[Rhinitis in old age].

The chronic rhinitis is a frequent problem with age. In the nose, normal physiologic changes of aging include loss of nasal tip support, atrophy of mucus-producing mucosal glands, and decreased olfaction. The fragmentation and weakening of the cartilage of the septum also causes airflow changes contributing to nasal stuffiness. These changes contribute to geriatric rhinitis, the symptoms of which are often attributed by the older patient to "allergies" or "sinus trouble". An understanding of these anatomic changes, linked with a thorough history and physical examination, allows the physician to properly manage geriatric rhinitis. Earnest causes like tumors or mycosis must be excluded. The treatment depends on the etiology of the rhinitis and also the symptoms of the patient. Therapy includes avoidance of all sorts of allergens (dust, fumes, sprays) and appropriate attention to minimizing home environmental and occupational exposures. Pharmacotherapy most often involves liquifying--not drying--nasal secretions with oral and topical preparations. Conservative surgical treatment is occasionally indicated.
