Abstract:   (253 Views)
Background: Rhinosinusitis is an inflammatory disease of the nasal and paranasal sinus mucosa, and it becomes chronic when it lasts longer than 3 months without symptom improvement.  The aim of this study was to determine the effect of PRP on improvement of endoscopic sinus surgery. 
   Methods: This was a randomized clinical trial (RCT) designed and implemented on 21 patients with chronic rhinosinusitis in Rasool Akram hospital in Tehran during 2016-2017. In this study, one side of the nose was randomly selected as the control and the other side as the case, and at the end of the surgery, PRP was sprayed onto the surface where the polyp was removed in the side that was intended as the case. The nasal endoscopy findings were graded according to Meltzer’s criteria before and after surgery and CT findings were classified according to the Lund-Mackay scoring system. Then, all patients were followed for 6 months. The SNOT-22 questionnaire, charts of Meltzer’s criteria, and Lund-Mackay were used for data collection. Kolmogorov–Smirnov test, Wilcoxon Signed Rank test, and Mann-Whitney U test were used to analyze data in SPSS-22 software. P value<0.05 was considered significant.
   Results: The mean and standard deviation of patients' age were 36.55 and 7.91, respectively. The median Lund-McKay Pre-op CT score before treatment was 10 (9.5-11), and no significant difference was found between the 2 sides of the nose (left and right). The items that showed statistically significant improvement after surgery was SNOT-22 (p<0.05). The mean of Meltzer scores in each side of the nose was significantly different before and after intervention (p<0.05). However, the mean of Meltzer scores in the 2 sides of the nose was not significantly different before and after intervention.
   Conclusion: The treatment by PRP may be effective in reducing symptoms of patients showing recurrence of CRS symptoms following endoscopic sinus surgery subjectively but not objectively.
