Chronic rhinitis/sinusitis in the cat can be an annoying, persistent problem. Intermittent sneezing with mucopurulent discharge is the most common clinical sign. Response to medical management is variable, and some cats will spontaneously resolve. In the cat with unresponsive chronic rhinitis/sinusitis, surgical intervention may be attempted in order to relieve obstruction, afford better drainage, or obliterate the frontal sinuses with fat grafts. Success has been variable with all means of management. A guarded prognosis for complete cure should be given at the outset when managing a cat with chronic rhinitis/sinusitis.
