AIM: To study the treatment effect of chronic pharyngitis using radiofrenquency and compound iodine glycerin. METHODS: If the patients were diagnosed as chronic simple pharyngitis and atrophic pharyngitis or pharyngitis sicca,they were treated with smearing compound iodine glycerin on the back wall of pharynx, combining with general treatment. If the patients were diagnosed as chronic hypertrophic pharyngitis, they were treated with radiofrenquency, combining with general treatment. The control groups were only treated with general treatment. RESULTS: Half a month post treatment, 268 cases were recovered (82.0%) among 327 patients; 56 cases were better (17.1%). In the control groups, 62 cases were healed (62.0%). The effect of the treatment using radiofrenquency or compound iodine glycerin is significantly better than that in the control groups (P<0.0001). CONCLUSION: Treatment of chronic simple pharyngitis and atrophic pharyngitis or pharyngitis sicca with smearing compound iodine glycerin on the back wall of pharynx, and the treatment of chronic hypertrophic pharyngitis using radiofrenquency are more effective than routine method. Their advantages are local treatment, accurate localization, simple process, short therapy duration, no bleeding and pain, higher cure rate.
