There are many cases in which the membranes of the nose have lost their tone due to various irritants or from deficient nutrition to the parts. These are cases of a wholly different type from that of the well known necrotic diseases such as atrophic rhinitis and syphilis. Hay fever is a result of such a cause. The treatment in such cases consists of removing any local causes or osteopathic lesions and then normalizing the resistance of the membranes by the methods described under the treatment for hay fever. The treatment for those cases of epistaxis due to constitutional disease depends wholly upon the causative factors and the proper treatment of these. Any local treatment in such cases will be expected to produce only temporary results. Diseases of the Nasopharynx The nasopharynx may be the location of acute or chronic inflammations, neoplasms, malignant or nonmalignant, processes of atrophy or hypertrophy, adhesions, etc. It is important to remember that the nasopharynx admits the Eustachian tubes and supports four superficially located ganglia of the fifth nerve. =Acute Nasopharyngitis.=—Acute inflammatory processes of this region may result from rhinitis, infections of the lower pharynx, focal infections of these parts or from direct involvement of its own structures. The symptoms are post nasal tenderness and mucus dropping. Some patients experience the sensation of a foreign body in that location. The thick, adherent collections of mucus are difficult to dislodge and sometimes are so persistent that they cause nausea. There is usually occlusion of the Eustachian tubes, resulting in partial deafness, tinnitus and often dizziness. =The Treatment= consists of thorough cleanliness by irrigation and osteopathic corrective work to the cervical region. It is also essential to keep the anterior neck structures particularly those of the submaxillary region, thoroughly relaxed to maintain efficient drainage. Chronic Nasopharyngitis This is one of most common diseases of the nasopharyngeal tract, causative of many complications and yet perhaps the least recognized in proportion to its significance. The frequent occurrence of adhesions of the pharyngeal fossæ, hypertrophied membranes, enlarged spongy extensions of the inferior and middle turbinates (the posterior turbinate bodies) occlusion of the orifice of the Eustachian tubes and chronic, excessive secretion of thick mucus all show that this disease has either gone unrecognized or at least has not received proper treatment.
