Clinical Curative Effect of Temperature-controlled Radiofrequency Ablation on Allergic Rhinitis

Objective To observe the clinical curative effect of low temperature radiofrequency ablation(RFA) in treating allergic rhinitis which was not caused by dust mites.Methods Sixty patients of allergic rhinitis took skin prick test which showed positive less than(++) for dust mites from October 2008 to October 2009.The patients were not taking any allergy or cold medicine in the next week.They were treated by RFA at bilateral agger nasi,nasal septum before the top of the ethmoid nerve,1 to 2 point of turbinate,2 to 3 point of inferior turbinate with the help of nasal endoscope.Its curative effects were evaluated as well one month and a year after operation.Results After one month follow-up,24 patients with symptoms and signs of improvement rate ≥66%,markedly effective,40% of the total;36 patients with symptoms and signs of improvement rate between 65% and 26% for the effective,accounting for 60%;the total efficiency ratio was 100%.After one year follow-up,21 patients with symptoms and signs of improvement rate ≥66%,markedly effective,35% of the total;30 patients with symptoms and signs of improvement rate between 65% and 26% for the effective,accounting for 50%;the remaining nine cases with symptoms and signs of improvement rate ≤25%,as invalid,15% of the total,with a total effective rate was 85%.Conclusion The low temperature radiofrequency ablation is worth to be used in clinical for its simple,safety and practical in treating allergic rhinitis.
