Abstract:Objective To investigate the effect of nasal endoscopic plasma RF posterior nasal dissection in moderate to severe persistent allergic rhinitis. Methods 80 patients with moderate and severe allergic rhinitis were admitted in Weihai Municipal Second Hospital from January 2015 to January 2018, Of these, 46 were combined with simultaneous nasal septal deviation, All patients underwent a postnasal neurotomy using plasma RF, At the same time, the lower rhinoplasty performed; In 46 patients with nasal septum, Observe the improvement of allergic rhinitis before and after surgery. Results were 100% effective after 1 year follow-up, 2 Years with 95% Efficiency, 3 Years of Efficiency of 88.75%, The overall score of VAS after 1,2 and 3 years improved significantly compared with before surgery, Within 3 years with extended extension, Treatment efficiency has decreased year by year, The total VAS score rose year by year. Conclusion The effect of combined with nasal sepcorrection and inferior rhinomeplasty on moderate and severe allergic rhinitis. the long-term effect still needs to be further studied.
