The ease with which the large majority of normal tonsils can be displaced from their normal position, either by traction of the tonsil itself or by pressure on the anterior faucial pillar, is a matter of everyday observation to those performing operations on the tonsils. This dislocation of the tonsil is so important to the technic of all tonsillectomies that a firmly fixed tonsil makes any type of operation much more difficult. With this dislocation there must, of course, be some disturbance of the normal anatomic relations, and the study to be outlined in this paper was conceived with the idea of determining, if possible, just what this disturbance is. Is the region external to the dislocated tonsil filled in by an internal bulging of the superior constrictor muscle, or is there sufficient elasticity in the areolar tissues of the tonsillar fossa to permit the approximation of the faucial pillars
