Histopathologic Relationship Between Ethmoid Sinus and Ipsilateral Middle Turbinate in Non-Polypose Chronic Sinusitis by FESS.

Chronic rhinosinusitis (CRS) is a common disease with significant effects on the quality of life. Infection was previously a common cause of rhino sinusitis, while nowadays its main cause is inflammation. Non-polyposis CRS patients who were resistant to medical treatment and underwent endoscopic sinus surgery in Ghaem and Imam Reza hospitals were studied from December 2008 to November 2009. There were 11 males and four females ranging in age from 14 to 57 years with the average age of 32.2. First, samples were taken from the ethmoid sinus and the ipsilateral middle turbinate. Then, histopathologic research on grade of inflammation, mucosal thickness, inflammatory cell count, metaplasia type, and hypersecretion was performed. Fifteen patients were studied. There were positive statistical correlations between inflammation grade, eosinophil counts and plasma cell counts in ethmoid and turbinate; but such a correlation was not found in lymphocyte and neutrophil in two sites. The prominent inflammatory cell in both areas was the same for 11 patients; whereas in other four cases, it was insignificantly different. Positive statistical correlation between the inflammation grades in two sites shows the coexistence of rhinitis and sinusitis; therefore, this proves the correct combination usage of rhinosinusitis. Prominent cells of the samples which were obtained from two places were similar for most patients, so this similarity is a sign of inflammatory process presence in both places. The prominent cells were mostly lymphocytes.There were more lymphocytes than eosinophils in non-allergic patients.
