=Treatment.=—The treatment should be general and local and should be determined by the causes and conditions present. This disease is usually an acute infection and like other acute infections, the usual systemic treatment should be applied. The local treatment consists of thorough cleansing of the nasopharynx (by irrigation if the patient can permit) and the frequent (or occasional as required) use of some gargle until the inflammation has subsided. Any cleansing nonirritative solution may be used for a gargle. Equal parts of peroxide, alcohol and glycerine, a tablespoonful to a half glass of very warm water or ten to fifteen drops of phenol-glycerine to a half glass of warm water will make a good cleansing gargle. The osteopathic treatment consists of corrective work to the cervical, upper thoracic and hyoid and thorough relaxation of the submaxillary musculature to obtain good venous and lymphatic drainage. If sufficient care be taken to avoid trauma, digital stretching of the soft palate and pharyngeal muscles by the use of the finger internally, is very efficacious. Chronic Pharyngitis Chronic pharyngitis may be hypertrophic, atrophic or granular. In hypertrophic pharyngitis the pathologic changes have passed beyond the stage of hyperemia and there is always hypertrophy or hyperplasia, usually the latter, of the pharyngeal membranes. These changes in most cases, have extended to and involved all of the nasopharyngeal membranes. Chronic granular pharyngitis, or so-called clergyman’s sore throat, has a similar pathology to that described above, but with swollen and inflamed lymph follicles. This condition seems to be a result of excessive use of the voice. Chronic atrophic pharyngitis has a similar etiology and the diagnostic signs are also similar to atrophic nasopharyngitis with which it is usually associated. =Etiology.=—The causative factors are similar or the same as those of nasopharyngitis. Lesions of the cervical and upper thoracic and chronic focal infections such as tonsillitis, sinuitis, etc. are the common causes. =Treatment.=—The nature of the treatment should be determined by the causes found. The nature of the pathology requires long continued treatment and careful attention to all causes. Thorough osteopathic corrective work, the removal of all sources of focal infection, proper attention to any gastro-intestinal perversions which may be causing auto-intoxication and thorough cleanliness of the parts by gargling with some cleansing, non-irritating solution and by irrigation.
