[Outcomes and correlation after functional endoscopic sinus surgery in patients with chronic rhinosinusitis]

To investigate the correlationship between the assessment of subjective and objective in patients with chronic(CRS) rhinosinusitis before and after FESS.

Seventy patients with CRS were objectively assessment of VAS and subjectively assessment including the Lund-Kennedy endoscopic scale and Lund-Mackay scale. All patients were followed up 1 year and repeated both the objective and subjective assessment. The correlationship among the different assessments were investigated and the scales of before and after FESS were compared.

There were positive correlation between the scale of VAS and Lund-Mackay(r = 0.866, P < 0.01), positive correlation between the scale of Lund-Kennedy and Lund-Mackay(r = 0.803, P < 0.01), and positive correlation between the scale of VAS and Lund-Kennedy (r = 0.912, P < 0.01) before the FESS. There were positive correlation between scale of VAS and Lund-Kennedy after 6 and 12 months of FESS with the r-value of 0.798 and 0.882 respectively. The scales of VAS including nasal obstruction, nasal discharge and head pain have positive correlation with the total scale of Lund-Kennedy with r-value of 0.691, 0.760 and 0.751 respectively. And the scales of VAS including hyposmia and general malaise have positive correlation with the total scale of Lund-Kennedy with r-value of 0.327, and 0.438 respectively. The scale of Lund-Mackay before has positive correlation with both the scale of Lund-Kennedy and VAS.

In patients with CRS, there were correlations among the scales of CT assessment, nasal endoscopic evaluation and VAS before FESS, and there were also correlations between the scales of CT assessment and nasal endoscopic evaluation after 6 and 12 months of FESS. It indicated that to evaluate the patients with CRS properly, the comprehensive assessment including subjective and CT and endoscopic scale should been applied in clinic.
