OBJECTIVE: Histologic changes have not been systematically assessed in chronic rhinosinusitis. Quantitative histochemical studies evaluated the extent of sinus disease and gland density in the middle turbinates. STUDY DESIGN AND SETTING: Sinus computed tomography scans of 34 patients with chronic rhinosinusitis were retrospectively graded 0 to IV according to the May classification. Middle turbinates from patients with chronic rhinosinusitis (n = 46) and normal patients (n = 7) were harvested during endoscopic sinus surgery. The areas of Alcian blue-stained glands were assessed in paraffin sections using a computer-assisted microscopy video system. RESULTS: Alcian blue-stained glands occupied 7.94% of normal mucosa. The staining in all grade III rhinosinusitis subjects was increased to 12.94% (P < 0.01). In contrast, grade IV pansinusitis was associated with nasal polyposis (6 of 6) with decreased gland area (3.04%, P < 0.01). When polyp patients were excluded from grade III rhinosinusitis, the Alcian blue-staining area was 17.68% (P < 0.01). CONCLUSIONS: Distinct polypoid and glandular histopathologic patterns are present in chronic rhinosinusitis.
