Disturbances now commonly attributed to infected tonsils may be grouped under three heads, as follows:
1. Acute and chronic tonsillitis (symptoms in the tonsils themselves).
2. Diseases of the contiguous mucous membrane, that is, pharynx, larynx, trachea, bronchi, Eustachian tube and middle ear, arising from the pouring out of infected secretion from the tonsillar crypts.
3. Remote secondary infections, such as rheumatic arthritis, pericarditis, etc.
To these three groups there should be added a fourth not commonly attributed to infected tonsils, but which, it is hoped, this paper will demonstrate should be so ascribed, namely:
4. Local infections involving structures in the neck contiguous to the tonsil, giving rise to symptoms in this region, presumably, through involvement of nerves, often, by direct irritation or inflammation, but, sometimes, through reflex involvement, resulting in neuralgias and functional disturbances.
1. The first group was, until a comparatively recent period, the only one recognized.
