atrophic rhinitis
atrophic rhinitis n
1) a chronic disease of swine that is characterized by purulent inflammation of the nasal mucosa, atrophy of the nasal conchae, and abnormal swelling and distortion of the face

* * *

a chronic form of rhinitis that is nonallergic and noninfectious, marked by wasting of the mucous membrane and the glands. In the early stages there are small dry areas with crusting, either with viscid secretions or without secretions (see r. sicca). In later stages the nasal passages become enlarged and have a foul smell, progressing to ozena (q.v.). It is sometimes the result of trauma, and vascular damage by radiation therapy, environmental irritants, and disease has also been implicated.
