What drives the inflammatory response in rhinosinusitis.

The dilemma of treating chronic sinusitis continues to confuse clinicians. When mucosal thickening does not respond to aggressive antibiotic therapy, other etiologies should be considered. Perhaps the most likely is the inflammatory response. In comparison with asthma, chronic sinusitis exhibits amazing similarities. Atopic dermatitis also exhibits similar inflammatory responses that lead to thickening of the skin in a manner not dissimilar to mucosal thickening. The interactions amid eosinophils, lymphocytes, leukotrienes, interleukins, and epithelial cells serve as a reminder that there is one immune response and similarities exist in the pathophysiology of these conditions.
