To investigate the clinical efficacy of "Zhuyuan soup" by combination with fumigation and oral administration on chronic rhinosinusitis（CRS）, further exploring effective Chinese medicine for the disease, and giving full play to the unique advantages of external treatment of traditional Chinese medicine. By using randomized and positive drug controlled methods, patients with moderate-to-severe chronic rhinosinusitis were randomly divided into western medicine group and traditional Chinese medicine group, 30 cases in each group. In the western medicine group, the nasal spray hormone Budesonide was used, and the patients in the traditional Chinese medicine group were treated with the traditional Chinese medicine prescription"Zhuyuan soup"by combination with fumigation and oral administration. All of the above patients were followed up for 2 weeks, and 1 course for 1 month. Visual analogue scores were taken at each follow-up, and CT and nasal endoscopy were performed before and after treatment. The total effective of "Zhuyuan soup" group was 67.1%, which was higher than that of western medicine group（59.6%）, but there was no statistically significant difference（>0.05）. After treatment, there were no significant differences between the two groups with regard to the symptom of nasal congestion, dizziness, facial pain or fullness, dysosmia, nasal discharge or postnasal drip, total sensation, total symptom score（>0.05）. According to the total symptom score, the effect of the two groups of patients was not significantly correlated with the gender, age, course of disease, alcohol and tobacco hobbies, previous medication and surgery（>0.05）. Based on the results of the study, we found that the Chinese medicine group is superior to the western medicine group in improving the total feeling of the disease, dizziness or headache, facial pain or fullness, and postnasal drip, olfactory disorder. Both traditional Chinese medicine and western medicine are effective methods for treating chronic rhinosinusitis. Clinically, individualized comprehensive treatment should be carried out according to the patient's condition. The above methods may be applied alone or in combination with Chinese and Western medicine. Further optimization and improvement of the combination of traditional Chinese and Western medicine in chronic sinusitis can help improve the clinical efficacy and satisfaction of patients, which deserves further study.
