Objective Assessment of Nasal Function Changes after Revision Endoscopic Sinus Surgery in Patients with Recurrent Sinusitis

Objective:To investigate the objective evaluation system of nasal function changes in patients with recurrent sinusitis after revision endoscopic sinus surgery. Method:Sixty patients with recurrent sinusitis underwent revision endoscopic sinus surgery. The Lund-Kennedy endoscopic sinus score and Lund-Mackay paranasal sinus CT score were performed before surgery, 3, 6 and 12 months after surgery. The saccharin test was used to evaluate the nasal mucosa ciliary moving function（nasal mucosal ciliary motor velocity） before surgery, 6 and 12 months after surgery. The correlation of objective evaluation indexes before and after surgery was analyzed. Result:The Lund-Kennedy endoscopic sinus score and Lund-Mackay paranasal sinus CT score of patients 3, 6, 12 months after surgery were lower than those before surgery（P<0.05）; The Lund-Kennedy endoscopic sinus score and Lund-Mackay paranasal sinus CT score of patients 6 and 12 months after surgery were lower than those 3 months after surgery（P<0.05）; The Lund-Kennedy endoscopic sinus score and Lund-Mackay paranasal sinus CT score of patients 12 months after surgery were lower than those 6 months after surgery（P<0.05）. The nasal mucosal ciliary motor velocity of patients 6 and 12 months after surgery was lower than that before surgery（P<0.05）; The nasal mucosal ciliary motor velocity of patients 12 months after surgery was lower than that 6 months after surgery（P<0.05）. The Lund-Kennedy endoscopic sinus score was positively correlated with Lund-Mackay paranasal sinus CT score in patients before surgery, 3, 6 and 12 months after surgery（P<0.05）; The Lund-Kennedy endoscopic sinus score was negatively correlated with nasal mucosal ciliary motor velocity in patients before surgery, 6 and 12 months after surgery（P<0.05）; The Lund-Mackay paranasal sinus CT score was negatively correlated with nasal mucosal ciliary motor velocity in patients before surgery, 6 and 12 months after surgery（P<0.05）. Conclusion:There is good correlation among the Lund-Kennedy endoscopic sinus score, the Lund-Mackay paranasal sinus CT score and the nasal mucosal ciliary motor velocity in patients with recurrent sinusitis before and after revision endoscopic sinus surgery. This study establishes an objective evaluation system for evaluating the changes in nasal function with these three indexes as the main body.
