THERE is no satisfactory classification of chronic nasal and sinus diseases. In most instances these conditions exist together, the nose being equally involved with the sinuses; hence a separate classification for nasal and for sinus diseases, respectively, is redundant. Attempts to label these diseases on the criteria of tissue changes, whether gross or microscopic, are difficult, because degenerative changes, such as hyperplasia, atrophy, cyst formation, suppuration and fibrosis, often exist together. Classification based solely on symptoms is similarly difficult because here, too, a symptom is often common to more than one condition.
The purpose of a classification is to identify a disease categorically so that it will be easily recognized as such by other practitioners. By combining a pathological condition which is more or less constant with a clinical term describing the dominant symptom presented by the patient, the following classification has been formulated.
Atrophic rhinitis (sinusitis)
