Objective To explore the clinical efficacy on injecting medicament into inferior turbinate for the treatment of allergic rhinitis with diprospan.Methods 78 patients with allergic rhinitis enrolled in the study.To inject 3 ml medicament(2 ml 10%sodium chloride,0.5 ml 2%lidocaine,0.5 ml diprospan)into inferior turbinate each side.Before injection and in 5 months after injection,nasal obstruction,nasal tickles,sneeze and snot were investigated by visual analogue scale(VAS).It was obvious efficacy if the score over 5 and efficacy if the score over 3 score,below 3 was non-effective.Results In 5 months after injection,16(20.5%)cases were effective obviously,54(69.2%)cases were effective,8(10.3%)cases were non-effective,11(14.1%)cases did not recurrent followed up for 2 years.Conclusion Injecting medicament into inferior turbinate is one of the valid,feasible methods of the treatment of allergic rhinitis.
