Objectives: The purpose of this study is to examine 33 cases of chronic sinusitis in children who were treated with Korean medicine. Methods: Herbal medicine, acupuncture, and nebulizer and laser therapy were used to treat chronic sinusitis, and a plain radiography (paranasal sinus water's view) was used to confirm improvement of the children's sinusitis. Then, the data was classified by sex, age, frequency and duration of common cold, severity of sinusitis, duration of treatment, pattern identification and so on. Results: There were 72.7% boys and 27.3% girls. The average age of children is 4.48 ± 2.18 years. 70% of the children had common cold more than once a month, and 85.1% of the children from the study group had common cold lasting more than a week. The sinusitis severity score ranged from 10 to 200. 81.8% were more than 100. Duration of the treatment was 157.21 ± 83.4day, duration of herbal medicine treatment was 79.3 ± 31.23day, rate of herbal medicine was 62.12 ± 29.21%. The frequency of acupuncture, nebulizer and laser therapy ranged from 1 time to 11 times but was much lower than expected. Conclusions: 33 cases of chronic sinusitis in children were treated with Korean medicine, and cure of the illness was confirmed by PNS water's view, and clinical characteristic of the patients with chronic sinusitis was analyzed.
