Objective To observe the clinical efficacy and safety of Biyuan Tongqiao granule combined with triamcinolone acetonide spray in the treatment of patients with chronic rhinosinusitis .Methods A total of 106 patients with chronic rhinosinusitis in the Traditional Chinese Medicine Hospital of Anji County from February 2015 to February 2017 were selected as study objects .According to different treatment plan , the patients were randomly divided into the control group and the combined group , with 53 cases in each group .The control group received triamcinolone acetonide nasal spray 220μg, 1 time/d, one week later , the dosage adjusted to 110μg, 1 time/d.The combined group was given Biyuan Tongqiao granules 15 g,three times /d on the basis of the treatment of the control group.The clinical efficacy,SONT -20,VAS score,paranasal sinus CT score and incidence rate of adverse reaction were analyzed before and after treatment in the two groups .Results The total effective rate of the combined group was 94.34％,which was higher than 81.13％ of the control group,the difference was statistically significant (χ2 =4.296,P=0.038).The SNOT-20,VAS and Lund-Mackey sinus CT score in the combined group were better than those in the control group,the differences were statistically significant (t=7.661,9.189,7.183, 9.269,10.470,all P<0.05).The incidence rate of adverse reactions in the two groups was 7.55％,the difference was not statistically significant (χ2 =0.000,P =1.000).Conclusion Biyuan Tongqiao granule combined with triamcinolone acetonide spray in the treatment of patients with chronic rhinosinusitis can improve the clinical efficacy and reduce pain of patients ,it is worthy of popularization and promotion in clinical .
