold subjects have been recorded. Remnants of
